S
Chordata Reptilia
By Emily Lamb, Spencer Lutz, Madison Walsh, & Brittany Tanner
Classification
Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Reptilia
Characteristics
Ectotherms Tough, waterproof skin covered with scales Hard shelled eggs Strong jaws Lungs, no gills Carnivores, and herbivores
Advantages
Internal fertilization Well developed jaws Energy- require less than warm blooded animals Amniotic eggs
Disadvantages
Ectothermic Requires more care then fish or amphibians Few eggs produced
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
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
Diapsid and Anapsid are the “true reptiles”
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
