Abstract:
Abstract. Pseudoscorpions, given their resemblance to scorpions, have attracted human attention since the time of Aristotle, although they are much smaller and lack the sting and elongated tail. These arachnids have a long evolutionary history but their origins and phylogenetic affinities are still being debated. Here, we summarise their fossil record based on a comprehensive review of the literature and data contained in other sources. Pseudoscorpions are one of the oldest colonisers of the land, with fossils known since the Middle Devonian (ca. 390 Ma). The only arachnid orders with an older fossil record are scorpions, harvestmen and acariform mites, plus two extinct groups. Pseudoscorpions do not fossilise easily, and records from the Mesozoic and Cenozoic consist almost exclusively of amber inclusions. Most Mesozoic fossils come from Archingeay and Burmese ambers (Late Cretaceous) and those from the Cenozoic are primarily from Eocene Baltic amber, although additional fossils from, for example, Miocene Dominican and Mexican ambers, are known. Overall, 16 of the 26 families of living pseudoscorpions have been documented from fossils and 49 currently valid species are recognised in the literature. Pseudoscorpions represent a case of morphological stasis and even the Devonian fossils look rather modern. Indeed, most amber fossils are comparable to Recent groups despite a major gap in the fossil record of almost 250 Myr. Baltic amber inclusions indicate palaeofauna inhabiting much warmer climates than today and point to climatic shifts in central Europe since the Eocene. They also indicate that some groups (e.g. Feaellidae and Pseudogarypidae) had much wider Eocene distributions. Their present-day occurrence is relictual and highlights past extinction events. Faunas from younger tropical amber deposits (e.g. Dominican and Mexican amber) are comparable to Recent ones. Generally, there is a strong bias in the amber record towards groups that live under tree bark, whereas those from litter habitats are underrepresented. We also discuss challenges in interpreting fossils: their cryptic morphology warranting novel techniques of morphological reconstruction, the massive gap in the fossil record between the Palaeozoic and Mesozoic, and problems with the classification of (historically) old amber material. Finally, we discuss aspects of the palaeoecology and biology of the fossils compared with the Recent fauna, such as phoresy.

Abstract:
ABSTRACTFossils in amber are a particularly important and unique palaeobiological resource. Amber is best known for preserving exceptionally life-like fossils, including microscopic anatomical details, but this fidelity of preservation is an end-member of a wide spectrum of preservation quality. Many amber sites only preserve cuticle or hollow moulds, and most amber sites have no fossils at all. The taphonomic processes that control this range in preservation are essentially unknown. Here, we review the relationship between amber groups and fossil preservation, based on published data, to determine whether there is a correlation between resin type and aspects of preservation quality. We found that ambers of different chemistry demonstrated statistically significant differences in the preservational quality and the propensity of a site to contain fossils. This indicates that resin chemistry does influence preservational variation; however, there is also evidence that resin chemistry alone cannot explain all the variation. To effectively assess the impact of this (and other) variables on fossilisation in amber, and therefore biases in the amber fossil record, a more comprehensive sampling of bioinclusions in amber, coupled with rigorous taphonomic experimentation, is required.

Four new species of fossil mermithids (Nematoda: Mermithidae) are described from amber: Heydenius arachnius n. sp. from a spider (Arachnida: Araneae) in Dominican amber, H. phasmatophilus n. sp., from a walking stick (Phasmatodea: Phasmatidae) in Baltic amber, H. podenasae n. sp. from a moth (Lepidoptera) in Baltic amber and H. trichorosus n. sp. from a caddis fly (Trichoptera: Leptoceridae) in Baltic amber. With previous descriptions of fossil mermithids from Diptera, Coleoptera, Hymenoptera and Hemiptera, there are now representatives of seven insect orders as hosts of fossil mermithids. With these additional four fossils, the total number of described nematode fossils is now 95, with 70 occurring in amber.

