This exceptional right leg of a large Allosaurus was unearthed in the Morrison formation of Wyoming and has been expertly prepared and mounted. The bone quality and completeness is also noteworthy with only a small number of bones in the foot being cast, and a minor section of the Femur. This museum quality specimen stands over 2.1 meters tall and is mounted on a high-end custom base.
AN INTRODUCTION TO ALLOSAURUS FRAGILIS
-
Allosaurus fragilis, a sizable bipedal dinosaur belonging to the Allosauridae family, earned its species name, "fragilis," due to its delicate, hollow bones that enhanced its agility and nimbleness. On average these dinosaurs reached lengths between 8.5 to 9.7 meters, and stood around 3.7 meters tall at the hips. Some isolated fossil discoveries however suggest these creatures might have even reached lengths of over 12 meters.
Allosaurus boasted a prominent skull and formidable serrated teeth, perfectly adapted for hunting and rending flesh. Notably, its skull featured pronounced brow ridges which added to a fearsome appearance. Forward-facing eyes provided crucial depth perception for effective hunting. Furthermore, robust hind limbs and a relatively lightweight tail contributed to its agility, establishing it as a formidable predator in its ecosystem. -
Allosaurus fragilis held a commanding position in the Late Jurassic food chain, preying upon herbivorous dinosaurs like Stegosaurus and possibly even Apatosaurus. Fossil evidence indicates a skilled and opportunistic hunter capable of taking down prey larger than itself.
The discovery of an Allosaurus specimen with an embedded Stegosaurus tail spike offers a glimpse into the intense struggles that unfolded in the ancient landscape. This evidence supports the theory that Allosaurus engaged in confrontations with well-armoured herbivores, showcasing a predatory prowess integral to its apex status. -
Recent paleontological findings shed light on the social behaviour and potential family life of Allosaurus fragilis. Fossilized bone beds containing multiple individuals suggest a degree of social structure, hinting at the possibility of cooperative hunting or communal nesting. These revelations challenge the conventional view of theropods as solitary predators.
-
The study of Allosaurus fragilis significantly enhances our understanding of dinosaur evolution and the ecological dynamics of the Late Jurassic period. As a member of the Allosauridae family, Allosaurus shares evolutionary connections with other notable theropods, offering valuable insights into the diversification and specialization of carnivorous dinosaurs during this era.
