Reptiles, on the other hand, are shown only in list format in a chapter titled "Miscellaneous", where the other non-bird animals (and many non-animals) are listed. Shearer and Shearer consider the state reptiles to be part of a "last thirty years" phenomenon (written in 2003) that includes such particular items as a state's "official beverage ...
Avemetatarsalia (meaning "bird metatarsals") is a clade of diapsid reptiles containing all archosaurs more closely related to birds than to crocodilians. [2] The two most successful groups of avemetatarsalians were the dinosaurs and pterosaurs.
Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology.
Ohio's state bird, the cardinal (C. cardinalis), was designated the state bird by the General Assembly in 1933. [19] It was then listed as effective in the Ohio Revised Code in 1953. [13] State animal: State animal – white-tailed deer: The white-tailed deer (O. virginianus) became the official state animal in 1988. [13] State reptile
Purely in the context of modern taxa, Lepidosauria can be considered the sister taxon to Archelosauria, which includes Testudines (turtles), Aves (birds) and Crocodilia (crocodilians). Lepidosauria is encompassed by Lepidosauromorpha, a broader group defined as all reptiles (living or extinct) closer to lepidosaurs than to archosaurs.
Cladistically birds are considered reptiles, but according to traditional taxonomy they are listed separately. Saurischia includes extinct relatives of birds, the "lizard hipped" dinosaurs. [81] [82] See List of bird genera.
Synapsida [a] is a diverse group of tetrapod vertebrates that includes all mammals and their extinct relatives. It is one of the two major clades of the group Amniota, the other being the more diverse group Sauropsida (which includes all extant reptiles and birds).
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).
