Details:

Cyphaspis Trilobite 45mm, this excellently preserved trilobite, instantly recognisable by its distinctive constituent parts the very globose and inflated cephalon (head), the glabella (centre part of the head), granulose or covered with many tubercles situated between spindly or stalked eyes, the eyes sited on the glabella shield, again encrusted with tubercules or postules. Behind the cephalon shield protrude long glabella genal or cheek spines again these covered with many tubercules. A single thoracic spine longer again than its whole body length stretches from axial lobe or mid thorax lobe (segment L6), the sixth segment post the cephalon, this extends towards and over the pygidium (tail shield). The genal glabella spines are finely tapered and very long, these attached to the glabella lateral border field, resemble another trilobites diadem or semi circular coronet form of crown around the glabella border, the Diademaproetus's. However the Cyphaspis here having a more elongated genal cheek spine. The specimen is exceedingly good and fine. Painstakingly cleaned and removed from the matrix, or fossil bedrock.

Details

Some trilobites were pelagic swimmers, this trilobite Cyphaspis was a bottom seabed dweller, a forager its natant hypostome, which was a hard chitin mouth cover was a simple element, a muscle fixed cover which enabled the trilobite to sieve bottom silts filtering out organism to devour, as Cyphaspis dredged along the bottom. Its eyes being stalked helped it to see above the disturbance of its own forward motion.


The Cyphaspis trilobite fossilised on the original matrix (bedrock), has been extracted to show the ancient invertebrate crawl over its now fossilised seabed. The defensive...? Spines erect, the cheery character seemingly appears unaffected, as if the millions of years did not interrupt its daily foraging routine at all.

This trilobite was collected by one of our team members in North Africa and cleaned professionally in the Laboratory in Morocco. In the last decade the Moroccan preparitors have gained great skill cleaning and preparing trilobites, enabling top quality fossils to remain affordable, having a fraction of the cost of American or European Lab work. Having our association we have first hand knowledge of each specimen, guaranteeing the authenticity of our ancient arthropod, a member of the invertebrate group, a genuine fossil trilobite supplied with a certificate from The Fossil store. Cyphaspis: Order Proetida, Superfamily Aulacopleuroidea, Family Aulacopleuridae.
