A sauropod dinosaur tooth has been recovered from the Kilmaluag Formation (Middle Jurassic: late Bathonian) of Strathaird, Isle of Skye, Western Scotland. It represents the first dinosaur tooth to be described from Scotland. The combination of character states present indicates that it cannot be referred to either Cetiosaurus or Cardiodon and that it may pertain to a basal eusauropod or a basal titanosauriform. A diversity of sauropods was present in the UK in the Middle Jurassic and these faunas have the potential to illuminate many aspects of sauropod evolutionary history.
