Abstract:

Twelve mollusk species from late Jurassic to Oligocene cold seep deposits are described and illustrated. Nine of them are new, two have already been named, two new genera are introduced, and one species is described only in open nomenclature. Puncturella (sensu lato) mcleani sp. nov. and Fissurella (sensu lato) bipunctata Stanton, 1895 are the only confirmed fissurellids in fossil cold seeps. The sutilizonid Triassurella goederti sp. nov. is similar to the modern ventinhabiting Sutilizona and the Late Triassic shallow-water reef-inhabitant Triassurella carnica. A smooth, late Jurassic neritid is the oldest neritid from fossil seeps and probably represents an independent neritid radiation into the seep environment, without close phylogenetic connection to the modern Bathynerita. The four new abyssochrysoid caenogastropods Humptulipsia macsotayi, Hokkaidoconcha novacula, Paskentana anistratenkorum, and P. umbilicata significantly extend the stratigraphic and geographic ranges of these apparently seep-restricted genera. Four bivalves are described, including the new modiomorphid Caspiconcha rubani from the early Cretaceous and the new bathymodioline Bathymodiolus (s.l.) palmarensis from the Oligocene. Among the lucinids, the oldest seep-inhabiting lucinid (late Jurassic) is described as Beauvoisina carinata gen. et sp. nov.; the new genus Cubatea is introduced for an Oligocene lucinid from Cuba. It is suggested that Caspiconcha, Paskentana, and hokkaidoconchids constitute the core of a seeprestricted fauna that inhabited seeps worldwide from (at least) late Jurassic to early Cretaceous time. These taxa are, at the family level, phylogenetically unrelated to the modern vent and seep fauna.

Abstract:

Brachiopods generally have not been considered to be typical or significant faunal components of modern or ancient hydrothermal vent and cold-seep settings. The Early Cretaceous (Neocomian) rhynchonellide brachiopodPeregrinellahas long been viewed as a paleontological curiosity because of its distinctive morphology, status as the largest Mesozoic brachiopod, anomalous stratigraphic associations, and widespread, yet discontinuous paleogeographic distribution. Examination of all worldwidePeregrinellaoccurrences (14) indicates restriction of this brachiopod to ancient cold-seeps. It is probable thatPeregrinellagrew to large sizes in such great abundances at fossil cold-seep sites because of a richly organic food supply generated by localized fluid seepage and bacterial chemosynthetic activity. Living brachiopods are not known to harbor chemosymbiotic bacteria in their tissues; however, direct chemoautotrophic utilization of reduced fluids byPeregrinellacannot be rejected or demonstrated at present.Peregrinellaoccurs at widely separated cold-seeps of Neocomian age (e.g., California, Mexico, Tibet, Europe), yet its mode of dispersal and larval development is unknown. In modern hydrothermal vents of the deep-sea, organism dispersal occurs along oceanic ridges, where benthic faunas display both planktotrophic and nonplanktotrophic larval-mode types.Peregrinellamay represent a Mesozoic relic of a long-lived “lineage” of vent-seep associated rhynchonellides from the Paleozoic (e.g., ?Eoperegrinella, Dzieduszyckia), but major gaps in the stratigraphic record between these rhynchonellide occurrences, and the lack of rigorous phylogenetic analysis for these groups preclude a clear resolution of the origin(s) of vent-seep brachiopods at present.

Abstract:

The genus <i>Provanna</i> (belonging to Superfamily Abyssochrysoidea) is a group of globally distributed gastropods commonly discovered in the deep-sea chemosynthetic environments. To date it is composed of 29 extant and nine fossil species and all of them seem to be endemic to vents, seeps or organic falls. Despite the increasing interest in cold seeps in South China Sea in recent decades, how this genus is distributed in this area is largely unknown. A new fossil species, <i>Provanna dongshaensis</i> sp. nov., collected from the hydrate-bearing sediments in the cold seep area of northern SCS, was studied. A basic morphological description together with the observation of shell microstructures was made, and a brief comparison to known <i>Provanna</i> species was summarized. The occurrence depths of this new species are consistent with the remarkable negative carbon isotope of carbonate layers, which mutually supports the relationship to the ancient seep. Such sedimentary samples from drilling cores may be potentially better materials for systematic research of deep-sea gastropods and other chemosynthesis fauna.

