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 …

Individual age and population age composition are the major concerns of ecologists,
evolutionary biologists and conservation biologists. In amphibians, skeletochronology …

Histology-based skeletochronology is a widely used approach to determine the age of an
individual, and is based on the assumption that temporal cessations or decelerations of …

Dinosauria debuted on Earth's stage in the aftermath of the Permo-Triassic Mass Extinction
Event, and survived two other Triassic extinction intervals to eventually dominate terrestrial …

The Eocene history of cetacean evolution is now represented by the expansive fossil record
of archaeocetes elucidating major morphofunctional shifts relating to the land to sea …

The interest in mammalian palaeohistology has increased dramatically in the last two
decades. Starting in 1849 via descriptive approaches, it has been demonstrated that bone …

The early evolution of toothless baleen whales (Chaeomysticeti) remains elusive, despite a
robust record of Eocene–Oligocene archaeocetes and toothed mysticetes. Eomysticetids, a …

We present a detailed histological study of long bones from an ontogenetic series of
Mussaurus patagonicus, an early sauropodomorph from the Lower Jurassic of Argentina …

Poposaurus gracilis is a bipedal pseudosuchian archosaur that has been poorly understood
since the discovery of the holotype fragmentary partial postcranial skeleton in 1915 …

Background Osteohistological examinations of fossil vertebrates have utilized a number of
