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 ...

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 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

I believe I can fly… New implications for the mode of life and palaeoecology of the Late Triassic Ozimek volans based on its unique long bone histology

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.

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.

Discovery of a rare arboreal forest-dwelling flying reptile (Pterosauria, Pterodactyloidea) from China [PDF]

Proceedings of the National Academy of Sciences, 2008
A previously undescribed toothless flying reptile from northeastern China, Nemicolopterus crypticus gen. et sp. nov., was discovered in the lacustrine sediments of the Early Cretaceous Jiufotang Formation, western Liaoning, China.

Braincase and neuroanatomy of the lagerpetid Dromomeron gregorii (Archosauria, Pterosauromorpha) with comments on the early evolution of the braincase and associated soft tissues in Avemetatarsalia

The Anatomical Record, Volume 307, Issue 4, Page 1147-1174, April 2024.
Abstract The anatomy of the braincase and associated soft tissues of the lagerpetid Dromomeron gregorii (Archosauria: Avemetatarsalia) from the Late Triassic of the United States is here described. This corresponds to the first detailed description of cranial materials of Lagerpetidae, an enigmatic group of Late Triassic (c.

Premaxillary crest variation within the Wukongopteridae (Reptilia, Pterosauria) and comments on cranial structures in pterosaurs

Anais da Academia Brasileira de Ciências
Cranial 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 ...

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.
