In summary, the fossils from the Kirkwood Formation are closely related to some of the most well-known gigantic sauropod dinosaurs, including the famous Diplodocus and Brachiosaurus. These dinosaurs roamed the area including Addo Elephant Park, Port Elizabeth, Uitenhage, and Nelson Mandela Bay 135 million years ago.
More specifically, we found evidence for a type of giant brachiosaur, one of the tallest animals to have ever lived; a smaller more generalized sauropod similar to Camarasaurus; a long, lean diplodocid, which likely had a whiplash tail; and a dicraeosaurid, which has long spines on its neck that might have supported twin sails.
What's quite cool is that these new fossils add a great deal to our knowledge of the Early Cretaceous. We have so little evidence for giant sauropods at that time in Earth's history - in fact, until recently we thought that diplodocids went extinct at the end of the Jurassic.
Keep your eyes on the Kirkwood Formation - Billy de Klerk and other collaborators have many cool new stories still to tell!
