Coltraneia oufatenensis trilobite dating from the Palaeozoic era, early Devonian era, Upper Lochkovian age, approximately 419 millions years. Originating from El Otfal formation, Jbel Oufatène, Morocco in North Africa.
The eyes of this individual are excellent and easily studied even without the aid of a powerful lens, the nodules of the lenses defined and conspicuous. The compound eye of Coltraneia oufatenensis trilobite makes the type easily recognisable, Coltraneia closely related to the trilobite Treveropyge from which it differs as Coltraneia having larger eyes and more photoreceptor compound lenses, ommatidia. All phacopina trilobites had schizochroal eyes, these were a multi arrangement of hundreds of compound lenses made from calcite. In this specimen Coltraneia oufatenensis trilobite the eyes can be clearly defined with their multi lens feature.
Another identifier of the Coltraneia are the lobes behind the glabella, the first three lobes, lobe one is slightly lower as the thorax of the Coltraneia oufatenensis is slightly raised, causing lobe two and three to be slighly higher. This leads to the thoracic segments and the terminal spines which in this specimen are all well defined down to the pygidium, tail.
The superb specimen Coltraneia oufatenensis trilobite professionally prepared to reveal it from the rock layer of the fossil bed, the fossil silts have been left in place and sculptured below the trilobite to form a pedestal of natural contemporaneous Devonian period limestone which may have been this individuals demise, it is believe that often landslips caused many trilobites and other marine life to be suddenly covered and encapsulating the victims for over four hundred million years. An anoxic, lack of oxygen environment is beneficial for the process of fossilisation to be successful, aiding petrification and retarding bacterial growth.
This rare type Coltraneia oufatenensis trilobite is a very good example from this great Moroccan fossil site. The Order of Phacopida, Suborder Phacopina, Superfamily Acastoidea, Family Acastidae, Subfamily Asteropyginae, Genus Coltraneia oufatenensis, Lieberman & Kloc c1997.
The preparitor of this Coltraneia oufatenensis trilobite is one of our dedicated Moroccan team, the trilobite was personally hand collected by our fossil digger and technician from the fossil bed, carefully with the aid of the latest techniques cleaned for display. We guarantee authenticity and quality with all our specimens this the little Coltraneia oufatenensis arthropod trilobite is no exception to this guarantee. It requires many diligent hours and patient concentration with a pneumatic pens driven with mechanical compressors to clean limestone rock from the specimens carapace or exoskeleton without damaging the fossil arthropod. The rarity coupled with the technical skill required to extract and prepare this specimen elevates this Coltraneia oufatenensis trilobite to the upper levels of study and collecting.
