Who Discovered the Iguanodon?

Who Discovered the Iguanodon?

If you remember our post last month about [Mary Anning], today’s post describes the discovery by a woman who lived at the same time and in the same country – Mary Ann Woodhouse.

Mary Ann was born in 1799 in England. She married a doctor (Gideon Mantell) in her early 20s and took his last name, becoming Mary Ann Mantell. She would accompany him to visit patients. On one of these occasions, she was waiting outside and went to examine the gravel on a recently paved road. Among the gravel she found large teeth (but see note below)!

She showed them to Gideon, who was also an amateur paleontologist. Realizing that the teeth belonged to something new, he consulted well known paleontologists at the time to discover that these teeth belonged to a large, ancient herbivore. He named the dinosaur Iguanodon (for “Iguana tooth”) and went on to publish a book about this and other fossils of the area with the help of Mary Ann who illustrated all of the fossils.

Note: Even though Mary Ann did make the illustrations for the book, her discovery of the teeth is debated. Once I do more research, I’ll edit this post accordingly.
