MONSTROUS NEARLY 3
DEVONIAN SEA SCORPION EURYPTERID WITH 3-DIMENSIONAL DETAIL FROM GERMANY
ONE OF THREE KNOWN
DEVONIAN (EMSIAN) PERIOD: 407 - 397.5 million years ago
Over the many years of
collecting, preparing and offering a variety of fossil specimens that
surpass what most museums possess, there are some that will always remain
fondly in our memories. This specimen
most definitely will be one of them! It is an
(one of only three specimens like this are known to exist)
giant and complete prehistoric SEA SCORPION or also otherwise known as
an EURYPTERID. With most fossil eurypterids varying in length from
4 to 6 inches, this amazing specimen approaches 32 inches in length if
it were to be straightened. Scientists know that much larger
examples of these creatures existed despite the extreme rarity of
fossils of the larger varieties. In rare instances of finding
fossils of giant eurypterids, the majority of cases involve finding only
body parts or partial fragments of these creatures. Complete
specimens of these large prehistoric arthropods are seldom seen even in
scientific publications, not to mention museum inventories.
Collected several decades ago when it was legal to dig in the deposit
(long since closed and protected by the Germany government) and recently
prepared in our lab, this is a complete Early Devonian
fossil of a giant sea scorpion too rare to be accurately attributed to a
specific genus due to the scarcity of known specimens. It is one
of only three complete specimens of its kind we know of that exist.
One of the three is now in the national museum in Germany and this is
the better of the remaining two that are privately owned. Never
before have we witnessed a large eurypterid of this dimension and nature
being available for public sale and due to the deposit being protected
and closed to public collecting long ago, it is certain you will not see
one like it for sale ever again.
Lacking the necessary anatomy of the giant Pterygotus which
reached 2.5 meters, this specimen is likely a monstrous example of
another clade as Tetlie writes that most eurypterid clades could have
had creatures approaching 100 cm. The lack of claws and long
swimming appendages is unusual and not typical for most eurypterids.
It is not missing this anatomy in the fossil, but did not possess them
originally making this a type of a lesser seen variety. Based on
the presence of its segmented, pointed appendages rather than
paddle-shaped legs typically seen in swimming varieties, this anatomy
would seem to be designed for crawling on the bottom of a brackish
marine environment and possibly up onto dry land as is theorized, rather
than it be of a type more akin to swimming. The tail lacks a long
telson and the entire body is segmented with
excellent mineralization of
the carapace in its original colors of burnt gold, brown and orange.
Most impressive is the the multi-dimensional form of the fossil
and anatomy of this massive creature. Much of the body is raised
off the rock, especially the most posterior portion of the abdomen and
some of the appendages, as well as the head (cephalon). The color
is natural and the specimen has only restoration limited to filling in
of cracks as it was found in pieces and required repair that is typical
for such large fossils of this nature. The pose is slightly
distorted with the head bent backwards and one appendage appears to have
been folded beneath it when it was originally buried prior to
fossilization. Further information would be appreciated on this
specimen from qualified academic professionals.
Eurypterids are fascinating fossils and represent what many to believe
to be the first life-forms that progressed out of water onto dry land.
Museums that display eurypterids most commonly possess the typical small
varieties that are found still today from rich deposits like those in
New York, USA. It is certain that any institution that possessed
THIS spectacular specimen would make any and all its
visitors beyond impressed should it be put on display or
publicized in the media.
For such a rare and
invaluable example like this to be part of a public display, such an
acquisition would immediately elevate the prominence of such a
collection, without question. Not only does this fossil represent
a scientific keystone in the progression and variety of Earth's
life-forms and natural history, IT IS A REMARKABLY IMPRESSIVE FOSSIL TO
SEE IN PERSON and would surely be a central specimen in ANY collection.
For trilobite or other
fossil arthropod collections, this would definitely be one of the
central specimens of visitor interest in a public or private forum.
represents one of the most valuable and prized acquisitions a fancier of
natural history could ever hope to possess. Many rare fossils are
not visually impressive and many visually impressive fossils are not
is one of those prize discoveries that is BOTH!
EURYPTERIDS or SEA SCORPIONS
were aquatic arthropods that were highly efficient predators predating
the most primitive fishes. The largest known arthropods to have
ever lived were eurypterids. Eurypterids are believed to have
possibly had dual breathing capabilities in order to allow them to live
in water and also venture for short
periods of time onto dry land. Eurypterids are also scientifically
interesting fossils because they are believed to be related to a
found in Cambrian strata dating from
510 million years ago
demonstrating the first evidence of creatures emerging from water
to walk on land.
All eurypterids are extinct
and their fossil remains are found in deposits ranging from the
Ordovician Period to the Permian Period. Eurypterids are
crustacean-like creatures that had a chitinous exoskeleton similar to
trilobites. Also similar to trilobites, eurypterids are made up of
three fundamental regions - a head (CEPHALON or PROSOMA), a body
(ABDOMEN or OPISTHOSOMA) and a tail spike (TELSON or TERMINAL METASOMA).
The upper body and head are often combined in terminology to be called a
CEPHALOTHORAX and the main body called an ABDOMEN.
Eurypterids have compound
eyes and typically had six pairs of appendages found near the head.
The first pair were claws (although some varieties lacked claws),
followed by four pairs of walking legs and finally, a pair of swimming
appendages (also lacking in some varieties). Some types achieved
lengths of 2.5 meters but most were between 10 to 12 cm long.
