Utah's red rocks – world-famous attractions at numerous national parks, monuments and state parks – have yielded(生產,產出) a rare skeleton of a new species of plant-eating dinosaur1 that lived 185 million years ago and may have been buried alive by a collapsing2 sand dune3(沙丘) . The discovery confirms the widespread success of sauropodomorph(蜥腳類) dinosaurs4 during the Early Jurassic Period(侏羅紀) . Until now, Utah's red rocks were known only for a few scattered5 bones and dinosaur footprints. However, discovery of a remarkably6 preserved partial skeleton is being published in the March 24 edition of PLoS ONE, the online open-access journal produced by the Public Library of Science.

The study was conducted by Joseph Sertich, a former University of Utah master's student and current Stony7 Brook8 University Ph.D. student, and Mark Loewen, a paleontologist(古生物學者) at the Utah Museum of Natural History and instructor9 in the Department of Geology(地質學) and Geophysics(地球物理學) at the University of Utah.

The new dinosaur species is named Seitaad ruessi (SAY-eet-AWD ROO-ess-EYE), which is derived10 from the Navajo word, "Seit'aad," a sand-desert monster from the Navajo (Diné) creation legend that swallowed its victims in sand dunes11 (the skeleton of Seitaad had been "swallowed" in a fossilized sand dune when it was discovered); and Ruess, after the artist, poet, naturalist12 and explorer Everett Ruess who mysteriously disappeared in the red rock country of southern Utah in 1934 at age 20.

Seitaad ruessi is part of a group of dinosaurs known as sauropodomorphs(蜥腳亞目) . Sauropodomorphs were distributed across the globe during the Early Jurassic, when all of the continents were still together in the supercontinent named Pangaea. Millions of years later, sauropodomorphs evolved into gigantic sauropods, long-necked plant eaters whose fossils are well known from elsewhere in Utah, including Dinosaur National Monument.
