酷東西

趣味知識

Sinusonasus had a wavy nose bone, which is why its name means 'wave nose'.1

Its tail had long bones called chevrons that connected to form a flat plate under the tail.1

Sinusonasus had a sickle claw on its second toe, like a Velociraptor, which it could use to grab prey.1

Its lower leg was long, so it was probably a fast runner.1

The front teeth of Sinusonasus had no serrations, but the back teeth had serrations only on the back edge.1

Sinusonasus lived about 125 to 119 million years ago, during the Early Cretaceous.2
