Ctenochasma was a flying reptile with a mouth full of hundreds of long, thin teeth that stuck out like a comb. It used its special beak to scoop up tiny animals from the water, like a spoonbill bird today.1

1

Ctenochasma had over 400 teeth in adults, all long, thin, and tightly packed together.1

2

Its teeth stuck outward from the jaws, forming a basket-like shape that helped catch small prey.1

3

Adult Ctenochasma had a bony crest on top of their skull, but young ones did not.1

4

Scientists think Ctenochasma was nocturnal, like some seabirds today, based on its eye bones.1

5

The smallest species, Ctenochasma elegans, had a wingspan of about 1.9 metres (6.2 feet) as an adult.1

6

Ctenochasma lived during the Late Jurassic period, around 150 to 145 million years ago.1

German paleontologist Hermann von Meyer named Ctenochasma in 1851, based on a lower jaw full of teeth. He first thought it was a crocodilian, not a pterosaur.1

Scientists debate whether all the different species of Ctenochasma are really just growth stages of one species, but a 2007 study showed three distinct species based on tooth number and shape.1
