Tinodon is an extinct genus of mammal. First described by the paleontologist Othniel Charles Marsh, it contains two recognized species: Tinodon bellus and T. micron. It is known from jaw and dental remains. Its taxonomic placement within the mammalian lineage remains uncertain, having been variously placed within and outside of the crown group Mammalia. It lived from the Late Jurassic to the Early Cretaceous, found in both North America and Europe. Its known habitats are believed to have ranged from semi-arid to arid.
