Description: Canadaspis perfecta is a bivalved arthropod found in the Burgess Shale Fauna of British Columbia. It is the only taxon from the region known from both single and multiple examples that presumably succumbed together. It was presumably a benthic organism that Candaspis made a living walking on the seafloor, using its limbs to sir up the bottom sediment It is the type species of a genus also found in deposits in Utah and Nevada. An older species C. laevigata is known from the Chengjiang Biota of China (see my other listings). Note the abdomen and legs seen outside the carapace. This wonderful example shows incredible detail for a specimen more than a HALF BILLION years of age. Coming from the famous Burgess Shale Fauna, this is a highly-desirable member which will make a fine addition to any collection of Cambrian Explosion fossils. Since the location is now a World Heritage site only specimens from old collections such as this are available.
