A large Megaraptoridae (Theropoda: Coelurosauria) from Upper Cretaceous (Maastrichtian) of Patagonia, Argentina

Scientific Reports, 2022
Megaraptora is a theropod clade known from former Gondwana landmasses and Asia. Most members of the clade are known from the Early to Late Cretaceous (Barremian–Santonian), with Maastrichtian megaraptorans known only from isolated and poorly informative ...

Paleopathology of a putative colossosaurian caudal vertebra (Neosauropoda: Titanosauria) from the Presidente Prudente Formation, Brazil

The Anatomical Record, EarlyView.
Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

The Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

A new meiolaniform turtle from the Maastrichtian of Northern Patagonia, Argentina

Acta Palaeontologica Polonica
Meiolaniformes are a group of chelonians including the famous horned-turtles Niolamia argentina (Patagonia) and Meiolania platyceps (Australia). In South America, the Late Cretaceous meiolaniforms are represented by two named taxa: Patagoniaemys ...

Late Cretaceous (late Campanian–Maastrichtian) sea-surface temperature record of the Boreal Chalk Sea [PDF]

Climate of the Past, 2016
The last 8 Myr of the Cretaceous greenhouse interval were characterized by a progressive global cooling with superimposed cool/warm fluctuations. The mechanisms responsible for these climatic fluctuations remain a source of debate that can only be ...
