Diapsid: member of an amniote clade distinguished by a pair of holes on each side of the skull. Dinosaur: member of an extremely diverse clade of reptiles varying in body shape, size, and habitat. Ectothermic: referring to organisms for which external sources provide most of the heat for temperature regulation. Endothermic: referring to organisms that are warmed by heat generated by their own metabolism. This heat usually maintains a relatively stable body temperature higher than that of the external environment. Gnathostome: member of the vertebrate subgroup possessing jaws.
