"In the past, springs and a wetter climate fed a lush, valley-wide wetland ecosystem that sustained large populations of mammoths, camels, bison, and giant ground sloths.
These herbivores were prey to animals like dire wolves and saber-toothed cats, said Steve Rowland, a paleontologist at the Las Vegas Natural History Museum. 'During the Wisconsin Glaciation, the Las Vegas Valley was a very different environment than it is today. It was a lot greener, and the climate was a lot wetter.'” —Mary Caperton Morton (@theblondecoyote), Science Writer
