THE FOSSIL STORE AES | Brass series brings you a Longianda termieri trilobite, now transformed with our elegant innovated-designed AES | Brass stands for spaces out there!The preservation afforded in the blue-grey limestone shales has left a wondrous result for this fine prehistoric fossilised invertebrate. The subtle colour palettes are created by minerals that have been absorbed for many millennia. Particularly here Copper has influenced the carapace preservation and bright green colouration to the plural spines of the right pleural lobes spines and the genal spine of the cephalon.   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...

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 Paradoxides acadoparadoxides briareus trilobite measuring 465mm held by the custom bronze mount, our classic range of specimens set into bronze 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 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 bronze 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 320mm, 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,...

A medium-sized and particularly nice coloured Cambropallas tellesto trilobite positive and negative fossil plate measuring 410mm including the bronze stand. This piece is of a very fine quality displaying great preservation throughout the plates, perfectly separated along the natural seamline of Iron oxide mineral concentrations, usually a red to brown and sometimes orange colour, affected by the iron oxide limonite. Iron oxide was concentrated along the cephalic margins, the thoracic and pygidial pleural spines, and at the articulating lobes of the thorax. These areas of the carapace (exoskeleton) were characterized by a tight fold called the doublure. The three-dimensional exoskeleton of the arthropod displaying every segment of the thorax, the cephalon (head) and pygidium (tail). The axis lobe running the length of the body from the cephalon to the pygidium raised in a dorsal keel fashion, the eye covers clearly protrude up from cephalon, each plural lobe complete and very...

A wonderful Paradoxides acadoparadoxides trilobite measuring overall 620mm, now surmounted on to a bronze mount, part of our classic range of specimens, elevated and set into bronze clasps, the specimen can be easily taken out for study. The specimen is unique. Every fossil is unique of course, however here the quality of preservation is of an apex collection piece. The preservation is of the highest grade; the trilobite plate is cleaved from a split nodule, this is entirely a regular happenstance.The exoskeleton carapace is in remarkable preservation all the essential features are here intact, the plate has not suffered the usual damage on the excavation. The constituent parts of the carapace are well defined here, the librigenes (cheeks) intact, long genal spines (situated from each side of the cephalon [head]) still in place and the thoracic segments (main body armoured segments) complete with spine terminations. The excellent pygidium (tail section)...
