Abstract:

A general characterization of the Late Cretaceous floras of the Zeya-Bureya Basin is provided based on floristic assemblages from Russia (Amur Region) and China (Heilongjiang Province). Four phases of floral evolution were revealed: the Turonian-Coniacian (the Sutara flora), the Santonian (the Yong’ancun and Middle Kundur floras), the Campanian (the Taipinglinchang and Late Kundur floras) and the late Maastrichtian (Bureya flora). This long paleofloral succession provides possibility for investigation of different trends in the evolution of the Late Cretaceous taxa, flora, and climate.

Abstract:

Earth’s terrestrial ecosystem during the early Cretaceous was marked by the dominance of naked seeded plants and appearance of flowering plants. Tectonic changes and evolutionary processes affected southern floras of the globe during this time. Review of Indian early Cretaceous flora distributed in peri and intra–cratonic basins signify homogenity of composition with regional variations. The flora composed of pteridophytes, pteridospermaleans, pentoxylaleans, bennettitaleans, ginkgoaleans, coniferaleans, taxaleans and taxa of uncertain affinity along with sporadic occurrence of flowering plant

Abstract:

Through a comprehensive analytical study of the Mesozoic flora and synthesis of the available data 12 assemblage zones and a floral succession are established. These assemblage zones also extend into the Early Cretaceous flora in the neighboring countries: Pakistan, Nepal, Bhutan and Sri Lanka. The Gondwana Triassic elements and the European Jurassic-Cretaceous elements in the flora are highlighted. The inter-relationship of the Mesozoic floras of Gondwanaland, European and Asian countries is examined. The relative age of the biozones is worked out on the basis of plant megafossils, palynology

Abstract:

The replacement of mesophytic flora, with a predominance of gymnosperms and ferns, by cainophytic flora, with a prevalence of angiosperms, took place in the middle of the Cretaceous Period. The investigation of this phenomenon is of great importance to the understanding of evolution patterns of the major systematic groups, and palaeofloras as a whole. The processes whereby angiosperms appeared and diversified, as well as the processes whereby gymnosperms and ferns met extinction, appear to have different features, depending on the region studied.

Angiosperm remains dominate the fossil assemblage both in terms of taxonomic diversity and quantitatively, with about 65 different species based on about 1,000 specimens of flowers, fruits and seeds. There are surprisingly few nonangiosperm species in the flora, with only four specimens assigned to bryophytes, ferns and conifers. There are no megaspores of Selaginellales or Salviniales, which are otherwise common in many Cretaceous mesofossil floras. Among angiosperms,

For most of the Twentieth Century the angiosperm archetypal flower has been viewed as relatively large, multiparted, with spirally arranged fleshy appendages, and as being probably beetle pollinated as in some extant Magnoliales. However, the preponderance of fossil evidence indicates that flowers with such characters do not appear until the mid-Cretaceous, well after smaller simpler fossil flowers such as platanoids and chloranthoids. Winteraceous and Chloranthaceous pollen appears more or less simultaneously in the Lower Cretaceous, but rapidly mounting evidence for mosaicism in Cretaceous t

Abstract:

The analysis of the distribution of plant remains in deposits of the Aigur and Toptan formations (Omsukchan district of the Magadan Region) showed that the main part of the species that were included in the Toptan stratoflora (Samylina, 1976), in fact come from the Aigur Formation. Floristic assemblages of the Aigur and Toptan formations are very similar in systematic composition. Increasing the diversity of flowering plants and reduction of typical Cretaceous taxa (cycadophytes and Ginkgoales was not indicated on the boundary between these formation. Thus, there is no evidence of significant

Abstract:

In India the earliest angiospermous plants are known in the form of pollen/fruit or ?flower from the Lower Cretaceous (Aptian) of Rajmahal flora. Unfortunately, the Lower and Middle Cretaceous records of angiosperms from India are very poor as compared to those in other continents. The definite records of angiosperms started appearing from the Lameta flora considered as Maastrichtian in age. During the Upper Maastrichtian-Danian they became the most dominant element of the flora. An influx of Southeast Asian elements could only be noticed in the beginning of the Neogene.

Conifers and cycadophytes are dominant: pteridophytes and pteridosperms are poorly represented. Early Cretaceous age is supported for the Gollapalle flora.

Hydrothermal palaeoenvironments are very uncommon in Upper Jurassic and Lower Cretaceous deposits worldwide.

A total of 136 plant specimens and three insect wings were collected and studied. This entomofauna consists of dragonfly (Odonata) wings including Cymatophlebiidae and an undetermined new genus and species of Aktassiidae, representing the first report of these families for the Iberian Peninsula.

Abstract:

A taxonomic study of Albian ferns from the Partizansk Coal Basin of Primorsky Krai was carried out. The Albian Age was an important stratigraphic milestone, when the Early Cretaceous flora changed to the Late Cretaceous flora. It was revealed that typical Mesozoic Onychiopsis predominated in taphocenoses, and representatives of young and evolutionarily advanced taxa Asplenium, Birisia appeared. The taxonomic composition of ferns in the Albian taphocenoses was almost constant from north to south. The vegetation of the Partizansk Basin occupied the coastal plain during Albian time, which was con

However, megafloras used to develop this hypothesis are from the Northern Great Plains (NGP) of North America, and relatively little is known about floras from southern basins. Here, we present a quantitative analysis of an earliest Paleocene megaflora (<350 kyr after K/Pg boundary) from the Ojo Alamo Sandstone in the San Juan Basin (SJB), New Mexico.

AbstractAngiosperms first appeared in the fossil record as pollen during the Valanginian–Hauterivian; they spread out of the tropics in the Aptian and Albian, and radiated in the Late Cretaceous. Despite these general patterns, details of the taxonomic, geographic, and ecological evolution of Cretaceous angiosperms are relatively poorly known because only a handful of Early and mid-Cretaceous macrofloras have been reported. This is the first detailed report of a fossil leaf flora from the Cedar Mountain Formation from the mid-Cretaceous of the Western Interior. We describe a flora that is over
