Scientists Say "Seitaad Ruessi" was a 10-15 ft. Vegetarian, May Be Linked to Ancient Navajo Sand Monster MythThis undated handout photo provided by the Utah Museum of Natural History at the University of Utah, shows part of the skeleton of new dinosaur species, Seitaad ruessi. (AP/University of Utah)(AP) A new species of dinosaur has emerged from the rocks of southern Utah.
Buried by a collapsing sand dune, perhaps 185 million years ago, the new dino was probably a plant eater and an early relative of the giant animals later known as sauropods, researchers report in Tuesday's edition of the journal PLoS One.
Named Seitaad ruessi, the species was 10-to-15 feet long and 3-to-4 feet high. Its bones were found protruding from sandstone at the base of a cliff, directly below an ancient Anasazi cliff dwelling.
No humans were around at the time of the dinosaurs, but researchers say the bones could well have been visible when the early Indians lived there.
The name Seitaad comes from the word "Seit'aad," which was a sand monster that buried its victims in dunes in Navajo legend, according to the researchers. The newly named skeleton had been swallowed by a sand dune.
