My son’s favourite dinosaur is the T. rex, and my daughter’s is the triceratops. She does a very good triceratops charge! But nobody alive has ever seen a living dinosaur, so how can we be so sure they were real?

I’ve got three possible answers to that question: one is true, one is made up, and one sounds true but isn’t. Can you guess which is which? Listen out for today’s Wonder Words too.

Wonder Kids will find out how we know dinosaurs were real, how fossils are made, and how scientists work out how old they are.

What’s your favourite dinosaur, Wonder Kids? Have it ready and let’s dig in together.
