About Sonorasaurus:

There wasn't much special about the appearance of Sonorasaurus, which adhered to the basic body plan of Brachiosaurus-like sauropods: an extremely long neck and a thick trunk supported by significantly longer front than back legs. What makes Sonorosaurus interesting is that its remains date from middle Cretaceous North America (about 100 million years ago), a relatively sparse stretch of time when it comes to sauropod fossils. By the way, the euphonious name of this dinosaur derives from Arizona's Sonora Desert.
