During the Devonian period , Palaeozoic era , approximately 380 millions years ago, the Moroccan Sahara was a floor of a vast prehistoric  ocean , the first Mediterranean sea proto -tethys. Because of different natural factors , fish , plants and other old sea animals  were fossilized after the withdrawal of the sea . Lack of oxygen , tectonic  movements and high temperature are the main natural  factors . The south east Moroccan Sahara is now a rich source  of a very old and different fossils.



Geologically speaking , there are many land mines and quarries where fossils are embedded within huge rocks, each quarry has its specific features in term of age , raw material, and colour of fossils.


Trilobites , ammonites , goniatites and orthoceras are the main wide spreading  fossils in our Sahara . On the one hand , some fossils are embedded  within huge and vast marble quarries either from the black or the brown colour . For example the black one is very rich of orthoceras , the squids sediment, and the brown one is very rich of both ammonites and orthoceras .On the other hand, some other fossils are located in mountains that are very rich of limestone rocks such as trilobites .
More importantly , the Sahara is very famous with its unique fossilized marble . There are  two kinds of marble : the black one is very rich on the way to Merzouga , and the brown one which is 8 km far from Erfoud . The vast quarry is fully rich of the ammonites and orthoceras.
