Preserved dung suggests large herbivores have lived in Yellowstone National Park for more than 2,000 years

Large herbivores like bison or elk have continuously lived in the Yellowstone National Park region for about 2,300 years, according to a new analysis of chemicals preserved in lake sediments. John Wendt of Oklahoma State University, U.S., and colleagues present these findings in the open-access journal PLOS ONE on October 30, 2024.
