酷東西

趣味知識

Obelignathus is known from only a single jaw bone, a right dentary, found in 1990.2

Its jaw is about three times longer than it is high, which is shorter and thicker than in its relatives.1

Obelignathus lived between about 83 and 66 million years ago, during the Late Cretaceous period.3

This dinosaur was originally thought to be a species of Rhabdodon, but scientists later gave it its own genus in 2025.2 1

Obelignathus belonged to a group called rhabdodontomorphs, which were plant-eating dinosaurs that lived on islands in Europe.1

The name Obelignathus combines 'Obelix' (a strong cartoon character) and the Greek word for 'jaw'.1

發現: The jaw bone was found in 1990 near Montouliers, France. It was first named Rhabdodon septimanicus by Éric Buffetaut and Jean Le Loeuff in 1991. In 2025, Czepiński and Madzia renamed it Obelignathus.2 1
