  1. ? Synapsids Anapsids Diapsids Lepidosaurs Archosaurs Fig 12-3

  2. Saurischian dinos “Lizard-hips” Who are they? Archosaur relationships Ornithischian dinos “Bird-hips” Pterosaurs Other saurischians Crocs Birds Fig 16-2

  3. Crocodilians Slow, lethargic predators…

  4. Right!

  5. Breathing while running: solutions in lepidosaurs Monitor lizards use gular (throat) pumping Some other lizards just Stand up and run

  6. Crocs ( and dinos?) muscles pulling liver backward and “rocking” pelvic bones

  7. Adaptations: Secondary palate and palatal valve. Function? Tongue salt glands of crocs and gharials Pressure sensors

  8. Nocturnal vision

  9. Reproduction

  10. Temperature Dependent Sex Determination TDS Higher temps = males in croc Higher temps = females in turtles “Hard pressed evolutionists: All this leaves the poor evolutionist in a difficult situation. Whatever arguments that could be fabricated to support one mode of sex determination disintegrates when one considers the other group. Could this whole sex-in-response-to-temperature thing have been designed by a Creator with a sense of humor? It seems to me this takes far less faith to accept than some yet-to-be-conceived alleged advantage of allowing temperature to determine sex one way in crocodilians and the opposite way in most, but not all turtles. It really is difficult remaining an evolutionist! I know, for I couldn't do so after looking objectively at the facts. Can you? Should you? “ E. Norbert Smith, Ph.D.

  11. Beware the False Dichotomy of religion vs evolution How could phylogeny explain the difference between turtles and crocs? Would this predict they would be the same or different??

  12. True flapping flight – but different from any other flier

  13. Pterodactyl diversity

  14. Dinosaurs Lizard –hipped vs Bird-Hipped Bird

  15. Birds are from Saurischians!!! Bird

  16. Saurischian and Ornithischian are two alternate solutions to moving hind limb

  17. Ornithischians

  18. Saurischians Herbivorous Sauropods Carnivorous theropods

  19. Bird Archaeopteryx

  20. Note the intermediate condition Of this early bird
