The Wheeler Shale (named by Charles Walcott) is a Cambrian (c. 507 Ma) fossil locality world-famous [1] for prolific agnostid and Elrathia kingii trilobite remains (even though many areas are barren of fossils) [2] and represents a Konzentrat-Lagerstätte.
Asaphiscus wheeleri, 37 mm long. Asaphiscus are average size trilobites of (up to 8 centimetres or 3.1 inches) with a rather flat calcified dorsal exoskeleton of inverted egg-shaped outline, about 1 + 1 ⁄ 2 × longer than wide, with the widest point near the back of the headshield (or cephalon).
