Lesser-Known Wonders: 30 Fascinating Dinosaurs You’ve Probably Never Heard Of

Yamatosaurus

This duck-billed dinosaur represents one of Japan’s first major hadrosaur discoveries. Named in 2021 though found in 2004, Yamatosaurus roamed what is now Awaji Island during the Late Cretaceous. The plant-eater helps scientists understand how hadrosaurs spread across eastern Asia. Before this find, Japan remained largely unexplored territory for dinosaur discoveries compared to mainland Asia.
