Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

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

The 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)

The 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.

Osteology of the pectoral girdle and forelimb of Siriusgnathus niemeyerorum, a Late Triassic traversodontid cynodont from Brazil

The Anatomical Record, EarlyView.
Abstract Traversodontids are non‐mammaliaform cynodonts, herbivorous to omnivorous, that lived during the Triassic. In the Late Triassic, some members of this group increased in body size relative to other cynodont lineages and evolved postcranial adaptations associated with locomotion.

The lower deciduous dentition of protodidelphids (Mammalia, Marsupialia) from the Itaboraí Basin (lower Eocene), Brazil, and the validity of “Riolestes capricornicus” (Goin et al., 2009)

The Anatomical Record, EarlyView.
Abstract The Itaboraí Basin, Southeastern Brazil, preserved one of the most diverse mammalian faunas from the Paleogene, with Metatheria comprising more than 60% of its diversity. Among identified metatherian clades, it has been argued that Paucituberculata is represented by “Riolestes capricornicus”.

A new occurrence of tetrapod footprints from the Late Triassic of the Candelária Sequence, Brazil

The Anatomical Record, EarlyView.
Abstract The Hyperodapedon Assemblage Zone of the Candelária Sequence (Santa Maria Supersequence, Paraná Basin) preserves one of the most significant Late Triassic continental vertebrate assemblages in southern Brazil. Despite the relatively well‐documented body fossil record from this interval, ichnological records remain comparatively scarce.
