Dinnetherium is an extinct genus of mammaliaforms from the Early Jurassic of Arizona. The type species, D. nezorum, was named in 1983. [1] It was discovered in a Sinemurian layer of the Kayenta Formation, [2] within the Gold Spring Quarry 1. The holotype is MNA V3221, which is a partial right mandible. [3]
Dinnetherium has sometimes been placed in the family Megazostrodontidae, but in 2011 the monotypic family Dinnetheriidae and order Dinnetheria were erected for the genus. [3]
