The Waukesha Biota, a 437-million-year-old fossil assemblage from Wisconsin, USA, provides a rare glimpse into life in an ancient lagoon. In his book Wonderful Life Stephen Jay Gould (1989) compared the range of form of Cambrian animals in the Burgess Shale with only five other fossil sites in the world; one of them was at Waukesha.
Spectacular new fossils from the Waukesha Biota have been revealed for the first time.
