Description
Genuine Camarasaurus lentus Dinosaur Rib Fragment Fossil
This listing is for a genuine Dinosaur Camarasaurus lentus rib fragment fossil from Utah, USA, supplied with a metal display stand. This impressive specimen comes from the Morrison Formation, one of the most famous dinosaur-bearing formations in North America, and dates to the Upper Jurassic Period. It is a carefully chosen fossil piece with strong display appeal, ideal for collectors of dinosaur fossils, Jurassic fossils, sauropod bones, Morrison Formation specimens, and genuine prehistoric natural history items.
The fossil shown in the photographs is the actual specimen you will receive. Full sizing and scale can be seen in the listing photos. The metal stand makes this a highly attractive display piece for a fossil cabinet, desk, study, educational collection, museum-style display, or natural history room.
Fossil Type, Species and Classification
Camarasaurus lentus was a large herbivorous sauropod dinosaur, part of the group famous for their long necks, long tails, column-like limbs, and massive bodies. Camarasaurus is one of the best-known sauropods from the Morrison Formation and is especially valued by collectors because of its strong association with the classic Late Jurassic dinosaur faunas of the American West.
Camarasaurus belongs to Sauropoda, the great long-necked dinosaur group, and is placed within the family Camarasauridae. The genus Camarasaurus was formally named by Edward Drinker Cope in 1877, while the species lentus was originally described by Othniel Charles Marsh in 1889. Camarasaurus lentus is recognised as one of the smaller and more gracile species within the genus, although it was still a very large dinosaur by modern animal standards.
This specimen represents a rib fragment, part of the skeletal structure that would have helped support and protect the body cavity. Sauropod ribs were large, curved bones that formed part of the torso, supporting the chest and helping define the shape of the animal’s massive body. Fragmentary dinosaur rib fossils are highly collectable because they preserve genuine skeletal material from one of the largest land animal groups ever to exist.
Morrison Formation, Utah, USA
The Morrison Formation is world-renowned for producing some of the most iconic Jurassic dinosaurs, including Camarasaurus, Diplodocus, Apatosaurus, Allosaurus, Stegosaurus, and Ceratosaurus. Fossils from this formation are especially desirable because they represent one of the richest and most studied dinosaur ecosystems of the Late Jurassic.
This Camarasaurus lentus fossil comes from Utah, USA, a region famous for beautifully preserved Morrison Formation dinosaur remains. The formation spans much of the western United States and records a vast ancient landscape that existed during the Late Jurassic, approximately 145 to 156 million years ago. Utah has produced many important dinosaur discoveries from Morrison Formation rocks, making fossils from this area especially appealing to collectors and educators.
Upper Jurassic Geology and Ancient Environment
During the Upper Jurassic, the Morrison Formation represented a broad inland environment made up of river systems, floodplains, seasonal wetlands, lakes, ponds, and semi-arid plains. Sediments were deposited by ancient rivers and flood events, gradually burying dinosaur bones, plant material, and other remains in layers of sandstone, siltstone, mudstone, and clay-rich deposits.
The environment supported a diverse prehistoric ecosystem. Large herbivorous sauropods such as Camarasaurus browsed on Jurassic vegetation, while armoured dinosaurs, plated dinosaurs, small reptiles, early mammals, crocodile-like animals, fish, invertebrates, and predatory theropods shared the landscape. The fossilisation of dinosaur bone in the Morrison Formation often occurred when skeletal remains were rapidly buried by river or floodplain sediments, protecting them from complete destruction and allowing mineral-rich groundwater to gradually replace the original bone structure.
Morphology and Display Features
This fossil preserves part of a rib from Camarasaurus lentus, a genuine piece of sauropod dinosaur anatomy. Rib fragments can show natural curvature, dense fossilised bone texture, internal structure, weathered edges, mineral staining, and surface features created by both biological growth and geological preservation. As a natural fossil, it may display cracks, repairs, matrix traces, colour variation, and irregularities that are consistent with authentic dinosaur bone.
The included metal stand enhances the fossil’s presentation and allows the specimen to be displayed as a striking freestanding piece. It is well suited for anyone interested in genuine dinosaur bone, Jurassic fossils, sauropod fossils, Morrison Formation fossils, Utah fossil specimens, or natural history display items.
Certificate of Authenticity
This 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.
A Collectable Sauropod Dinosaur Fossil
A genuine Camarasaurus lentus rib fragment from the Morrison Formation is a desirable addition to any fossil collection. It combines an iconic Jurassic dinosaur, a famous North American geological formation, a classic Utah locality, and an attractive metal display stand. This specimen offers a tangible connection to the sauropod-dominated landscapes of the Upper Jurassic and makes an excellent choice for collectors, dinosaur enthusiasts, educators, and anyone looking for an authentic prehistoric display fossil.
