Inferring the body mass of fossil taxa, such as non‐avian dinosaurs, provides a powerful tool
for interpreting physiological and ecological properties, as well as the ability to study these …

Background Body size is intimately related to the physiology and ecology of an organism.
Therefore, accurate and consistent body mass estimates are essential for inferring …

We report a time-calibrated stratigraphic section in Colorado that contains unusually
complete fossils of mammals, reptiles, and plants and elucidates the drivers and tempo of …

Abstract The Cretaceous–Paleogene mass extinction approximately 66 million years ago is
conventionally thought to have been a turning point in mammalian evolution,. Prior to that …

Body mass is a key parameter for understanding the physiology, biomechanics, and ecology
of an organism. Within paleontology, body mass is a fundamental prerequisite for many …

Scaling relationships between skeletal dimensions and body mass in extant birds are often
used to estimate body mass in fossil crown-group birds, as well as in stem-group avialans …

Haramiyida was a successful clade of mammaliaforms, spanning the Late Triassic period to
at least the Late Jurassic period, but their fossils are scant outside Eurasia and Cretaceous …

The evolution of the mammalian middle ear is thought to provide an example of
'recapitulation'—the theory that the present embryological development of a species reflects …

Since the 1984 discovery of the Nariokotome Homo erectus/Homo ergaster skeleton, it has
been almost axiomatic that the emergence of Homo (sensu stricto) was characterized by an …

Reconstructing the evolutionary history of island biotas is complicated by unusual
morphological evolution in insular environments. However, past human-caused extinctions …
