- Neovenator was a Theropod Dinosaur. It was a member of the Allosaur family.
- 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 in length, and was of a gracile build. It lived during the Barremian stage of the Cretaceous Period.
- 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 (1989) 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.
- L'unique espèce Neovenator salerii mesurait environ 9 ou 10 mètres de long pour 4 mètres de haut et un poids approximatif de 2,2 tonnes. Sa taille était supérieure à la plupart des autres allosauroidés.
- Neovenator measured approximately 7.6 meters (25 feet) in length, and was of a gracile build, weighing 1000–2000 kg.[1] Specimen MIWG 4199 indicates an individual with a possible length of about ten meters (33 feet), but it only consists of a toe phalanx.[2]

- L'unique espèce Neovenator salerii mesurait environ 9 ou 10 mètres de long pour 4 mètres de haut et un poids approximatif de 2,2 tonnes. Sa taille était supérieure à la plupart des autres allosauroidés. Elle possédait une petite crête sur la tête, caractéristique de la plupart des néovenatoridés.Neovenator est parfois classé en tant que carcharodontosauridé primitif. On note également une proche parenté avec les sinraptoridés.

- 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 in length, and was of a gracile build. It lived during the Barremian stage of the Cretaceous Period.
- 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 (1989) 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.
- Neovenator measured approximately 7.6 meters (25 feet) in length, and was of a gracile build, weighing 1000–2000 kg.[1] Specimen MIWG 4199 indicates an individual with a possible length of about ten meters (33 feet), but it only consists of a toe phalanx.[2] The various scientific descriptions of Neovenator have indicated some distinguishing traits. The nostril is twice as long as it is high. The praemaxilla in the snout bears five teeth. The maxilla is pierced by a large maxillary fenestra, the diameter of which equals a sixth of the length of the tooth row. The tooth crown equals a quarter of the tooth length, thus including the root. The toe claws have a groove on top.[3] Both praemaxillae are connected by an extra pen-in-socket connection.[4] The front joint surface of the intercentrum of the axis, the second neck vertebra, is transversely widened. The odontoid process of the axis has small openings along the side edge of the front facet. The neural process of the axis has a single small opening in the side. The rear neck vertebrae are fused with their neck ribs. On the eighth and ninth neck vertebrae, at the parapophysis, the lower rib joint facet, the internal camellate structure of the bone is visible. At the front neck vertebrae the undersides are formed as sharp keels which are not inset from the lateral sides. At the front back vertebrae, the hypapophyses, the lower swellings of the front facet edges, are formed like low mounds. On the rear back vertebrae the facets of the joint processes are continued sideways as curved flanges. The shoulder joint is wider transversely than long, measured from the front to the rear. The notch on the underside of the front blade of the ilium has a shelf at the inner side. The "feet" of the ischia are connected at their fronts but diverge at their rears. The head of the thighbone is obliquely directed to the front, to above and to the inside. On the thighbone the lesser trochanter has a robust ridge on its outer side. On the thighbone the fourth trochanter has a depression in the form of a thumbprint located to the outside of its upper limit. The front underside of the thighbone is nearly flat, only showing a short vertical groove between the lower condyles. The lower shinbone shows an oval rough area at the inner side. The top of the outer malleolus of the shinbone is pinched from the front to the rear. The outer front bulge of the top surface of the shinbone has a spur pointing to below. In the foot, the outer side of the second metatarsal has a hollow surface to contact the third metatarsal. Several traits that once were thought to be unique or apomorphic for Neovenator, subsequent research showed to have been shared by other theropods. The nostrils are large but not uncommonly so. Having pneumatised rear back vertebrae is normal for carcharodontosaurids. Elevated paired nasal crests are shared with Allosaurus. Denticles continuing over the tooth apex are today known from other species.[5] In 2015, it was reported that the front of the snout of Neovenator contains a complex system of neurovascular canals, functioning as sensory organs. This trait is also known from Spinosauridae and was there explained as an adaptation for searching prey in water. It was doubted however, whether Neovenator used its system for the same purpose.[6]
