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.
