摘要:

A fragmentary maxilla of an omomyid primate, probably referable to Ekgmowechashala, is described from the John Day Formation of Oregon. Ekgmowechashala is otherwise known only from lower jaw fragments from South Dakota. Similarities between the John Day specimen and early Oligocene Rooneyia strengthen the probability that Ekgmowechashala evolved from a form closely related to Rooneyia.
