giant Paradoxides trilobite is the largest Cambrian trilobite that
is found in sedimentary rock beds from this period. These
kind of trilobite fossils often fracture when rock is split to locate
them. This unavoidable damaging method often leaves missing pieces
and highly fragmented specimens left to assemble and restore.
very large example is a fine quality specimen that far exceeds typical commercial
quality examples. It retains a majority of the original trilobite
with exceptional preservation and completeness. Close-up image of
body shows the presence of highly rare genuine detail
that very few examples can boast of having. Notice the distinct
original carapace still present. Approximately only 20%
restoration mainly limited to the genal spines and sides of the head as
well as pleural fringe spines. A high quality and very impressive specimen for collectors

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.
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
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.
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.
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
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.
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'.