Abstract:
Fossil records of the subfamily Omaliinae are fragmentary and most of them are less informative compression fossils. Baltic amber from the mid-Eocene of northern Europe is one of the most important sources of insect fossils, but only two reliably placed omaliines have been described. Here, we provide a general overview of this subfamily in Baltic amber. In total, five new extinct species of four genera in three tribes are described and illustrated:Geodromicusbalticussp. nov.(Anthophagini),Eusphalerumkantisp. nov.(Eusphalerini),Paraphloeostibamorosasp. nov.,Phyllodrepadaedalisp. nov., andPh.icarisp. nov.(Omaliini). Additionally, we report on four species belonging toEusphalerum, which remain unnamed, from the same amber deposit. The records ofEusphaleruminclude the first fossils of the tribe Eusphalerini, while that ofGeodromicusmay represent the second and the first definitive fossil record of the genus and tribe Anthophagini. Our discoveries highlight the unexpected palaeodiversity of Omaliinae in Baltic amber, further reinforcing the coexistence of thermophilous and temperate-loving beetles in Baltic amber and potentially indicating wetland and riparian habitats of amber-producing forests.

Abstract:
The fossils once assigned to Raractocetus Kurosawa from the Mesozoic and Cenozoic amber deposits differ from extant Raractocetus in the longer elytra, the more strongly projecting metacoxae, and the hind wing with vein 2A forked. Thus, these fossils should be removed from Raractocetus. Cretoquadratus engeli Chen from Kachin amber appears to be conspecific with R. fossilis Yamamoto. As a result, R. fossilis and R. extinctus Yamamoto from Kachin amber, R. balticus Yamamoto from Baltic amber, and R. sverlilo Nazarenko, Perkovsky & Yamamoto from Rovno amber are transferred to Cretoquadratus Chen, as C. fossilis (Yamamoto) comb. nov., C. extinctus (Yamamoto) comb. nov., C. balticus (Yamamoto) comb. nov., and C. sverlilo (Nazarenko, Perkovsky & Yamamoto) comb. nov., and C. engeli syn. nov. is suggested to be a junior synonym of C. fossilis.

Abstract:
The identifications of known fossils currently placed in the lepidopteran superfamily Pyraloidea are critically re-examined. Of the eleven fossils examined, only three are confirmed to show morphological characters supporting placement in the superfamily. These fossils include a crambid larva in Baltic Amber, Baltianania yantarnia, Solis gen. n. et sp. n. and the oldest known fossil pyraloid, Eopyralis morsae Simonsen, gen. n. et sp. n. The third fossil, Glendotricha olgae Kusnezov, 1941, displays apomorphic characters for Pyraloidea, but is shown to be an inclusion in copal, not Baltic amber as had been reported. Seven fossil specimens lack reliable characters and cannot be assigned to Pyraloidea with certainty: Pyralites obscurus Heer, 1856; Pyralites preecei Jarzembowski, 1980; Petisca dryellina Martins-Neto, 1998; three fossil larvae tentatively identified as Pyralidae by Zeuner (1931); and Gallerites keleri Kernbach, 1967. A possible fossil pyraloid in Mizunami amber could not be located in museum collections and available literature does not provide details to assess the validity of the identification. We discuss the contribution of the reliably identified fossils towards better understanding the evolutionary history of Pyraloidea.

Abstract:
The recently reviewed subtribe Procirrina comprises eight extant genera with a predominately (sub)tropical distribution. Previous phylogenies consistently recover the tribe Pinophilini of the subfamily Paederinae monophyletic. No fossils of the tribe have been described, although compression fossils are known from the Cenozoic Green River Formation (50.3–46.2 Ma) as well as inclusions from the Miocene Dominican (20.43–13.65 Ma) and Mexican (20–15 Ma) ambers. Here we describe †Cretoprocirrus trichotos Jenkins Shaw and Żyła gen. et sp. n., the oldest fossil representative of the tribe Pinophilini, from Upper Cretaceous Burmese amber (ca. 99 Ma). Phylogenetic analyses of morphological data allow its unambiguous placement in the subtribe Procirrina. †Cretoprocirrus trichotos is the second genus of Paederinae described from Burmese amber and provides an important insight into the evolution of the subfamily.

