Holly added to Jack’s work by studying the histology of fifty individual Maiasaura and recording the life story of each individual dinosaur from the clues in its bone microstructure.

Jack introduced Holly to Maiasaura by showing her fossils that belong to tiny dinosaur hatchlings, twenty-foot-long adults, and everything in between. At that time, Jack had already learned a lot about Maiasaura, especially about dinosaur babies.

Like Lily, as a Young Girl, Holly loved dinosaurs…

For as long as she can remember Holly has loved dinosaurs. Her parents have a picture of her at two and a half years old with a spoon and beach bucket, digging for fossils in the back yard. She had a lot of dino toys from an early age too.

Holly watched many documentaries and read every book about dinosaurs that she could find. Discovery Channel was a favorite, and she always watched shows about Jack and dinosaurs. Holly feels that she became an early expert on identifying what was scientifically incorrect in books because she was watching and absorbing ‘the latest dinosaur science’ on television!

Studying under Jack, who “taught me how to think and who opened doors for me by pushing me forward and suggesting that I try this or try that,” led to Holly’s love of being a Paleo Scientist!

Holly’s Thoughts on Jack’s Dino Book for Kids!


“I love it and wish there had been this kind of story around when I was little.”

“Maia is a nice size for a dinosaur and relatable to kids. It is small and then it grows big in stages – just like kids!”

“We know so much about this dinosaur and so Maia is a very good teaching tool about dinosaur nurturing family behavior.”

“Jack Horner ranks among the greatest dinosaur paleontologists of all time. He has also played an outsized role in popularizing the new science of dinosaurs, forever changing the way we look at these amazing ancient animals and inspiring many to pursue fossil-hunting careers.”

“With Lily and Maia, Horner taps into this vast experience to create a wonderful children’s book. Readers will head out into the field in search of dinosaur remains, and even set off on some time-traveling adventures! For the legions of young dinosaur lovers out there, here is a story guaranteed to spark imaginations!”

“Lily and Maia is a delightful introduction to paleontology for kids. Many children are aspiring fossil-hunters and will likely be inspired by this story of a young student making discoveries in the field. I appreciate that the book introduces tools and practices of science, including making and recording observations and using evidence to draw conclusions.

The young child in the story may even have made an observation that upends an argument made by an established scientist – a wonderful notion that will keep kids on their toes. The author’s clever device of allowing Lily to dream that she meets an actual dinosaur brings the story to life. I highly recommend this book for all families and schools with curious kids.”
