Rare Russian trilobite Niobe schmidti

Name: Niobe schmidti

Trilobite Order Asaphida, Superfamily Asaphoidea, Family Asaphidae

Geologic Time: Lower Ordovician

Size: 2.6 inches

Fossil Site: Asery Horizon, St. Petersburg region, Wolchow river, Russia

Here is a Asaphid trilobite that few collectors have haerd of, much less seen. Coming from the Lower Ordovician Wolchovian Level deposits of the Wolchow River region near Saint Petersburg, Russia, this is an example of the trilobite known until a few decades ago as Niobe frontalis (now Niobe schmidti). It is betrayed as such by the fine terrace lines on the axial lobe, the only one from the region to be so adorned. The trilobite itself is 2.6 inches long (measured along the curve) and 1.3 inches wide at the widest extent of the cephalon.
