Potamornis is known from just one partial skull bone, called a quadrate, which was found in Wyoming.3
It lived about 72 to 66 million years ago, right before the big extinction that killed the non-bird dinosaurs.1
Potamornis belonged to a group of ancient birds called Hesperornithiformes, which were mostly diving birds with teeth.3
The name Potamornis means 'river bird', because it was found in rocks that were once a riverbed.3
Scientists think Potamornis was a ground-dwelling bird that could run fast on land.3
It laid eggs, like all birds do, and probably built nests on the ground.1

?What did Potamornis eat?
It was a meat-eater (carnivore). It likely hunted for fish and other small animals in the water.3
