BergeroniellusThis is the lower Cambrian Ellipsocephalid trilobite Bergeroniellus asiaticus, once assigned to Redlichiidae of the Order Redlichiida. Coming from Cambrian Botomian Stage deposits, it is truly ancient, dating to some 520 to 525 million year ago. It thus lived in a perilous time for trilobites, as the end-Botomian mass extinction was quite severe, wiping out a large swatch of marine life forms.
