The Late Jurassic pterosaurs from northern Patagonia, Argentina [PDF]
, 2013 Records of flying Jurassic reptiles are very scarce in the Southern Hemisphere. Upper Jurassic pterosaurs have been discovered in marine Tithonian sediments of the Vaca Muerta Formation, in the Neuquén Basin, Patagonia, Argentina. Only four specimens are

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 ...

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 ...

Were early pterosaurs inept terrestrial locomotors? [PDF]
, 2015 Pterodactyloid pterosaurs are widely interpreted as terrestrially competent, erect-limbed quadrupeds, but the terrestrial capabilities of non-pterodactyloids are largely thought to have been poor.

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 ...

Palaeontology, Volume 67, Issue 3, May/June 2024.Abstract The small diapsid reptile Ozimek volans is one of the most enigmatic representatives of the Late Triassic fauna of Krasiejów, Poland. Phylogenetically, Ozimek was identified as a ‘protorosaurian’ related to tanystropheids, but the extremely elongated limbs and presumed gliding abilities are unusual for this group.

Anais da Academia Brasileira de CiênciasCranial crests show considerable variation within the Pterosauria, a group of flying reptiles that developed powered flight. This includes the Wukongopteridae, a clade of non-pterodactyloids, where the presence or absence of such head structures, allied ...
