When oil companies search for oil under the seabed, they have to drill really far down. In their hunt for oil, they might find bone fragments.
One such piece of bone became Norway's first dinosaur find - and a world record.

“They drilled through a dinosaur that we have managed to identify,” says paleontologist Jørn Hurum.
He and a German researcher examined the bone more closely using a microscope. They soon realised that it must belong to a dinosaur of the type plateosaurus.
