ULTIMATE RARITY COMPLETE UTAHRAPTOR HUMERUS ARM BONE FROM THE LARGEST RAPTOR DINOSAUR THAT EVER LIVED

Cedar Mountain Formation - Utah, U.S.A.

EARLY 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) offer. 

This 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 specimen, 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 EXTRAORDINARILY RARE specimen in our lab so we can attest to exactly what work was performed. 

The 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!

Fossil 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. 

This 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.

SPECIAL NOTE:  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. 

We performed ALL the work to this specimen ourselves so we can accurately and honestly disclose the nature and extent of the repair and restoration.  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 selling them.  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, only 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 restoration process.


UTAHRAPTOR, scientifically known as Utahraptor ostrommaysi, 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, U.S.A. (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!

Dromaeosaurs 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.  The 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. 

The "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.  

Raptors 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 seconds. 

Recent 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.
