The ankle joint of Pterodaustro guinazui [PDF]

Acta Palaeontologica Polonica
The hindlimb of pterosaurs has been much less studied than the pterosaur wing. However, it is relevant to understand the evolution, phylogeny and ecology of these animals.

Variable preservation potential and richness in the fossil record of vertebrates

Palaeontology, Volume 63, Issue 2, Page 313-329, March 2020., 2020
Abstract Variation in preservation and sampling probability clouds our estimates of past biodiversity. The most extreme examples are Lagerstätten faunas and floras. Although such deposits provide a wealth of information and represent true richness better than other deposits, they can create misleading diversity peaks because of their species richness ...

Sinomacrops bondei, a new anurognathid pterosaur from the Jurassic of China and comments on the group [PDF]

PeerJ, 2021
Anurognathids are an elusive group of diminutive, potentially arboreal pterosaurs. Even though their monophyly has been well-supported, their intrarelationships have been obscure, and their phylogenetic placement even more.

Development and evolution of the notarium in Pterosauria

Journal of Anatomy, 2020
The notarium is the structure formed by fusion of the dorsal vertebrae which occurred independently in pterosaurs and birds. This ankylosis usually involves two to six elements and in many cases, also includes the last cervical vertebra. Fusion can occur

On the validity of the genus Amblydectes Hooley 1914 (Pterodactyloidea, Anhangueridae) and the presence of Tropeognathinae in the Cambridge Greensand

Anais da Academia Brasileira de Ciências, 2021
Amblydectes is a problematic genus proposed more than a century ago for several pterosaur specimens from the Cambridge Greensand. Its problematic nature is due to the fragmentary preservation of the referred specimens, limited to several rostral tips. In
