Knowledge of plesiadapiform skeletal morphology and inferred ecological roles are critical
for establishing the evolutionary context that led to the appearance and diversification of …

Palaechthonid plesiadapiforms from the Palaeocene of western North America have long
been recognized as among the oldest and most primitive euarchontan mammals, a group …

The fossil record of early primates is largely comprised of dentitions. While teeth can indicate
phylogenetic relationships and dietary preferences, they say little about hypotheses …

In their paper ''Adaptive origins of primates revisited,''Soligo and Martin (2006) argued that
the common ancestor of primates of modern aspect (ie, euprimates) was larger than typically …

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 …

Objectives The disappearance of the North American plesiadapoids (stem primates, or
plesiadapiforms) in the latest Paleocene has been attributed to competition with rodents …

The earliest euprimates to arrive in North America were larger‐bodied notharctids and
smaller‐bodied omomyids. Through the Eocene, notharctids generally continued to increase …

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 …

Plesiadapiforms, appearing near the Cretaceous-Paleogene boundary, represent the first
primate radiation and show a diverse array of tooth morphologies. Dental topographic …

The Middle Paleocene paromomyid Palaechthon nacimienti has the most primitive cranial
anatomy known for any plesiadapoid. In relative size and functional morphology, its molars …
