Baiotomeus is a genus of mammals from the extinct order of Multituberculata. It is known from the Paleocene of North America.
The genus Baiotomeus was formally named by Krause in 1987 (Krause, 1987), and has also been known as Mimetodon (partly), Neoplagiaulax (partly), and Ptilodus (partly).
Baiotomeus douglassi is a fairly substantial multituberculate weighing almost 200 g. Remains have been found in Montana and Wyoming in the United States, in strata of the Gidley Quarry dated to the Torrejonian stage of the Paleocene.
The species was originally named Ptilodus douglassi by Simpson in 1935 (Simpson, 1935), but it has been reclassified several times:
It was finally assigned to Baiotomeus by Hartman in 1986 — which is before Krause formally established the genus in 1987.
Remains of Baiotomeus lamberti have been discovered in Montana in the United States, in the Medicine Rocks of the Tongue River Formation, which have been dated to the Paleocene.
Several specimens, including the holotype, are at the Peabody Museum of Natural History at Yale. Collected in 1958 and 1965, these were originally described as belonging to Mimetodon. It was given its current name in 1987 by Krause (Krause, 1987). B. lamberti has also been confused with Ptilodus montanus.
Baiotomeus russelli has been discovered in Alberta, Canada, in Cochrane 2 of the Paskapoo Formation, which has been dated to the lower Tiffanian stage of the Paleocene.
