A late Paleocene probable metatherian (?deltatheroidan) survivor of the Cretaceous mass extinction
Deltatheroidans are primitive metatherian mammals (relatives of marsupials), previously thought to have become extinct during the Cretaceous mass extinction. Here, we report a tiny new deltatheroidan mammal (Gurbanodelta kara gen. et sp. nov.) discovered at the South Gobi locality in China (Xinjiang Province) that is the first Cenozoic record of this clade and renders Deltatheroida a Lazarus ta...
متن کاملIntraoceanic subduction spanned the Pacific in the Late Cretaceous–Paleocene
The notorious ~60° bend separating the Hawaiian and Emperor chains marked a prominent change in the motion of the Pacific plate at ~47 Ma (million years ago), but the origin of that change remains an outstanding controversy that bears on the nature of major plate reorganizations. Lesser known but equally significant is a conundrum posed by the pre-bend (~80 to 47 Ma) motion of the Pacific plate...
متن کاملEarly Paleocene landbird supports rapid phylogenetic and morphological diversification of crown birds after the K-Pg mass extinction.
Evidence is accumulating for a rapid diversification of birds following the K-Pg extinction. Recent molecular divergence dating studies suggest that birds radiated explosively during the first few million years of the Paleocene; however, fossils from this interval remain poorly represented, hindering our understanding of morphological and ecological specialization in early neoavian birds. Here ...
متن کاملCretaceous-paleocene terrestrial faunas of India: lack of endemism during drifting of the Indian plate.
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...
متن کاملThe Cretaceous and Paleocene Pleurotomariid (gastropoda: Vetigastropoda) Fauna of Seymour Island, Antarctica
Leptomaria antipodensis and Leptomaria hickmanae are described from the Upper Cretaceous [Maastrichtian] Lopez de Bertodano Formation, Seymour Island, and represent the first Mesozoic records of the family Pleurotomariidae from Antarctica. Leptomaria stillwelli, L. seymourensis, Conotomaria sobralensis and C. bayeri, from the Paleocene [Danian], Sobral Formation, Seymour Island, are described a...
