Charles D. and Mary Vaux Walcott Research Fund.]. Condylarthra is an informal group – previously considered an order – of extinct placental mammals, known primarily from the Paleocene and Eocene epochs. They are considered early, primitive is now largely considered to be a wastebasket taxon, having served as a dumping ground for classifying ungulates which had not been clearly established as part of either Perissodactyla or Class: Mammalia.

We here describe the endocranial cast of the Eocene archaic ungulate Hyopsodus lepidus AMNH (Bridgerian, North America) reconstructed from X-ray computed microtomography data. This represents the first complete cranial endocast known for Hyopsodontinae.

The Hyopsodus endocast is compared to other known “condylarthran” endocasts, i. those of Pleuraspidotherium.

Fossil carnivorans are described from earliest Eocene localities in the Clarks Fork and southern Bighorn basins of Wyoming.

The Miocene was a long-lasting epoch in which the earth's climate rebounded from the cooling of the Oligocene and there was a marked increase in both global temperatures and the total number of mammal species.

Though warmer than the Oligocene, the polar ice caps remained in place. Carnivores, creodonts and carnivorous ungulates: Mammals become predators. Predation on mammals, among others by dinosaurs, was without doubt an important factor in the early evolution of this class of animals.

There are, on the other hand, only few Mesozoic mammals that could have been carnivorous, and probably none preyed on larger vertebrates. Dental variability and tarsal morphology of the European Paleocene/Eocene “condylarth” mammal Microhyus.

The Eocene is the second of five epochs in the Tertiary Period — the second of three epochs in the Paleogene — and lasted from about to million years ago.* The oldest known fossils of most of the modern orders of mammals appear in a brief period. A couple of rare mammal teeth (Order Perissodactyla) were found in the marine base of the Lede Sand of these specimens are housed in the collections of the Royal Belgian Institute of Natural Sciences.

These teeth most probably originate from the continental Aalterbrugge Lignitic Horizon (uppermost Ypresian), which is reworked in the basal gravel.

At the Paleocene/Eocene boundary, million years ago, mammal faunas undergo major evolutionary changes. The majority of modern-type placental orders appear simultaneously in Europe, North America and Asia, while archaic groups persisting since the Paleocene start to.

Two assemblages of fossil mammals from the lower part of the Eocene Buck Hill Group, Brewster County, Texas, contain two species of marsupials, five of primates, two of condylarths, one taeniodont, six of bunodont artiodactyls, and one uintathere.
