30,000 years ago. The area in which the fossil was found and the date implies that Cervalces scotti lived before a massive ice sheet covered the area in which it inhabited, which could also be a possible cause of its extinction. Since the stag-moose resided in a woodland habitat, climate change and loss of natural pastures also could have played a role in its extinction. Cervalces scotti probably lived in a narrow geographic range, characterized by a spruce-dominant mixed conifer and deciduous wet woodland which may have made it more vulnerable to extinction. Remains of Cervalces scotti found in modern-day Ohio have suggested that it and Homo sapiens could have possibly interacted. Fossils of both Cervalces scotti and other large extinct mammals in the area suggest that it have been a frequent target of early human hunters. Remains of the stag moose, along with Paleo Indian artifacts and the remains of the flat-headed peccary, giant short-faced bear, and the giant beaver were found in the Sheriden Cave in Wyandot County, Ohio. Palaeobiology Cervalces scotti, like several other members of its genus, probably lived in marshes, swamps and bogs, as well as spruce-taiga floral communities. There were also surroundings ranging from tundra–mixed coniferous forests to deciduous woodlands. These sedges and willows may have not have been suitable food products, but they provide an imagery of the ecology of the stag-moose. The change in flora and fauna due to complete deglaciation probably also affected the living conditions of the stag-moose in states like Iowa and Wisconsin, where the stag-moose was found at more than 20 sites. None of these sites, however, has any evidence that the stag-moose interacted with humans, furthering evidence that the extinction of the stag-moose is not comparable to that of large herbivores that were greatly affected by hunting. The stag-moose reproduced more often than megaherbivores, and so the hypothesis is that the stag-moose's disappearance is linked to the emergence of the "true moose" (Alces alces), instead. Another reason for extinction could be the competition of several herbivorous artiodactyls, like the Bison in the new grassland ecosystem which replaced the spruce forest environment.
