Need help with ammonite ID

[Sagebrush Steve]

 

I was in Moab, Utah last week and stopped in at the Moab Rock Shop.  They had lots of fossils so I picked up this nice little ammonite about 17 mm diameter for a few dollars.  It was labeled as an Orthosphinctes from the Jurassic of the Atlas Mountains of Morocco, but I'm not convinced.  I can't find much online about Orthosphinctes but what I do find shows the whorl cross section as being much more oval in shape.  I found the thread below from 2014 but it doesn't seem to have answered the poster's original question of Orthosphinctes vs. Perisphinctes.  Can anyone help?

Hi, Steve!

I don't know the difference between the two, but I cannot recall seeing anything listed as being Orthosphinctes from Morocco. 

And this specimen doesn't seem to be any Moroccan preservation or shape that I can recall. 

This looks Madagascan to me.

That may be why I can’t find anything about Orthosphinctes in Morocco on google.  I’m sure the rock shop bought their stuff at the Tucson fossil show, so the IDs might not be accurate.

I can't help with the identity but it looks Madagascan to me too. I wonder how many fossils are floating around out there with location stated as 'Morocco' when 'Madagascar' was intended, or vice versa.

@Sagebrush Steve Check out Dichotomosphinctes from the Madagascarian Oxfordian. That's a Perisphinctes subgenus....Actually Properisphinctes bernensis would be an even better guess.
