Trilobite localities worldwide

Photographic journey through the Palaeozoic era

Unfortunately there are but few images available on the internet of the actual locations trilobites are found in, despite the fact that it must be very interesting for both enthusiasts and collectors alike to know the origin of their beloved trilobite specimens and to be able to see these locations, although one may not be able to go there. We therefore would like to show you some images taken by persons who went there on excursions. All images copyright by Trilobita.de or their legal owners respectively.


1. Marokko - Jbel Gara el Zguilma, near Foum Zguid

Famous for the first finds of trilobites of the genus Walliserops and the trilobite made famous by Richard Fortey, Erbenochile, with it's skyscraper-resembling towering eyes. The latter ones are being found in the lower and lowest geode layers mined so far.

Geographical Situation: Some 50 km south-east of the small city Foum Zguid in Southern Morroco.

Age: Devonian, Emsian, Timrhanrhart Formation

Stratigraphy: The main target of excavations are 2 irregular horizontally-oriented geode layers which are situated some 1.50 m apart from each other. The upper layer is directly exposed at the surface by an ever-shifting flooding plain, it is however often very weathered and broken in itself. The material in itself has a dirty yellow color and the exoskeletons of the trilobites found are dark brown. Between the beforementioned geode layers there is a soft marl layer that only rarely yields geodes. For the time being, it is not known what can be found beneath these layers, as there have not been any excavations deeper then 2 meters so far.

Trilobite fauna: In both layers the exact same variation of trilobites can be found. The only difference is in quantity. For example in the upper geode layer Walliserops with long tridents are more common then the ones with short tridents and in the lower geode layer it is the other way around. As of today finds of the following trilobites have been made at this location: Phacops (3 different species), Acastoides, Gerastos, Cornuproetus, Diademaproetus, Scutellum, Hollardops, Kayserops, Cyphaspis (with long and short genal spines), Homalonotus, Erbenochile, Psychopyge (3 different species), Walliserops (3 different species), Leonaspis and Sculptoproetus. In addition to that goniatites and brachiopods can also be found.

Additional Information: If you are interested to see this and other fascinating places for yourself, feel free to contact Ait Hssaine Hammi of Erfoud (email: zguilma@yahoo.fr). He is a renowned guide not only to the Devonian trilobite quarries in Southern Morocco. Emails in English or French, please! (Unless you can write in Berber! <g>)


2. Marokko - Alnif region and Jbel Issoumour

The next images are displayed here courtesy of Yinan (www.trilobia.com). The information about the exact location is limited, however I am still able to offer the reader some interesting sights. The images show the locality Timzarzit near Alnif and the famous Jbel Issoumour from which the giant phacopids as well as other special trilobites such as Psychopyge are known. The images date back to the year of 2005.

Geographical Situation : 20 km east of Alnif, locality Timarzit (Alnif 1-2) / north-eastern end of the Ma'der lowland, elevations reach up to 500 meters high stretching over several kilometers.

Age: Devonian

Additional Information: Thanks once more to Yinan for kindly allowing us to use his photographs on our website. He made these photographs during his journey to Morocco in spring 2005 when he visited several different localities in the Anti-Atlas.


Other photographs can be viewed on the subpage Specials. On this page we plan to show more Locatilities as well as other aspects of trilobites in the future.

Detailed descriptions of our journeys to the Palaeozoic of Southern Morocco, including many images, can be found in both our old and new forum. The place in which to look for are the sections "Fundstellen und -orte / Quarries" respectively. The aforeplaced links will lead you there (in German).
