Dromedaries are not ruminants (suborder Ruminantia) but rather are
Tylopoda, a suborder of Artiodactyla, which also includes the 2-humped camel (Camelus bactrianus), wild Bactrian camel (C.
Bactrian camel (Camelus bactrianus), as a large mammal belonging to Camelus, Camelidae,
Tylopoda and Pacentalia (Corbet & Hill, 1991), is located in the desert, semi-desert regions in the north and northwest China.
Tylopoda (oromerycids, camelids, oreodontoids, protoceratids): Ms primitively bunoselenodont, quadrate, each with mesostyle plus bitubercular distal lobe bearing enlarged metaconule as distolingual cusp; ectomesocuneiform (North American origin).
Numerosa evidencia molecular (e.g., Waddell et al., 1999; Murphy et al., 2001) confirman la cercania de los Hippopotamidae con los Cetacea, incluso respaldada por datos morfologicos (Boisserie et al., 2005); sin embargo, la relacion con los otros subordenes de artiodactilos (Ruminantia, Suiformes,
Tylopoda) no ha sido completamente esclarecida y sigue sujeta a una mas precisa resolucion taxonomica.
Since the cones/conids are crescentic in outline, it can safely be included in Ruminantia and
Tylopoda (Romer, 1974; Zittel, 1925).
