Aysheaia pedunculata
Aysheaia pedunculata An extinct invertebrate, known from fossils found in the Middle
Cambrian Burgess Shale that, although marine, is considered a likely ancestor for the extant members of the phylum
Onychophora that exist in humid tropical forests. It possessed an elongate, worm-like body with a terminal mouth and frontal pupillae. The body was segmented and bore 10–43 pairs of walking legs.
