Paralejurus hamlagdadicus trilobite 51mm Phylum Arthropoda, Class Trilobita, Order Corynexochida, Sub order Illaenina, Family Styginidae, Genus Paralejurus Specie type Paralejurus Hamlagdadicus, has been carefully prepared with air abrasion and pneumatic tools to reveal the carapace from the matrix (bedrock), which has been etched to aid an attractive presentation and to present the specimen trilobite in a dramatic way, the dark carapace being picked out against the lighter matrix of sedimentary silt, now fossilised limestone. This North African, Paralejurus Hamlagdadicus trilobite is from the Devonian Period, around 395 to 345 million years.

A brief trilobite history. The order or group of trilobites evolved during the Pre-Cambrian period approximately 550 million years ago, One of the most complex forms of early life, the trilobites reign lasted over 270 million years coming to an end around 250 million years ago in the time of the Permian period. Trilobite genus-types were diverse and globally extensive. The Trilobite was a member of the Proetida Order, Family of the Proetidae. Trilobites were complex animals, having the first compound eyes and segmented bodies which enabled them to enrolled, possibly for a defence posture.

Few specimens are unearthed from many fossil sites in Morocco compared to the heyday of discoveries, beds become more difficult to manage as fossil material is excavated from deeper deposits. Other factors which influence the outcome of fossils collecting generally we now find less quality specimens in the fossil layers. Many fossil sites suffer erosion, some frequent flooding, dwindling specimens in the fossil bedding plane, and deeper layers of the fossilerous limestone contribute particularly to many types becoming less available.

Our Devonian trilobites are collected in the field by our associates in North Africa and prepared by technicians in the Moroccan fossil Lab. We therefore have a historical link to our fossil diggers and our specimens enabling us to authenticate and guarantee all our trilobites. We often travel to far flung fossil bed locations to collect directly from the fossil diggers, technicians or merchants. We work closely with our team to secure specimens which have merit and this trilobite is one of those occasions, secured in the Western Sahara.
