Info

Genus

Etymology: \\\"deceptive tooth\\\" named for what Marsh thought was \\\"a portion of a lower jaw\\\" of an animal with a tooth deceptively resembling \\\"in form and superior surface of the crown, that of a typical Suilline [pig].

Holotype: (USMN coll.) partial vertebra (lost) Originally described as the partial mandible of a large suid mammal, but Baur (1890) identified it as a partial dinosaurian vertebra. What exactly it is will remain a mystery, as the specimen is lost. Olshevsky (1991) synonymized it with Allosaurus, but there is no justification for this. It is Dinosauria indet.
