This is a rare opportunity to
obtain an unprepared Arctinurus from the Rochester Shale.
Preparation had just started at the front of the cephalon and then
stopped. The left side is obviously present. The right side dips
down into the matrix. The 3rd photo is of the back, showing the
edge of the thorax reaching the back. The shale is soft and easy to work,
however the trilobite is also very soft, so low air pressure and soft
dolomite3 are a must to prepare this speicmen. Or have it as
is, a valuable addition to your collection.
