LARGE SUPERB GRADE RARE NATURAL CHARCOAL BLACK ASAPHUS TRILOBITE Anti-Atlas Mountain Range, South Morocco ORDOVICIAN PERIOD: 510 million years ago This is a superb and very large specimen of an Asaphid trilobite. The inflation is fantastic and exhibits excellent high relief across the trilobite's body. The original carapace is present and has been fossilized in a natural color of charcoal black. Original limestone host rock is present and is quite thick and large making for an incredible display fossil. The matrix has been blasted smooth and fully cleaned and in a contrasting whitish gray, beautifully showcases this very large, naturally black trilobite. This extremely impressive specimen is entirely one animal and has not been composited or heavily restored which makes it truly a very rare specimen for this type. The entire creature is fully articulated and exhibits full inflation along with wonderful detail and preservation. The eyes are both genuine and intact, VERY RARE. The limestone slab is the original repaired host rock of the trilobite. Here's a seldom seen trilobite that makes a fantastic display fossil for it's rarity, natural condition and impressive size on its thick and original rock matrix. This trilobite type is surely to appreciate as the extremely limited supply continues to dwindle as evidenced by the already lack of fine examples found in today's market.
Next to dinosaur fossils, trilobites command a dedicated and passionate following amongst both scientists and fossil collectors, alike. In a relatively short time-frame (scientifically speaking, of course), we have the emergence and subsequent extinction of these fascinating creatures. Still most baffling is the incredible diversity of sizes and features that made up the trilobite group. Many bizarre species co-existed with highly specialized body parts that defy the theories of evolution in their "sudden" emergence and diversity during the Early Cambrian Period in what is known as the 'Cambrian Explosion'. Trilobites were among the world's first arthropods, a phylum of hard-shelled creatures with multiple body segments and jointed legs (although the legs, antennae and other finer structures of trilobites only very rarely are preserved). They constitute an extinct class of arthropods, Trilobita, that is comprised of over 15,000 known species. It has been reported that every year, four to five new species are discovered in the Atlas and Anti-Atlas Mountain regions in Morocco, alone! This desolate northern fringe of the Sahara Desert was once covered by a prehistoric ocean and its fossil deposits can be considered the world's richest and most diverse source of these ancient sea creatures. Trilobites are the single most diverse group of extinct organisms that ever existed, period! The smallest known trilobite is just three millimeters long, while the largest type grew to a length of 70 centimeters (over two feet long!). The most common fossil of trilobites is the mineralized dorsal exoskeleton of the creature. This is found in partial form from molting (shedding the shell as it grows) or in complete form when the animal was buried and died intact. The soft parts of the underside are rarely preserved. The name 'TRILOBITE' means 'three lobed" and is derived from the fact these animals had bodies featuring three longitudinal lobes, not lateral (head, body, tail) as is often thought. The lateral division of three parts is shared by many arthropods, not just trilobites. Considerable study has been done on trilobites as a whole organism. Even more fascinating though, is the research done on a microscopic level with regards to trilobite morphology. Radiographs have captured incredible detail of complete and fully articulated antennae and underparts like legs and gills, preserved in the host rock of some fossilized specimens. Perhaps the most impressive and classic feature of trilobites that comes to mind is the eyes. Microscopic studies of trilobite eye structures have also revealed marvelous adaptation and very high degrees of specialization in vision. It seems that the more we learn about trilobites, the unfolding of their mystery is stranger than fiction. Certainly we gain a greater appreciation with each new discovery of these strange and highly advanced but now extinct 'butterflies of the ancient seas'.
