Trilobite Olenellus chiefensisDescription: A beautifully preserved part/counterpart trilobite specimen of this species that has been recently described in 1998. The genus is restricted to the early Cambrian (540-520 million years ago), making them good index fossils. They have a most distinctive large cephalon containing crescentic eyes, making them quite attractive to collectors. Most are only found as a preserved cephalon, making those from the famous Pioche Shale highly desirable.
