Kaijiangosaurus
Kaijiangosaurus was a meat-eating dinosaur that stomped around China during the Middle Jurassic, about 170 million years ago. It was a fierce hunter with sharp teeth and strong claws, but we only have a few bones of it, so it's still a bit of a mystery!14

Fun facts
Kaijiangosaurus had teeth like a megalosaur, with only a few serrations (tiny saw-like bumps) near the tip of each tooth.1
Its neck bones were short and wide, with low spines, and the front ones had a concave (curved inward) back edge.1
The hand claws of Kaijiangosaurus were strongly curved, perfect for grabbing prey.1
The shoulder blade (scapula) was fairly straight, with a slight narrowing at the lower end and a light expansion at the top.1
The upper arm bone (humerus) had a triangular deltopectoral crest, a spot where muscles attached.1
Some scientists think Kaijiangosaurus might be the same as another dinosaur called Gasosaurus, because they were found in the same rocks.1
