  1. ChordataReptilia By Emily Lamb, Spencer Lutz, Madison Walsh, & Brittany Tanner

  2. Classification • Kingdom: Animalia • Phylum: Chordata • Subphylum: Vertebrata • Class: Reptilia

  3. Characteristics • Ectotherms • Tough, waterproof skin covered with scales • Hard shelled eggs • Strong jaws • Lungs, no gills • Carnivores, and herbivores

  4. Advantages • Internal fertilization • Well developed jaws • Energy- require less than warm blooded animals • Amniotic eggs

  5. Disadvantages • Ectothermic • Requires more care then fish or amphibians • Few eggs produced

  6. Evolution • Originated around 340-335 million years ago, in the late late Carboniferous period • Evolved from advanced reptile-like amphibians that became increasingly adapted to life on dry land • Oldest reptile known = Hylonomus • Small, lizard-like • Insectivorous diet

  7. Evolution • Originally overshadowed by bigger amphibians • Following the Carboniferous Rainforest Collapse, amphibians were devastated, while reptiles fared well - they were adapted to drier conditions • Acquired new niches and feeding strategies • Increased in diversity and dominated communities • Mesozoic – Age of the Reptiles

  8. Diapsid and Anapsid are the “true reptiles”

  9. Evolution • Diapsid reptiles split into two main lineages • Archosaurs (forebears of crocodiles and dinosaurs) • Lepidosaurs (predecessors of modern snakes, lizards, and tuatara). • Both groups remained lizard-like and relatively small and inconspicuous

  10. Sea Turtles • Order: Testudines • Characterized by… • Large streamline shell • Flippers • Neat facts • Endangered population • Life Cycle • Migration

  11. Common Garter Snake • Order and Characteristics • Order-Squamata • Different color and stripes • Habitat and Hibernation • Mating • Jacobson Organ
