Protista: Division Chlorophyta (Green Algae):
The algae at the Pipe Creek Sinkhole are represented by fossil oogonia of Chara sp. (Stonewort). These macroalgae are indicative of mineral rich waters. The limestone that surrounds the sinkhole certainly would have provided an extremely mineral-rich environment, especially in terms of Ca and Mg.
Plantae: Division Bryophyta: Class Musci (mosses):
Mosses are represented by a single taxon, Bryum sp. intdet. This taxon occurs commonly in the deposit as leaf thalli and other fragments. Species of Bryum occupy a wide variety of habitats.
Aquatic Vascular Plants:
One taxon, Potamogeton sp., represented by achenes, is indicative of submergent aquatic conditions. Fossils of this taxon are uncommon in the Pipe Creek deposit. All of the other vascular plant remains recovered are wetland or upland species.
