Class Mammalia
Order Artiodactyla
Family Camelidae
There is some question as to the nomenclatural status of Gigantocamelus; it may be a synonym of Titanotylopus (Kurtén and Anderson 1980). Vanderhill (1986) preferred to treat them as separate genera and to refer the New Mexican material to Gigantocamelus on the basis of the restricted geographic distribution of Titanotylopus (early Irvingtonian of Nebraska). He does point out that the two cannot be separated on the basis of limited post-cranial material.
The El Golfo record is given as Gigantocamelus sp. or Titanotylopus sp. (Croxen et al. 2007).
