Apatodon mirus is a dubious and possibly invalid genus of dinosaur known from a single, now lost, vertebra.

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.[1] Marsh had misidentified the neural spine as the tooth of a pig-like animal (Baur, 1890).[2]

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.[3] The issue is now beyond resolution; however, as the type bone fragment has been lost.[4]

The name was derived from Greek: απατη ("trick", "deceit") and οδους (genitive οδοντος) ("tooth", in reference to its original, incorrect identification).
