Wiwaxia is a genus of soft-bodied, scale-covered animals known from Burgess shale type Lagerstätte dating from the upper Lower Cambrian to Middle Cambrian. The organisms are mainly known from dispersed sclerites; articulated specimens, where found, range from 3.4 millimetres (0.13 in) to a little over 5 centimetres (2.0 in) in length. The precise taxonomic affinities of the genus are a matter of ongoing debate amongst palaeontologists.
