Geophysical evidence strongly supports the complete isolation of India and Madagascar (Indo-Madagascar) by ∼100 million years ago, though sparse terrestrial fossil records from these regions prior to ∼70 million years ago have limited insights into their biogeographic history during the Cretaceous. A new theropod dinosaur, Dahalokely tokana, from Turonian-aged (∼90 million years old) strata of ...

A suite of outcrop samples from the Cauvery Basin belonging to mudrock-claystone dominated Karai Formation were analysed for nannofossil biostratigraphy in two newly measured sections at and Garudamangalam. The age Section is interpreted as early Albian Turonian, whereas Garudamangalam late Cenomanian. ‘BC’ zones Bown et al. (1998) are applicable both sections, Cenomanian Turonian ‘UC’ Burnett ...

The best-documented example of rapid climate change that characterized the so-called 'greenhouse world' took place at the time of the Palaeocene-Eocene boundary: introduction of isotopically light carbon into the ocean-atmosphere system, accompanied by global warming of 5-8 degrees C across a range of latitudes, took place over a few thousand years. Dissociation, release and oxidation of gas hy...

Abderaz Formation is one of the Upper Cretaceous formations in the Kopet-Dagh sedimentary basin. A stratigraphic section from the mentioned formation is selected for detailed systematic description with regard to echinoids. Numerous well preserved representatives of the families Mircrasteridae wright, 1857 and Echinocorythidae Lambert, 1920 are described from the Ghaleh-Zoo stratigraphic sectio...

The mesoeucrocodylian record from the Bauru Group (Paraná Basin, Brazil) comes three formations: Adamantina (Late Turonian–Early Maastrichtian), Presidente Prudente (Early Campanian–Early Maastrichtian) and Marília (Maastrichtian). These records are restricted to Early Coniacian–Early Maastrichtian. Here, we report a new crocodyliform Group, which was first of Araçatuba Formation, locality Coro...

The trace fossil Lepidenteron lewesiensis (Mantell 1822) provides an exceptional taphonomic window to diversity of fishes as shown for the Upper Cretaceous of Poland, in the Middle Turonian-Lower Maastrichtian deposits of the Opole Trough, Miechów Trough, Mazury-Podlasie Homocline, and SE part of the Border Synclinorium. Lepidenteron lewesiensis is an unbranched burrow lined with small fish sca...

The extinct representatives of family are known from the Upper Cretaceous (the Turonian: Pseudocuphosis tristis Nikitsky, 2002 and Archaeserropalpus cretaceus Nikitsky, 2002; the Cognac-Santonian: Archaeoxylita zherichini Nikitsky, 1977). Melandryid beetles are also known from Eocene ambers of Europe. One species was described from Ukrainian amber (Orchesia rasnitzyni Nikitsky, 2011). At least ...

A dentary fragment containing the last two molars (m2-3) from the Late Cretaceous (Santonian-?Campanian) Bostobe Formation exposed at the locality of Shakh Shakh, northeast Aral Sea region, Kazakhstan, is attributed to a new taxon of Zhelestidae, Zhalmouzia bazhanovi, gen. et sp. nov. This specimen is only the second mammal described from Shakh Shakh, the unidentifiable eutherian Beleutinus orl...
