Allosaurus is among the most recognizable of the American dinosaur genera.  It's slender build and feirce looking skull,with bony ornamentation above it's eyes, give it a distinctly menacing appearance.  The lower jaws are relatively  thin when compared with the upper and many scientists believe that it would have used it's strong neck and ferocious upper jaw in a hatchet-like attack when hunting prey. Three fingered-hands with large claws add to the terrifying effect, making allosaurus one of the scariest dinosaurs in our collection. Our specimen measures 22 feet long and is posed with it's head low enough for visitors to 'look it in the eye'. Allosaurus was a predator at the top of it's food chain in ancient Wyoming, Colorado, and Utah where it likely fed upon herbivorous dinosaurs like Stegosaurus. Our mount is often displayed along with the panel mounted skeleton of a dead Stegosaurus stenops to recreate a feeding scene.

Apatosaurus is one of the most celebrated members of the giant group of dinosaurs known as the sauropods. These animals walked on 4 huge legs and had long necks and tails which sometimes measured as long as a football pitch.  During the time of the American 'Bone Wars' when paleontologists were racing to publish more and more new species of dinosaurs from the American West, an exceptionally complete Apatosaurus post-cranial skeleton was incorectly described by O.C.Marsh as Brontosaurus, meaning thunder-lizard. Soon after this publication however, it was correctly assigned to the pre-existing genus Apatosaurus when scientists resolved that it the two specimens were from the same animal.  

Sauropods were the largest land animals that ever lived on our planet and their leg bones can be impressively long.  Our apatosaur femur drives this point home, measuring over 6' in length.

Stegosaurus is one of the most beloved herbivorous dinosaurs. This animal is easily recognized by the public due to it's distinctive double row of back armor and the long spikes on the end of it's tail.  The utility and function of these plates is the subject of much paleontological discussion, though most agree they would have served as a defense strategy among other uses like display or even thermoregulation. When you consider that this slow plant-eating dinosaur shared it's home environment with fierce predators like Allosaurus and others, the need for defense strategies becomes fairly obvious.  In 1992 this beloved dinosaur was named the state dinosaur of Colorado, where many important finds have been made.

Our specimen is mounted as a panel depicting the orientation in rigor mortis as it would have died.  This specimen is typically displayed horizontally on the ground, being fed upon by a mounted Allosaurus fragilus skeleton.  Specimen can also be hung vertically on a gallery wall in shows with a smaller footprint.
