Eldredgeops rana
Vendor: Fossil Soup
SKU Number: SQ8576413
Beautifully inflated and prone Middle Devonian Eldredgeops rana from Western N.Y. This example is especially unusual in that it has darker markings over almost all of the exoskeleton. The spots are probably related to camouflage. The pleural lobes have areas that are far lighter than the rest of this trilobite - very unusual compared to the majority of trilobites from this site. A beautiful inflated prone, amazing coloring and on a nice sized piece of shale.
Full dimensions are listed below.

Additional Information
Phacops / Eldredgeops
Eldredgeops is a recently introduced genus (1990), replacing Phacops as the name for the common North American Devonian Phacopid trilobite. The change was necessary to distinguish between morphological differences observed in Phacopid trilobites on the African and European edge of the Rheic Ocean and those on the N. American edge.
Calymmene latifrons, the first Phacopid trilobite to be described, was found in Gerolstein, Germany. Unfortunately the holotype was lost and topotype material was used until a neotype specimen was designated in 2006. The neotype was designated Phacops latifrons and is now the definitive specimen for the description of Phacops. When a change in name was suggested, it was the N. American trilobite that received the new genus name as the European trilobite had been described first.
