1.  Chordata Reptilia By Emily Lamb, Spencer Lutz, Madison Walsh, & Brittany Tanner

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

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

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

6. Disadvantages  Ectothermic  Requires more care then fish or amphibians  Few eggs produced

7. 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

8. 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

9.  Diapsid and Anapsid are the “true reptiles”

10. 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

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

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