Problematica
Early Ordovician (Arenigian)
Upper Fezouata Formation
Zagora, Morocco.

Unidentified spheres reminiscent of Pollingeria from the Burgess Shale.  The spheres average 15mm each on 75mm slab.

This is for the hardcore collector of Early Paleozoic weirdness.

I think Problematica put out one album in the 80’s but broke up after that due to creative differences.
