Cervalces scotti reached 2.5 m (8.2 ft) in length and a weight of 708.5 kg (1,562 lb). [4] [5] The stag-moose resided in North America during an era with other megafauna such as the woolly mammoth, ground sloth, long horn bison, and saber toothed cat. [6] The species became extinct approximately 11,500 years ago, toward the end of the most ...
Later species reduced the number of toes, and developed teeth more suited for grinding up grass and other tough plant food. Rhinocerotoids diverged from other perissodactyls by the early Eocene. Fossils of Hyrachyus eximus found in North America date to this period. This small hornless ancestor resembled a tapir or small horse more than a rhino.
Cervalces latifrons, the broad-fronted moose, or the giant moose [3] was a giant species of deer that inhabited Europe and Asia during the Pleistocene epoch. It is thought to be the ancestor of the modern moose, as well as the extinct North American Cervalces scotti. It was considerably larger than living moose, placing it as one of the largest ...
Alces is a genus of artiodactyl mammals, that includes the largest species of the deer family. [1] There are two species in genus: the moose (Alces alces) and the fossil Alces gallicus (also known as the Gallic moose), that existed in the Pleistocene about 2 million years ago.
Figure 1:In mammals, the quadrate and articular bones are small and part of the middle ear; the lower jaw consists only of dentary bone.. While living mammal species can be identified by the presence of milk-producing mammary glands in the females, other features are required when classifying fossils, because mammary glands and other soft-tissue features are not visible in fossils.

The term rabbit is typically used for all Leporidae species, excluding the genus Lepus. Members of that genus are known as hares [20] or jackrabbits. [21] Lepus species are precocial, born relatively mature and mobile with hair and good vision out in the open air, while rabbit species are altricial, born hairless and blind in burrows and buried ...
An evolutionary tree (of Amniota, for example, the last common ancestor of mammals and reptiles, and all its descendants) illustrates the initial conditions causing evolutionary patterns of similarity (e.g., all Amniotes produce an egg that possesses the amnios) and the patterns of divergence amongst lineages (e.g., mammals and reptiles ...