Abstract:
Abstract. Rhopalosomatidae, currently considered the sister group of the Vespidae, are an enigmatic family of aculeate wasps that originated in the Late Jurassic or Early Cretaceous. Despite their considerable age, very few fossils of the family have been reported – all of them in amber (Miocene Dominican, Miocene Mexican, and mid-Cretaceous Burmese ambers). Here we report a new mid-Cretaceous rhopalosomatid wasp, Cretolixon alatum Lohrmann, gen. et sp. nov., from Burmese (Kachin) amber. This new genus has a unique mixture of characters, some of which are only known from the recent brachypterous genus Olixon and others of which are known only from the recent macropterous genera. Thus, Cretolixon Lohrmann, gen. nov. not only provides further evidence for the monophyly of the family but also contributes evidence for the monophyly of the Rhopalosomatinae. Key characters of the family are discussed, and an updated checklist of the world genera and fossil species and occurrences of Rhopalosomatidae is provided. Additionally, a chemical analysis was performed for three of the newly reported fossils as well as for the amber piece containing the rhopalosomatid larva described by Lohrmann and Engel (2017) to ascertain their amber vs. copal nature and their affinities with each other and previously described Burmese amber.

Abstract:
Extant Archaeidae, also known as pelican or assassin spiders, have an Austral distribution (South Africa, Madagascar and Australia), but were present in Eurasia during the Mesozoic and Cenozoic, as attested by fossils from Cretaceous Burmese amber (Ross A. 2019. Burmese (Myanmar) amber checklist and bibliography 2018. Palaeoentomology 2(1): 22–84) and Eocene European ambers (Wunderlich J. 2004. Fossil spiders in amber and copal: conclusions, revisions, new taxa and family diagnoses of fossil and extant taxa. Hirschberg-Leutershausen: Ed. Joerg Wunderlich, 1893 p.). They have been known to occur in Oise amber (Ypresian, early Eocene, MP7), from northern France. However, they are not abundant in Oise amber, and have been the subject of few studies until now. Here, we describe the only well-preserved, almost complete, archaeid fossil specimen. This adult male is described as Myrmecarchaea antecessor sp. nov, based on the presence of unique morphological features. The elongate petiolus and extremely long legs are characteristic of the genus Myrmecarchaea from the Middle Eocene Baltic amber. However, unique traits such as the thick, stout petiolus and the extremely elongated, posteriorly tapering cephalothorax distinguish it from the other species of Myrmecarchaea. This specimen is of high interest, as besides being a new species, it is also the first documented adult male in the genus, allowing us to observe sexual characters for the first time. Furthermore, it is the first occurrence of this genus outside Baltic amber, showing affinities between Oise and Baltic ambers, which are, otherwise, very different in their faunistic compositions, and further extends the known past range of the archaeid spiders.

Pasaulyje yra žinoma apie 150 fosilinių sakų rūšių. Didžioji jų dalis randama Šiaurės pusrutulyje, Europoje ir Amerikoje. Be to, vis daugiau fosilinių sakų aptinkama Azijoje, Afrikoje, Pietų Amerikoje.Vienas labiausiai paplitusių fosilinių sakų – Baltijos gintaras – nuo seno naudojamas papuošalų, buitinių ir liturginių reikmenų, smulkiosios plastikos gamybai, medžio, kaulo ir kitų dirbinių dekoravimui. Nuo XIX a. pradžios mėginta analizuoti gintarą, nesuardant jo pirminės medžiagos, tačiau nesėkmingai. Tik išaiškinta, kad gintarą sudaro alkoholyje tirpi dalis ir jokiame tirpiklyje netirpstantis likutis, pavadintas sukcinitu. Dabar gintaro chemijos tyrimams pasitelkiami nauji cheminės ir fizikinės analizės metodai: chromatografija, IR spektroskopija, branduolinis magnetinis rezonansas, masių spektroskopija ir kiti. Šio darbo tikslas buvo infraraudonosios spektroskopijos analizės metodu ištirti ir palyginti tarpusavyje kelių rūšių fosilinių sakų pavyzdžius iš skirtingų šalių archeologinių radimviečių: Baltijos pajūrio (Lietuva) „šiuolaikinį“ skaidrųjį gintarą, Benaičių ir Turlojiškių archeologiniuose kompleksuose (Lietuva) rastus archeologinio gintaro pavyzdžius, tamsųjį archeologinį Japonijos gintarą, fosilinius sakus iš Centrinio Libano archeologinės radimvietės ir fosilinius sakus iš Šiaurės Paryžiaus Orsi kvartalo archeologinės radimvietės.

