Cervinae

The Cervinae or the Old World deer, are a subfamily of deer. Alternatively, they are known as the plesiometacarpal deer, due to having lost the parts of the second and fifth metacarpal bones closest to the foot (though retaining the parts away from the foot), distinct from the telemetacarpal deer of the Capreolinae (which have instead retained these parts of those metacarpals, while losing the parts away from the foot instead).

Megaloceros (from Greek: + , literally "Great Horn"; see also Lister (1987)) is an extinct genus of deer whose members lived throughout Eurasia from the Pleistocene to the early Holocene. The type and only undisputed member of the genus, Megaloceros giganteus, vernacularly known as the "Irish elk" or "giant deer", is also the best known. Fallow deer are thought to be their closest living relatives. Megaloceros has been suggested to be closely related to other genera of "giant deer", like the East Asian genus Sinomegaceros and the largely European Praemegaceros, the species of both genera havin

Eucladoceros (Greek for "well-branched antler") is an extinct genus of large deer whose fossils have been discovered across Eurasia, from Europe to China, spanning from the Early Pliocene to the end of the Early Pleistocene. The various species of the genus are noted for their unusual comb-like or branching antlers, though antler shape varied considerably between different species.

Sinomegaceros is an extinct genus of deer known from the Late Pliocene/Early Pleistocene to Late Pleistocene of Central and East Asia. It is considered to be part of the group of "giant deer" (often referred to collectively as members of the tribe Megacerini), with a close relationship to Megaloceros. Many members of the genus are noted for their distinctive palmate antler brow tines.

Odocoileini is a tribe of deer, containing seven extant genera and several extinct ones.

Haploidoceros is an extinct genus of deer that lived in Europe from the late Middle Pleistocene to early Late Pleistocene. It contains a single species, '''Haploidoceros mediterraneus.''' It had a distribution limited to southern France and the Iberian Peninsula.
