MOROCCONITES
TRILOBITE LAB PREPPED
- Atlas
Mountains, Morocco
DEVONIAN
PERIOD: 395 - 345 million years ago
The
Morocconites malladoides trilobite was a bizarre creature of the ancient
seas. As the "unicorn" of the Devonian trilobites, this
wonderful invertebrate is quite rare in genuine form. Due to the
fragile nature of the projecting point off the cephalon, it is
common to recreate these by using putty or carving a fake one in the
rock and painting it black. The demand for authentic
Morocconites specimens is very strong and they are always in VERY limited supply.
We
guarantee the genuineness of the spine
and we proudly offer this rare trilobite with lab-preparation and
micro-blasting to the complete surface for exquisite
detail.
This fantastic example
displays a straight-on articulation making for a nice display. The overall surface is
good but with abrasion. Both eyes show tiny multi lens detail with
light nicks. Color is natural and host rock is original.
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'.
