Excellent Olenellus fowleri Nevada Cambrian Trilobite

Description: Lower Cambrian Pioche Shale trilobites of this level of preservation have become exceptionally difficult to obtain in the last few years. Olenellus fowleri are perhaps the most aesthetically pleasing of the trilobite fauna list found in the Uppermost Lower Cambrian of Nevada. Above the extinction zone from which these species were collected the Ollenids are no longer in existence. What a shame, they were amongst the most beautiful of trilobites, true butterflies of the sea.

This fully adult sized trilobite is in good/very good condition. Note the long flowing thoratic spines descending well below the terminal axial piece. The opistothorax and tail spine are missing, as are the tips of some of the pleural spines.
