Primitive diapsid skull; vertebrae biconcave; quadrate immovable;parietal eye present; two extant species in the genus Sphenodon.Superorder Ichthyosauria (ik'thee-o-sor'ee-uh) (Gr. ichthys, fish, + sauros, lizard). Mesozoicmarine dolphin-shaped diapsids with reduced limbs. All extinct.Superorder Sauropterygia (sor-op-ter-ig'ee-uh) (Gr. sauros, lizard, + pteryginos, winged).Mesozoic marine reptiles. All extinct.Order Plesiosauria (plees' ee-o-sor' ee-uh) (Gr. plesios, near, + sauros, lizard). Long-neckedMesozoic marine reptiles with paddlelike limbs. All extinct.Superorder Archosauria (ark'uh-sor'ee-uh) (Gr. archon, ruling, + sauros, lizard). Advanceddiapsids, mostly terrestrial, but some specialized for flight; gizzard present.Order Crocodilia (crok'uh-dil'ee-uh) (1. crocodilus, crocodile): crocodilians. Skull elongateand massive; nares terminal; secondary palate present; four-chambered heart; vertebraeusually concave in front; forelimbs usually of five digits; hindlimbs of four digits; quadrateimmovable; advanced social behavior; 23 species.Order Pterosauria (ter'uh-sor' ee-uh) (Gr. pteron, winged, + sauros, lizard). Flying, Mesozoicarchosaurs with membranous wings; extensive radiation. All extinct.Order Saurischia (sor-ish'ee-uh) (Gr. sauros, lizard,+ ischion, hip). Mesozoic dinosaurs;bipedal carnivores and quadrupedal herbivores; primitive (reptilian) hip structure.All extinct.Suborder Sauropodomorpha (sor'uh-pod-uh-morf'uh) (Gr. sauros, lizard, + podos, foot, +morphe, form). Herbivorous saurischians including Mesozoic giants such asBrachiosaurus, Apatosaurus and Diplodocus.Suborder Theropoda (the-ro'po-duh) (Gr. ther; wild beast, + podos, foot). Carnivoroussaurischians including huge predators such as Tyrannosaurus and small, agilepredators such as Deinonychus and Velociraptor. Birds are descended from thislineage.Order Ornithischia (orn'uh-thish'ee-uh) (Gr. ornis, bird, + ischion, hip).

Permianand Triassic synapsids with many mammal-like characteristics; carnivores andherbivores. Living mammals are descended from this lineage.
