酷東西

趣味知識

Gryposaurus had a narrow, arching hump on its nose that looked like a Roman nose, which might have been used to tell species apart or to fight others of the same kind.1

Some Gryposaurus fossils even include skin impressions that show it had pyramid-shaped scales running along the middle of its back.1

Its teeth were packed into batteries of hundreds, and only a few were in use at a time, constantly being replaced like a conveyor belt.1

Gryposaurus probably lived near rivers, and it disappeared from the Dinosaur Park Formation before another duckbill called Prosaurolophus showed up.1

The species G. monumentensis was named one of the top 10 new species of 2008 by the International Institute for Species Exploration.1

Gryposaurus could reach food from the ground up to about 4 metres (13 feet) high, using its beak and cheek-like organs to hold plants.1
