COMPLETE UTAHRAPTOR HUMERUS
ARM BONE FROM THE LARGEST RAPTOR DINOSAUR THAT EVER LIVED
Mountain Formation - Utah, U.S.A.
CRETACEOUS PERIOD: 132 - 100 million years ago
Certainly, this offering will be remembered as one of the rarest and
most impressive dinosaur bones we will (or could possibly ever)
is a COMPLETE
humerus arm bone of the largest and most dangerous of all dromaeosaur
"raptor" dinosaurs, the UTAHRAPTOR. It is so
rare, aside from this
we have never seen
any other UTAHRAPTOR fossil of ANY kind with definitive
anatomical proof of being Utahraptor!
Here you have a complete major limb bone in spectacular preservation and
easily attributed to this massive predator of the Early Cretaceous.
Acquired years ago direct from the field collector in an unprepared
state, we performed all preparation of this
specimen in our lab so we can attest to exactly what work was performed.
bone was received complete but in pieces, many still entombed in
limestone. The bone was naturally jet black. It was
carefully reassembled and only a very small portion of one area on the
edge of the proximal end was restored as was a minor portion of the
extreme outer edge of the twisting medial ridge running up near the
proximal end. The bone has been internally stabilized and sealed
with all cracks filled but ridges of where these cracks were were left
visible for reference. There is a weathered, partially eroded
portion on the underside of the distal end and this was left as it was
found with no restoration. All told,
the restoration on this bone
amounts to a modest 1% only!
remains of Utahraptor are beyond words when it comes to rarity.
Since it was only discovered as recently as 1991, very little material
is known and in scientific collections. This is the FIRST TIME we
are aware of any Utahraptor fossils being available for public purchase.
is truly a TROPHY FOSSIL and the collection that this
specimen will ultimately end up in will immediately be elevated to an
extremely advanced level. Dromaeosaur "raptor" dinosaurs are a
household word with the general public when it comes to dangerous
dinosaurs. This specimen comes from the king of these legendary
killers of prehistory.
Many ignorant / unscrupulous fossil dealers arbitrarily assign
identifications to their fragmentary dinosaur fossils of all kinds in an
effort to please buyers and often fetch higher prices than the pieces
are worth. We see this ALL THE TIME. Less valuable dinosaur
fossils sold at higher prices because of fictitious identifications.
Examples include Ornithomimosaur claws sold as dromaeousaur claws,
Nanotyrannosaurus or Carcharodontosaurus fossils sold as
Tyrannosaurus rex, and fragmented or partial dinosaur remains being
specifically called certain species when it is SCIENTIFICALLY IMPOSSIBLE
to know what species of dinosaur it came from. Scientists will
confirm what we are saying here that a large number of dealers are
grossly misrepresenting their inventory either by obvious errors in
identification or by claiming species or types of fossils that are
IMPOSSIBLE to make such identifications due to the common resemblance
fossils have with numerous dinosaurs. This specimen is a carefully
researched specimen and is guaranteed to be accurately represented.
performed ALL the work to this specimen ourselves so we can accurately
and honestly disclose the nature and extent of the repair and
This is a very
important "PLUS" in the fossil business as almost all fossils have some
repair and/or restoration yet the work is NOT performed by the dealers
Purchasing specimens FROM THE ACTUAL PERSON OR PERSONS DOING THE
PREPARATION WORK is VITAL for you to know what you are getting.
Buying rare fossils from a seller that purchases from a broker and
simply echoes what they were told is the best way to get a mystery
fossil with no recourse to determine as to what kind of work has been
done. This kind of
flippant and rampant misrepresentation in the fossil market is one of
the key arguments the science community uses to discourage buying
fossils! To be sure
that what you are buying is accurately and honestly represented,
deal with a highly experienced professional who has first-hand
knowledge AND experience with regard to fossil preparation,
repair and restoration as well as SPECIFIC knowledge of the fossils they
are selling and WHAT EXACTLY WAS DONE TO THEM in the preparation and
UTAHRAPTOR, scientifically known as
was a massive dromaeosaur,
the largest of this dangerous family of predatory dinosaurs. This
creature lived during the Early Cretaceous Period, 132 to 100 million
years ago. Utahraptor is a very recent discovery. The first
remains were found as a fragmented skeleton in 1991 in the state of Utah,
(hence the name).
This swift predator was 23 feet in length, weighed 1100 pounds and was
armed with killing claws that EXCEEDED 9 inches!
Like other dromaeosaurs,
its skeleton features elongated bones, showing this carnivore was
capable of rapid mobility. Most notable in the discovery were its
enormous sickle-shaped killing claws, one on each foot. A
dromaeosaur this size and armed with such giant claws could have
attacked any dinosaur it chose to and easily inflicted mortal wounds to
the belly of prey much larger than its own enormous size!
were made famous by the well-known motion picture, "Jurassic
Park", as "raptors", a group of fascinating extinct
dinosaurs. Most raptors were about the size of a small dog.
Some stood as tall as a man like Deinonychus. Dromaeosaurs are theropods that possessed specialized
features: a well-developed slashing talon on their second toe, a stiffened
tail, and large grasping hands. The largest member of the
dromaeosaur family is the massive Utahraptor.
raptors specifically in the movie Jurassic Park were called
Velociraptors but were shown much larger than real Velociraptors.
The Jurassic Park raptors were actually modeled after Deinonychus, a
larger dromaeosaur than Velociraptors.
"killing claw" of raptors was a terrifying and incredibly
efficient weapon. As they moved, it was held off the ground.
When the muscles of the toe were contracted, the claw swept down
quickly, providing for a powerful slash that may have been able to
disembowel prey swiftly. The stiffened tail would have been good
to stabilize the body while the grasping arms and jaws held onto the
prey for balance. Although there is no conclusive evidence for
this, it has been suggested that raptors could have performed leaps onto
large prey and used all four limbs to rip wounds in them.
were ferocious predators that some scientists believe hunted in packs
and attacked much larger dinosaurs by slashing their underbellies.
It is also believed that they were similar to lions in predatory
behavior, preferring ambushes and quick chases using their high
maneuverability along with strategic pack-hunting tactics. A human
could be torn to shreds by a pack of raptors in less than 30
discoveries in China have shown feathered species existed. This has
revolutionized paleontologists' view of what not only these creatures
could have looked like when alive, but of possible plumage on other
therapod dinosaurs. Dromaeosaurs share other characteristics with
birds and theories now place these vicious predators as being the earliest
ancestors of birds. Dromaeosaurs first evolved in the Early
Cretaceous and survived right up to the end of the Late Cretaceous
suggesting they were adaptable and capable hunters, surviving such a
prolonged period yet, remaining virtually unchanged in overall design.
