Abstract
a dubious species of hadrosaurs in the subfamily Saurolophinae. It is so similar to Edmontosaurus that some researchers consider them the same species. A duck-billed dinosaur that lived above the Arctic Circle near the end of the Cretaceous, Ugrunaaluk, bore crests along its spine and is estimated at 25 to 30 feet long and 7 feet high at the hip. Several thousand bones belonging to the species have been found on the Colville River in northern Alaska in strata from 69 Ma. Late Cretaceous.
