Upper Cambrian mortality plate

[terapoza]

Hello.I found in my collection another very problematic piece. It was found in Tømte, Ringsaker district in Norway. This upper Cambrian black bituminous shale formation contains some anthraconite concretions and layers. This anthraconite or black bituminous limestone also called stinkstone because of characteristic smell when hammered is full of cephalons and pygidiums. Finally after few hours of research I choose two zones of Olenids. First is Olenus & Agnostus obesus zone, subzone Wahl ( Olenus wahlenbergi). Second choice is Agnostus pisiformis zone with Olenus alpha. In my opinion specimen below coming from Olenus wahlenbergi and Agnostus obesus zone. 

Any hints and other ideas will be very helpful.
