To discover interordinal relationships of living and fossil placental mammals and the time of
origin of placentals relative to the Cretaceous-Paleogene (K-Pg) boundary, we scored 4541 …

Primates are the most visually adapted order of mammals. There is a rich history within
anthropology of proposed explanations for the adaptive significance of binocular vision …

Very shortly after the disappearance of the non‐avian dinosaurs, the first mammals that had
features similar to those of primates started appearing. These first primitive forms went on to …

The now widespread use of non‐destructive X‐ray computed tomography (CT) and micro‐
CT (µCT) has greatly augmented our ability to comprehensively detail and quantify the …

Plesiadapiforms are central to studies of the origin and evolution of primates and other
euarchontan mammals (tree shrews and flying lemurs). We report results from a …

Phylonyms is an implementation of PhyloCode, which is a set of principles, rules, and
recommendations governing phylogenetic nomenclature. Nearly 300 clades-lineages of …

Mammals with more rapid and agile locomotion have larger semicircular canals relative to
body mass than species that move more slowly. Measurements of semicircular canals in …

Arboreal primates have distinctive intrinsic hand proportions compared with many other
mammals. Within Euarchonta, platyrrhines and strepsirrhines have longer manual proximal …

We describe a virtual endocast produced from ultra high resolution X-ray computed
tomography (CT) data for the microsyopid, Microsyops annectens (middle Eocene …

Extant primates are distinctive among mammals in having relatively large brains. As stem
primates, Paleogene plesiadapiforms provide direct information relevant to the earliest …
