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 .
The study of birds is called ornithology. Birds are feathered theropod dinosaurs and constitute the only known living dinosaurs. Likewise, birds are considered reptiles in the modern cladistic sense of the term, and their closest living relatives are the crocodilians.
Unlike other species, turacos owe their color to a copper-based pigment called turacoverdin. The common grackle and many shimmering hummingbirds display iridescence like the way a prism splits ...
Pterodactyloidea (derived from the Greek words πτερόν (pterón, for usual ptéryx) "wing", and δάκτυλος (dáktylos) "finger") [1] is one of the two traditional suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles.
In phylogenetic systems, birds (descendants of traditional diapsid reptiles) are also considered to be members of this group. Some modern studies of reptile relationships have preferred to use the name "diapsid" to refer to the crown group of all modern diapsid reptiles but not their extinct relatives.
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.
Around 70 to 80 bird species will be renamed by the group, including birds in the United States and Canada. The group said it will remove the human names included in some of the bird nomenclature ...
