Telmatosaurus (meaning "marsh lizard") is a genus of basal hadrosauriddinosaur from the Late Cretaceous. It was a relatively small hadrosaur, approximately five meters (16 ft) long, found in what is now Romania.
DiscoveryEdit
RestorationTelmatosaurus transsylvanicusvertebraeIn 1895 some peasants presented Ilona Nopcsa, the daughter of their lord, with a dinosaur skull they had found at theestate Săcele in the district Hunedoara(then named Hunyad) in Transylvania. Ilona had an elder brother, Ferenc orFranz Nopcsa von Felső-Szilvás who was inspired by the find to become a paleontology student at the University of Vienna. In 1899 Nopcsa named the skull Limnosaurus transsylvanicus. The generic name was derived from Greek λιμνή, limné, "swamp", a reference to the presumed swamp-dwelling habits of hadrosaurs. The specific namereferred to Transylvania.[1] Later Nopcsa discovered that the name Limnosaurushad already been used by Othniel Charles Marsh in 1872 for a crocodilian (later reclassified as Pristichampsus), so in 1903 Nopcsa renamed the genusTelmatosaurus. Telma again means "marsh".[2] In 1910 Barnum Brown, unaware of Nopcsa's replacement name, named the genusHecatasaurus,[3] but this is a junior objective synonym.The holotype, BMNH B.3386, was found in the Haţeg Basin in a layer of theSânpetru Formation dating from theMaastrichtian, about 68 million years old, at the time part of the Haţeg Island, one of the islands of the European Archipelago. It consists of a skull with lower jaws.In 1915 Nopcsa referred his species to the genus Orthomerus, as anOrthomerus transsylvanicus.[4]However, since the 1980s, Orthomerushas been considered a nomen dubium, leading to a revival of the nameTelmatosaurus. Fragmentary hadrosauroid material from Spain, France and Germany, that had been referred to Orthomerus, is now often assigned to Telmatosaurus, but an identity is hard to prove; the same is also true of many Romanian fragments and eggs.[5]
DescriptionEdit
The relatively small size ofTelmatosaurus with a length of five metres and a weight of half a tonne, has been explained as an instance of insular dwarfism.
