Mass Extinction Fossil Ordovician Asaphus Trilobites

Lot 0110 Details

Description
Anti-Atlas Mountains, Morocco, Ordovician, ca. 485 to 443 million years ago. This is a NATURALLY OCCURRING mass death assemblage of these trilobites on their original matrix, prepared to expose fossils in their original pose as when buried. Unlike many Moroccan multiple trilobite fossils where the trilobites are artificially assembled on matrix, this remarkable specimen is 100% natural with all trilobites found together as shown in their natural positions. The topic of MASS EXTINCTION is always a fascinating subject and our Earth's prehistory is filled with many tragic events with evidence of fossils like this specimen to demonstrate the sobering effects of such an apocalyptic occurrence. None of the trilobites possess any artificial coloring or fabrication. The slab was removed from the formation in multiple large pieces and only necessary repairs have been made to the rock and cracks filled as is typical with all trilobite fossils. This grouping of very large Asaphus trilobites shows spectacular qualities of both complete and incomplete creatures. There are 4 complete trilobites with a complete 5th trilobite beneath one of the other 4. There are also scattered body parts of several other Asaphus trilobites naturally associated with these 5. The color is 100% natural on all of the trilobites. The standard color in this formation and location for these is black but the beautiful variations of orange is due to the presence of the mineral limonite, seen on several of the creatures' carapaces. Each trilobite is preserved in full inflation with incredibly well-preserved anatomy and form. The photos do not really demonstrate the extremely high relief and detail of this specimen. It resembles an interstate pile-up of automobiles with numerous trilobites overlapping one another in a scattered array. Many of these Asaphus trilobites display some of the best preservation and detail we have ever seen. Size: 21.5" L x 21" W (54.6 cm x 53.3 cm)

Trilobites are hard-shelled, segmented creatures that lived hundreds of millions of years ago in the Earth's ancient seas. They are considered to be one of our planet's earliest complex life-forms and are one of the key signature creatures of the Paleozoic Era. Trilobites went extinct before dinosaurs even existed. 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.
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 amongst 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. Trilobite fossils are collected by locating a fossil-bearing layer in rock and then breaking boulder or splitting rock sheet to reveal a cross-section of the preserved trilobite carapace in the break or to reveal an imprint in the sheet. Once the fossil is located, the pieces are then reassembled and delicate preparation then ensues to remove the surrounding rock above and around the trilobite to expose the fossil.
