Mantellisaurus
The holotype fossil, NHMUK PV R5764, was originally discovered by Reginald Walter Hooley in 1914 in the upper Vectis Formation of southern England and reported upon in 1917.The Maidstone slab was utilized in the first skeletal reconstructions and artistic renderings of Iguanodon, but due to its incompleteness, Mantell made some mistakes, the most famous of which was the placement of what he thought was a horn on the nose.[3] Shortly after the discovery, tension began to build between Mantell and Richard Owen, an ambitious scientist with much better funding and society connections in the turbulent worlds of Reform Act–era British politics and science.[4] With Benjamin Waterhouse Hawkins, Owen had nearly two dozen lifesize sculptures of various prehistoric animals built out of concrete sculpted over a steel and brick framework; two Mantellodon, one standing and one resting on its belly, were included.[14][15] Specimen IRSNB 1551 from the Sainte-Barbe Clays, Belgium, became the second mounted skeleton of a non-avian dinosaur made primarily out of actual bone when put on display by Louis Dollo in 1884.In 2010, Kenneth Carpenter and Yusuke Ishida synonymized Dollodon bampingi with Iguanodon seelyi, a species based on BMNH R 28685 from Wessex Formation, England.[18][19][20] In 1971, a fossiliferous karstic sinkhole clay deposit was found at a quarry just south-west of the village of Nehden near Brilon in Sauerland, Germany containing numerous disarticulated iguanodontid remains predominantly of Mantellisaurus with lesser quantities of Iguanodon, alongside other fragmentary dinosaur and crocodylian material.[26] Uteodon aphanoecetes Hippodraco scutodens Theiophytalia kerri Iguanacolossus fortis Lanzhousaurus magnidens Kukufeldia tilgatensis Barilium dawsoni Iguanodon bernissartensis Mantellisaurus atherfieldensis Other hadrosauroids
