THE FOSSIL STORE AES | Brass series brings you a beautiful specimen of a Gigantopygus sp. trilobite, now transformed with our elegant innovated-designed AES | Brass stands for spaces out there!The preservation afforded in the grey limestone shales has left a wondrous result for this fine prehistoric fossilised invertebrate. The subtle colour palettes, created by minerals that have been absorbed for many millennia, are concentrated along the cephalic margins, thoracic and pygidial pleural spines and articulating lobes of the thorax.  The exoskeleton of the arthropod displays every segment of the thorax; the cephalon (head) and the pygidium (tail). The axial rings of the axis lobe run the full length of the body from the first occipital lobe to the axial ring of the pygidium and are in excellent form for this particular type. - Each plural lobe is complete and very well-defined through to the pygidium. This is a firm favourite among us here...

A wonderful example of the Asaphus acadoparadoxides briareus trilobite measuring held by the custom brass mount, our classic range of specimens set into brass clasps. The specimen can be easily lifted off for study. An absolutely unique specimen with good preservation, the trilobite plate has formed nicely with care throughout preparation which has been evidently taken. A wonderful and natural specimen in such a condition elevates the trilobite to the top echelons in trilobite collecting from this location and time period.  The attractive colour is from the fossil bed. Heavy minerals cause the burnt umber colouration a byproduct of the heavy concentrations of iron in the region of the fossil bed and typical of this formation. This transpires as a dusty coating of fine limestone. Giving the fossil a most recognisable signature. The dark brass colour of the mounts complements the fossils. The process of fossilisation is best achieved in an...

THE FOSSIL STORE AES | Brass series brings you a positive and negative Cambropallas tellesto geode measuring 460mm, now transformed with our elegant innovated-designed AES | Brass stands for spaces out there!This extraordinary specimen offers a positive and negative example of the well renowned and exotic Cambropallas tellesto trilobite.Iron oxide concentrations have allowed for such a wondrous result of colour pallettes here, due to iron oxide limonite within the limestone, these minerals have been absorbed for many millennia, concentrated along the cephalic margins, thoracic and pygidial pleural spines and articulating lobes of the thorax - all these areas of the carapace or exoskeleton were characterized by a tight fold called the doublure. The three-dimensional exoskeleton of the arthropod displays every segment of the thorax; the cephalon (head) and pygidium (tail). The axis lobe runs the length of the body from the cephalon to the pygidium, which stands up elegantly at the tail-end,...
