Here is a beautiful trilobite pair from Nevada featuring a relatively rare Olenellus chifensis associated with an Olenellus gilberti. The Olenellus chifensis measures approximately 19 mm in length, while the Olenellus gilberti is about 12 mm wide. This is a quite rare combination having two trilobite species from the Pioche Formation preserved together on a single specimen.
