	Talk:Reptile - Wikipedia, the free encyclopedia
		It is ridiculous because Saurischia says Reptilia and then Eoraptor says Archosauria.
		I believe Archosauria (modern birds and ancient dinosaurs) are considered a reptiles, but not in class Reptilia.
		This is based on discoveries by Chinese scientists in the last 20 years or so which planted birds squarely in the dinosauria suborder, combined with the wish to differentiate modern 'reptiles' and modern 'birds' into different classes.

	Palaeos Vertebrates 270.500 Archosauromorpha : Archosauria
		The recognized higher orders of Archosauria were Crocodilia, Pterosauria, Saurischia and Ornithischia (the monophyly of dinosaurs was not well established).
		Gauthier redefined the Archosauria as a crown group, the last common ancestor of birds and crocodiles and all of its descendants: crocs + rocs.
		Above Archosauria were the Erythrosuchidae and other forms previously referred to as "Proterosuchia." Gauthier used the term Archosauriformes to describe the clade uniting these forms with Archosauria.

	Classification of Reptilla
		The most striking characteristic of the Archosauria is the triradiate pelvis.
		In the archosaurians (Romer, fig 69, p 131.) the maxilla forms the anterior border and the lachrimal and jugal the posterior border of a large anteorbital fenestra.
		In the archosauria both the quadrate and quadratojugal bones form the jaw articulation, while in the lepidosaurs the quadrate forms the articulation.

	Palaeos Vertebrates 270.400 Archosauromorpha : Archosauriformes
		What is clear is that Euparkeria, Proterochampsidae, and Archosauria are a natural group and differ from other archosauriforms in a number of ways.
		GandW do not attempt a reconstruction, and the topographical relationships in the published figures suggest that it might be quite difficult to determine the original relationships inside the otic capsule.
		Discussion: If the tendency to gigantism was represented by Erythrosuchus, then the opposite, tendency towards the small light agile bird-like form was expressed by its cat-sized relative Euparkeria, which at 65 centimeters (26 inches) from snout to tail-tip was only an eighth the linear dimensions.

	Extinct Reptiles
		And there are 2 subclasses that have theDiapsid condition, that's the subclass Archosauria, which includes the crocodiles and thedinosaurs, and the subclass Lepidosauria, which includes only one living order Squamata, butthat's where we find all the rest of the living reptiles.
		And Archosauria includes the Thecodonts and the crocodiles and these 2 groups ofdinosaurs and the birds in a single group.
		And the birds are not in a separate class according tothat classification.

		You're argument for the clade Archosauria is at leat as good as any other I'm familiar with.
		No, you're right - but the definition of Archosauria is derived from the skull's features, not the limbs.
		Within the Archosauria, you would have subclades for dinosaurs and crocs.

		Most of the reptiles we think of as "dinosaurs" belonged to the Archosauria or "ruling reptile" subclass.
		However, at least 21 species and seven subspecies of Archosauria continue to live to this day, though some of them are endangered species.
		The largest living group of Archosauria is the crocodiles.

		The crocodiles are in theSubclass Archosauria and the rest of the living reptiles, thelizards and the snakes, are found in the Subclass Lepidosauria.There are other distinctive features which are used to distinguishbetween the Archosaurs and the Lepidosaurs that have a Diapsidcondition.
		Within theSubclass Archosauria, the most primitive group is the OrderThecodontia and they are the ancestors of all the others.
		Now the Subclass Archosauria is the one that includes theanimals that are properly called dinosaurs although you'll seepictures of the other Euryapsid type animals in the dinosaur books.Technically, the ones that are really dinosaurs belong in theSubclass Archosauria.

	Evolutionary Relationships of Archosaurs
		Those boxes which are a lighter blue (or lighter gray) are groups which do not belong to the Archosauria proper, but are close relatives.
		It is one of the closest known relatives to the true archosaurs, and looks a lot like what we think the first archosaur must have looked like.
		However, it is distinct enough that we can be confident that it is not the common ancestor of all archosaurs, and is just an early side branch outside of the Archosauria proper.

		The most plausible explanation for the extinction of the dinosaurs is the impact of a large extraterrestrial object in the Gulf of Mexico.
		All dinosaurs are diapsid archosaurian reptiles They are believed to have evolved from a group of reptiles known as the Ornithodira from the Archosauria.
		The saurischians have a pelvis with a forwardly directed pubis bone, where as the ornithischian pubis is parallel to the ischium.

		Birds and crocodylians are the only living representatives of the Archosauria, a once-diverse group that includes dinosaurs, pterosaurs, and other fossil forms exhibiting an enormous range of anatomical diversity.
		Because crown-group archosaurs offer examples of highly specialized respiratory systems serving both cold-blooded (ectothermic) and warm-blooded (endothermic) metabolic physiologies, the clade presents an unparalleled opportunity to examine evolutionary pathways in respiratory design and function.

		All dinosaurs belong to the class Reptilia, and the superorder Archosauria.
		Below Archosauria are two principal groups, the orders Saurischia and Ornithischia, which differ in their hip arrangement.
		Some scientists have argued that dinosaurs, which may have been warm-blooded, are so different from the other members of the class Reptilia that they deserve their own class: Dinosauria.

		It is thus surprising that so little is known about cephalic vasculature in Archosauria, a major amniote clade that today includes crocodilians and birds and in the past included non-avian dinosaurs, pterosaurs, and a variety of basal forms.
		No comparative studies exist on archosaur head vasculature and no previous attempt has been made to determine homologous structures and patterns across Archosauria.
		This interconnected network may further serve as a transport system for products produced in the Harderian gland and retina to the brain.

		The Crocodylia have undergone at least three separate episodes of adaptive radiation during their history.
		They are all members of the order Crocodylia - which in turn is a member of the superorder Archosauria.
		Fellow members of the Archosauria include the Saurischia (dinosaurs such as Diplodocus), Ornithischia (bird hipped dinosaurs such as Stegosaurus), the flying Pterosauria and the Thecodontia.

		If you examine the taxonomy for chicken (Gallus gallus) you will see the term "Aves" meaning birds, as in aviary, a place where birds are kept or consider the term aviation, refering to flying.
		We also see another term - "Archosauria", from high school biology we know that dinosaur means "terrible lizard", so "-sauria" is refering to a lizards.
		This classification fits with the notion that dinosaurs did not die out, that they evolved into modern day birds.
