Metahapalodectes is an extinct mesonychid mesonychian from Late Eocene strata of Southeastern Mongolia.[1]

Similar to Lohoodon, Metahapalodectes was originally described as a large hapalodectid[2] on the basis of teeth and jaw fragments very similar to Hapalodectes, but suggesting an animal comparable in size to Mesonyx. In 1987, Ting & Li refer Lohoodon and Metahapalodectes to Mesonychidae due to the lower molar teeth of both genera lacking a re-entrant groove on the mesial or anterior side, a feature diagnostic of Hapalodectidae.[3][4]
