The Cambrian Evidence That Darwin Failed to Comprehend


















                                                        A fossil Hallucigenia

                   A reconstruction of fossil Hallucigenia

                   bled a caterpillar with lobe-like appendages and isolated plates on

                   its dorsal surface. Newly identified features confirm that the spines
                   were used for defense. Underneath, it had seven pairs of legs, each
                   ending in a claw. 73


                        Odaraia
                        Odaraia’s structures make it one of the most remarkable
                   Burgess Shale life forms. It had two rather large eyes and two valves
                   meeting along the ventral margin. As an appendage to the ab-
                   domen, it had three blades.
                        The animal appears to have been an active swimmer and used
                   its large eyes to seek out smaller organisms for feeding. Odaraia in
                   all likelihood possessed the ability to swim upside down. This way
                   the uneven drag that would otherwise have occurred because of the
                   gap between the valves was minimized. Its appendages provided
                   the power for swimming. The limbs of its head section were small,
                   however there is some evidence of small antennae and a powerful
                   mandible. 74
