Zlichovaspis hausmani Trilobite 137mm


Availability:Out of stock


An archetypal and superb specimen Zilchovaspis; the re-named (formerly Odontochile) fossil arthropod worked out of the naturally formed bedrock block, this matrix is the original fossil bedrock, the age of which is around 390 million years ago. The trilobite entombed in the silts of that time which hardened into solid limestone. The articulation of the remaining fossil carapace (exoskeleton) is exceptional and comprehensive, showing the constituent parts of the carapace, of the once living invertebrate.

A Zilchovaspis trilobite prepared in the fossil preparation laboratory using pneumatic tools and finished with an air abrasive micro sand-blaster. This Trilobite is a Devonian Arthropod, a sea bottom dweller. This genus is known for its large eyes, long genal thoracic spines and terminal pygidium (tail) spike, in this variety this is short and stout. The trilobite has been prepared to expose the exoskeleton while retaining a prostrate stance on the original matrix (fossil limestone bedrock).

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).