Amber is a fossilized form of terpenoid resins. Unlike other fossil, amber is completely organic in nature, and its chemical composition remains almost constant over millions of years. Chemical characteristics of amber are a consequence of both biological origins and geological enviroment. Have been proposed different characterization techniques such as IR spectroscopy, NMR and other. By these methods chemical structure can be derived. However, these techniques do not allow totally exclusive distinction, because spectral differences cannot be universally established for all the samples. The main aim of this work was to characterize some samples of fossil resins from different countries. Six fossil resins were campared: ,,contemporary” Baltic transparent amber (Lithuania), archeological amber from Benaičiai and Turlojiškės (Lithuania), archeological amber from Japan, fossil resin from Central Lebanon and fossil resin from North Paris. These fossil resin were analyzed using IR spectroscopy method. IR spectra of fossil resin showed a presence of these groups: O─H (in polymers), ─CH3 and ─CH2─, ―Si─O─Si― or ―Si─O─C―. Come to a conclusion, the chemical structure and features of all analyzed fossil resin are similar. But they have the differences too. Fossil resins from Lithuania (Baltic transparent amber and archeological amber from Benaičiai and Turlojiškės) spectra have an absorption band at wavelength 1250-1175 cm-1, which is called ,,Baltic shoulder” by Beck.

Abstract:
Les travaux de cette thèse portent sur la caractérisation chimique des ambres provenant de plusieurs gisements d’âges et d’origines géographiques variés, dont certains sont inédits. Des protocoles identiques à tous les échantillons et combinant les analyses spectroscopiques (IR et RMN 13C) et chromatographiques (THM-CPG-SM) ont été appliqués, permettant d’identifier l’origine botanique des ambres et fournissant des indices pour la reconstitution des paléoenvironnements terrestres. La caractérisation chimique des gisements d’ambre du Jurassique supérieur (Kimméridgien) jusqu’au Crétacé supérieur (Santonien) du Liban, de Jordanie, du Congo, d’Equateur et de France, permet de proposer des biomarqueurs pour les résines de Cheirolepidiaceae, une famille exclusivement mésozoïque de Conifères. Une évolution des sources botaniques des résines produites durant le Mésozoïque et le Cénozoïque est alors discutée. Une production dominée par les familles de Conifères Araucariaceae et Cheirolepidiaceae est remarquée au Jurassique supérieur et Crétacé inférieur. La production au Crétacé supérieur est plutôt dominée par des Cupressaceae. Au Cénozoïque, les origines botaniques des ambres sont plus variées, et des familles d’Angiospermes sont à l’origine de nombreux gisements, dont l’ambre du Pérou produit par une Fabaceae. La production par des Conifères reste toutefois importante au Tertiaire, à l’exemple des ambres de Nouvelle-Zélande qui ont pour origine les Araucariaceae. Les données obtenues ont permis une ré-évaluation de la classification des ambres par Py-GC-MS. Ainsi, une nouvelle molécule dont la structure est inconnue encore, a été identifiée dans les chromatogrammes d’ambres de classe Ib et Ic, ajoutant un caractère discriminant entre ces deux sous-classes. Enfin, la relation âge / maturation des résines fossiles est discutée, qui dépend avant tout des conditions d’enfouissement des résines. Une large base de données moléculaires est ainsi établie pour un grand nombre de gisements d’âges et d’origines botaniques variés, qui permettra une comparaison globale dans les travaux futurs
This work focuses on the chemical characterisation of amber from different outcrops from different localities, and varied ages. Some of these outcrops had never been studied. All the amber samples were analysed with the same analytical techniques. The combination of the data obtained from spectroscopic (IR and 13C NMR) and chromatographic (THM-GC-MS) analysis allows the identification of the botanical origin of the amber and provide some information, for the reconstruction of the palaeoenvironment. Biomarkers for the cheirolepidiaceous resins were proposed based on the chemical characterisation of different amber outcrops dating from the Upper Jurassic (Kimmeridgian) to the Upper Cretaceous (Santonian) from Lebanon, Jordan, Congo, Ecuador and France. The Cheirolepidiaceae familt was exclusively present in the Mesozoic era. Hence, the evolution of the botanical origins of the produced resins during the Mesozoic and Cenozoic eras was discussed. It seems that Araucariaceae and Cheirolepidiaceae were the dominant resin producing trees during the Upper Jurassic and the Lower Cretaceous. While, cupressaceous resiniferous plants were dominant during the Upper Cretaceous. Howerver, resins dating from the Cenozoic era, were produced by a wider variety of plants, as resiniferous families of Angiosperm intensively participated in the resin production, i.e. the Peruvian amber produced by Fabaceae. Conifer resins traces were also detected in the Tertiary, such as the amber from the Araucariaceae found in New Zealand. The obtained data allowed a re-evaluation of the classification of ambers by Py-GC-MS, leading to the discovery of a novel molecule. This molecule of an unknown structure brings a new discrimination factor between the classes Ib and Ic. Finally, the age / maturity relationship is showed to be dependent on the burial and the conservation conditions of the resins. A broad molecular database is established based a large group of amber outcrops from different ages, and having diverse botanical origins. This database could be used as a comparative platform for further work in the future

