ET Harper discovered a love of dinosaurs as a child when she came across a strange looking bone buried in the garden. At first she thought it was small dinosaur bone but it turned out to be part of a chicken skeleton instead. When she found out chickens were distantly related to dinosaurs she thought all her Christmases had come at once and decided to become a professional dinosaur bone hunter. E.T Harper went on to study Palaeontology at university and she was so good at being a palaeontologist that they even made her a professor. Now she wants to share her dinosaur discoveries with little palaeontologists all over the world. This is E.T Harper's first series of books but she hopes to write many more. She also has her own tree house, just like Dylan.
