Summary:
Redbeds of Pato Red Member of Vaqueros Formation of English (1916) were assigned to Caliente Formation by Hill and others (1958). This usage is retained, and name Pato is considered obsolete. These beds contain sparse mammalian remains that suggest Arikareean age (J.G. Vedder, oral commun., 1968).
