Waukeshaaspis
''Waukeshaaspis'' is an extinct genus of trilobite (a diverse group of marine arthropods) known from the lower Silurian aged Waukesha Biota. A single species is currently known, ''Waukeshaaspis eatonae'', which is known from strata belonging to the Telychian aged Brandon Bridge Formation in Wisconsin. Originally discovered alongside the Waukesha Biota in 1985, this genus wouldn't be properly described until 2024. Currently, this genus is placed within the family Dalmanitidae, within the larger Phacopida, which lasted from the Lower Ordovician to the Upper Devonian. This genus is rather unique, as it is the only common trilobite found within the Waukesha Biota, and is usually preserved in a more complete state compared to other contemporary genera. Its abundance is also notable, with around 200 or so specimens having been recorded, making it one of the most abundant organisms at the site. This arthropod is so common, that entire planes of rock have been found with dozens of preserv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waukesha Biota
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. It is known for the exceptional preservation of soft-bodied organisms, including many species found nowhere else in rocks of similar age. The site's discovery was announced in 1985, leading to a plethora of discoveries. 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. Some of the species are not easily classified into known animal groups, showing that much research remains to be done on this site. Other taxa that are normally common in Silurian deposits are rare here, but trilobites are quite common. History an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
