Secernosaurus

separated lizard

• secernere · Latin · to separate
• sauros · Greek · lizard

The name combines the Latin "secernere" (to separate) with the Greek "sauros" (lizard). Brett-Surman chose it because this South American hadrosaurid was separated, geographically, from the hadrosaurs of the northern continents. Its discovery showed that duck-billed dinosaurs had reached the southern landmass.
