Chengjiang Mollisonia FossilDescription: This unusual arthropod is known as Mollisonia sinica. The genus was described from the younger Burgess Shale. With the discovery of the Chengjiang Biota in 1984 a window on the Cambrian Explosion in China was opened. The diversity of soft-tissue fossils is astonishing: algae, medusiforms, sponges, priapulids, annelid like worms, echinoderms, arthropods (including trilobites), hemichordates, chordates, and the first agnathan fish make up just a small fraction of the total. Numerous problematic forms are known as well, some of which may have represented failed attempts at diversity that did not persist to the present day. The taxon has been found in the younger Kaili Biota of China. The species has just recently been discovered in the Chengjiang Biota itself, making this possibly the third member of the genus, and the oldest of all.
