UF Pine lsland pollen study leads to revision of state's ancient geography

>"Depending upon the anticipated uses of future injection wells, the developers might find it very interesting to know that what they will drill into is not likely to be simple and homogeneous," Rich said. "There is a buried landscape down there and the engineers need to know that is the case."Klug said the age of the sample was determined by analyzing the foraminiferas' carbonate shells and comparing the layer to sediments recovered from the same depth. "I think it's really very interesting," Klug said. "It's a preliminary study but what it shows I think is that the information is available for anybody who's willing to spend the time looking into it."

Pine Island was the site of a Calusa Indian village for more than 1,500 years and is important for research in archaeology and ecology. The Florida Museum maintains the Randell Research Center at Pineland, an archaeological site on the northwest part of the island.

"Our studies of environmental change at Pineland show that while sea level is rising very quickly today, water levels fluctuated up and down when the Calusa inhabited the area from AD 1 to 1700," said William Marquardt, Randell Center director and curator of archaeology at the Florida Museum. "Jarzen and Klug's new findings from the Eocene epoch may be suggesting something similar 35 million years ago that there were fluctuations during the Eocene that periodically exposed land in Florida."
