Bristolia? sp Resser 1928
Bristolia sp Lower Cambrian Latham Shale, Marble Mtns, 3.4km NW of Chambless Store at junction of National Trails Hwy and the Cadiz Rd. Lat 34.5873N 115.5226W (Estimated from Sat Photo) In trilobite rich bed about 10m above base of formation and 30cm below a clay layer. This is an ollenelid trilobite with advanced genal spines. Probably makes it Bristolia rather than Olenellus. The beds here have yielded well preserved cephalons of Bristolia/Olenellus mohaviensis as well as poorly preserved specimens of a bristolid with further advanced spines -- tentatively Bristolia bristolensis

The images have not been edited at the pixel level. However contrast, brightness, saturation, sharpness, gamma and/or color balance may have been adjusted to maximize detail and resolution has been tinkered with to minimize storage requirements. I still have a LOT to learn about digital photography and expect to go through several generations of images of these fossils over the next decade or two.
