Waukesha Biota, Paleontological site in Waukesha County, Wisconsin, United States.
The Brandon Bridge Formation contains preserved marine fossils from the early Silurian period within two quarries in southeastern Wisconsin.
Scientists first documented this fossil location in 1985, establishing it as one of the few known sites with soft-body preservation from Silurian times.
Research institutions and museums utilize the fossil specimens from this location to educate students and further scientific understanding of ancient marine life.
The primary collection area spans a 12-centimeter layer of fine-grained marine sediments, requiring specialized tools and careful excavation techniques.
The site contains an exceptional concentration of trilobite fossils while lacking typical Silurian period specimens like corals, gastropods, and brachiopods.