1500 arthropodes ont été répertoriés dans les ambres médio-crétacés français. D'autres inclusions (des microorganismes) y aussi ont été trouvées. Les actinomycètes sont très diversifiés. La cyanobactérie Palaeocolteronema cenomanensis est le taxon le plus fréquent. Les eucaryotes (champignons, protistes végétaux et animaux) ont montré une diversité importante. Certains microorganismes ont été piégés sur les arbres, d'autres lors de la chute au sol de la résine ou lors de sa sécrétion par des racines. Le plus spectaculaire concerne la découverte de microfossiles marins, apportés dans la résine par une hausse du niveau marin ou par les embruns. Des liens trophiques complexes existaient dans la forêt fossile. Procaryotes, champignons et quelques arthropodes étaient saprotrophes. Amibes et ciliés étaient bactérivores. Certains acariens et coléoptères étaient fongivores. Divers diptères, hyménoptères, hétéroptères... étaient prédateurs, les chaînes trophiques étant dominées par les araignées.

De nouveaux gisements à ambre et à végétaux ont été découverts dans les terrains
albiens et cénomaniens de Charente-Maritime (France). L'un d'eux, daté de l'Albien, constitue l'un des plus anciens mais aussi l'un des plus importants gisements d'ambre fossilifère du Crétacé, compte tenu de la richesse et de la diversité des inclusions répertoriées. Les insectes et les arthropodes sont les plus nombreux, mais quelques restes de vertébrés (plume, peau de reptile) et des fragments végétaux sont également signalés. La singularité de cet ambre est d'avoir préservé une abondante faune d'arthropodes vivant au niveau de la litière du sol, alors que l'essentiel des inclusions représente généralement le biotope vivant le long du tronc ou des branches de l'arbre producteur de résine. La confrontation d'analyses taphonomiques, xylologiques et physico-chimiques permet de discuter la source botanique probable de cet ambre.
Quelques insectes particulièrement significatifs pour la compréhension de l'histoire
évolutive de leur groupe, ou bien informatifs d'un point de vue paléoenvironnemental ou paléobiogéographique, font l'objet d'une étude systématique détaillée. Des informations complémentaires, d'ordre paléoécologique et paléoclimatique, sont apportées par les nombreux végétaux associés dans les gisements sous forme de bois ou de feuilles. Une reconstitution régionale des écosystèmes terrestres côtiers médio-crétacés est proposée, via l'analyse sédimentologique des milieux de dépôt et les informations paléoécologiques fournies par ces assemblages fossiles. Ces gisements contribuent à une meilleure connaissance des biotopes côtiers du Crétacé, période cruciale pendant laquelle la co-évolution des insectes et des plantes à fleurs a constitué les prémices de nos écosystèmes actuels.

