These arthropods are all from the Cambrian intertidal sandstone of Central Wisconsin. As you can see in the stereoscopic image above, there is alot of relief between high and low areas. Preservation is 3-D, including such anatomical features as limbs. The image just to the right of the stereo pair is a camera lucida drawing of the same slab. Legs are clearly visible in the middle arthropod.
