Neovenator ("new hunter") is a genus of allosauroid dinosaur. Since its discovery on the Isle of Wight, UK, it has become one of the best-known large carnivorous dinosaurs in Europe. Neovenator was at first considered possibly a new species of Megalosaurus. It measured approximately 7.5 meters (24.5 feet) in length, and was of a gracile build, weighting 1000-2000 kg. Some fossils indicate a possible length of about 10 meters (33 feet), but these fossils are very fragmentary. It lived during the Barremian stage (Early Cretaceous), about 125 million years ago.
Discovery and speciesEdit
The first bones of the type species were discovered in 1978, in a plant debris bed within the variagated clays and marls of the Wessex Formation on the southwest coast of the Isle of Wight. It was much later (1996) that more bones from this specimen were found. Excavations undertaken by Dr Steve Hutt and his team have so far revealed approximately 70% of the skeleton.
At the time that it was described, by Steve Hutt, Martill and Barker in 1996, it was considered the only known allosaurid in Europe. However, further studies suggested it had more in common with the advanced carcharodontosaurid group of allosaurs, and several studies including a detailed examination of the species by Benson, Carrano and Brusatte in 2010 showed that it is in fact closely related to the Carcharodontosauridae (in a group called Carcharodontosauria), but is actually closer to the Megaraptorans, together with them forming the family Neovenatoridae.
The holoteype of Neovenator salerii had many pathologies. The authors of the genus list them as "midcaudal vertebrae fusions, healed fractures of mid-caudal vertebra transverse processes; osteophytes affecting pedal phalanges, healed gastralia rib fractures, some forming false joints... [and] scapula fracture."
