Taxonomy edit

The genus Cimolodon was named by Othniel Charles Marsh in 1889. Kielan-Jaworowska & Hurum (2001) noted that Cimolodon seems to be more closely related to members of their "Paracimexomys" group than to other ptilodontoideans.[4]

Species edit

Cimolodon electus (Fox R.C. 1971) is known from the Upper Cretaceous of the Upper Milk River Formation in Alberta, Canada. Possible finds have been reported from New Mexico.[5]

Cimolodon nitidus (Marsh O.C. 1889) is known from Late Cretaceous strata of the Lance Formation of Wyoming, Utah, Montana and South Dakota (United States) as well as Alberta and Saskatchewan (Canada). Synonyms include Allacodon lentus (Marsh, 1889); Allacodon rarus (Marsh, 1892); Cimolomys bellus (Marsh, 1889); Cimolomys digona (Marsh, 1899); Cimolomys nitidus; Halodon serratus (Marsh, 1889); Nanomyops minitus (Marsh, 1892); Nanomys minitus (Marsh, 1889); and Ptilodus serratus (Gidley, 1909). Cimolodon parvus (Marsh O.C. 1892) is also known from the Upper Cretaceous Lance Formation of Wyoming.[6][7] A specimen referred to as C. cf. nitidus has been recovered from the Prince Creek Formation.[8]

Cimolodon similis (Fox R.C. 1971) is known from the Late Cretaceous (Santonian-early Campanian) of Alberta and Utah.[9][10] C. wardi is known from the Wahweap Formation of Utah.[3]

Cimolodon akersteni is known from the Cenomanian-age Wayan Formation of Idaho.[11]
