Age
Era: Neogene
Period: Pleistocene
Faunal stage: Rancholabrean 126,000—11,000 years ago, calculates to a period of approximately 0.115 million years.
Sites
- Rock Spring site (Pleistocene). Time period: ~126,000—11,000 thousand years ago. Specimens were collected by H. J. Gut, J. Mann, J. Todd, G. Lintner, circa 1939.[1] The site was recorded as bone-bearing argillaceous sandstone overlaying Ocala Limestone containing macrofossils. "The bones are well mineralized, and most are unworn; frequent occurrence in association of bones from what appear to be the same individual indicates that the material has not been reworked." (Glen E. Woolfenden 1959).[2][3][4]
Coordinates: 28.7°N 81.5°W
