Dino mad Charlie spots mistake on dinosaur exhibition at museum

10 years old Charlie definitely knows a thing or two about dinosaurs.

So much so, that when he went on a visit to the Natural History Museum in London, he discovered that they had made a mistake in one of their exhibitions.

Luckily he pointed it out and they were very grateful for his help.
