Mammalian hairs in Early Cretaceous amber

Naturwissenschaften, 2010
Two 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, 1994
A 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.

Early Cretaceous cementing pectinid bivalves

Cretaceous Research, 1996
Abstract Large thick-shelled cementing pectinids, variously described asProhinnites, are conspicuous, if not abundant, epifaunal bivalves in shallow marine facies deposited in a range of Tethyan and Southern Temperate locations during the Early Cretaceous.

Purbeck–Wealden (early Cretaceous) climates

Proceedings of the Geologists' Association, 1998
A multidisciplinary colligation including new data and analysis of the evidence for the climates of southern Britain during c. 140 Ma. to c. 120 Ma BP (Berriasian-Barremian — ? earliest Aptian). The climate was at first hot, semi-arid and ‘Mediterranean’ (rather than ‘monsoonal’) in type, probably with seasonally opposed winds (E/W).

True Polar Wander since the Early Cretaceous

Science, 1975
The 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 ...

Early Cretaceous Spider Web with Its Prey

Science, 2006
Araneoid spiders are renowned for their efficient capture of flying insects with intricate aerial webs. Origins of this web structure are obscure, however, because they rarely fossilize. Reported here is an exceptional situation of insects trapped in part of a gummy aerial web preserved in a runnel of amber from Spain that is ~110 million years old ...

The Cretaceous Layers Later than the Early Cretaceous

2018
The 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.
