Comodon
Introduction '''''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.
Systematics ''Comodon'' was originally named ''Phascolodon'' by Simpson (1925) for USNM 2703, a mandible from Quarry  9 in Como Bluff, Wyoming. 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). Meanwhile, Cifelli & Dykes (2001) coined the replacement name ''Phascolotheridium'' for ''Phascolodon'', unaware of the paper by Kretzoi and Kretzoi (2000).
