Comments

Masterfully prepared by Malcolm Thornley @Malcolmt. This trilobite is one of the more uncommon species found at Penn Dixie and highly sought after within the Devonian strata of western New York. Recovered from a field dig, Bellacartwrightia sp. appears similar to G. boothi but there are subtle differences. Bellacartwrightia sp. has small bumps running down the axial lobe and a small spike towards the back of the cephalon. This particular specimen is wrapped around the rock. When it was first discovered only the pygidium was visible.

 

Special note:

This species is similar to that of B. whitelyi but currently B. whitelyi has never been confirmed as found from the Penn Dixie Windom Shale. Further classification is being undertaken to either confirm this species is B. whitelyi or a new species of Bellacartwrightia. See the Bellacartwrightia entry in Trilobites of New York; Whitelyi, Kloc, Brett 2002.
