Discussion. Tebedge (1988:206) assigned a juvenile posterior horn core to this genus based on the prominent groove on the posterior horn, the strong divergence of the horns antero-posteriorly, and the elliptical shape of the posterior horn in cross-section." I consider it most likely to represent Stockoceros and have not added it to the Dark Canyon faunal list.
Van Devender et al. (1985) listed Tetrameryx sp. from La Brisca, noting that the tooth was larger than those of Stockoceros, Antilocapra, and Capromeryx, but that the enamel pattern was similar to antilocaprids—and thus they assigned it to Tetrameryx.
Late Blancan: 111 Ranch (Morgan and White 2005: ?).
Sangamon: La Brisca (Van Devender et al. 1985).
Literature. Morgan and White 2005; Tebedge 1988; Van Devender et al. 1985.
