The family Cervidae consists of 55 extant species belonging to 19 genera in 2 subfamilies and divided into dozens of extant subspecies. This does not include hybrid species or extinct prehistoric species. Additionally, one species, Schomburgk's deer, went extinct in 1938. [2] The classification is based on the molecular phylogeny.

[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 recent ice age, as part of a mass extinction of large North American mammals. [7] [8]
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 ...
Rabbits play an important part in the terrestrial food chain, eating a wide range of forbs, grasses, and herbs, and being part of the staple diet of many carnivorous species. Domestic rabbits can be litter box trained, and—assuming they are given sufficient room to run and a good diet—can live long lives as house pets.
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 ...

P. saundersiae Hewitt, 1927: Southern Africa: Size: 38–54 cm (15–21 in) long, plus 5–12 cm (2–5 in) tail [88] Habitat: Shrubland, grassland, and rocky areas [89]
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.
