In the 1800’s, Mary Anning was known as the best fossil hunter in England. She made many great discoveries, including dinosaur poop. With help from our friend Kidosaurus and children’s science historian Melanie Keene, we dig into Mary Anning’s story and her place in the history of women in science. Check out the blog about this episode on our website, sciencepodcastforkids.com. 

We have some exciting changes to share with you at the beginning of this episode!  Plus, Part 1 of our favorite-ever two part series about dinosaur poop!
