Aclistomycter is an extinct genus of oreodont. It lived during the early Chadronian subepoch 37.2—33.9 mya, existing for approximately 3 million years. 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).
