Kaijiangosaurus

名字的意思： “Kaijiang lizard, named after the Kai River in China”1

吃：肉肉食恐龍侏羅紀中期

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!1 4

酷東西

趣味知識

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
