Braincase anatomy and palaeoneurology of Venetoraptor gassenae, a lagerpetid pterosauromorph from the Late Triassic of southern Brazil

Palaeontology, Volume 69, Issue 2, 2026.
Abstract There is a growing consensus that pterosaurs and the flightless Lagerpetidae are closely related. This relationship is supported by apomorphies throughout the skeleton, including endocranial character states such as a well‐developed floccular fossa and a tall anterior semicircular canal. Our knowledge of lagerpetid anatomy has been improved by

THE PRESENCE OF AN ORBITOANTORBITAL FENESTRA: FURTHER EVIDENCE OF THE ANUROGNATHID PECULIARITY WITHIN THE PTEROSAURIA

RIVISTA ITALIANA DI PALEONTOLOGIA E STRATIGRAFIA, 2022
The anurognathids are peculiar pterosaurs characterized by broad skulls with very short rostra and broadly arched jaws. The presence of distinct or confluent external naris and antorbital fenestra in these pterosaurs has been debated in the last years.

The shape, structure, function, and evolution of the pterosaurian uropatagium [PDF]

Anais da Academia Brasileira de Ciências
The wing membrane of pterosaurs is the earliest innovation in the evolution of vertebrate powered flight and led to pterosaurs dominating the Mesozoic skies.

Pterodactyloid pterosaur bones from Cretaceous deposits of the Antarctic Peninsula [PDF]

Anais da Academia Brasileira de Ciências, 2019
Fossil vertebrates from Antarctica are considerably rare, hampering our understanding of the evolutionary history of the biota from that continent. For several austral summers, the PALEOANTAR project has been carrying out fieldwork in the Antarctic ...

The first pterosaur from the Bauru Group: an azhdarchid from the Upper Cretaceous of Brazil

Papers in Palaeontology, Volume 11, Issue 5, September/October 2025.
Abstract The vertebrate fossil record of the Bauru Group (Upper Cretaceous, southeastern Brazil) is remarkably rich, with a predominance of titanosaurs and crocodyliforms, alongside theropods, turtles, squamates, fishes and even small mammals. In contrast, pterosaur remains from the Bauru Group have remained elusive until now.

Cautionary tales on the use of proxies to estimate body size and form of extinct animals

Ecology and Evolution, Volume 14, Issue 9, September 2024.
Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

Athletic capability index in pterosaurs: an initial assessment [PDF]

Anais da Academia Brasileira de Ciências
Pterosaurs had a unique morphology among flying vertebrates, and therefore, a direct comparison with living vertebrates regarding their terrestrial locomotion is impossible.

The largest flying reptile from Gondwana: a new specimen of Tropeognathus cf. T. mesembrinusWellnhofer, 1987 (Pterodactyloidea, Anhangueridae) and other large pterosaurs from the Romualdo Formation, Lower Cretaceous, Brazil

Anais da Academia Brasileira de Ciências, 2013
A very large pterosaur (MN 6594-V) from the Romualdo Formation (Aptian/Albian), Santana Group, Araripe Basin, is described. The specimen is referred to Tropeognathus cf. T.

A new cockroach (Blattodea, Rhipidoblattinidae) from the Toarcian (Lower Jurassic) of Alderton Hill, Gloucestershire, UK, and the earliest likely occurrence of aposematic colouration in cockroaches

Papers in Palaeontology, Volume 10, Issue 5, September/October 2024.
Abstract We describe the seventh valid species of cockroach, Alderblattina simmsi gen. et sp. nov., from insect‐rich strata recording the Toarcian Oceanic Anoxic Event (T‐OAE). The T‐OAE represents a period of extreme global warming and environmental change that drove palaeoecological pressures and evolutionary changes in marine and terrestrial ...
