The long-necked dinosaur Brachiosaurus has always stood out next to its sauropod kin. Its long front legs give it a prouder stature than other sauropods such as

So far scientists have only found a few neck vertebrae and half of a pelvis of Qiaowanlong, but that is enough to know that it was a very interesting dinosaur, indeed. It was "small" for a brachiosaur - an estimated 10 feet tall and 40 feet long - but what makes it really strange is a peculiar feature of its neck vertebrae. The neural spines, or projections on the top of the neck vertebra, are bifurcated, or have two crests with a trough between them. This feature was seen in many other sauropods but not in brachiosaurs, at least not until now. This would mean that this feature, which has important implications for how sauropods held their necks, evolved several times in multiple lineages of long-necked dinosaurs.
