Understanding the origins of morphological specializations in mammals is a key goal in
evolutionary biology. It can be accomplished by studying dental homology, which is at the …

Third permanent molars (M3s) are the last tooth to form but have not been used to estimate
age at dental maturation in early fossil hominins because direct histological evidence for the …

Moulting is the process of shedding the exoskeleton, which all euarthropods must
periodically do to grow and develop. Moulting is of central importance in the life histories of …

The dentition is an extremely important organ in mammals with variation in timing and
sequence of eruption, crown morphology, and tooth size enabling a range of behavioral …

Arthodire placoderms have been proposed as the sister group of Chinese
'maxillate'placoderms plus all the more crownward gnathostomes. These basal groups …

Organs throughout the body develop both asymmetrically and symmetrically. Here, we
assess how symmetrical teeth in reptiles can be created from asymmetrical tooth germs …

The Miocene Santacrucian sloths are a very important assemblage because they represent
the first major radiation among sloths and, therefore, they could provide many insights about …

The goal of this study is to evaluate ecomorphological variables in glyptodonts from different
ages (Miocene to early Holocene), clades, and sizes, with the purpose of inferring their …

Ecological preferences and life history strategies have enormous impacts on the evolution
and phenotypic diversity of salamanders, but the yet established reliable ecological …

Paleozoic sphenacodontid synapsids are the oldest known fully terrestrial apex predators.
Dimetrodon and other sphenacodontids are the first terrestrial vertebrates to have strong …
