text: The preserved cervical vertebrae are very unusual: the centra are short in length front-to-back (as in "pliosaurs"), broader than long or high (as in "cimoliasaurs"), with a strongly "binocular" shape, unlike the simple cylindrical shape of cervical vertebrae found in other known plesiosaurs (though Aristonectes has ovoid vertebrae toward the base of the neck).
