Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

Anatomy and variation in the paraphyletic Mosasaurus lemonnieri assemblage from the Craie phosphatée de ciply, Belgium

open access: yesThe Anatomical Record, EarlyView.
Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

Osteohistological evidence for terrestrial adaptation and an extended growth period in mekosuchine crocodylians and its potential role in their extinction

open access: yesThe Anatomical Record, EarlyView.
Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.
