Trilobite with AntennaDescription: With the discovery of the Chengjiang Biota in 1984 a window on the Cambrain 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 Eoredlichia Trilobiteagnathan 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 trilobite is a species of Eoredlichia, a member of the Family Redlichiida. Trilobites from this timeframe were members of the Redlichiida, Ptychopariida, Corynexochida, and the Agnostida, with the balance of the orders appearing later in time. What is most unusual about this one is that the whip-like antennae have been preserved.
