.57" Radnoria Trilobite From New York - Rare Species
This is a nice, .57" long specimen of a rare species of trilobite from the Rochester Shale of NY, Radnoria sp. They are only known from a single layer of the formation. This specimen is just under a half inch in length, which is about typical for the species. This one is a really nice example, being good sized, inflated and good shell preservation.
