Moose-like restoration by Robert Bruce Horsfall

The stag-moose (Cervalces scotti) was a large, moose-like deer of North America during the Pleistocene epoch.[1] It is the only known North American member of the genus Cervalces. It was slightly larger than the moose, with an elk-like head, long legs, and complex, palmate antlers. Cervalces scotti reached 2.5 m (8.2 ft) in height and a weight of 708.5 kg (1,562 lb).[2] The species went 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.[3][4]

The first evidence of the stag-moose found in modern times was discovered at Big Bone Lick, Kentucky by William Clark, circa 1805. A more complete skeleton was found in 1885 by William Barryman Scott in New Jersey.[1] Mummified remains have also been found.[5]

The stag-moose frequented wetlands in a range from southern Canada to Arkansas and from Iowa to New Jersey. As the glaciers retreated, moose (which had crossed the Bering land bridge from Asia)[6] may have populated its habitat and caused its extinction by competition.[1] Although there is no paleontological evidence that it was associated with humans,[7] other theories for its extinction have been proposed. Notably, there is speculation that hunting by newly arrived humans caused the extinction of the stag-moose and other large mammals.[8] Additionally, some have proposed a sudden extinction by disease, brought by small mammals in association with humans.[4]
