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 ...
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.

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.

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 idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).
