RARE
GRADE PARADOXIDES TRILOBITE
Anti-Atlas Mountain Range, South Morocco
CAMBRIAN
PERIOD: 543 - 510 million years ago From
a very rare Anti-Atlas Range discovery of a small cache of superb grade
Paradoxides, this specimen is one of the very few of the finest of that
group that we have left. The occurrence of this find happened
several years ago and realizing a lifetime opportunity was at hand, we
secured the entire group which totaled just over 100 specimens including
about a dozen multiple examples. The majority of the lot have been
sold, many going to university, state and national museums around the
world. At the time of this posting, we still have a few superb
grade examples left including some multiple examples posted on other
pages in the
Paradoxides
section.
WARNING:
The
Paradoxides trilobite is one of the most popular fossils to fake and
every fossil shop, online auction and fossil show will invariably
present several for sale. Whether ignorant or just plain crooked,
very few sellers will HONESTLY AND CORRECTLY disclose if the Paradoxides
they offer is a complete fake or mostly restored. Any educated
buyer will agree this is a stigma with this species despite it being one
of the most impressive display fossils and the largest trilobite that
ever existed in the Cambrian. This
remarkable Paradoxides can boast of having
only
7% - 8%
restoration mainly on
the right genal spine, cheeks and some tips of the pleural spines with
some cracks filled on the body. Close up images show
detail and features rarely if ever seen in this type. The
vast majority of Paradoxides specimens on the market are either heavily
restored or completely fabricated. This is due in part, to the
destructive nature of the extraction of these type of fragile shale
limestone Cambrian fossils. Most are destroyed or severely broken
necessitating EXTENSIVE restoration. This specimen is a rarity
and offers an opportunity to acquire a quality never seen yet at a price
comparable to commercial gallery specimens. If you appreciate and are willing to
invest in a rare high grade example, then do not pass up this rare opportunity
to add to your collection a quality of Paradoxides that exceeds most
public collections and exhibitions.
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.
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'.
