酷東西

趣味知識

Gigantspinosaurus means 'giant spine lizard,' named for the huge comma-shaped spines on its shoulder blades.1

Its fossils include the first skin impressions ever found for any stegosaur, showing what its skin looked like.1

It lived about 168 to 161 million years ago, during the Middle to Late Jurassic.2

Gigantspinosaurus was a medium-sized stegosaur, bigger than the early Huayangosaurus but smaller than later stegosaurs like Tuojiangosaurus.1

The only known skeleton is almost complete, including a pair of lower jaws, neck and back bones, and a fused hip bone.6

Scientists think it was an adult because its teeth were worn down from chewing tough plants.1
