(Artiodactyla, Ruminantia) from the Middle Miocene Chinji Formation of Pakistan.
Mouse deer belongs to the family Tragulidae, known to evolve very early from Oligocene as primitive ruminant .

Dorcabune anthracotherioides (Artiodactyla, Ruminantia, Tragulidae) from Hasnot, the Middle Siwaliks, Pakistan.
Dorcabune nagrii (Ruminantia, Tragulidae) from the Upper part of the Middle Siwaliks.
Tragulidae is the most primitive family among existing ruminants (Milne-Edwards, 1864; Carlsson, 1926; Duwe, 1969; Todd, 1975; Dubost, 1978; Webb and Taylor, 1980; Janis and Scott, 1987; Perez-Barberia and Gordon, 2000; Khan et al., 2012).
The lower molars represent the M structure (Dorcatherium fold and Tragulus fold) and this reflects the affinity with the family Tragulidae and the genus Dorcatherium.
A review of the distribution of all species of deer (Tragulidae
Moschidae and Cervidae) in China.
Fossil Tragulidae are mainly represented by the extinct genus Dorcatherium Kaup and Scholl 1834 with 22 recognized species during the MiocenePliocene (RAlssner 2007) exceeding by far the specific diversity of other genera such as Siamotragulus Thomas Ginsburg Hintong and Suteethorn 1990 Dorcabune Pilgrim 1910 and Yunnanotherium Han 1986.
Suborder Ruminantia Scopoli 1777 Family Tragulidae Milne-Edwards 1864
The fauna mainly consists of Artiodactyla (Cervidae, Tragulidae
, Giraffidae, Suidae), Perissodactyla (Equidae, Rhinocerotidae), Proboscidea (Trilophodon hasnotensis, Synconolophus dhokpathanensis) and Primates (Cercopethicoids) (Ghaffar et al., 2009; Iqbal et al., 2009; Khan et al., 2008a-b, 2009a-b, 2010, 2011, 2012).
Ruminantia comprises four families namely, Tragulidae
, Cervidae, Bovidae and Giraffidae.
As noted by earlier researchers, this genus embraces the major part of the Miocene-Pliocene diversity of the Tragulidae, with 22 recognized species, exceeding other genera such as Siamotragulus, Dorcabune, Afrotragulus and Yunnanotherium by far in species diversity (ROssner, 2007; Quiralte et al., 2008; Sanchez et al., 2010).
The semi-selenodonty pattern of the molars confirms the inclusion of this specimen in Tragulidae (Colbert, 1935; Pickford, 2001; Morales et al., 2003; Pickford et al., 2004).
