Taxonomy and classification

Leptomeryx

Tragulina is an infraorder within the larger suborder Ruminantia, and is the sister clade to the infraorder Pecora. Tragulina contains one extant (living) family, Tragulidae, as well as several extinct families, although the extinct members currently classified as within Tragulina causes it to be considered paraphyletic.^[2]

Tragulina's placement within Artiodactyla can be represented in the following cladogram:^{[3][4][5][6][7]}

Artiodactyla	Tylopoda (camels) Artiofabula Suina (pigs) Cetruminantia Ruminantia (ruminants) Tragulina Tragulidae (mouse deer) Pecora (horn bearers) Cetancodonta/Whippomorpha Hippopotamidae (hippopotamuses) Cetacea (whales)
