== History of discovery == The holotype specimen, MIWG 6344, was discovered along with the holotype of Neovenator during the summer of 1978, when a storm made part of the Grange Chine collapse. Rocks containing fossils fell to the beach of Brighstone Bay on the southwestern coast of the Isle of Wight. The rocks were part of the plant debris bed L9 within the variegated clays and marls of the Wessex Formation dating from the Barremian stage of the Early Cretaceous, about 125 million years ago. They were first collected by the Henwood family and shortly afterwards by geology student David Richards. Richards sent the remains to the Museum of Isle of Wight Geology and the Natural History Museum, London. In the latter institution paleontologist Alan Jack Charig determined that the bones belonged to two kinds of animal: Iguanodon and what would later become Neovenator. The "Iguanodon", later referred to Mantellisaurus, at first generated the most interest and in the early 1980s a team was sent by the NHM to secure more of its bones. Amateur paleontologists Keith and Jenny Simmonds assisted in collecting remains.
