Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

New fossil unveils the dentary anatomy of the rare lepidosauromorph Cargninia enigmatica from the Upper Triassic of Southern Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Nowadays, Lepidosauria is a diverse group represented by squamates and the rhynchocephalian tuatara. However, their origins date back to the end of the Permian Period, when the stem lineages Lepidosauromorpha and Archosauromorpha diverged. Within the lepidosauromorph stem lineage, a few species have been described with unstable phylogenetic ...
