£ 60.00
Genuine Allosaurus fragilis Dinosaur Rib Bone Fragment FossilThis listing is for a genuine Dinosaur Allosaurus fragilis rib bone fragment
fossil from Utah, USA, supplied with a metal display stand. This excellent theropod dinosaur specimen comes from the famous Cleveland-Lloyd Dinosaur Quarry, part of the Morrison Formation, and dates to the Upper Jurassic Period. It is a carefully chosen fossil with strong display appeal, ideal for collectors of dinosaur fossils, Jurassic fossil bone, carnivorous dinosaur fossils, Allosaurus specimens, Morrison Formation fossils, Cleveland-Lloyd Dinosaur Quarry fossils, and authentic natural history display pieces.The fossil shown in the photographs is the actual specimen you will receive. Full sizing and scale can be seen in the listing photos. Presented with its metal stand, this genuine dinosaur fossil makes an attractive display piece for a fossil cabinet, desk, study, educational collection, museum-style display, or natural history room.Fossil Type, Species and ClassificationAllosaurus fragilis was one of the most famous predatory dinosaurs of the Late Jurassic and is one of the best-known large theropods from North America. It was a powerful carnivorous dinosaur with strong hind limbs, grasping forelimbs, sharp recurved teeth, and a skull adapted for active predation. Allosaurus belongs to the order Saurischia, suborder Theropoda, and family Allosauridae.The genus Allosaurus was formally named by Othniel Charles Marsh in 1877. The species Allosaurus fragilis is the best-known species of the genus and is strongly associated with the Morrison Formation, where it was one of the dominant predators of its ecosystem. The name Allosaurus means “different lizard”, referring to anatomical features that distinguished it from other dinosaurs known at the time, while fragilis refers to the relatively lighter construction of parts of the skeleton.This specimen represents a rib bone fragment, part of the skeletal framework that helped support and protect the body cavity. In theropod dinosaurs, rib bones formed part of the torso and contributed to the shape, strength, and flexibility of the body. A genuine Allosaurus rib fragment is a desirable piece of dinosaur anatomy, offering a direct connection to one of the most iconic Jurassic predators.Cleveland-Lloyd Dinosaur Quarry, Utah, USAThis fossil comes from the Cleveland-Lloyd Dinosaur Quarry in Utah, USA, one of the most famous dinosaur fossil localities in the world. The quarry is especially well known for its remarkable concentration of Allosaurus remains, making it one of the key sites for understanding this impressive Jurassic carnivore.The Cleveland-Lloyd Dinosaur Quarry is within the Morrison Formation, a world-renowned Upper Jurassic rock unit that extends across large areas of the western United States. The Morrison Formation has produced many legendary dinosaurs, including Allosaurus, Camarasaurus, Apatosaurus, Diplodocus, Stegosaurus, Ceratosaurus, and other prehistoric vertebrates. Fossils from this locality are highly collectable because they combine a famous dinosaur species with a historically important American fossil site.Upper Jurassic Geology and Ancient EnvironmentDuring the Upper Jurassic, the region that is now Utah was part of a broad inland landscape made up of river systems, floodplains, seasonal wetlands, ponds, lakes, and lowland habitats. The Morrison Formation was deposited in layers of sandstone, siltstone, mudstone, and clay-rich sediment, laid down by ancient rivers, floods, and quieter water settings across a changing prehistoric environment.The Cleveland-Lloyd Dinosaur Quarry is particularly notable for its unusual accumulation of dinosaur bones, with Allosaurus material especially abundant. The depositional setting has often been interpreted as a low-energy floodplain or pond-like environment where bones accumulated before being buried in fine sediment. Over millions of years, mineral-rich groundwater moved through the buried remains, gradually replacing and strengthening the original bone structure through fossilisation.Morphology and Display FeaturesThis Allosaurus fragilis rib bone fragment preserves genuine fossilised dinosaur bone from a large Jurassic theropod. Rib fragments can show natural curvature, dense fossil bone texture, internal structure, mineral staining, weathered edges, surface wear, and colour variation caused by ancient burial and mineralisation. These features give dinosaur bone fossils their distinctive appearance and make each specimen unique.As an authentic fossil specimen, it may display natural cracks, repairs, matrix traces, irregular edges, surface wear, and other features consistent with genuine fossil bone. The included metal stand enhances the presentation and allows the fossil to be displayed as a freestanding specimen, making it ideal for collectors looking for a genuine dinosaur bone fossil with an attractive and educational display style.Certificate of AuthenticityThis fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. The certificate provides reassurance that the item is an authentic fossil specimen and not a modern replica or cast.Collectable Jurassic Predator Display FossilA genuine Allosaurus fragilis rib bone fragment from the Cleveland-Lloyd Dinosaur Quarry is a desirable addition to any fossil collection. It combines a famous carnivorous dinosaur species, a world-renowned Utah locality, the classic Morrison Formation, and a display-ready metal stand. This fossil is well suited for dinosaur enthusiasts, fossil collectors, educators, natural history displays, and anyone looking for an authentic piece of Upper Jurassic dinosaur history.
