Kron and Aladar are Iguanodon, a herbivorous dinosaur that lived around 125 million years ago during the Early Cretaceous. They grew about 8 to 10 meters long (26 to 33 feet) and are recognized by their beaked snouts and thumb spikes, which were likely used for defense. The movie mixes animals that never lived at the same time. Carnotaurus, for example, lived much later, around 70 million years ago in South America, so it would never have encountered Iguanodon.

Surrounded by some of the best Iguanodon fossils in the world. 😍 If you know your palaeontology lore, these fossils are from the famed 1878 discovery of more than 30 skeletons found underground at a depth of 322 metres(!), inside a coal mine in Bernissart, Belgium. Yup, these are the 'Bernissart Dinosaurs'. Absolutely beautiful! On display at the Royal Belgian institute of Natural Sciences. | Dr Dean Lomax - Palaeontologist
