For taphonomic and practical reasons, our understanding of morphological evolution within
and among species is based primarily on measurements taken from one or a few …

As a result of numerous fossil and subfossil finds of ostriches, there is great demand for a
comprehensive osteometric dataset for the living species and subspecies of the genus …

Demographic profiling of archaeological assemblages offers a window into the shifting
exploitation strategies practiced by ancient societies. High resolution sex-specific age …

We analyzed a comprehensive data set of ossification sequences including seven
marsupial, 13 placental and seven sauropsid species. Data are provided for the first time for …

Fossils provide our only direct window into evolutionary events in the distant past.
Incorporating them into phylogenetic hypotheses of living clades can help time-calibrate …

How do brain size and proportions relate to ecology and evolutionary history? Here, we use
virtual endocasts from 38 extinct and extant rodent species spanning 50+ million years of …

Non-avialan theropod dinosaurs had diverse ecologies and varied skull morphologies.
Previous studies of theropod cranial morphology mostly focused on higher-level taxa or …

The tuatara (Sphenodon punctatus) is the only living representative of Rhynchocephalia, a
group of small vertebrates that originated about 250 million years ago. The tuatara has been …

Mammals are the only living members of the larger clade Synapsida, which has a fossil
record spanning 320 Ma. Despite the fact that much of the ecological diversity of mammals …

Extant hyraxes are small, rabbit-sized, herbivorous paenungulates, with a notable feeding
mechanism: they crop with the molars instead of the incisors, unlike most modern hoofed …
