Hi
Help … can anyone identify this trilobite. As a geology teacher, I was given this specimen long ago by a student/ parent. Unfortunately I do not know where it was sourced , & therefore have little clue to it’s possible name, let alone the stage or series of strata it came from. It is set in a dark grey shale (bit like Hope Shale ??) with some very very fine quartz grains in the matrix. It looks a bit like a Cambrian Ogygopsis, but this species is not found locally in Shropshire/ mid Wales. Can you suggest an ID.
