Dinosaur fossils are exceptionally rare in the Arabian Peninsula. Scientists have now uncovered the first record of dinosaurs from Saudi Arabia. What is now dry desert was once a beach littered with the bones and teeth of ancient marine reptiles and dinosaurs. A string of vertebrae from the tail of a huge “Brontosaurus-like” sauropod, together with some shed teeth from a carnivorous theropod represent the first formally identified dinosaur fossils from Saudi Arabia.
