Oligocene mammals from the Black Range, southwestern New Mexico
— Spencer G. Lucas
Abstract:
Fossil mammals from the upper part of the Rubio Peak Formation in the northern Black Range, Sierra County, New Mexico, are: Jaywilsonomys ojinagaensis Ferrusquia-Villafranca & Wood 1969, Perissodactyla gen. et sp. indet., Hypertragulidae?, and Montanatylopsus matthewi Prothero 1986. These mammals indicate an early Chadronian age (earliest Oligocene, about 36 Ma) and thus are the first Oligocene mammals recorded from New Mexico.
