Major evolutionary transitions, in which animals develop new body plans and adapt to
dramatically new habitats and lifestyles, have punctuated the history of life. The origin of …

Carnivores (cats, dogs and kin) are a diverse group of mammals that inhabit a remarkable
range of ecological niches. While the relationship between ecology and morphology has …

Phylogenetic relationships among extinct hominoids (apes and humans) are controversial
due to pervasive homoplasy and the incompleteness of the fossil record. The bony labyrinth …

Although originally described almost three decades ago, the holotype of Irritator challengeri
from the Lower Cretaceous Romualdo Formation of Brazil still represents the most complete …

Crocodylians today live in tropical to subtropical environments, occupying mostly shallow
waters. Their body size changes drastically during ontogeny, as do their skull dimensions …

The bony labyrinth contains phylogenetic information that can be used to determine
interspecific differences between fossil hominins. The present study conducted a …

With their past and current diversities, West Indian caviomorph rodents dominate the
terrestrial mammalian fauna of the Caribbean archipelago. Many of these species have …

The vestibular system of the mammalian inner ear senses angular and linear velocity of the
head and enables animals to maintain their balance. Vestibular anatomy has been studied …

The bony labyrinth (inner ear) of mammals reveals systematic as well as morphofunctional
information. However, detailed knowledge of bony labyrinth morphology and ontogeny in …

The semi-circular canals in the inner ear sense head rotations. It is widely recognised that
the anatomy of the semi-circular canals is often adapted to the species-specific agility, in …
