Istiodactylus was a flying reptile with a wide, blunt snout full of sharp, interlocking teeth. It lived about 120 million years ago and probably used its teeth like a cookie cutter to slice meat from big dead animals.1 2

Its skull was about 45 centimetres (18 inches) long and had a semicircle of 48 closely spaced, triangular teeth that interlocked to form a razor-edged outline.1

The lower jaw had a tooth-like projection that fit into the upper teeth, helping it bite cleanly.1

Some of its back vertebrae were fused into a structure called a notarium, which helped support its large wings.1

Its hindlimbs were very short, while its forelimbs and wing-finger were huge, making it a soaring specialist.1

For much of the 20th century, it was the only pterosaur known from three-dimensionally preserved fossils, giving scientists a rare look at pterosaur anatomy.1 2

Its teeth were unlike the long, curved fish-grabbing teeth of other pterosaurs, so scientists think it did not catch fish but instead scavenged.2

It lived in river and coastal environments in southern England, where the climate was warm, about 20 to 25 °C (68 to 77 °F).1

?How big was Istiodactylus?

Its wingspan was about 4.3 to 5 metres. Its skull was about 45 centimetres long.1 2

?What did Istiodactylus eat?

It was a scavenger. It used its sharp, interlocking teeth like a cookie cutter to slice meat from dead animals.1 2

?Was Istiodactylus a dinosaur?

No, it was a pterosaur, a flying reptile that lived at the same time as dinosaurs but is not a dinosaur.1

?Could Istiodactylus fly?

Yes, it was a flying reptile with large wings. It may have been a soaring specialist, gliding long distances to find food.1

Mosenyi wa ditshomo

Tshomo: Some people think Istiodactylus was a dinosaur because it lived with dinosaurs and had sharp teeth.

Nnete: Istiodactylus was a pterosaur, a flying reptile, not a dinosaur. Pterosaurs are a separate group of reptiles.1
