izinto ezimnandi

Iinyani ezimnandi

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

Scientists have not found enough bones to know its full size, but it was likely smaller than later duck-billed dinosaurs. Only a partial skeleton is known.1 3

?What did Koshisaurus eat?

It ate plants, using its beak to snip leaves and its ridged teeth to grind them up.4 3

?When did Koshisaurus live?

It lived during the Early Cretaceous, about 125 to 115 million years ago.3 5

?Where was Koshisaurus found?

Its fossils were found in Fukui Prefecture, Japan, in the Kitadani Formation.4 3
