TYRANNOSAURUS REX DINOSAUR BONE FRAGMENT WITH CHARACTERISTIC INNER STRUCTURES Hell Creek Formation - Montana, U.S.A. LATE CRETACEOUS PERIOD: 70 - 65 million years ago TYRANNOSAURUS REX bones are typically the most expensive dinosaur bones on the public market due to the demand and notoriety of the creature. Unfortunately, most bones are beyond the financial reach of collectors, even ones that are embarrassingly bad in appearance. Our 2005 digging season yielded us some large and impressive T. rex finds which we will offer later. On one of the sites, we collected a few fragments of bone that had already been exposed to offer our customers as affordable reference specimens of genuine Tyrannosaurus rex bone. While most dinosaur bone fragments CANNOT be honestly attributed to a species with certainty, there is a unique quality that the skeleton of T. rex possesses. The bones have a dense outer layer with an unmistakable "honeycomb" pattern to the inner cellular structure. This wonderful bone fragment of Tyrannosaurus rex displays this well making it one of the most affordable GENUINE TYRANNOSAURUS REX fossils one could own.
The name TYRANNOSAURUS REX is synonymous with sheer terror. Just mention the name and almost anyone, regardless of how much or little they know about paleontology, will recognize the "Tyrant Lizard King". Long thought to be the largest meat-eating dinosaur that ever lived, it has been recently discovered that Carcharodontosaurus (Giganotosaurus) was actually larger but not as robust as T. rex. Clearly, the massive proportions and musculature of Tyrannosaurus rex were meant for one thing, taking down anything that challenged it or got in its way! WARNING: Beware of dealers offering fragmented bones and teeth as being from T. rex. Ignorance and deception persists in the fossil trade as the financial rewards are great for wrongly classifying a fossil as from T. rex. Deal ONLY with reputable and knowledgeable suppliers who will provide a certificate and lifetime guarantee of positive identification.
The jaws
of a Tyrannosaurus rex were up to 4 feet long. Each dinosaur
possessed approximately 50 to 60 robust, conical teeth that ranged in
size from an inch to over 9 inches long. These teeth were rounder
in cross-section
Clearly, the sheer robustness of Tyrannosaurus rex required enormous amounts of protein to sustain such body mass. True scavengers tend to be lean with wiry, lighter bodies able to function better between the discovery of carcasses in the wild. Active predators will usually scavenge a carcass as a 'target of opportunity' which T. rex most probably did, but the mighty design of T. rex would have been both - 1) unnecessary up against prey that is not alive to fight back and, 2) of a body mass difficult to sustain over the lifetime of the beast on the availability of carrion, alone. Fossil remains of T. rex represent the pinnacle of dinosaur fossil collections and exhibits the world over. Their universal appeal and rarity compared to ever-increasing market demand put fine quality Tyrannosaurus rex fossils at the forefront of highly promising INVESTMENT FOSSILS. UNMISTAKABLE T. REX BONE WITH UNIQUE INNER CELL STRUCTURE - PERFECT FOR EDUCATIONAL REFERENCE! 3.75" x 2.25" overall SOLD DB18-003 INCLUDES STAND Actual Item - One Only |

TYRANNOSAURUS
REX grew to up 46 feet long, 20 feet high at the hips and weighed 5 to 7
tons. Despite some claims as to this beast being a clumsy
scavenger, the undeniable facts about T. rex's anatomy indicate quite
the opposite. This enormous killer was built to HUNT.
It had amazing senses for smelling (based on braincase studies and
enlarged lobes for this sense) but more importantly, Tyrannosaurus rex
was HIGHLY DEVELOPED for seeing - something you do not
need when all you "chase" after is a non-moving, dead animal. The
massive five foot skull had 4 inch diameter eye sockets that would have
held a 3 inch diameter eyeball. T. rex possessed
large lobes in its
brain for vision that processed complex sight information. T. rex
also had a unique head compared to most predatory dinosaurs with both
eyes facing forward on the front of its skull. This allowed ideal
depth perception - best needed for stalking and hunting LIVE, running
prey. While other predatory dinosaurs possessed depth perception,
it would not have been as developed as T. rex because of this feature.
Plant-eating dinosaurs have their eyes located on the sides of their
heads which allows them to WATCH FOR PREDATORS from all
directions, something T. rex never needed since it was THE king of
predators and had NO equal in its region.
than
most other predatory dinosaurs' teeth which enabled T. rex's teeth to
better stand up to crushing bone. Conical teeth can also best
sustain the impact force of hitting the body of its prey when attacking
and holding struggling prey prior to the kill. A similar conical
dentition is seen in
