Early Cretaceous vertebrate assemblages from East Asia and particularly the Jehol Biota of northeastern China flourished during a period of highly debated climatic history. While the unique characters of these continental faunas have been the subject of various speculations about their biogeographic history, little attention has been paid to their possible climatic causes. Here we address this ...

Disarticulated and incomplete remains from a new diminutive ornithopod are described. They come from the Cameros Basin in the north of Spain and were collected from the red clays of the Castrillo de la Reina Formation, ranging from Upper Barremian to Lower Aptian. The new ornithopod described here is slender and one of the smallest ever reported. An up-to-date phylogenetic analysis recovers thi...

BACKGROUND The Yellow Cat Member of the Cedar Mountain Formation (Early Cretaceous, Barremian?) of Utah has yielded a rich dinosaur fauna, including the basal therizinosauroid theropod Falcarius utahensis at its base. Recent excavation uncovered a new possible therizinosauroid taxon from a higher stratigraphic level in the Cedar Mountain Formation than F. utahensis. METHODOLOGY/PRINCIPAL FIND...

Two excellently preserved small strobili were obtained from a Wealden plant debris bed in the Lower Cretaceous (Barremian) Wessex Formation, south-east of Chilton Chine, on Isle Wight, southern England. The are as compressions and show characteristic morphology sporangiophore heads Equisetales. Based strobili, attribution to certain species is not warranted. Therefore, have been left unassigned...

Early Cretaceous (late Barremian – early Aptian) fissure fill deposits near Balve, North Rhine Westphalia, Germany, have yielded a rich continental vertebrate fauna over the course of last two decades. More than 250 fragmentary specimens, including more 150 osteoderms (i.e., granicones), represent late helochelydrid Helochelydra nopcsai , which had previously been reported from UK, France, and ...

Abstract The breakup of Gondwana resulted in sedimentary deposits recording lacustrine to marine environmental transitions the South Atlantic rift basins during Early Cretaceous. Currently, ambiguity pervades our understanding timing and orientation initial seawater incursion. Here we investigated hydrocarbon biomarkers sediments from two drill cores off West Africa with stratigraphic coverage ...
