By Emily Lamb, Spencer Lutz, Madison Walsh, & Brittany Tanner
S
Classification
S Kingdom: Animalia
S Phylum: Chordata
S Subphylum: Vertebrata
S Class: Reptilia
Characteristics
S Ectotherms
S Tough, waterproof skin covered with scales
S Hard shelled eggs
S Strong jaws
S Lungs, no gills
S Carnivores, and herbivores
Advantages
S Internal fertilization
S Well developed jaws
S Energy- require less than warm blooded animals
S Amniotic eggs
Disadvantages
S Ectothermic
S Requires more care then fish or amphibians
S Few eggs produced
Evolution
S Originated around 340-335 million years ago, in the late late
Carboniferous period
S Evolved from advanced reptile-like amphibians that became
increasingly adapted to life on dry land
S Oldest reptile known = Hylonomus
S Small, lizard-like
S Insectivorous diet
Evolution
S Originally overshadowed by bigger amphibians
S Following the Carboniferous Rainforest Collapse,
amphibians were devastated, while reptiles fared well - they
were adapted to drier conditions
S Acquired new niches and feeding strategies
S Increased in diversity and dominated communities
S Mesozoic – Age of the Reptiles
S Diapsid and Anapsid are the “true reptiles”
Evolution
S Diapsid reptiles split into two main lineages
S Archosaurs (forebears of crocodiles and dinosaurs)
S Lepidosaurs (predecessors of modern snakes, lizards, and
tuatara).
S Both groups remained lizard-like and relatively small and
inconspicuous
