Archaeologists discover ancient bison bones in Vero Beach
In what is considered one of the oldest and most important archaeological digs in North America, scientists have uncovered what they believe are the bones of a 13,000- to 14,000-year-old ancient, extinct species of bison at the Old Vero Man Site in Vero Beach, Fla. Archaeologists from Florida Atlantic University's Harbor Branch Oceanographic Institute made this discovery just 10 feet below the ground's surface during the final stretch of the 2016 excavation efforts at the Vero Beach site.
"This finding is especially significant because of the meticulous documentation that has been involved," said James M. Adovasio, Ph.D., principal investigator. "Along with the fact that bones like this have never been found on land as part of a calculated archaeological effort. Others like this have all been found underwater, in sinkholes or streams."
Bison antiquus, sometimes referred to as the "ancient bison," was the most common large herbivore of the North American continent for more than 10,000 years, and is a direct ancestor of the living American bison. They were approximately 8 feet tall, 15 feet long and weighed close to 3,500 pounds.
"We couldn't have asked for a better representative species from that era," said Andrew Hemmings, Ph.D., lead archaeologist. "We now know that people were here in Vero Beach at that time."
The bones of the ancient bison have been moved to FAU's Ancient DNA Lab at Harbor Branch for further research and examination. The lab was established in 2011 to investigate the population biology, genetic diversity and species composition of past ecosystems.
Scientists also found other bones at the site from small mammals, along with slivers of bones from large mammals that could have come from mammoth, mastodon, sloth or bison. Pieces of charcoal and the head of a fly were discovered earlier in this year's excavation, which began in late February.
The Old Man Vero Site was originally discovered in 1915 after construction efforts on a drainage canal exposed the well-preserved remains of late Pleistocene flora and fauna in association with human remains and artifacts.
