Eolambia is the oldest known member of the family of duck-billed dinosaurs that we call lambeosaurs, and many believe it is also the earliest duck-billed dinosaur, which are also called hadrosaurs. Named in 1997 by Dr. James Kirkland, a Jurassic Park Institute scientist, it is a fairly recent discovery. Finding these type of early dinosaurs provide scientists with many clues about the evolution of dinosaurs. Since the duck-bills were the most abundant plant eaters of the late Cretaceous, learning more about their ancestry and how they evolved is an important part of understanding the prehistoric world.
