I've received some new brachiopod specimens from Morocco recently and this Gypidulid is one of them. The shell is about as wide as it is long with very unequal valves. The pedicle valve is very convex and curved while the brachial valve is only slightly convex. There is no sulcus in the shell and it is smooth except for some very fine concentric growth lines. I believe this should be called Devonogypa spinulosa after reading the paper, Middle Devonian brachiopods from the southern Maïder [...]
I've only recently become proficient enough to recognize Spinocyrtia brachiopods apart from Mediospirifers when collecting the middle Devonian in New York. When I saw the fossils below for the first time, though, I knew they looked familiar. They are Spinocyrtia elburzensis from Jebel Oufatene near Alnif in Morocco and they come from middle Devonian aged rocks (Emsian stage). They have a very striking resemblance to S. granulosa which is found in the Givetian stage rocks of New York.I posted [...]
I've been wanting to get some Devonian fossils from Morocco that were not trilobites for some time now. My thought was that they had to exist out there in the desert but that they weree just being overlooked by the collectors since they could make more money selling trilobites. Lucky for me that I stumbled upon a dealer on Facebook who did have some brachiopods from Jebel Issomour for sale and I snapped them up.This is Glyptogypa multiplicata and comes from rocks dated to the Eifelian [...]