Abstract:

AbstractThree isolated limestone deposits and their fauna are described from a middle Eocene Flysch succession in northwestern Istria, Croatia. The limestones are identified as ancient methane-seep deposits based on fabrics and characteristic mineral phases, δ13Ccarbonatevalues as low as −42.2 ‰ and13C-depleted lipid biomarkers indicative of methane-oxidizing archaea. The faint bedding of the largest seep deposit, the great dominance of authigenic micrite over early diagenetic fibrous cement, as well as biomarker patterns indicate that seepage was diffusive rather than advective. Apart from methanotrophic archaea, aerobic methanotrophic bacteria were present at the Eocene seeps as revealed by13C-depleted lanostanes and hopanoids. The observed corrosion surfaces in the limestones probably reflect carbonate dissolution caused by aerobic methanotrophy. The macrofauna consists mainly of chemosymbiotic bivalves such as solemyids (Acharax), thyasirids (Thyasira) and lucinids (Amanocina). The middle Eocene marks the rise of the modern seep fauna, but so far the fossil record of seeps of this age is restricted to the North Pacific region. The taxa found at Buje originated during the Cretaceous Period, whereas taxa typical of the modern seep fauna such as bathymodiolin mussels and vesicomyid clams are absent. Although this is only a first palaeontological glimpse into the biogeography during the rise of the modern seep fauna, it agrees with biogeographic investigations based on the modern vent fauna indicating that the dominant taxa of the modern seep fauna first appeared in the Pacific Ocean.

Abstract:

Cold seep carbonates are important archives of pore water chemistry and ancient methane seepage activity. They also provide an important contribution to the global carbon sink. Seep carbonates at three sediment layers (3.0, 52.1, and 53.6 mbsf) were collected at site W08B in the Qiongdongnan Basin of the South China Sea. This study investigated the mineralogy, microstructure, stable carbon and oxygen isotopes, trace elements, and U-Th dates of these carbonates to identify the relationship between methane flux and authigenic carbonate precipitation. The results showed that the δ13C and δ18O values of all carbonates are similar, indicating that the carbon source for shallow carbonates and deep carbonates has remained constant over time and included biogenic and thermogenic methane. Although carbonates were found in three sediment layers, the two main stages of methane seepage events were discernible, which was likely caused by the dissociation of gas hydrates. The first methane seep took place at 131.1–136.3 ka BP. During a dramatic drop in the sea level, the seep carbonate at 52.1 mbsf formed at 136.3 ka BP through the anaerobic oxidation of methane (AOM). The carbonate at 53.6 mbsf resulted from the vertical downward movement of the sulfate-methane transition zone with decreasing methane flux at 131.1 ka BP. This is the reason for the age of carbonates at 52.1 mbsf being older than the age of carbonates at 53.6 mbsf. The second methane seep took place at 12.2 ka BP. Shallow carbonate formed at that time via AOM and is now located at 3 mbsf. Moreover, thin-section photomicrographs of deep carbonate mainly consisted of matrix micrite and biological debris and acicular aragonite occurred as vein cement filling the pore spaces between the matrix micrite. The acicular aragonite was mainly influenced by the timing of the carbonate precipitation of minerals. This research identified a long history of methane seep activity reflected by the vertical distribution of carbonates.

Abstract:

Tubes suspected to be those of vestimentiferan worms are abundant in carbonate boulders at one locality in the lower Oligocene part of the Lincoln Creek Formation along the Canyon River, Grays Harbor County, Washington. The largest tubes exhibit the same general orientation and are arranged in clusters. The tube walls are preserved as aragonite that is, in some cases, replaced by silica. The original tube walls either had a high carbonate content or were indurated very early by aragonite mineralization of the organic wall. The carbonate cements around, on, and inside of the tubes were precipitated due to the microbial oxidation of hydrocarbons at a cold-seep. After lithification, the carbonate fragmented as it slid or slumped, along with other sedimentary debris, downslope into deeper waters. This is one of the few reports of an ancient cold-seep chemosynthetic community dominated by tube worms, and the third report of an allochthonous cold-seep carbonate within a deep-water depositional setting.

