in 1889. Historically, several species were assigned to it, all based on extremely fragmentary remains, but there is no evidence to support these assignments, making the type species, ''P. grallipes'', the only valid species. Most of these other species' remains likely belong to better-known hadrosaurs, such as ''

Lambeosaurus ''Lambeosaurus'' ( , meaning " Lambe's lizard") is a genus of hadrosaurid dinosaur that lived about 75 million years ago, in the Late Cretaceous period (Campanian stage) of North America. This bipedal/quadrupedal, herbivorous dinosaur is kn ...
