reviewjournal.com — News: After 50 years, Tule Springs still fascinates Page 3 of 3 Asked how scientists know there weren't humans in North America before 13,000 years ago, Orlins said, "We don't. We don't have the evidence yet.’ However, he said, some day a man-made tool or projectile point could turi up in extinct animal fossils from an earlier period. Meanwhile, work continues in the vicinity of Tule Springs by a California team from the San Bernardino County Museum led by curators Kathleen Springer and Eric Scott. Scott said the team discovered 438 fossil sites in the area and is analyzing them to find out what the animals ate and how their numbers changed ov« time. Of particular interest are mammoths, each of which ate 700 pounds vegetation per day. The research could shed light on how climate change played a role in the animals' demise. "When climate changed at the end of the Ice Age, there was less water," Scott said. "The plants took a hit, and then the anim als took a hit."
