Aclistomycter
Introduction '''''Aclistomycter''''' is an extinct genus of oreodont. It lived during the early Chadronian subepoch 37.2—33.9 mya, existing for approximately . from the Chambers Tuff Formation near Adobe Springs in Presidio County, Texas. ''Aclistomycter'' was a very small herbivorous artiodactyl with a short face, small, but tusk-like canine teeth.
Diagnosis The type specimen consists of a skull and jaws. Generic characters assigned by Wilson (1970):* Medium small merycoidodontid with very large and deep, probably perforated, antorbital fossae. * Brachycephalic. * Posterior part of skull extended. * Molar teeth with thick enamel and deep fossettes. * Posterior base of zygomatic processes wide, making the skull broad posteriorly. * Bullae thought to be inflated (though the bullae are not exposed in the figures of the type specimen illustrated by Wilson).
