Parasaurolophini
Parasaurolophini is a tribe of derived lambeosaurine hadrosaurids that are native to Asia, N. America, and probably Europe. It is defined as everything closer to Parasaurolophus walkeri than to Lambeosaurus lambei. It currently contains Charonosaurus (from the Amur River.), Parasaurolophus (from Utah, New Mexico, Montana and Alberta), and possibly Blasisaurus and Arenysaurus (both from Spain)
