Ordovician In Anti-Atlas Mtns. Area, Morocco

Recommended Posts

I would very much like to learn of the collecting experiences and about the fossils that other collectors may have obtained from the Lower and Upper Ordovician sites in southeast Morocco.

I haven't been there myself but I have an orthoceras fossil from the Atlas Mountains of around the same age.

I'd like to know more about those fossils/sites as well! I have a few of the more easily obtained things from each Fezouata and Ktaoua (if you do a Forum search for Eldonia you'll find my examples from the latter)..

I too have not been to Morocco but I have a large collection of Cambrian thru Devonian trilobite material. I will go thru my iphoto where I keep my trilobite catalog with annotated/metadata images and post what I have for the Ordovician Ktaoua and Fezouata (Upper and Middle to Lower Ordovician)

I used to have some echinoderm material but have traded it, now just have my trilobites as focus, so this is my Atlas Ordovician contribution to your question and thread. Enjoy. time for bed....... zzzzzzzzz

Very impressive, Russ!! Doesn't that Symphysops stevaninae have any eyes? Never seen anything like that before.

They have eyes just like the two Cyclopyge I posted, big eyes with many lenses. This one has a remnant of the eyes on it but like a number they are missing. Suppose it might have been a molt?

Here are a couple which are not mine. (one just a head, other is one Malek used to have for sale) showing the eyes, they look just like my first specimen of Cylopyge I posted.

It's rough going, no running water, heat, sudden haboobs, hard limestone etc. Some people camp out at the sites, others trek out from the closest towns for day trips. However the digging is fruitful if you put in your time, time being more key in the Ordovician sites in Morocco.

Aside from trilobites, you find a wide fauna including corals, brachiopods, bryozoa. Some of the localities are more of a mudstone clay, others are incredibly dense limestone.
