Lapampasaurus lived during the Late Cretaceous in South America and is one of the few Hadrosaur-species that lived on the continent. It has been assumed that South America was an island during the Late Cretaceous, but the presence of Lapampasaurus and a few other Hadrosaurs is proof that there must have been a landbridge or very narrow waterway were they could cross. Lapampasaurus was a fairly small Hadrosaur and grew to approximately six meters in length.
Lapampasaurus cholinoi is the only species in its genus and has been described from just a few bone fragments found in Argentina in 1991.