A limited fauna of relatively simple, thin-walled, hexactinellid sponges, including moderately coarse-textured, funnellike Hexactinella(?) conica new species, fine-textured, tubular to branched Hexactinella(?) tubula new species, fragments of delicate Eurete goederti(?) Rigby and Jenkins, 1983, and Farrea(?) species, has been found in the Oligocene Lincoln Creek Formation on Canyon River, in the southcentral part of the Olympic Peninsula, Washington. These sponges dominate a chemosynthetic invertebrate assemblage that included the gastropod Provanna antigua Squires, 1995; the polyplacophoran Leptochiton alveolus (Lovén, 1846), and radiolarians. Most of the sponges are preserved as silica in a localized cherty and botryoidal, calcareous cement-filled limestone formed at bathyal depths by bacterial oxidation of methane at a cold seep. This is the third known report of sponges from ancient chemosynthetic deposits.

Abstract:

The Karystia, a region of southern Euboea directly across from the Attic mainland, features two peninsulas that are dry and agriculturally poor compared to the fertile plains found elsewhere in the region and on the island (Figure 1). Despite the aridity of this area, however, an unusual pattern of human activity was revealed during archaeological investigation and extensive survey carried out in the 1980s and the 1990s. The Paximadi peninsula was first explored by Donald Keller during his dissertation research between 1979–1981, and between 1986–1993 the Southern Euboea Exploration Project (SEEP) continued work on both the Paximadi and the Bouros-Kastri peninsulas. These surveys recorded a dispersed settlement pattern of single farmsteads, along with an exceptionally high number of tower structures on the two peninsulas that flank ancient Karystos—a site now identified with the modern town of Paliochora (Figure 2). The majority of the towers date to the Classical period, though others range from the Archaic through Ottoman periods. At present, only the towers of Paximadi have been published, so their connections with those of Bouros-Kastri and with the broader Aegean have yet to be fully elucidated. This paper reviews different explanations for the unusually high density of Classical-period towers in this region, contextualizes the towers within the period of classical antiquity to which they are most likely to belong (the 5th century BC), and presents a new interpretation of nearly three-decade-old data that underscores the importance of the Karystia in the ancient Aegean.

Abstract:

Lake Baikal (LB) is the only freshwater ancient lake on Earth where animals inhabit all bathymetric zones down to the deepest sites (approximately 1640 m). However, there is very little data on the composition of their abyssal harpacticoid fauna. On the basis of the samples collected in LB in 2010–2017 at a depth of 270–1632 m, analysis of the fauna composition and species diversity of harpacticoids in the deep-water zone is presented. Studies were conducted in all parts of the lake, including areas of a hydrothermal, oil–methane seeps, and mud volcanoes. Nineteen Baikal endemic morphological species of the genera Bryocamptus, Attheyella, and Moraria (Baikalomoraria) were found. A brief description of the taxa morphology is presented. The genus Bryocamptus was the richest by species number at the studied sites, and Bryocamptus smirnovi Borutzky was the most frequent. The most diverse (8 species) was the fauna of the Saint Petersburg methane seep. Studies have shown that the taxonomic diversity of harpacticoid copepods in the deep-water zone of LB is lower than in its littoral zone. According to two non-parametric species estimators (Chao 2 and Jackknife 1), a 1.5-fold increase of species richness of harpacticoids of the LB abyssal is expected.

Abstract:

