"Regnosaurus" (meaning "Sussex lizard") is a genus of herbivorous stegosaurian dinosaur that lived during the Early Cretaceous Period in what is now England.

Discovery and species

The fossil remains were found near Cuckfield in Sussex, and initially thought to be from "Iguanodon". However, Mantellreviewed it and felt it to be of a different creature, coining the name "Regnosaurus" in 1848. [cite book|title=The Dinosaur Hunters|year=2000|author=Deborah Cadbury|publisher=Fourth Estate, London|id=ISBN 1-85702-959-3] It is known only from a right mandibular (lower jaw) fragment. A fossil pubis was also recovered on the Isle of Wight.

Recent research by Barret and Upchurch in 1995 [cite journal|author=Barret PM & Upchurch P|year=1995|title="Regnosaurus northamptoni", a stegosaurian dinosaur from the Lower Cretaceous of Southern England|journal=Geological Magazine|volume=132|pages=213–222] suggests that it is a stegosaur similar to "Huayangosaurus", as the jaws are very similar. A "nomen dubium", the type species is "Regnosaurus northamptoni".
