''Cervalces latifrons'', the broad-fronted moose, was a large, moose-like deer of the holarctic regions of Europe and Asia dating from the Pleistocene epoch. It is believed to be the largest species of deer that ever existed and is known only from its fossil remains. It was a species of the genus ''Cervalces''. ==Description==
''Cervalces latifrons'' was first described by Mr Randall Johnson in 1874.〔''Annals and Magazine of Natural History: Zoology, Botany, and Geology'' Series 4, vol. 13 (1874).〕 A frontal bone attached to part of an antler of a previously unknown species of deer was found at low tide on the beachfront at Happisburgh, Norfolk, in the "Forest Bed". Johnson, who retained the specimen in his collection, named it ''Cervus latifrons'',〔"Forest bed ungulata", ''Memoirs of the Geological Survey of Great Britain, Museum of Economic Geology in London'', 1882:58.〕 ''Cervus'' being the only genus of deer known at that time. The specific name "latifrons" refers to the wide frontal bone of this large species. The morphology of the animal as deduced from this fossil and from others later found in this formation and on the Continent differs little from modern moose. It was later placed in the genus ''Cervalces'' which it shares with the also extinct ''Cervalces scotti'' from North America. The antlers of the males had short beams and large palmate lobes with up to ten large points. They were probably for display purposes to impress the female rather than for fighting because these moose are believed to have roamed as solitary individuals. ''Cervalces latifrons'' is probably the largest species of deer that has ever existed, with a shoulder height of .〔〔 It was about the same size as the American bison (''Bison bison'') and weighed about twice as much as the Irish elk (''Megaloceros giganteus'') but the span of its antlers at was smaller than that of the elk.〔〔
