Oak Springs Trilobite Site

The Oak Springs Trilobite Site consists of a small area where fossil-bearing shale outcrops on fairly level terrain along Highway 93 west of Caliente, Nevada. Trilobites here occur in the Combined Metals Member of the Pioche Formation, in tan and green shales dating from about 500-524 mya. Few specimens are intact, but it is easy to find legs and head shields from six species in the family Olenellidae. Link to more information.

Access to the site is via a paved highway and a short, graded dirt road leading to a parking area. From there, a 1/4-mile foot trail leads west to the quarry site, but for people who can't walk, drive west past the parking area about 0.2 miles to the first right turn.

A BLM sign-in register is located at the parking area and pamphlets are available to learn more about the history of the area and these creatures. There is also an interpretive sign and two picnic tables.
