The Waukesha Biota (also known as Waukesha Lagerstätte, Brandon Bridge Lagerstätte, or Brandon Bridge fauna) is an important fossil site located in Waukesha County and Franklin, Milwaukee County within the state of Wisconsin. This biota is preserved in certain strata within the Brandon Bridge Formation, which dates to the early Silurian period.[1] It is known for the exceptional preservation of soft-bodied organisms, including many species found nowhere else in rocks of similar age.[2] The site's discovery was announced in 1985, leading to a plethora of discoveries.[1][2][3] This biota is one of the few well studied Lagerstätten (exceptional fossil sites) from the Silurian, making it important in our understanding of the period's biodiversity.[1][2] Some of the species are not easily classified into known animal groups, showing that much research remains to be done on this site.[1][3] Other taxa that are normally common in Silurian deposits are rare here, but trilobites are quite common.[3]
