Pictures from lecture slides on class canvas website. A reptile is a tetrapod vertebrate with. Cold blooded: same temperature as its surroundings, if it soaks up heat in the sun it becomes active, this is called ectothermic. Warm blooded animals are endothermic, they maintain their temperatures by metabolic means, expend a lot of energy to keep temp constant. Homeothermic means maintaining a relatively stable body temperature regardless of outside temperature. Paleontologists only use skeletal structures to define groups of organisms. A group of organisms of the same type if a taxon. The term taxonomy is derived from the greek word taxis (arrangement) and nomos (law) Taxonomy is the study of groups and is mostly related to naming organisms, hierarchal system of groupings. Swedish botanist carl von linne created linnaean system of taxonomy in 1735. Species of organisms can be grouped into higher categories called genera/genus. One latin name to indicate the genus and one name for species.
