This is one of the scarcest and most sought-after trilobites from New York State. It is a huge Monodechenella macrocephala from the limestone zone of the Centerfield Strata. For a short time in the 1980's, this site produced Phacops, mostly from the shale, but is known worldwide for the rare Basidechenella and Monodechenella found there. The site yielded about 100 Phacops for every Basidechenella, and about 40 Basidechenella for every Monodechenella. There have only been a handful of complete Monodechenella found in the limestone, and this is one of them.

This trlobite is complete with both free cheeks intact and tightly articulated. The trilobite is over two inches long, and would be almost three inches if the bug was fully prone! The thick shell exoskeleton is beautifully preserved, with the reticulation of the many pustules easily seen - because the fossil was only recently prepared with air abrasive tools! In the '80's, almost all Monodechenellas were prepared with crude tools. See what modern techniques can do - the entire cephalon has been prepared in a free standing manner! This is one type of trilobite that will not be flooding the market anytime soon. This may be the only Monodechenella from the limestone that you will see that is not in a collection...yet.
