A Dinosaur’s Life
The Story of Zelda and Zara

What was life really like for a dinosaur, 75 million years ago?

At the Natural History Museum in Oslo, you can visit the skeletons of two duck-billed dinaosaurs – an adult and a youngster, Zelda and Zara.

In this book, you’ll discover how these two, and many other dinosaurs, lived together. How did such enormous creatures manage to lay eggs? Why did so many dinosaurs have huge horns or spikes on their bodies? And did some dinosaurs actually live in herds?

Paleontogogist Jørn H. Hurum, author Torstein Helleve, and illustrator Esther van Hulsen bring the tale of Zelda and Zara to life – sharing fascinating and surprising facts about excavations, fossils, and dinosaurs.
