Indian muntjac species to actually have antlers. Ancestor to muntjacs is the "Dicrocerus elegans" which is the oldest known deer to shed antlers. Other fossils found that deer species experienced a split of the Cervinae from the Muntiacinae, the latter of which remained of similar morphology. Muntjacs of this time during the Miocene were smaller than their modern counterparts. Molecular data has suggested that Indian and Fea’s muntjac share a common ancestor while giant muntjac are more closely related to Reeve’s muntjac. Although the muntjac deer has a long lineage, little has been studied in terms of their fossil record. The female
Leaf muntjac could be completely wrapped by a single large leaf. It is found in Myanmar and India. The leaf muntjac is uniquely found in dense forests of Myanmar, in the Hukawng Valley region to the Northeast of Putao, hence its scientific epithet, and to the south of the Nam Tamai branch of the Mai Hka River. It is found at an altitude of 450 to 600 m — the transition zone between tropical forests and temperate ones.