Introduction and approachBacterial endospore distributions in marine sediments are influenced by geological conduits providing routes for subsurface to surface microbial dispersal. To examine this phenomenon in more detail, endospore abundance was determined by quantifying the biomarker 2,6-pyridine dicarboxylic acid (dipicolinic acid or DPA) in 16 deep sea sediment cores from hydrocarbon prospective areas in the NW Atlantic Ocean. DPA is specific to endospore-forming bacteria from the phylum Firmicutes and constitutes a significant percentage of endospore dry weight. DPA is therefore a potential biomarker for sediment dwelling endospores and geological conduits.Piston cores (10), gravity cores (3) and box cores (3) were collected during two expeditions to the Scotian Slope in the NW Atlantic Ocean off the east coast of Canada aboard the CCGS Hudson in 2016 and 2018 (Campbell (2016), Campbell and Normandeau (2018), Campbell and MacDonald. (2016)). Sampling sites were 1970 to 2791 m water depth, with piston cores (n=3) ranging from 344 to 953 cmbsf and gravity cores (n=10) ranging from 43 to 739 cmbsf, box coring captured the top 25 cmbsf. To address the efficacy of DPA biomarker analysis as a tool for hydrocarbon seep location we established a modified Tb3+ chelation method (Lomstein and Jørgensen (2012), Rattray (2021)). Sediment samples were extracted using acid hydrolysis, chelated with Tb3+ and analysed using HPLC fluorescence, measuring at 270 nm emission and 545 nm excitation. DPA concentrations were converted to Endospore numbers were calculated using 2.24 fmol DPA per endospore (Fichtel 2007), a conversion factor routinely used in other studies (Braun 2017, Gittins 2022, Heuer 2020, Lomstein 2012, Rattray 2022, Wörmer 2019, Lomstein and Jørgensen 2012). DPA concentrations were compared with measurements of over 250 different gaseous and liquid hydrocarbon compounds used to assess for the presence of thermogenic hydrocarbons.Results and discussionSamples and locations were assessed as being thermogenic hydrocarbon gas positive (stations 16-41, 18-07) or thermogenic hydrocarbon negative based on the abundance of C1-C5 hydrocarbons in sediments sampled from the same cores. Station 18-14 contained hydrocarbons from biogenic origin. Station 18-06 is the only site with higher endospore abundance but that was determined to be hydrocarbon negative.Deep water Scotian Slope sediment cores show high endospore abundance correlates with thermogenic hydrocarbon seeps (Fig. 1). Cores from locations lacking evidence for thermogenic hydrocarbons generally contained significantly lower endospore abundances, with the notable exception of site 18-06. This potential paleoenvironmental hydrocarbon seep site highlights the utility of a DPA proxy for potentially identifying ancient hydrocarbon seeps and investigating past geological systems. The association of high endospore abundances with thermogenic hydrocarbons and the quantity of gas expulsion points to an interesting new biological tool for understanding hydrocarbon seepage in the deep biosphere, based on DPA assays in marine sediments.

Abstract:

The article presents the data of landscape studies of the territory of the Ust-Selenginsk depression. It was formed at the beginning of the Paleogene period and became the historical core of the development of the Baikal rift zone. From the north and west, the research area is limited by large tectonically active faults, along which ascending geothermal flows seep. In the areas of their impact, changes in air and soil temperatures are recorded. The widespread development of mud volcanoes has also been noted here. The research area is characterized by peculiar and contrasting natural conditions, which determines the high degree of vulnerability of landscapes and the possibility of their irreversible transformations. It has been established that the modern tectonic lowering of the area contributes to its waterlogging. The drainage system in the area of the foothills of KhamarDaban and the left bank of the Selenga enhances the processes of soil salinization. Sands and loesslike deposits on ancient terraces and the right bank of the Selenga are influenced by Aeolian processes and turn into dunes when vegetation is destroyed. The high tectonic activity of the territory and the weak stability of the landscapes exclude the possibility of active economic activity within its borders.The problem associated with the implementation of environmental protection measures and human activities is characteristic. Its solution can be implemented based on knowledge about the features of landscape transformation.

Abstract:

As an artist working primarily with sculpture, I ask how colour might evoke new sensibilities where ethical, non-subjective dimensions, bring us into deeper relations with the world. Consideration is given to how Deleuze’s thought on colour might prove more than an explication of art as sensation, precept and affect to become an ethical encounter with life through which to build new capacities for imagining and a world to come. In the week before Christmas 2023 I am in Athens. Television images screen the IDF invasion of Gaza. While wandering through the Acropolis Museum I wonder how the stains of the red pigment hematite (from the Greek word for blood: haima) on the drapery of an ancient marble sculpture might translate vision into a form of touching so that when seeing, on a screen, images of a woman in Gaza holding a dead infant in a bloodstained shroud, I might better pay attention. Not to aestheticise suffering by reducing it merely to a red stain on white cloth. Not to see it as an inevitable outcome of violence, a generality, but rather to let the specificity of sorrow and pain in this image seep into my own flesh. I experiment with materials, form and colour to make a sculpture installation that touches on the capacity of small children in Gaza to create momentary milieus of joy and optimism from gleaned scraps of rubbish and the environment.

