DescriptionA ventral view, this specimen represents the front portion of Anomalocaris canadensis. The anterior claws are spread at 180 degrees, while some of the body segments bearing lateral lobes displayed in a downward fashion are visible near the bottom of the image. The disc-like structure just below the division of the claws represents the jaw. The posterior end of this specimen is missing. After decay, different elements of the body disarticulate - particularly the harder more resilient parts such as the jaws and claws. Consequently, finding a nearly complete specimen like this one is extremely rare. Anomalocaris belongs to the dinocarida class, an extinct group of primitive arthropods living in the open ocean waters that existed in the early and Middle Cambrian (520-505 Ma). Anomalocaris is the largest of the dinocarids known to date, and it was probably a fast swimmer and an active predator or scavenger.
