I found this tooth while searching my collection of Sussex Wealden, Hastings bone bed. Similar to the small size ornithopod dinosaur Hypsilophodon premaxilla teeth, but this species can be ruled out. It is more similar to the small ornithopod Echinodon, Purbeck beds, Dorset premaxilla teeth. The crown is smooth and asymmetrical. The root curls up at the end, similar to some Iguanodon teeth in original early illustrations of the Iguanodon species. I prepped the tooth out completely from the matrix. Tooth is very small being 5mm long. Can anyone help me with identification of this tooth?
