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 ...

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 ...

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.

A Review of the Taxonomy and Palaeoecology of the Anurognathidae (Reptilia, Pterosauria)

Acta Geologica Sinica - English Edition, 2020
The anurognathids are an enigmatic and distinctive clade of small, non‐pterodactyloid pterosaurs with an unusual combination of anatomical traits in the head, neck, wings and tail.

Do cladistic and morphometric data capture common patterns of morphological disparity? [PDF]

, 2015
The distinctly non-random diversity of organismal form manifests itself in discrete clusters of taxa that share a common body plan. As a result, analyses of disparity require a scalable comparative framework.

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.

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.

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 ...
