Did you know?

Even though Brachiosaurus had only 50 teeth or less, it could eat 100 to 400 kilograms (220 to 881 pounds) of plants every day! Its long neck helped it reach the highest leaves on trees, where the best food was.

Katia wrote ten “did you know” facts for the end of Dinosaurs Are Back, one for each dinosaur Spike meets. This is the Brachiosaurus one, and the film next to it reads it aloud.

In the story

Spike meets the Brachiosaurus

I had to cross the lake, and I can't swim. Idea alert! She gave me a warm smile and showed me a secret path, where lots of Brachiosauruses were drinking.

I hopped from one back to the next, about twenty of them, all the way to the other side!
