Olenellus is one of the earliest known trilobites.  It lived only during the Early Cambrian and is known from various localities across North America.  It had a rather flat body.

Areas to legally collect fossils in California have become more restricted over the past thirty years and this is especially true for hunting trilobites there.  Here’s your chance to pick up what might be considered the classic California trilobite.
