If the bones he found are part of an ichthyosaur skeleton, the animal was a pretty small one, Henderson said. Consequently the apparently anomalous association of Trachy-ceras with Tropites in California can not be explained by assuming an early arrival of Tropites as suggested by Smith, but is due instead to the supposed occurrence of Trachyceras in an assemblage otherwise comparable to that of the Tropites subbul-latus zone.
