Name: Isotelus gigasGeologic Age: Middle OrdovicianStratigraphic Detail: Trenton GroupLocation: Trenton Falls, New YorkDescription: This is a beautiful glossy, jet-black example of the trilobite Isotelus gigas, partially enrolled, from a classic U.S. locality. This is a very inflated trilobite that has been prepared to look as though it has wrapped itself around the small spire of freestanding matrix. Using a flexible measuring tape, this Isotelus measures 4.3cm (1.75 inches) from head to tail. The eyes are not compressed, a rare feature on this species. The trilobite has three compression areas where bryozoans once laid, causing large indentations in the shell. Otherwise a beautiful trilobite!
