ScienceDaily (Mar. 24, 2010) — Utah's red rocks -- world-famous attractions at numerous national parks, monuments and state parks -- have yielded a rare skeleton of a new species of plant-eating dinosaur that lived 185 million years ago and may have been buried alive by a collapsing sand dune. The discovery confirms the widespread success of sauropodomorph dinosaurs during the Early Jurassic Period.