Abstract:
AbstractAldène Cave is a system of 9 km of extent, on four hydrogeological levels. Within the first two fossil levels, which comprise more than half of the system, many archaeological remains have been discovered. They represent a continuum of more than 350,000 years of human history. On the second level, we find the Paul Ambert gallery, discovered in 1948 by the Abbé Dominique Cathala. This gallery contains many human traces, with footprints and marks of torches that were brought into the cave. A recent geomorphological study of these elements concerned registration and systematic analysis of the lighting marks, as well as an initial determination of the footprints. This work confirmed the contemporaneousness and functional link of these archaeological remains. Lighting management could be determined precisely with the traces on the walls and the remains discovered on the floor in connection with the footprints. These data, investigated with a spatial approach in relation to the cave network, clarify the prehistoric passages and allow an interpretation of the behaviour of visitors. All elements together form the picture of a family at a speleological investigation, which is attributed to the Mesolithic.

Abstract:
Abstract Until 1984 (Higuchi and Wilson 1984), the isolation and characterization of fossil DNA was considered unattainable, as the methodologies for extracting minute quantities of partially degraded DNA and their subsequent enzymic amplification were not available. With the advent of the polymerase chain reaction (PCR) (Mullis et al.1986), a new analytical tool became available for the molecular study of fossils. It is now possible to conduct molecular studies of extinct organisms or fossils, utilizing their DNA to unravel biological and evolutionary questions. The value of fossil evidence is that it may demonstrate the condition of taxa before evolutionary divergence obscured phylogenetic relationships. Because they are older, ancient fossil DNA sequences should be less divergent than extant sequences and should therefore have value for relating more derived extant taxa. When compared with extant DNA, ancient DNA sequences may also provide an insight into the pattern of molecular evolutionary change through time. In this light, ancient DNA could provide invaluable information on the evolution and epidemiology of infectious diseases. Understanding the evolution of virulence and the acquisition of virulence factors by microbial populations could help in identifying microorganisms that are likely to become ‘emerging’ pathogens, as well as in creating methods to arrest the development of pathogenic potential for those organisms.

Abstract:
Abstract When I was a young boy, my grandfather took me for long walks on the beach. Among the pebbles at the edge of the ocean were many fossils, including thunderstones. These are fossils of extinct animals in the squid family that lived in the Jurassic and Cretaceous periods. They can be difficult to discern among the pebbles, so it requires training and concentration to find them. They are sufficiently common along Danish beaches so that, unlike the less common amber, they hold no monetary value. Nevertheless, I desired them for their long semitransparent golden shape and for the pleasure of the hunt. My grandfather was an expert in finding thunderstones and one of my greatest ambitions was to become as skilled. Learning is commonly associated with lessons and class- rooms. But Oscar Wilde was right to point out that nothing that is worth knowing can be taught. Collecting thunder- stones is not a subject in any school I know of. To learn it, I needed only plenty of time and motivation, which are some of the most important elements for learning. Other ones include a certain amount of talent and a good portion of luck. Desire and pleasure are central for learning. They are involved in the possible causes for poor mathematical abilities, stuttering, and dyslexia.

Abstract:
This paper is concerned with making 3D scans of semitransparent ambers with and without inclusions. The paperpresents results of using a variety of devices applied for this purpose. Equipment used in the experiments includesa 3D laser scanner, a structured light scanner, a stereo camera, a camera array and a tomograph. The main objectused in the experiment was an amber with a fossil of a lizard. The paper shows possibilities of acquiring the 3Dstructure of fossils embedded in semitransparent material which interfere with the measurement performed by 3Dscanning equipment. Moreover, the paper shows the application of results of 3D scanning as the 3D scan of alizard was reconstructed in a virtual reality cave making it possible to visualize in detail its shape and texture.
