All animals previously found at the site, near Bluff, Utah, were relatively small, probably because the desert habitat didn't support much vegetation. Those animals include relatives of modern crocodiles, mammalian ancestors called tritylodonts and two carnivorous dinosaurs, both of which probably preyed upon the sauropodomorph.
Seitaad was remarkably well preserved in the Navajo Sandstone, but its head and parts of its neck and tail were lost due to erosion over time. The researchers, however, believe Native Americans living 500 feet above in an ancestral Puebloan (Anasazi) cliff dwelling 1,000 years ago could see the now-missing dinosaur bones.
"Native Americans living in the region would certainly have recognized the bones of Seitaad as animal bones," Loewen explained. "Many people who eat meat off the bone, rather than processed and packaged in a grocery store, have a basic knowledge of the skeleton of animals."
"(The bones) were a beautiful white in the pink sandstone when we first saw them," he noted. Loewen added that the early Native American cliff dwellers even had "a slab with a dinosaur track incorporated into the window sill, perfectly centered."
