However, it is represented by only one living species: the tuatara (Sphenodon punctatus), a superficially lizard-like reptile native to New Zealand. [ 5 ] [ 6 ] Lepidosauria is a monophyletic group (i.e. a clade ), containing all descendants of the last common ancestor of squamates and rhynchocephalians. [ 7 ]
Obligate herbivory, on the other hand, has only evolved 10 times in living, non-liolaemid lizards (nearly 7,700 species). Though, one clade seems to be an exception to this pattern of infrequently developed herbivory. A 2004 study investigated a unique group of South American lizards called the Liolaemidae. The authors of this study found that ...
Lizards and snakes share a movable quadrate bone, distinguishing them from the rhynchocephalians, which have more rigid diapsid skulls. [5] Some lizards such as chameleons have prehensile tails, assisting them in climbing among vegetation. [6] As in other reptiles, the skin of lizards is covered in overlapping scales made of keratin. This ...
Lepidosauromorpha (in PhyloCode known as Pan-Lepidosauria [2] [3]) is a group of reptiles comprising all diapsids closer to lizards than to archosaurs (which include crocodiles and birds). The only living sub-group is the Lepidosauria , which contains two subdivisions, Squamata , which contains lizards and snakes , and Rhynchocephalia , the ...
Herpetology (from Greek ἑρπετόν herpetón, meaning "reptile" or "creeping animal") is a branch of zoology concerned with the study of amphibians (including frogs, salamanders, and caecilians (Gymnophiona)) and reptiles (including snakes, lizards, turtles, crocodilians, and tuataras).
Squamata (/ s k w æ ˈ m eɪ t ə /, Latin squamatus, 'scaly, having scales') is the largest order of reptiles, comprising lizards (including snakes).With over 12,162 species, [3] it is also the second-largest order of extant (living) vertebrates, after the perciform fish.
Sauropsida (Greek for "lizard faces") is a clade of amniotes, broadly equivalent to the class Reptilia, though typically used in a broader sense to also include extinct stem-group relatives of modern reptiles and birds (which, as theropod dinosaurs, are nested within reptiles as more closely related to crocodilians than to lizards or turtles).
