Availability:In stock

Details:

A good specimen displaying the key attributes of the genus type, particularly the inflated granulous glabella (head shield), segmented thorax and narrowing pygidium (tail section) also exhibiting large preserved schizochroal eyes, which display many convex lenses, these lenses set in an alveoli framework of the sclera. When rolling fingers over these many attributes one can attempt to connect to the palaeozoic era.

Details

The Barrandeops cf. granulops trilobite was discovered in the fossil layers of Bou Teharafine, the ridge of Hamar Laghdad. Prehistoric fossil layers can be found containing fossil coral reefs. One can discover tabulate and rugose corals, along side several trilobite specie; In the fossil bed layers of the Lower Devonian (Emsian stage) around 408,000,000 to 393,000,000 years old which are a hot-bed of excavations in the search of ancient trilobites.


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 enrol, possibly for a defence posture. The name trilobite refers to the three-part body shape, this is longitudinally referenced to the tri-lobed effect of the whole arthropod and not, as often is the case, mistaken for the three main and distinctive constituent parts of the carapace, the cephalon (head), the thorax (body) and the pygidium (tail).
