This is an unusual trilobite that we have not seen before last month. It is an undescribed Calymenid from the Ordovician of Morocco. This type looks similar to the Diacalymene found there, but this type is HUGE - well over three inches long! The rock is also not the same - this matrix is very hard and dense. The trilobite is outstretched and has very unique natural coloration. It is not fully extracted from the matrix - there is a project for someone! This is a very nice example of this unusual Calymenid from Morocco.
