Olenellus
chiefensis
Trilobite
Order Redlichiida, Family Olenellidae (described by Palmer, 1998)
Geological
Time: Lower Cambrian
Size: 35
mm
Fossil Site:
C- Shale, Combined Metals Member, Pioche Shale Formation, Lincoln County,
Nevada
Description:
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.
