    • Estimated to be about 25 ft (7.6 m) lengthy
    • Weighed about 2,200 to 4,400 lb (1,000 to 2,000 kg)
    • Had a gracile construct

    • Might have had a “delicate face”, as described by Chris Barker and others in 2017
    • Had a posh system of neurovascular canals, which labored like sensory organs (related trait to Spinosauridae, although it in all probability didn’t search for prey within the water)

    • Might also have been used for courtship or nurturing its younger (like many fashionable crocodilians)
    • Want extra evaluation to grasp the facial sensitivity
    • Fossils present in 1978, when a storm precipitated rocks to fall to the seashore on the Isle of Wight
    • These rocks have been collected by the Henwood household after which geology pupil David Richards, who despatched them to the Museum of Isle Wight Geology and the British Museum of Pure Historical past, the place Alan Jack Charig discovered the fossils belonged to Iguanodon and a few sort of theropod

    • Genus identify means “new hunter”
    • Species identify in honor of the Salero household, who personal the location the place it was discovered (too many individuals had discovered fossils, so that they didn’t need to identify only one particular person because the one who found the dinosaur)
    • Steve Brusatte, Roger Benson, and Steve Hutt redescribed Neovenator in 2008
    • Enamel that look the identical because the holotype of Neovenator have been present in France in 2014
    • Holotype had pathologies (healed fractures, vertebrae fusions, and many others.)
    • Lived amongst fish, amphibians, lizards, pterosaurs, and Mantellisaurus

    Enjoyable Truth:
    Herbivores typically specialize on particular vegetation. For instance diplodocids undoubtedly couldn’t eat grass. It hadn’t developed, and their enamel could be fairly ineffective for biting it.
