Inglis quarry

The Inglis quarry or Inglis quarry sites 1A and 1C are assemblages of vertebrate fossils dating from the Pleistocene ~1.8 Mya—300,000 years ago, located in the phosphate quarries near the town of Inglis, Citrus County, northern Florida.

Inglis sites FCi-1, FCi-2, Inglis Formation, Florida Geological Survey C-11, Inglis Member, Moodys Branch Formation, and Dunnellon Phosphate Company pit no. 5 are composed of a variety of bivalves, echinoderms, gastropods, crustaceans (mud shrimp), crinoids dating from the Eocene to Early Oligocene of ~48–33.9 Mya.^[1]^[2]

Inglis site 1A was originally a sinkhole spanning 10 by 20 meters. From bottom to top, the sequence comprises a basal conglomerate, a thin clay bed, a lower sand unit, a second thin clay bed, an upper sand unit, and a cemented quartz sandstone.^[3]
