Herbstosaurus was a flying reptile, not a dinosaur. It lived in the Late Jurassic period in what is now Argentina. This pterosaur was small and probably ate fish.1 3

Datu dibertigarria: pterosauroak dinosauroen gainetik hegan egiten zuten, baina haien lehengusuak ziren, ez dinosauroak.

Datu dibertigarriak

Herbstosaurus was first thought to be a small dinosaur, like Compsognathus. Later scientists realized it was a pterosaur, a flying reptile.1 2

The only known fossil of Herbstosaurus is a partial skeleton, including parts of the pelvis, sacrum, and both thigh bones. It is preserved in a sandstone nodule that also contains an ammonite shell.1 2

The name Herbstosaurus honors Rafael Herbst, the paleobotanist who found the fossil in 1969.1

Herbstosaurus lived about 149 to 143 million years ago, during the Tithonian age of the Late Jurassic.3 2

Scientists think Herbstosaurus might belong to a group called Dsungaripteroidea, but this is not certain. It is a deeply nested pterodactyloid pterosaur.2

The fossil of Herbstosaurus was found in the Vaca Muerta Formation in Argentina, a place known for many Jurassic marine fossils.3 2

?Was Herbstosaurus a dinosaur?

No, Herbstosaurus was a pterosaur, a flying reptile, not a dinosaur. It was first thought to be a small dinosaur, but later scientists realized it was a pterosaur.1 2

?How big was Herbstosaurus?

Herbstosaurus was small, but its exact size is not known because only a partial skeleton has been found. It was originally thought to be one of the smallest dinosaurs, but it is a pterosaur.1 2

?What did Herbstosaurus eat?

Herbstosaurus probably ate fish, like many other pterosaurs. Its fossils were found in a marine rock formation, suggesting it lived near the sea.1 2

Mito-hauslea

Mitoa: Herbstosaurus was a dinosaur.

Egia: Herbstosaurus was actually a pterosaur, a flying reptile, not a dinosaur. It was originally mistaken for a small theropod dinosaur.1 2
