History of this Trilobite Specimen:
This species of trilobite as you can see has been known by Paleontologists and collectors alike for many years. There has never been a complete specimen ever found. However many segments of this trilobite have been found at the quarry and based on those fossils a reconstruction as you see here has been done by Mr. George Rennie of Ct. under the guidance and research by Dr. Copeland McClintock of Yale University Division of Invertebrate Paleontology. At This time this model is on display at the Peabody Museum at Yale. To date this trilobite is considered to be the Largest known to have lived on the North American Continent....

Terataspis grandis (Hall. 1861) ----Holotype NYSM 4543

Type species. Terataspis grandis is found in both the lower Onondaga
Limestone of western New York, particularly the former Fogelsanger Quarry in Williamsville, Erie County, and the upper Schoharie Formation of eastern New York. The large size and spiny nature of this trilobite make it one of the more spectacular ones.  Only one specimen is known from
New York  it is complete enough for a reasonable reconstruction. This specimen is upside down, and half, longitudinally, is missing. It is in the Buffalo Museum of Natural History, Buffalo, New York.  The drawing  shows where the genal spine appears on the exoskeleton. "Only one reasonably complete specimen is known from New York." Certainly a good number of pieces are known.
