Details:

An good specimen displaying the key attributes of the genus type, particularly the genal spines, segmented thorax and wide pygidium (tail section) also exhibiting preserved schizochroal eyes, which display many convex lenses, these lenses set in an alveoli framework of sclera. when rolling a finger over these eyes one can attempt to connect to the palaeozoic era.

Zlichovaspis rugosa trilobite (formerly Odontochile) re-named trilobite. The arthropod has been worked out of a bedrock block, this matrix is the original fossil bedrock, the age of which is around 400 million years ago. The trilobite expired in the silts of that time which have hardened into solid limestone. Here the articulation is very interesting, showing the constituent parts of the carapace (exoskeleton), of the once living invertebrate.


This trilobite was discovered in the fossil layers of Atchana, the fossil bed layers of the Lower Devonian (Pragian stage), around 411,000,000 to 408,000,000 years old are a hotbed of excavations in the search of ancient trilobites. In area's the quarrying activity results in mile-long extended gullies, and in previous years focussed mainly on two 'couches' or strata, the Dicranurus-couche and the Kolihapeltis-couche.


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).
