Mercyhurst Dig Suggests Human Presence at Controversial Old Vero Man Site

ERIE, Pa., Dec. 16, 2014 (GLOBE NEWSWIRE) -- Were he alive today, E.H. Sellards, Florida state geologist in the early 1900s, would likely have reveled in the validation of his controversial theory that humans co-existed with large prehistoric animals some 14,000 years ago in Vero Beach, Florida. And he would have had the Mercyhurst Archaeological Institute (MAI) to thank.

In what MAI Director James Adovasio, Ph.D., describes as the most extensive Paleoindian excavation currently under way in all of North America, that being the Old Vero Man site where Sellards drew his now century-old conclusions, evidence uncovered recently by MAI positively demonstrates the contemporaneous presence of humans and late Pleistocene animals.

The MAI began its Vero excavation last year at the invitation of the Old Vero Ice Age Sites Committee (OVIASC), a dedicated group of citizens determined to define Vero's rightful place in the archaeological record. OVIASC has been instrumental in raising the funds necessary for the first season of excavation that ran January to May 2014, and will commence again in January 2015.

Although actual human remains were not retrieved in the dig's first round, certain artifacts identified during the excavation, among them burned fragments of bone, some with cut marks; could only be the work of human beings, Adovasio said.

"It's taken more than 100 years, but we now know that Sellards was right," he added, crediting rigorous excavation protocols and new technology that enabled investigators to proceed with a precise understanding of the site's geology – an advantage Sellards did not have.

Further, radiocarbon dating of the soil where much of the cultural materials have been found – in all, 170 species of plants and animals from MAI and earlier investigations – goes back 13,000-14,000 calendar years, making Vero the oldest terrestrial archaeological site in all of Florida and one of the oldest in the entire Southeast U.S.

Adovasio said MAI archaeologists and students also uncovered a buried soil layer dating back some 19,000 years, and that is where they intend to concentrate their second excavation in January.

"If that stratum or layer produces cultural materials, it will be one of the oldest locations in all of North or South America," Adovasio added.

While the current findings are significant to Floridians, Adovasio said the Vero site also plays a role in the more far-reaching debate surrounding the founding populations of the Americas. Historically, the first agreed-upon culture in the Americas was called Clovis, after a site discovered in New Mexico in the 1920s. Sites identified as Clovis dated around 11,200 – 11,500 radiocarbon years ago. But, beginning in the 1970s, sites predating Clovis began to be discovered, such as Pennsylvania's Meadowcroft Rockshelter, where Adovasio was principal excavator; Monte Verde in Chile and Gault in Central Texas.

Those discoveries – and now Vero – go a long way toward proving Clovis believers wrong and turning most archaeologists on Adovasio's side of the debate.

Moving forward, Adovasio said that subsequent investigations are expected to reveal the interrelationship of human, animal and plant populations at Vero. He said their hope is "to distinguish lifestyles of the folks who might have lived at Vero in terms of how much they match or don't match other behavioral models from other sites."

Adovasio and his colleagues (C. Andrew Hemmings, A.E. Marjenin, F.J. Vento and A. Vega) made their first presentation on the Vero excavation last month at the 71st Annual Southeastern Archaeological Conference in Greenville, South Carolina. Their symposium presentation was titled "The Old Vero Man Site: Current Investigations Suggest Pleistocene Human Occupation."

The faunal and floral materials recovered, among them a bone tentatively identified as that of a dire wolf, now extinct, are being studied in the archaeology labs at Mercyhurst University, creating a rare and historic opportunity for students.

MAI is now working with Florida Atlantic University scientists, who intend to analyze ancient DNA found at the dig site to provide yet another glimpse of the Florida landscape at the end of the last Ice Age.
