Has anyone come upon accounts of Native Americans finding dinosaurs and other prehistoric reptiles? I was reading a book about early dino discoveries in North America and I've heard of the Native American sand beast Seitaad (for which the prosauropod Seitaad is named). It's also interesting that the dubious tyrannosaur Dryptosaurus kenabekides is named after Kenabeek, a T. rex-like beast of Native American folklore. Would it reasonable to assume that the Native Americans occasionally came upon bones of dinosaurs and other prehistoric reptiles when they devised myths and legends of Native American monsters like Kenabeek and Seitaad?
