Redlichia takooensis  TrilobiteThis specimen of Redlichia takooensis is from the famous Emu Bay Shale of Australia. The Emu Bay Shale is Australia’s only Burgess Shale type deposit. It has fauna in common with both the younger Burgess Shale and the slightly older Chengjiang Biota. Unlike the Burgess Shale and Chengjiang Biota, however, the Emu Bay Shale deposits were a shallow water depositional environment. This is the largest trilobite of the Emu Bay Biota, reaching a maximum of 250 mm in length. Some have been known to demonstrate soft tissue preservation of legs or antennae. It genus is also found in the Cambrian of south China.
