Canadaspis perfecta

Canadaspis perfecta, is an extinct genus of bivalved arthropod that lived during the Middle Cambrian period. Fossils of this creature are primarily found in the Burgess Shale of British Columbia, Canada, and also in other locations like in the United States, and China. Characterized by its distinctive bivalved carapace, it's believed to have been a benthic animal, meaning it lived on the seafloor. Its appendages suggest that it likely moved by walking and may have used them to stir up sediment in search of food. The study of Canadaspis perfecta provides valuable insights into the diverse and complex marine ecosystems of the Cambrian era.