Abstract:

The evaluation of speeches in ancient histories by modern scholars is very varied. Tarn (p. 286) opened his discussion of ‘The speeches in Arrian’ with the following words:Speaking generally, one expects a speech in any ancient historian to be a fabrication, either composed by the historian himself or by a predecessor, or else some exercise from one of the schools or rhetoric which he had adopted.On the other hand, according to Fornara (p. 143), ‘the fact does not seem to have been sufficiently appreciated that the ancients unfailingly endorsed the convention that speeches must be reported accurately’. When Fornara made a generalization, he wrote as follows:The ancients had unanimously adopted the Thucydidean principle of honest reporting of the things that were said as well as the things that were done.

Abstract:

Among the animal patterns on the bronzes of the Dian Kingdom, the cow and the snake are the most common and  representative visual symbols. They have strong visual tension, expressiveness and artistic appeal, showing the unique artistic  aesthetics and ideas of the ancients of Dian Kingdom, and They all have specific meanings and contexts. This article mainly  explores the decorative symbols of animal decorations in Yunnan bronzes, and uses “ox” and “snakes” as the main objects to  analyze semantics and context.Methods:This article first elaborates on the types and decorations of ancient Dian bronzes, and then  elaborates on the characteristics and symbolic meanings of cow and snake patterns by listing some representative Dian bronzes;  finally, it is in-depth with the semantics and context of visual symbols. Analysis. Result:The types of animal images on the bronze  ware of Yunnan culture are rich and diverse, and each animal has different shapes and forms, and has its own symbolic meaning and  function. This also reveals the relationship between man and nature from the side, reflecting the ancient people of Yunnan’s sacrifices  and sacrifices. The social and economic conditions such as hunting and breeding record the trivial life of the ancients. The animal  decoration art of the Dian Kingdom has a very strong ethnic customs and regional characteristics. It depicts the intense scenes of  animal daily life and fighting in detail. The animal’s shape, demeanor and own characteristics are all vividly shaped, with a strong  artistic atmosphere and visual tension. To a large extent reflects the aesthetic concept and ideological pursuit of the ancients of Dian  Kingdom. Conclusion:The two visual symbols of the cow pattern and the snake pattern are the records of the people of the ancient  Dian kingdom on nature and life, and they also carry the ancient people’s feelings for nature. They reflect the religious beliefs and  ideas of the ancient Dian civilization and have local characteristics and customs. , It is the spiritual sustenance of the ancient Dian  people to seek advantages and avoid disadvantages.

Full text

Abstract:

This article discusses three trial scenes from three different ancient Greek novels (by Chariton, Achilles Tatius, and Longus), in which naïve justice seems to be deliberately subverted. The titular concept of “naïve justice” is defined here in terms borrowed from Aristotle’s Poetics, where the term “double resolution” is used, disparagingly, of plots in which the good characters are all rewarded and the bad characters all punished. The argument is made that the trial scenes under discussion should raise doubts in the reader’s mind as to which of the parties is truly guilty, and which is truly innocent. This can be seen as a reflection of unexpectedly mature ethical sensibilities on the part of these often-underestimated writers, who seem to have grasped that the “double resolution” may make the reader feel good, but has little to do with the real world.

Abstract:

The article notes that Buddhism and Islam, which are currently the main world religions in the region of Southeast Asia, including Malaysia, are among the main religions, the spread of these religions also had its own characteristics, like Hinduism, in contrast to the processes that took place in other countries, although the Islamization of the region has continued for decades, even centuries, the region has not seen Arab military action. With the spread of Islam in the region of Southeast Asia, it developed under the influence of the religions that existed there, and over time began the process of syncretization with the customs of other surrounding religions. It is noteworthy that at the time of the penetration of Islam, the population accepted it not as a foreign religion, but as a pre-existing belief.

Abstract:

The earliest recorded dreams show that they were seen as part of a religious worldview, either as messages from the gods or as visitations by spirits and the gods themselves. The ancients made sense of dreams not as indicators of the dreamer's psychological state, but as real encounters with the spirit world and the sacred realm. In this article I examine how both of these perspectives on dreams, the ancient religious view and the more recent psychological view, have been treated in the psychology of religion, based on a review of the major English-language texts in the psychology of religion since 1970 and developments in dream research during the last 25 years.

