Rare Leningradites longispinus Russian TrilobiteDescription: This is an example of the unusual trilobite Leningradites longispinus. It is a member of the Order Asaphida, Family Asaphidae, and a member of the Subfamily Pseudoasaphinae. Its affinities with the genus Pseudasaphus is obvious, but the long backswept genal spines are a distinguishing feature of the taxon. It has been prepared with the genal spines freestanding, making for a dramatic display of one of the truly rare Asaphids found in the Ordovician limestone deposits of the Wolchow River region of Russia. I have seen very few examples of the taxon, and none more dramatic than this one.
