Telmatosaurus ( "swamp lizard" ) was a genus of dinosaur bird Beck from the group of Hadrosauridae. Fossil finds date from the Late Cretaceous ( Maastrichtian upper ) of Romania, France and Spain. It is only the type species T. transylvanicus scientifically described, which thus represents one of the rare Hadrosaurierarten in Europe.
Features
Telmatosaurus is known from five to ten skulls were found in pieces, and some contiguous parts of the Postcranialskeletts as vertebrae, sternum tissues and bones of the extremities.
He was a relatively small hadrosaur with about five meters in length. He had an elongated skull like Gryposaurus, but possessed contrary to this no " duckbill " but a long extended snout.
Because of Eifunden Telmatosaurus could have put 14 round eggs with a diameter of about 150 mm in four linear clusters of two to four eggs, with the individual filing sites were each placed about 0.5 m apart.
Localities
The type species Telmatosaurus transylvanicus was described by Franz Nopcsa of Felső - Szilvás as Limnosaurus transylvanicus in 1900. 1903 Nopcsa changed the generic name in the still valid name Telmatosaurus.
The first record came from the field in Sânpetru in Hunedoara County in western Romania. In the area in which it was the Cretaceous period to a Isel region, a number of other dinosaur skeletons have been discovered in numerous excavations, including the sauropod Magyarosaurus, the theropod Megalosaurus hungaricus, the Ankylar Struthiosaurus transsylvanicus and probably classify in the Iguanodontia Rhabdodon priscus.
Two other sites Telmatosaurus fossil - remains were found in France. In the Grès de Saint- Chinian in the department of Hérault Telmatosaurus was together with Megalosaurus pannoniensis ( Theropoda ), Hypselosaurus priscus ( Sauropoda ), Rhabdodon priscus and Rhodanossaurus found lugdunensis ( Ankylosauria ). Also in the Grès à Reptiles in the Var were Megalosaurus pannoniensis, Hypselosaurus priscus and Rhabdodon priscus, together with Telmatosaurus found it came up here the sauropod Titanosaurus indicus. Whether it is Telamtosaurus also for detections in the province of Lleida in northern Spain, is unclear; the remains were with Titanosaurus, Hypselosaurus and Rhabdodon priscus and another hadrosaur, who has since been assigned to the genus Orthomerus, also found here.
System
Telmatosaurus is considered as the primary mode of hadrosaur and has accordingly in addition to the provisions applicable to all hadrosaur features no derived characteristics of other Hadrosauriergruppen. Compared to the Gilmoreosaurus, which is considered as the second branch of the hadrosaur, he has bsp. yet the original relatively wide teeth without median crest, which also occurs in other Iguanodontia.
Within the genus, only the type species Telmatosaurus transylvanicus considered valid while the type described as T. cantabrigiensis Lydekker, 1888/Olshevsky, 1978 is considered a nomen dubium together with Trachodon cantabrigiensis. Dolloi T. Seeley, 1883 the type was Orthomerus dolloi (also a nomen dubium ) slammed.
