👉 Ateuchosaurus is a genus of sauropod dinosaur that lived during the Late Cretaceous period, approximately 69 million years ago. It was described by fossil records from Italy and Spain in the late 18th century and later studied more thoroughly through modern molecular and radiocarbon dating techniques. The genus has been associated with several species, including Ateuchosaurus dux, which is known for its large jawbone and distinctive tooth structure.
