Lambeosaurus
Lambeosaurus is a genus of hadrosaurid dinosaur that lived about 75 million years ago, in the Late Cretaceous period of North America. This bipedalquadrupedal, herbivorous dinosaur is known for its distinctive hollow cranial crest, which in the best-known species resembled a hatchet. It is the only genus in the world that has not been named after a single individual, and it is the most common name for a species of dinosaur in the U.S. and Canada.
About Lambeosaurus in brief
Lambeosaurus is a genus of hadrosaurid dinosaur that lived about 75 million years ago, in the Late Cretaceous period of North America. This bipedalquadrupedal, herbivorous dinosaur is known for its distinctive hollow cranial crest, which in the best-known species resembled a hatchet. Material relevant to the genus was first named by Lawrence Lambe in 1902. The modern name was coined in 1923 by William Parks, in honour of Lambe, based on better preserved specimens. Several possible species have been named, from Canada, the United States, and Mexico, but only the two Canadian species are currently recognized as valid. Currently, the various skulls assigned to the type species L. lambei are interpreted as showing age differences and sexual dimorphism. Lambeosaurus was closely related to the better known Corythosaurus, which is found in slightly older rocks, as well as the less well-known genera Hypacrosaurus and Olorotitan. All had unusual crests, which are now generally assumed to have served social functions like noisemaking and recognition. It has at times been considered synonymous with Jaxartia aralensis, or aralosaurus. The only complete skeleton of the only species of the new genus Kazakosaurines isn’t the only one that has been named. It was named by A. Kdestdestsky Rozhsky in 1968, and Procheneosaurus received official approval from the ICZN as a conserved name in 1975.
This usage was generally followed until Peter Dodson proposed all three species were actually juveniles of Lam beosaurus. In 1975, all three were actually made convincingly the new species of P. praeceps, with P. rozhsky serving as the type. The name Prochenosaurus was granted, and the species is now considered to be the only valid species of lambeosaurus. It is the only genus in the world that has not been named after a single individual, and it is the most common name for a species of dinosaur in the U.S. and Canada. The genus has a complicated taxonomic history, in part because small-bodied crestedHadrosaurids now recognized as juveniles were once thought to belong to their own genera and species. In 1920, William Diller Matthew used the name ProCheneosaurus in a brief mention of a skeleton at the American Museum of Natural History, from the Dinosaur Park Formation. In 1942 he and Wright transferred the Tetragonosaurus species and tentatively, to Procheeosaurus, with T. altidens, to be used as type species. The use of Tetragonsosaurus was rejected by Richard Swann Lull in favor of Procheteosaurus. A nearly complete skeleton from Kazakhstan is known from a nearly complete skeleton, the snout and end of the tail, which was named A. Rozhky in 1968.
