DescriptionThis complete specimen represents Laggania cambria. A ventral view, the head of this ancient creature is visible on the left. Lateral lobes are clearly present along the sides of the body, particularly in the anterior section. One eye is preserved in a yellowish colour and can be seen between the head and foremost lobes (near the top of the specimen). Laggania cambria is related to Anomalocaris. Although they are fairly similar in appearance, Laggania can be distinguished by the location of the eyes, its claw type and smaller body. Laggania and Anomalocaris both belong to the dinocarida class, an extinct group of primitive arthropods living in the open ocean waters that existed during the early and Middle Cambrian (520-505 Ma).
