Comodon is an extinct genus of Late Jurassic mammal from the Morrison Formation of Wyoming. Fossils of this taxon are present in stratigraphic zone 5.Foster, J. (2007). "Appendix." Jurassic West: The Dinosaurs of the Morrison Formation and Their World. Indiana University Press. pp. 327-329.
Systematics Comodon was originally named Phascolodon by Simpson (1925) for USNM 2703, a mandible from Quarry 9 in Como Bluff, Wyoming.G. G. Simpson. 1925. Mesozoic Mammalia 1. American triconodonts: part 2. American Journal of Science, series 5 10:334-358 However, the name Phascolodon was already in use for a ciliophore described in 1859, and the replacement name Comodon ("tooth from Como Bluff") was erected by Kretzoi & Kretzoi (2000).Kretzoi, M. and Kretzoi, M. 2000. Fossilium Catalogus 1: Animalia. Pars137—Index Generum et Subgenerum Mammalium. 726 pp. BackhuysPublishers, Leiden. Meanwhile, Cifelli & Dykes (2001) coined the replacement name Phascolotheridium for Phascolodon, unaware of the paper by Kretzoi and Kretzoi (2000).Cifelli, R.L. and Dykes, T.D. 2001. Phascolotheridium, a new name for the genus Phascolodon Simpson, 1925 (Vertebrata, Mammalia) preoccu−pied by Phascolodon Stein, 1859 (Ciliophora, Phyllopharyngea).
