An Early Cretaceous labyrinthodont
Alcheringa: An Australasian Journal of Palaeontology, 1991A crescentic intercentrum and isolated skull bone have been recovered from Early Cretaceous rift valley sediments of the Gippsland Basin, southeastern Victoria. The intercentrum, which is unquestionably from a temnospondyl labyrinthodont, and an ornamented cranial bone confirm the earlier identification of a mandible from a nearby locality as ...

Journal of the Geological Society, 1993
A one day meeting of the British Sedimentological Research Group (BSRG), convened by K. G. Taylor and A. H. Ruffell, was held at the Postgraduate Research Institute for Sedimentology, University of Reading on 23 June 1992. The meeting set out to consider what is known about palaeoenvironments of the NW European early Cretaceous and to ...

A eudicot from the Early Cretaceous of China
Nature, 2011The current molecular systematics of angiosperms recognizes the basal angiosperms and five major angiosperm lineages: the Chloranthaceae, the magnoliids, the monocots, Ceratophyllum and the eudicots, which consist of the basal eudicots and the core eudicots. The eudicots form the majority of the angiosperms in the world today.

An Early Cretaceous fruit with affinities to Ceratophyllaceae
American Journal of Botany, 2009A new genus and species with affinities to Ceratophyllaceae from the Lower Cretaceous of Kansas, USA is reported. The fruits of Donlesia dakotensis gen. et sp. nov. are smooth achenes with two winged lateral spines, two winged facial spines, one stylar spine, and a long peduncle with a distinctive groove. The facial spines are arranged perpendicular to

Mammalian hairs in Early Cretaceous amber
Naturwissenschaften, 2010Two mammalian hairs have been found in association with an empty puparium in a approximately 100-million-year-old amber (Early Cretaceous) from France. Although hair is known to be an ancestral, ubiquitous feature in the crown Mammalia, the structure of Mesozoic hair has never been described.

Early Cretaceous Dinosaurs from the Sahara
Science, 1994A major question in Mesozoic biogeography is how the land-based dinosaurian radiation responded to fragmentation of Pangaea. A rich fossil record has been uncovered on northern continents that spans the Cretaceous, when continental isolation reached its peak. In contrast, dinosaur remains on southern continents are scarce.

True Polar Wander since the Early Cretaceous
Science, 1975The motions of the lithospheric plates have been reconstructed for three time intervals back to the Early Cretaceous. These displacements were analyzed to determine the best-fitting rigid rotation, which could then be ascribed to true polar wander. The true polar wander so obtained is no larger than a few degrees and is within the magnitude of the ...

The Cretaceous Layers Later than the Early Cretaceous
2018The marine continuity after the Early Cretaceous implies an essential difference with the condition in the orogenic belt with a N-S trend of the Patagonian Cordillera, and it could be said, in a figurative sense, that the continent has kept its feet in the ocean.

A basal troodontid from the Early Cretaceous of China
Nature, 2002Troodontid dinosaurs form one of the most avian-like dinosaur groups. Their phylogenetic position is hotly debated, and they have been allied with almost all principal coelurosaurian lineages. Here we report a basal troodontid dinosaur, Sinovenator changii gen. et sp. nov., from the lower Yixian Formation of China.
