I visited the American Museum of Natural History (AMNH) in New York city in July 2018. In the Grand Gallery was a trilobite display case with world-class specimens. This trilobite fossil was in the Ordovician section and named Paraceraurus exsul . It was found in the Asery Formation of St. Petersburg, Russia. Accession number is Fl-74833 and was donated by the family of James Kaste.

Their trilobite exhibit was made possible by Dr. Martin Shugar, M.D. and Andy Secher who are also editors for the AMNH trilobite web site.
