Abstract Herein, Ryazanian (Berriasian) macrofossils from three well cores in the Central Graben (wells B18-02, L06-02, The Netherlands) and on Jæren High (well 7/7-2, Norway) southern North Sea region are described. Macrofossils mainly represented by buchiid bivalves ( Buchia volgensis ) ammonites Surites , Lynnia Praetollia ?). genus is recorded for first time outside its topotypical area, sy...

We describe a new semionotiform fish, Tlayuamichin itztli gen. et sp. nov. from the Early Cretaceous (Albian) of Mexico, which constitutes one of the youngest semionotid articulated remains. The new taxon is represented by five well-preserved specimens from the Tlayúa Quarry near Tepexi de Rodríguez in Puebla State, central Mexico. A series of paraethmoid bones anterior to the supraorbital seri...

The first flowering plant fossils occur as rare, undiverse pollen grains in the Early Cretaceous (Valanginian-Hauterivian). Angiosperms diversified slowly during the Barremian-Aptian but rapidly during the Albian-Cenomanian. By the end of the Cretaceous, at least half of the living angiosperm orders were present, and angiosperms were greater than 70% of terrestrial plant species globally. The r...
