Palaeolenus TrilobitesDescription: This trilobite assemblage is a group of members of the Order Ptychopariida from the Early Cambrian Heilinpu Formation deposits of the Caijiachong Valley, Yunnan Province, China, known as Palaeolenus . The diversity of soft-tissue fossils from the Cjengjiang Biota 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.

This is a well-preserved grouping of mostly counterpart examples of trilobites from the Chengjiang Biota that made up a glimpse of the Cambrian Explosion some 5-10 million years before the Burgess Shale fauna came into being.
