	Sphenodontia - Wikipedia, the free encyclopedia
		Sphenodontia is an order of lizard-like reptiles that includes only one living genus, the tuatara (Sphenodon).
		Despite its current lack of diversity, the Sphenodontia at one time included a wide array of genera in several families, and represents a lineage stretching back to the Mesozoic Era.
		Sphenodontia, once a wastebin taxon containing a diverse array of unrelated reptiles (notably the rhynchosaurs), today consists of three families--The possibly paraphyletic Gephyrosauridae, the Pleurosauridae, and the Sphenodontidae.

	Tuatara - Wikipedia, the free encyclopedia
		There are two extant species of tuatara: Sphenodon punctatus and the much rarer Sphenodon guntheri, or Brothers Island tuatara, which is confined to The Brothers Islands in Cook Strait.
		on Sphenodontia has shown that this group has undergone a variety of changes throughout the Mesozoic.

	NZ Herpetofauna
		New Zealand is justifiably renowned as the home of the so-called ‘living fossil’, the tuatara (Sphenodon) – sole survivor of the reptilian order Sphenodontia.
		What is not so well known is that New Zealand has a surprisingly rich amphibian and reptile fauna including some of the world’s most anatomically primitive frogs and geckos.
		Because the factors which have brought about this situation are still present the continued survival of many reptile and amphibian populations will only be possible if conservation measures are implemented.

	Tuatara
		Sphenodontia was proposed by Williston in 1925, and thus has priority use over the similarly named Sphenodontida, which was proposed by Estes in 1983 (Fraser and Sues, 1994).
		However, recent taxonomic work on Sphenodontia (Wu, 1994) has shown that this group has undergone a variety of changes throughout the Mesozoic.

		Also notice that having a hard shell is not a prerequisite for membership in this group.
		Lepidosauria: Sphenodontia, Squamata I. You will notice that the diapsids from the phylogeny on the the first page have split into two groups: the Lepidosauria and the Archosauria.
		Sphenodontia are represented by tuataras, animals found in the cold islands and waters off the coast of New Zealand.

		Isolated or declining species have been the subject of such studies less frequently.
		We report such a case study here, that of Mâori TEK of tuatara, the last representatives of the reptilian Order Sphenodontia.
		Mâori are indigenous to Aotearoa (New Zealand) having settled it 700 to 1000 years ago.

		Lizard skulls at the University of Texas CT scanning lab, with many more ready to browse.
		Sphenodontia are a sister group of the Squamata but include only one family with one living form, the tuatara Sphenodon.
		Euparkeria could have been the ancestor of both pterosaurs and dinosaurs later in the Triassic.

	Tuatara
		The similarity in morphology to other Sphenodontians from 200 million years ago suggests a evolutionary conserved species.
		Although the sole representative of the Sphenodontia Order it is known that the Sphenodontians were quite speciose around 200 million years ago.
		Initially thought of as a lizard, there are enough differences to term the tuatara a lizard-like reptile.

		It is only found in New Zealand and has three eyes.

		Tuatara (shown right) are rare and are in danger of becoming extinct due to relatively new infestations of rats.
		They are the only remaining species of the Order Sphenodontia from the dinosaur age about 200 million years ago.

	AWC: summer project report
		The remaining members of the genus have been genetically grouped within the subfamily Amblyomma, and without available data the Tuatara tick, Aponomma sphenodonti was also kept by default within Amblyomma.
		Tuatara; Sphenodon punctatus (Cook Straight Tuatara), sub-species Sphenodon punctatus punctatus (Northern Tuatara), and Sphenodon guntheri (Brothers Island) are the sole remaining representatives of an ancient order of reptiles, Rhynchocephalia, or Sphenodontia (Hay, Dougherty, Cree and Maxon 2003).
		Primarily this project aimed to provide a sound basis of where the Tuatara tick A.

	TAPHONOMY OF THE AARON SCOTT QUARRY, UTAH (MORRISON FORMATION, JURASSIC) (Site not responding. Last check: 2007-10-29)
		The Aaron Scott Quarry is an important accumulation of Jurassic fauna within the Morrison Formation in central Utah.
		Although the Morrison Formation is well known for its dinosaur fauna, having produced type specimens of several well known species, the Aaron Scott Quarry hosts, with the dinosaurs, an abundance of microfauna including crocodiles, sphenodontia, and possibly mammals.
		Dinosaur specimens are dominated by Diplodocus and Apatosaurus but also include Allosaurus, Ceratosaurus and Othneilla.

		Lizards are eaten by cats, ferrets, stoats, weasels, hedgehogs, rats, mice, and even some birds like magpies, kingfishers and flbirds.
		Although the tuatara looks like a lizard, it is actually the last remaining member of an ancient group of reptiles - Sphenodontia - that was around during the time of the dinosaur (over 200 million years ago).
