Here we have the very first rib of the dead hadrosaur from Jurassic World Rebirth. Only two dinosaurs were made for the film. One was the hadrosaur and the other was Dolores, the young Aquilops. Most of the jungle scenes were filmed in Krabi, Thailand. The hadrosaur was completely destroyed after filming and thrown away. An American living in Krabi collected the parts and turned them into a tourist attraction. You can actually see in the original film that it is the rib. In the making-of footage, you can see even more clearly that it is indeed the rib. The hadrosaur is still being painted there.
