This is an unusual trilobite that we have not seen before a few months ago. It is an undescribed Calymenid from the Ordovician of Morocco. This type looks similar to the Diacalymene found there, but this type is larger and usually better articulated. The rock is also not the same - this matrix is very hard and dense. The trilobite is outstretched and has very unique natural coloration. This is a very displayable example of this unusual Calymenid from Morocco.
