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.

Bioestratigrafía de los materiales plio-cuaternarios del borde norte de la depresión de Granada

Estudios Geologicos, 1990
Se describen cuatro nuevos yacimientos de vertebrados en los materiales continentales de la Depresión de Granada. Las dataciones obtenidas permiten introducir unos jalones de edad en los mismos, de los que hasta ahora no se disponían.

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.

Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

The Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

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”.

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

The Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.
