Koshisaurus lived about 121 to 113 million years ago during the Early Cretaceous.2

It was a basal hadrosauroid, meaning it was an early relative of the duck-billed dinosaurs.1

Koshisaurus had an antorbital fossa, a hole in front of its eye socket on the skull, which is a primitive feature.1

Its teeth had at least three subsidiary ridges on the outer side, helping it grind plants.1

Koshisaurus shared its home with other dinosaurs like Fukuisaurus, Fukuiraptor, and Fukuititan.1
