Here is a large Trilobite specimen of the species Olenellus gilberti from the Pioche shale of Nevada. Sadly the slap is a little to small for the Trilobite. Or the Trilobite is a little to large for its matrix. | |||
Location: | Ruin Wash, Lincoln Co., Nevada, USA | ||
Size: | about 55 mm long | ||
Age: | Lower Cambrian, Pioche Formation (about 520 Ma) |
