Owenodon hoggii

Originally described by Richard Owen in 1874, Owenodon went by the name of Iguanodon hoggii for well over a century, during which time it was thought to be the oldest known species of Iguanodon. That was a brave assumption, bearing in mind its remains amounted to a battered jawbone, most of which was still stuck in a slab of rock. Still, it was eventually acid-bathed from its bone-obscuring matrix in the mid-seventies but wasn't seriously scrutinized until 2002, which is when David Norman and Paul Barrett transferred it to Camptosaurus along with a thigh from Dorset and a partial hindlimb (with a large callus from a healed shin fracture) from Yorkshire.

In 2009, Peter Galton inspected said remains and politely reasoned that the Dorkshire fossils were from two different critters, when a lesser man would have chastised Norman and Barrett for thinking that three sets of bones with nothing in common, physically or otherwise, belonged together. Furthermore, he argued that the original jaw was neither from a species of Iguanodon nor of Camptosaurus on account of its depth, arched tooth row and form of its teeth. Thus, Owenodon was added to the roll call of fearfully great lizards, but retained the epithet hoggii in honor of its discoverer.
(Hogg's Owen tooth)Etymology
Owenodon is combines "Owen" (for paleontologist Sir Richard Owen who first described its remains) and the Greek "odon" (tooth).
The species epithet, hoggii, honors A.J. Hogg.
Discovery
The remains of Owenodon (originally known as Iguanodon hoggi) were discovered in the Worbarrow Tout Member of the Lulworth Formation, Durlston Bay, Swanage, Dorset, England, by A.J. Hogg in 1860.
The holotype (NHM R2998) is an almost complete right dentary (the tooth-bearing bone of the lower jaw) with most of the teeth where they should be.
