LIMITED CONVERGENCE IN THE POSTCRANIUM OF AQUATIC CROCODYLOMORPHA [PDF]

open access: yes, 2023
peer reviewedABSTRACT. Thalattosuchia (Early Jurassic–Early Cretaceous) and Dyrosauridea (Late Cretaceous–Early Eocene) are crocodylomorph archosaurs which diversified in fluvial and marine environments and endured extinction events (i.e.

Evaluation of the endocranial anatomy of the early Paleogene north African gavialoid crocodylian Argochampsa krebsi and evolutionary implications for adaptation to salinity tolerance in marine crocodyliforms. [PDF]

open access: yesJ Anat
Abstract Argochampsa krebsi is a gavialoid crocodylian from the early Paleogene of North Africa. Based on its recovered phylogenetic relationship with South American species, it has been inferred to have been capable of transoceanic dispersal, but potential anatomical correlates for a marine lifestyle have yet to be identified.

Evaluating growth in Macrospondylus bollensis (Crocodylomorpha, Teleosauroidea) in the Toarcian Posidonia Shale, Germany

open access: yesPapers in Palaeontology, Volume 9, Issue 5, September/October 2023., 2023
Abstract The study of how organisms grow is a fundamental aspect of palaeontology. Growth in teleosauroids is poorly understood and little studied, especially in an ontogenetic sense. We investigate growth rates of the most common and abundant teleosauroid, Macrospondylus bollensis, in which a large sample of multiple body sizes is available from the ...

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha. [PDF]

open access: yesJ Anat
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

Ontogenetic variability of the intertympanic sinus distinguishes lineages within Crocodylia

open access: yesJournal of Anatomy, Volume 242, Issue 6, Page 1096-1123, June 2023., 2023
We recognised the usefulness of the paratympanic sinuses in distinguishing major lineages within Crocodylia. 3D geometric morphometric approaches allow us to quantify the ontogeny and variability of the intertympanic sinus within one of the largest dataset of modern species, including one of the largest specimens ever scanned at such a high resolution.

Detailed braincase anatomical description and neuroanatomical study of Portugalosuchus azenhae, from the Cenomanian (Late Cretaceous) of Portugal. Abstract We present the first detailed braincase anatomical description and neuroanatomical study of Portugalosuchus azenhae, from the Cenomanian (Late Cretaceous) of Portugal.

The locomotor ecomorphology of Mesozoic marine reptiles

open access: yesPalaeontology, Volume 66, Issue 2, March/April 2023., 2023
Abstract The aftermath of the end‐Permian mass extinction provided ecological opportunities for many groups of reptiles, marking the beginning of reptile dominance of the Mesozoic oceans. Clades such as ichthyosaurs, thalattosuchians, sauropterygians, mosasaurs and turtles evolved a remarkable diversity of ecological niches and became important ...

Taxonomic and stratigraphic update of the material historically attributed to Megalosaurus from Portugal [PDF]

open access: yesActa Palaeontologica Polonica
The first paleontological works on Mesozoic vertebrates from Portugal, carried out from the end of the 19th and the first half of the 20th century, provided the discovery of significant collections of vertebrate fossils.
