Odocoileus is a genus of medium-sized deer (family Cervidae) containing three species native to the Americas. [1] [3] [4] The name, sometimes spelled odocoeleus, is a contraction of the Greek root odont- [5] [6] , meaning "tooth," and -coelus, New Latin for "hollow".

The genus Odocoileus was named by French zoologist, Constantine S. Rafinesque, in 1832, based on teeth and part of a jaw (presumably of Odocoileus virginianus) gathered by a Mr. Wardel from an anonymous cave in Carlisle, Pennsylvania on the banks of the Conococheague Creek, and kept in the collection of a Mr. Hayden of Baltimore. Rafinesque could refer these teeth to no other living animal known to him, despite having then lived in native white-tailed deer habitat for decades (although the white-tailed deer had been previously described in the literature, between 1850 and 1900 the white-tailed deer population was reduced to 300,000 to 500,000 individuals, found only in remote locations inaccessible to humans [8] ). Rafinesque described enamel that covered the tooth, including the hollow inside, and named the species Odocoileus speleus, for "teeth well hollowed" and speleus referring to a cave. [9] [10] [11]
