Beautiful CALYMENE niagarensis Rochester Shale Trilobite


1 in stock


A classic trilobite from the famous Rochester Shale Silurian Deposits of New York. Unfortunately these trilobites are becoming more rare as this quarry is beginning to play out.

Here is a great example of the trilobites coming from this classic and well known site. The CALYMENE trilobites from this location exhibit outstanding detail. They normally are preserved with a rich black color on a dark gray or gray matrix. Many from this site are also preserved with outstanding inflated carapaces that make these trilobites very showy. This is a trilobite on the large side of average.

The trilobite itself is 1 3/8 inch by 3/4 inch on an irregular gray matrix 5 1/4 by 4. This one is a GREAT example of this bug. It does have a small pit on the glabella which sometimes occurs during fossilization. A void is created and doesn’t fill with minerals.
