Lobopods
Lobopods are a bizarre group of extinct animals that have a segmented, worm-like body with legs. They may be related to living forms such as the onychophorans (velvet worms), tardigrades (water bears), and the arthropods. A number of globally distributed Cambrian species have been assigned to this group.
One example of a Cambrian lobopod from Utah is Acinocricus stichus Conway Morris & Robison, 1988. The spinose fossils of Acinocricus stichus were first interpreted as algae, but are now thought to be lobopodian (Ramskold & Chen, 1998).
Another example of a Middle Cambrian lobopod from Utah is Aysheaia prolata Robison, 1985.
