Well Articulated But What Is It?

[hitekmastr]

My wife found this very well articulated fossil that looks like a bivalve internal - found in the Tully formation (Devonian) in central New York. Would appreciate help with an I.D. This piece is very striking and is going on display in my office.

This is how it looks in my office, on the shelf - as you can see, it's a large piece and very artistic:

I found a couple species of Grammysioidea that look very similar. Fig. 12 is G. subarcuata and Fig. 13 is G. arcuata. There are other Grammysioidea that also look close and this monograph should get you pointed in the right direction. Congrats on a textbook example!

Thanks for the ID and especially for the book reference - this is really helpful since this is our "Devonian year." Last year was mostly a "Carboniferous year." I'll post a trip report soon - it was remarkable what we were able to find in just a day and a half, everything from trilobites to crinoid pinnules, and some interesting bryozoa and shells - as well as more Devonian trees that was our primary goal. We were on the lookout for really unusual specimens and were really focused, which paid off as you can see. This bivalve is on a one foot long piece of shale and makes a wonderful display piece, also. The detail is really incredible - as you say, "textbook quality."
