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. Fossil specimen in talus below the Walcott Quarry, with large body sclerites clearly visible, and longer spines oriented to the north-east of the image.Wiwaxia was originally described by W.D. Matthew in 1899, from an isolated spine that had been found earlier in the Ogyopsis Shale, and classified as a hyolithid. Further specimens were found by American paleontologist Charles Doolittle Walcott in 1911 as a result ...
