酷東西

趣味知識

Daliansaurus had a big claw on the fourth toe of each foot, in addition to the sickle claw on the second toe that other troodontids have.1

Its foot bones were long, which suggests it was a good runner.1

Daliansaurus lived about 126 million years ago, during the Early Cretaceous period.1

It was a troodontid, a group of bird-like dinosaurs that were probably covered in feathers.1

The only known fossil of Daliansaurus is a nearly complete skeleton, with the head and neck curled backwards.1

Daliansaurus lived alongside other small troodontids like Sinovenator, Sinusonasus, and Mei.1

?What did Daliansaurus eat?

It was a small predator that ate small prey. It had sharp teeth with small serrations on the back ones, good for eating meat.1

?How fast could Daliansaurus run?
