Morphology forms the most fundamental level of data in vertebrate palaeontology because it
is through interpretations of morphology that taxa are identified, creating the basis for broad …

Pneumatic (air‐filled) postcranial bones are unique to birds among extant tetrapods.
Unambiguous skeletal correlates of postcranial pneumaticity first appeared in the Late …

ABSTRACT Recent fieldwork in Upper Cretaceous terrestrial deposits in northwestern
Madagascar has yielded a remarkable diversity of vertebrates, including several specimens …

We present a new medium-sized basal sauropodomorph, S efapanosaurus zastronensis
gen. et sp. nov., from the Upper Triassic− Lower Jurassic Elliot Formation of South Africa. It is …

Tumors are thought rare in dinosaurs, previously limited in distribution to a single family–
hadrosaurs. Here we recognized two different neoplastic lesions, osteoma and …

Adult large-bodied theropods are often found with numerous pathologies. A large, almost
complete, probably adult Allosaurus specimen from the Howe Stephens Quarry, Morrison …

Reptiles are the only amniotes that maintain the capacity to regenerate appendages. This
study presents the first anatomical and histological evidence of tail repair with regrowth in an …

Studies on pathological fossil bones have allowed improving the knowledge of physiology
and ecology, and consequently the life history of extinct organisms. Among extinct …

Bones in the fossil record sometimes exhibit unusual structures that can be attributed to
pathologies, taphonomic alterations, or morphological variation. The goal of this work is to …

Osteomyelitis is reported for the first time in a sauropod dinosaur. The material (MCS‐PV
183) comes from the Anacleto Formation (Campanian, Late Cretaceous), at the Cinco Saltos …
