vallesaurus造句

• Senter found that " Hypuronector ", originally described as a drepanosaurid, actually lies just outside that family, along with the primitive drepanosaur " Vallesaurus ".
• In addition, " Vallesaurus " also differs from " Hypuronector ", a related drepanosaur, in having anteroposteriorly extended neural spines of the anterior dorsal vertebrae and forelimbs much shorter than the hindlimbs.
• "Vallesaurus " differs in some characteristics from another drepanosaur, " Megalancosaurus " . " Vallesaurus " has a proportionally shorter and higher snout, a thicker and larger maxilla and set of maxillary teeth, and a shorter cervical vertebra.
• "Vallesaurus " differs in some characteristics from another drepanosaur, " Megalancosaurus " . " Vallesaurus " has a proportionally shorter and higher snout, a thicker and larger maxilla and set of maxillary teeth, and a shorter cervical vertebra.
• It also lacks the fusion between the neural spines of the second and third dorsal vertebrae . " Vallesaurus " differs from " Drepanosaurus ", another drepanosaur, in that it lacks the enormous claw found on the second digit of the manus.
• Another more inclusive taxon, Elyurosauria ( " lizard with coiled tails " ), was erected, in order to include all the drepanosaurs with coiled tails, " Vallesaurus " is thus more derived than " Hypuronector " ( as clearly shown by its morphology ) . " Drepanosaurus " and " Megalancosaurus " are also in a new taxon named Megalancosaurinae.
