趣味知識

Concavenator had a hump on its back made from two tall bones in its spine.1

Scientists found small bumps on its arm bone that might be quill knobs, places where feathers attach.1 2

It lived about 130 to 125 million years ago during the Early Cretaceous Period.1

Its fossils were found at Las Hoyas in Spain, which was once an inland lake.1

Concavenator belongs to the carcharodontosaur group, which means 'shark-toothed lizards'.1

The hump on Concavenator's back might have been used for display or to store fat, but scientists are not sure.2
