ARCHEOLOGICAL FINDINGS IN GRAY'S REEF NATIONAL MARINE SANCTUARY Gray's Reef National Marine Sanctuary may have been a site of ancient human settlement during the last geologic time period and thus may hold the key to ancient culture and history along the coast. Dr. Erv Garrison, University of Georgia marine archeologist, is attempting to document the reefs' existence above sea level some 15,000 years ago when Georgia's shoreline extended more than 60 miles eastward. Off the coast, divers have turned up fossils of now-extinct land-dwelling animals, such as ground sloths, mastodons and early camels, horses and bison. "Where you find the animals, you most likely are going to find humans, " says Garrison. Fossils and plant life discovered in our underwater sanctuaries may give us vital clues and insight into future climate changes and sea level rise. The following is a list of fossil bones found by researchers at the Gray's reef National Marine Sanctuary during studies beginning in April,1995 to August, 1998. This project is led by Dr. Erv Garrison, Univeristy of Georgia marine archeologist   See article on Dr. Garrison's research on the Year of the Ocean Daily News.   1995: 1 bone fragment; mammal 1 non-bone, marine worm burrow cast; Radiocarbon date of 18,000 + years 1996: 4 bone fragments, mammal; 2 are rib-like and quite large - over 150 mm in length; one is less mineralized and identified as an extiinct species of bovine animal. This bone was radiocarbon dated to 8000 years. 1 tooth, Pleistocene horse; heavily mineralized 1997: 1 bone fragment, mammal; small less than 100mm in length; found on NPR- National Geographic Radio Expedition 2 bone fragments, mammal; one may tooth fragment 1 antler or bone fragment, heavily mineralized; possibly worked by humans as a tool 2 non-bone,marine worm burrow casts 1998: 2 unidentified fossil fragments; one does not appear to be bone - horn or antler? 1 bone fragment, mammal; appears to be limb bone fragment - over 135 mm in length 1 non-bone, burrow cast fragment
