''Apatodon'' is a dubious genus of dinosaur. When Marsh named it, he thought it was a jaw with a tooth from a Mesozoic pig, but it was soon shown that the specimen was an eroded vertebra, from a dinosaur possibly from the Morrison Formation of Garden Park, Colorado.〔Marsh, 1877. Notice of some new vertebrate fossils. American Journal of Arts and Sciences. 14, 249-256.〕 Marsh had misidentified the neural spine as the tooth of a pig-like animal (Baur, 1890). The only recovered specimen is not regarded as sufficient to identify a particular species of dinosaur. However, George Olshevsky considered ''Apatodon'' to be synonymous with ''Allosaurus fragilis''.〔Olshevsky, 1991. A revision of the parainfraclass Archosauria Cope, 1869, excluding the advanced Crocodylia. Mesozoic Meanderings. 2, 196 pp.〕 The issue is now beyond resolution; however, as the type bone fragment has been lost.〔http://theropoddatabase.com/Non-theropods.htm#Apatodonmirus〕 The name was derived from Greek: απατη ("trick", "deceit") and οδους (genitive οδοντος) ("tooth", in reference to its original, incorrect identification). ==References== *Baur, G. 1890.
