Haopterus was a flying reptile that lived about 124 million years ago. It had a long, pointed snout full of sharp teeth, and it probably soared over the sea to catch fish.1

Haopterus was the first pterosaur fossil from China to preserve a complete skull.1 2

Its skull was about 14.5 centimeters (5.7 inches) long, and it had 12 pairs of teeth in both the upper and lower jaws.1

The first three pairs of teeth in the front of its mouth were very small, and scientists think they might have been newly erupted replacement teeth.1

Haopterus had a fan-shaped breastbone with a strong keel, which helped anchor the muscles for flying.1

Its hind legs were weak, and its foot bones were very short, so scientists think it walked on all fours when on the ground.1

The fossil was found in 1998 at the Sihetun locality, and the rock layer was dated to 124.6 million years old.1

?How big was Haopterus?

Its wingspan was about 1.35 metres (4.43 feet). Its skull was 14.5 centimetres (5.7 inches) long.1

?What did Haopterus eat?

It probably ate fish. Scientists think it was a piscivore, meaning it caught fish while soaring over the sea.1

?Did Haopterus have a crest on its head?

No, it did not. Its skull was low and lacked a crest.1

Atosɛm sɛefoɔ

Atosɛm: Haopterus was a dinosaur because it lived with dinosaurs.

Nokorɛ: Haopterus was a pterosaur, a flying reptile that is not a dinosaur.1
