Phacops rana rana (Green)
These are by far the most common trilobites at the site, pieces of them
can be found all over the place, however finding complete, prone (unenrolled) ones is another story.

Most trilobites found here are enrolled. These are typical
examples of enrolled Phacops.

This guy is nearly perfect except for the tip of its nose. It is
also very 3-D, standing a good 1/4" out of the rock.

This is a flawless enrolled Phacops that I took 95%
out of the matrix, with a pyratized shell 1/2" away
Most trylobytes are found here enrolled usually with the Cephalon (head) missing.

These are in the Tichenor Limestone, and were very difficult to extract. For all the work I did, I
wish at least one was complete, however they are both missing their trilo-butts, or pygidium.
