Polk County, Florida paleontological sites, Paleontological excavation sites in Polk County, Florida.
Polk County paleontological sites are a collection of excavation areas where fossils from multiple geological periods have been uncovered. These deposits span from the Early Miocene through the Late Pleistocene and contain bone remains of vertebrate creatures that once inhabited South Florida.
The region underwent a major shift as marine environments transformed into dry land between about 17.7 and 1.5 million years ago. This change preserved the remains of many animals that died and were buried during these geological periods.
Local museums and educational institutions organize field expeditions to these locations, enabling researchers and students to examine prehistoric Florida specimens.
The fossil sites are spread across multiple locations throughout the region, with many revealed through phosphate mining activities. Visitors should research in advance which excavation areas are accessible to the public, as not all sites may be regularly available for viewing.
These sites have revealed not only land animals such as bears and horses, but also marine mammals like ancient whales. This uncommon mix demonstrates how the environment shifted from water to land and left different habitats compressed in a single area.
