Enrolled Psudodechenella rowi Trilobite from New York

Description: The Proetida have the distinction of being the longest-lived order of trilobites They arose during the Early Ordovician and persisted until the end-Permian Great Dying. This one was first known as a member of the genus Basidechenella until some 40 years ago when the North American members were assigned their own genus, Psuedodechenella. Partial examples are far more common than one such as this enrolled specimen seen here with a small brachiopod. See my other offerings for a fine prone Pseudodechenella rowi.
