Editing Tetrapod (section)

===Mesozoic ===
The [[diapsid]] reptiles (a subgroup of the sauropsids) strongly diversified during the [[Triassic]], giving rise to the [[turtle]]s, [[Pseudosuchia|pseudosuchians]] (crocodilian ancestors), [[dinosaur]]s, [[Pterosaur|pterosaurs]], and [[lepidosaurs]], along with many other reptile groups on land and sea. Some of the new Triassic reptiles would not survive into the [[Jurassic]], but others would flourish during the Jurassic. [[Lizard|Lizards]], turtles, dinosaurs, pterosaurs, [[crocodylomorphs]], and [[Plesiosaur|plesiosaurs]] were particular beneficiaries of the Triassic-Jurassic transition. [[Bird]]s, a particular subset of [[Theropoda|theropod]] dinosaurs capable of flight via feathered wings, evolved in the Late Jurassic. In the [[Cretaceous]], [[snake]]s developed from lizards, [[Rhynchocephalia|rhynchocephalians]] (tuataras and kin) declined, and modern birds and crocodilians started to establish themselves.

Among the characteristic Paleozoic non-amniote tetrapods, few survived into the Mesozoic. [[Temnospondyl]]s briefly recovered in the Triassic, spawning the large aquatic [[Stereospondyli|stereospondyls]] and the small terrestrial lissamphibians (the earliest frogs, salamanders, and caecilians). However, stereospondyl diversity would crash at the end of the Triassic. By the Late Cretaceous, the only surviving amphibians were lissamphibians. Many groups of synapsids, such as [[anomodont]]s and [[therocephalia]]ns, that once comprised the dominant terrestrial fauna of the Permian, also became extinct during the Triassic. During the Jurassic, one synapsid group ([[Cynodontia]]) gave rise to the modern [[mammal]]s, which survived through the rest of the Mesozoic to later diversify during the Cenozoic. The [[Cretaceous-Paleogene extinction event]] at the end of the Mesozoic killed off many organisms, including all the non-avian dinosaurs and nearly all marine reptiles. Birds survived and diversified during the Cenozoic, similar to mammals.
