In Depth The full type species name for this dinosaur is Lepidus praecisio which means ‘fascinating fragment’. This is because while not many fossils of this dinosaur are known, we can observe that the astragalus (talos) and calcaneum are fused into one, which is a trait of neotheropod dinosaurs. At the same time however, the … Read more

In Depth Xingxiulong is a genus of sauropodomorph dinosaur that lived in China during the early Jurassic. The robust nature of the fossils bones strongly suggest that Xingxiulong would have been heavily built in life, though likely still would have been bipedal.
