Echinodon

Echinodon is a genus of heterodontosaurid dinosaur that lived during the earliest Cretaceous of southern England and possibly western France in the Berriasian epoch. The first specimens were jaw bones named Echinodon becklesii by Sir Richard Owen in 1861, and since their original description only additional teeth have been discovered. The specific name honours collector Samuel Beckles who discovered the material of Echinodon and many other taxa from across England, while the genus name translates as “prickly tooth” in reference to the dental anatomy of the taxon.

Originally, Echinodon was considered to be a type of herbivorous lizard, though this was quickly revised to an intermediate ornithischian. It was referred to the clade Stegosauria based on general dental anatomy and incorrectly referred armour that was later identified as a turtle’s.
