Description
A generalized early mammal, it had a vaguely cat-like body, heavy head, long tail, and five-toed plantigrade feet ending in blunt nails that were neither hooves nor sharp claws. The foot bones articulated in a similar way to the feet of hoofed mammals, and the feet were probably not very flexible. The teeth had a selenodont structure; enamel ridges with crescent-shaped cusps. Selenodont teeth are found in modern grazers and browsers such as cattle and deer, but Pantolambda's teeth were low-crowned and indicate a not very specialized diet. Pantolambda probably ate a mix of shoots, leaves, fungi, and fruit, which it may have supplemented with occasional insects, worms, or carrion.
Cretaceous mammals, which had to compete with dinosaurs, were generally small insect eaters. Pantolambda was one of the first mammals to expand into the large-animal niches left vacant by the extinction of the dinosaurs. It was large for a Paleocene mammal, about the size of a sheep. Pantolambda and other early pantodonts would quickly evolve into heavy animals such as Barylambda and Coryphodon. These were the first large browsers, pioneering styles of life later followed by many unrelated groups of mammals: rhinos, tapirs, hippos, ground sloths, and elephants.
Pantodonts such as Pantolambda were definitely not tree dwellers. Fossils of the species of this genus have been found in these locations:
Pantolambda bath modon San Juan Basin, San Juan County, New Mexico San Juan County, Sandoval County, New Mexico
Pantolambda cavirictum San Juan Basin, San Juan County, New Mexico Fort Union Formation, Fremont County, Wyoming
Pantolambda intermedium Gidley Quarry, Montana

Famous quotes containing the word description:
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
“A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.”
—John Locke (1632–1704)
“An intentional object is given by a word or a phrase which gives a description under which.”
