According to the federal Endangered Species Act (ESA), an endangered species is one that is in danger of extinction throughout all or part of its range, whereas a threatened species is one likely to become endangered in the foreseeable future throughout all or parts of its range. The close of the Cretaceous period saw the demise of the Mesozoic era reptilian megafauna. hello to everyone. The classification of reptiles is more complicated and convoluted. These larvae undergo metamorphosis to become adults and live on land. In snakes the lungs are simple saclike structures having small pockets, or alveoli, in the walls. Important developments in the transition from reptile to mammal were the evolution of warm-bloodedness, of molar occlusion, of the three-ossicle middle ear, of hair, and of mammary glands. The classification of Reptilia is more unnatural than Amphibia because Crocodilians are more closely related to birds than other reptiles.