Abstract:

AbstractThis study investigates how methodological aspects of seed-bank sampling affect seed-bank records in temperate deciduous forests. We focused explicitly on seed-bank records of ancient forest species, which are assumed to lack a persistent seed bank; a hypothesis suspected to be partly due to methodological shortcomings. Through a quantitative review of 31 seed-bank studies in temperate deciduous forests of central and north-west Europe, we quantified the role of sampling methodology in constraining total seed-bank records and seed-bank records of ancient forest species (γ-diversity, average species' retrieval frequency and average seed density). A major methodological trade-off was established between sampled plot area and the number of plots: at an increased number of plots, the area sampled per plot decreased significantly. The total surface area sampled in a study was the primary determinant of γ-diversity, both for overall species richness and for ancient forest species richness. A high retrieval frequency of ancient forest species indicated that few plots were intensively sampled. The parallel increase in total species richness and ancient forest species richness and the non-significance of their ratio in relation to methodological variables suggests that ancient forest species are not particularly rare in the seed bank compared to other species. These results imply that sampling methodology has a far-reaching impact on seed-bank records such as γ-diversity, the detection of ancient forest species and ultimately seed-bank composition. We formulate a set of guidelines to improve the quality of seed-bank studies in temperate deciduous forests.

Abstract:

The institution of slavery was characteristic of all the civilizations from Mediterranean basin in ancient times. However, slavery had its widest application in the Roman state, for which it was of immense importance, since slaves were seen as the driving force of Roman social and economic system. Slaves (servus, puer) were treated as “speaking tools” (instrumentum vocale). The position of the individual in the Roman state was regulated in detail, and there were three special positions: status civitatis (Roman citizen or foreigner), status familiae (elder of the family or its member under the rule of pater familias) and status libertatis (slave or free man). Slaves had a special legal status in Roman law at the time. Unlike animals and things over which power was referred to as domicium, this was about power over man, so the term domicia potestas was used. In the initial stages of the development of state and the law, they were viewed exclusively as property, without any personal, property or other rights. Thus the puer could not be a party to the proceedings, and his union with the slave girl was treated as a de facto union (contubernium), not as a valid marriage. He could only improve the position of his master, and if the servus would cause some damage to a third party, the master was not obliged to eliminate it, but according to Aquilius law of damage from 287 AD there was a possibility of handing over the slave to the injured party according to the principles of noxal liability. An individual could find himself in the status of a slave in three ways: by falling into captivity in war, by being born to a slave mother (vernae) or by losing his freedom as a form of sanction. In addition to private and royal, there were also so-called public slaves (servi publici). Their owner was not a private person, but a wider social community, and power over them was officially exercised by the Roman people (populus Romanus), civilian authorities in municipalities or colonies in Italy and its provinces. Servi publici were most often employed by magistrates or priests, and they also worked as guardians of various Roman buildings: basilicas, temples, archives and libraries. Roman law also knew of other forms of subordination that were not a form of slavery but states similar to it. The first aspect referred to persons in mancipio who were handed over by the pater famillias through mancipation to another elder as labor or to avoid tortious liability. The second case concerned addictus. Under the old civil law (ius civile) the addictus was a debtor in a certain obligatory relationship where, in case of non-payment of his obligation, he would be assigned to the creditor. The creditor had to keep him in the so-called creditor’s imprisonment for 60 days, until a guarantor appeared or the debt was repaid. If this did not happen, the debtor could be killed or sold as a slave. Persons redeemed from captivity (redempti ab hostibus) could be held captive by the redeemer until the ransom is paid either in money or by the work of the redeemed person. During the period of the empire, the duration of captivity of this kind could last for a maximum of 5 years. Gai Institutiones also classified auctoratus in these states. These included men, women and minor children who undertook to work for a person for a certain period of time (iudicati). Liberation from slavery was done through a special legal procedure (manumissio). In the early epochs of the ius civile, it was of an extremely formal nature, and with later praetorian activity this formalism was abandoned and replaced by new, more efficient legal means.
