It's a member of the family Allodontidae within the order Multituberculata. The genus Psalodon was named by Simpson in 1926. There are perhaps three species. It is also known as Allodon ("different tooth") and Ctenacodon ("comb tooth"). Present in stratigraphic zones 2 and 5.[1] Species The species Psalodon fortis was named by Othniel Charles Marsh in 1887 and G. G. Simpson in 1927. It is also known as Allodon fortis (Marsh 1887). Remains have been found in the Upper Jurassic Morrison Formation of Wyoming (USA). The holotype is at the Peabody Museum of Natural History at Yale University. The uncertain species ?Psalodon marshi was named by Simpson G.G. in 1929 to cover several Peabody specimens of possible P. species. All of the remains came from the Morrison Formation of Wyoming. The species Psalodon portens was named by Marsh O.C. in 1887 and Simpson G.G. in 1927. It is also known as Ctenacodon portens (Marsh 1887). The remains assigned to this species were also found in the Morrison Formation of Wyoming and the holotype is also at Yale. References * Simpson (1927), Mesozoic Mammalia. VII.
