The Rhamphorhynchoidea forms one of the two suborders of pterosaurs and represent a grade of primitive members of this group of flying reptiles. Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Reptiles, or members of the class Reptilia are air-breathing Cold-blooded Vertebrates that have skin covered in scales as opposed to hair or feathers For other meanings see Pterodactyl (disambiguation. Pterosaurs (ˈtɛrəsɔr from the Greek πτερόσαυρος pterosauros In Phylogenetics, a group of organisms is said to be paraphyletic if the group contains its most recent common ancestor but does not contain all In Biological classification, family ( Latin Anurognathids were a group of small Pterosaurs, mostly tailess that lived worldwide during the Jurassic Period.

Pterosaurs (ˈtɛrəsɔr from the Greek πτερόσαυρος pterosauros Reptiles, or members of the class Reptilia are air-breathing Cold-blooded Vertebrates that have skin covered in scales as opposed to hair or feathers This suborder is paraphyletic in relation to the Pterodactyloidea, which arose from within the Ramphorhynchoidea, not from a more distant common ancestor. In Phylogenetics, a group of organisms is said to be paraphyletic if the group contains its most recent common ancestor but does not contain all Pterodactyloidea (derived from the Greek Words πτερόν ( pterón, for usual ptéryx) "wing" and δάκτυλος Because it is not a completely natural grouping, Rhamphorhynchoidea is not used as a formal group in most scientific literature, though some pterosaur scientists continue to use it as an informal grouping in popular works, such as The Pterosaurs: From Deep Time by David Unwin, and in some formal studies. [1][2] Ramphorhynchoids were the first pterosaurs to have appeared, in the late Triassic Period. The Triassic is a geologic period and system that extends from about 251 to 199 Ma (million years ago Unlike their descendants the pterodactyloids, most rhamphorhynchoids had teeth and long tails, and most species lacked a bony crest, though several are known to have crests formed from soft tissue like keratin. Keratins are a family of fibrous structural proteins; tough and insoluble they form the hard but nonmineralized structures found in Reptiles Birds They were generally small, and disappeared at the end of the Jurassic Period. The Jurassic is a geologic period and system that extends from about Ma (million years ago to Ma that is from the end of the Triassic to the beginning

This list of pterosaur classifications entails the various schemes used to classify Pterosaurs throughout the years and varying views of these Animals Classic In phylogenetic taxonomy, "rhamphorhynchoids" consist of all basal (primitive) pterosaurs that do not belong to the clade Pterodactyloidea. In Phylogenetics, a basal Clade is the earliest clade to branch in a larger clade it appears at the base of a cladogram Pterodactyloidea (derived from the Greek Words πτερόν ( pterón, for usual ptéryx) "wing" and δάκτυλος
