Recent paleontological investigations of six sections fringing the Deccan volcanic outcrops of the Indian peninsula indicate that terrestrial faunas during the Cretaceous-Paleocene transition lacked the endemism predicted by geophysical models of an oceanically isolated Indian subcontinent. At the generic and familial level there is a close correspondence between the Cretaceous vertebrates of p...

Palaeophytocrene piggae sp. nov., from the late Paleocene of western North America...

The Paleocene-Eocene Thermal Maximum (PETM) is associated with major extinctions in the deep ocean, and significant paleogeographic ecological changes surface ocean terrestrial environments. However, impact of environmental change on shelf biota less well understood. Here, we present a new PETM record low paleolatitude shallow-marine carbonate platform from Meghalaya, NE India (eastern Tethys)....
