	Archosauria - Wikipedia NL
		De Archosauria waren de 'heersende reptielen' die een groot deel van het Mesozoicum ( Trias, Jura, Krijt) beheerst hebben.
		Zij behoorden tot de groep van de Archosauriformes, een onderverdeling van de Archosauromorpha.
		Na de uitstervingsgolf aan het eind van het Perm waaieren de Archosauromorpha snel uit in een grote verscheidenheid van vormen.

	Diapsid Phylogeny
		He found that if turtles and ichthyosaurs were included in his matrix, ichthyosaurs were the sister-group of sauropterygians, and this large clade of aquatic diapsids was close to the base of Archosauromorpha, while turtles appeared to be lepidosauromorphs.
		Finally, Merck (1997) suggests that ichthyosaurs are the sister-group of sauropterygians, and that this clade is part of Archosauromorpha.
		The conflicting results obtained from various authors, and sometimes, by a single author (or group of authors) using different taxa suggest that more work is needed to assess the affinities of ichthyosaurs, sauropterygians, and turtles.

		The Ornithodira, gave rise to the Dinosauria and to the Pterosauria.
		Interestingly, another line of species derived from the Archosaurs, the Crurotarsi, gave rise to the only other extant group of Archosauromorpha, the Crocodylomorpha.
		The crocodiles evolved at about the same sort of time as the first Dinosaurs.

	Archosauria: More on Morphology
		The archosaurs are characterized by numerous synapomorphies that lend strong support to the hypothesis that they form a monophyletic group (clade) exclusive of other Reptilia.
		First of all, the "stem archosaurs" (properly termed Archosauromorpha), including Champsosauridae and Euparkeria, have a calcaneal tuber.
		This is a bony process projecting posteriorly from the ankle joint that serves as an attachment point for some of the lower leg flexor muscles.

	Another AiG lie - TheologyWeb Campus
		The evolutionary phylogenic tree of life contains the following two distinct groups: the Lepidosauromorpha (comprised of lizards and snakes) and the Archosauromorpha (which contains crocodiles, birds, and dinosaurs).
		Based on this phylogenetic tree, one can make the prediction that the genetic sequences responsible for the same proteins in birds, crocodiles, and snakes will be more similar between birds and crocodiles than between snakes and crocodiles.
		There may have been an unintentional faulty deduction from it (that's if the abusive and scientifically illiterate BA is right), but even that presupposes certain fairly recent phylogenetic schemes that place the birds in the Archosauromorpha as opposed to separating the birds and reptiles.

		And yet, it has been evident since 1861 that birds are derived from ancestral stock somewhere within Archosauromorpha, and are therefore nested within Reptilia.
		Under a typological system such as Linne used, however, a form like Archaeopteryx cannot be both reptile and bird; it can only be one or the other.
		Including birds and defining the avian lineage such that it is nested within Archosauromorpha and Reptilia as a whole can resurrect Reptilia as a valid taxonomic category.

		Archosauromorpha includes all sauropsids with four-chambered hearts, an evolutionary innovation that permitted them higher activity levels and terrestrial dominance throughout the Mesozoic Era.
		The forms shown here were once all included in Archosauria in the "grab-bag" taxon "Thecodontia" -- any archosaur that wasn't a crocodylian, a pterosaur, or a dinosaur.

		Let's do a survey, ask the next ten people you meet and see if they can define "dinosaur".
		No, they and other protorosaurs are classified away from the Sauropterygian stock, and into the Archosauromorpha.
		Where the nothosaurs came from is still something of a mystery, but it appears any similarity between them and to Dinocephs is convergent.

		In recent years the hypothesis that pterosaurs were the major sister-group of dinosaurs and a closely-linked hypothesis that pterosaurs evolved flight from the ground up have gained general acceptance.
		A cladistic analysis of the Archosauromorpha using characters presented by previous workers results in a single most parsimonious tree with the Pterosauria as the major sister-group of the Dinosauria.
		However, that sister-group relationship is supported only by a suite of hindlimb characters that are correlated with bipedal digitigrade locomotion in dinosaurs.

		The Diapsida split into several now extinct groups and eventually split again into the Lepidosauromorpha and Archosauromorpha.
		The Lepidosauromorpha is comprised of lizards, snakes and their extinct relatives, while the Archosauromorpha is comprised of the crocodiles, pterosaurs, and dinosaurs (including birds).
		The ascendancy of dinosaurs on land transpired rather rapidly some 215 million years ago, before the close of the Triassic.
