Found in association with a skeleton of the sauropod dinosaur Spinophorosaurus, the tooth likely dates to the Bathonian stage of the Middle Jurassic, 14 million years prior to Ostafrikasaurus. If this identification is correct, MUPE HB-87 represents the oldest known evidence of spinosaurids in the fossil record.
The fossil belongs to a young Azhdarchid pterosaur, also known as Cryodrakon boreas, with an estimated wingspan of 6.5 feet, according to the University of Reading.
