Kettneraspis Issoumourensis Alberti Trilobite 120mm

£397.00 GBP

Kettneraspis Trilobite is a fossilised Devonian period [417 to 354 million years ago] Arthropod, a sea bottom dweller. This genus type is known for its tall eye stalks, long genal spines and frilly cephalon, the head shield. It is an odontopleurid trilobite and found in the marine fossil strata globally. Odontopleurids first make their appearance in the Late Cambrian period approximately 540 mya, the last genera vanished from the fossil record by the end of the Frasnian stage 372 mya. The members of Odontopleurids or Odontopleuridae are noted for there exotic spiny appendages and ornamentations of their carapaces, giving them an alien appearance to us today.


Using the magnifying glass, one can see the exceptional elegant details of this arthropod. Each segment has been cleaned with air abrasive technology to expose the arthropods cephalon, the head, thoracic body segments and finally pygidium [tail]. The three-part lobed body giving the Trilobite its name, run laterally, the axis lobe (slightly raised) and the right and left pleural lobes which are quite distinct. Posteriorly of the cephalon is the distinguishing single occipital spine, nicknamed the 'stovepipe' due to its stout appearance.


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).


Overall this Kettneraspis trilobite is fortuitously placed. The fossilisation process has taken approximately four hundred million years, and the specimen has fossilised and mineralised well, the condition of this specimen as with many Devonian trilobites from this part of the world is excellent.


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.
