F. J. Goin and M. A. Abello 2013Eomicrobiotherium di ers from other Microbiotheria in the following combination of features: post- cristid of m1–m2 obliquely set with respect to the dental axis; alveolar edge even at the p3–m1 boundary; low horizontal ra- mus; metaconid quite posteriorly placed with respect to the pro- toconid in m1–m2; and paraconid of m1–m2 not compressed anteroposteriorly.
