Here is another pyritized Goniatite from Morocco that I was able to identify using a webpage in Japan, hosted by Gifu University, that has a very comprehensive and illustrated page of Goniatites that appear to be from Morocco. It's called Kosmoclymenia sp. and has narrow, rounded whorls with a very simple suture pattern that kind of looks like Harry Potters forehead scar. I don't know what part of Morocco this comes from but I believe it's Devonian (Famennian stage) in age.
Right side (with some matrix still to be removed)
Keel with the last suture chamber (possibly the living chamber?).
