1

Potamornis is known from just one partial skull bone, called a quadrate, which was found in Wyoming.3

2

It lived about 72 to 66 million years ago, right before the big extinction that killed the non-bird dinosaurs.1

3

Potamornis belonged to a group of ancient birds called Hesperornithiformes, which were mostly diving birds with teeth.3

4

The name Potamornis means 'river bird', because it was found in rocks that were once a riverbed.3

5

Scientists think Potamornis was a ground-dwelling bird that could run fast on land.3

6

It laid eggs, like all birds do, and probably built nests on the ground.1
