The story in short
In 2025, Ł. Czepiński and D. Madzia published the name Obelignathus. The name honors a person tied to the fossil or its study.
It lived in the Late Cretaceous (Campanian · Maastrichtian), roughly 83.6 to 66 million years ago. Finds come from France. It was a herbivore and walked on two legs.
The fossils of Obelignathus are too incomplete for a responsible length, hip height, or weight, so those fields are left blank on purpose.
On the family tree it sits in Rhabdodontomorpha, among the ornithopod dinosaurs.
