Mammals have two apomorphies in the ear region: an elongated cochlear canal and an
eminence on the tympanic side of the cochlear housing, known as the petrosal …

Little is known about the early evolution of the brain in rodents. We report on nine new virtual
endocasts for one of the most primitive family of rodents, Ischyromyidae, based on five …

Several detailed studies of the external morphology of the ear region in extinct sloths have
been published in the past few decades, and this anatomical region has proved extremely …

The new species Acdestis maddeni is described based on the most complete skull of a
palaeothentid marsupial known so far. The skull preserves most of the upper dentition and of …

Seymouria is among the best‐known stem amniotes and holds an important phylogenetic
position for discussions of amniote evolution. Previous work has focused primarily on the …

The goal of this project is to document the ontogeny of the cranial (brain) endocast of
Struthio camelus, the African ostrich. Comparison of size and shape via 3D reconstruction …

Anagalids are an extinct group of primitive mammals from the Asian Palaeogene thought to
be possible basal members of Glires. Anagalid material is rare, with only a handful of crania …

After successfully diversifying during the Paleocene, the descendants of the first wave of
mammals that survived the end‐Cretaceous mass extinction waned throughout the Eocene …

There is huge divergence in the size and complexity of vertebrate brains. Notably, mammals
and birds have bigger brains than other vertebrates, largely because these animal groups …

The primate ectotympanic bone form is frequently used in anthropology as a discrete
characteristic with strong phylogenetic signaling among primates; however, the proximate …
