Description
Rebbachisaurus Sauropod Dinosaur Tibia Limb Bone Fossil
This is a genuine Rebbachisaurus sauropod dinosaur fossil tibia limb bone from the famous Kem Kem Beds of the Tegana Formation, Kem Kem Basin, Morocco. Dating from the Upper Cretaceous, Cenomanian stage, this carefully chosen fossil represents a remarkable piece of dinosaur anatomy from one of North Africa’s most iconic fossil-bearing regions. Full sizing can be seen in the photograph, and the photo shows the actual specimen you will receive.
This fossil is supplied with a fully hand-signed Premium Certificate of Authenticity, giving collectors confidence that they are purchasing a genuine prehistoric specimen. It is an excellent addition for collectors of dinosaur fossils, Cretaceous fossils, Moroccan fossils, sauropod material, limb bones and natural history display pieces.
Geology and Age
The Kem Kem Beds of Morocco are world-famous for producing an extraordinary range of Upper Cretaceous fossils, including dinosaur bones, teeth, fish remains, crocodile fossils, pterosaur material, turtle fossils and other vertebrate remains. This specimen comes from the Tegana Formation within the Kem Kem Basin, a region dated to the Cenomanian stage of the Late Cretaceous, approximately 100 to 94 million years old.
During the Cenomanian, the Kem Kem region was very different from the desert landscape seen today. It was part of a vast river-dominated environment with channels, floodplains, sandbars and freshwater to marginal aquatic habitats. Seasonal rivers and shifting sediment systems created ideal conditions for the burial and preservation of bones from large vertebrates, including predatory dinosaurs, fish, crocodile-like reptiles and giant herbivorous sauropods.
Dinosaur Type and Classification
This fossil is attributed to Rebbachisaurus, a large sauropod dinosaur from the Cretaceous of North Africa. Sauropods were long-necked, long-tailed herbivorous dinosaurs and include some of the largest land animals ever to have lived. Rebbachisaurus belongs to the rebbachisaurid sauropods, a distinctive group within the wider diplodocoid lineage.
Genus: Rebbachisaurus
Family: Rebbachisauridae
Superfamily: Diplodocoidea
Clade: Sauropoda
Order: Saurischia
Class: Reptilia
The genus Rebbachisaurus was named by French palaeontologist René Lavocat in 1954. Rebbachisaurid sauropods are known from Cretaceous deposits in North Africa and other regions, and they are important for understanding the diversity and distribution of sauropod dinosaurs during the mid-Cretaceous.
Tibia Limb Bone Anatomy
This specimen is a fossil tibia limb bone, part of the lower hind limb. In living animals, the tibia is a major weight-bearing bone between the knee and ankle. In a sauropod dinosaur, this would have formed part of the powerful hind limb structure that supported the enormous body mass of the animal. Sauropod limb bones are typically robust, dense and strongly built, reflecting their role in carrying large, heavy bodies across ancient landscapes.
A tibia fossil is especially appealing to collectors because it represents a recognisable part of dinosaur anatomy rather than an isolated tooth or fragment. Limb bones give a direct connection to the size, movement and biology of the animal. This type of fossil helps demonstrate how large sauropods supported their weight and moved through Cretaceous environments.
Rebbachisaurus and the Kem Kem Ecosystem
Rebbachisaurus was a herbivorous dinosaur that would have lived alongside some of the most famous predators and prehistoric animals known from the Kem Kem Beds. The ecosystem included large theropod dinosaurs, crocodile-like reptiles, turtles, pterosaurs and abundant fish. This unusual concentration of large predators and aquatic animals has made the Kem Kem Basin one of the most studied and collected Cretaceous fossil regions in the world.
As a sauropod, Rebbachisaurus would have occupied a very different ecological role from the predatory dinosaurs of the region. Its long neck and plant-eating lifestyle allowed it to feed on vegetation, while its large body size offered some protection from predators. Fossil limb material from sauropods is highly collectable because it represents the massive skeletal framework of these impressive dinosaurs.
Authenticity and Display Quality
This is a genuine fossil specimen and includes a fully hand-signed Premium Certificate of Authenticity. The fossil has been carefully selected as a display-worthy collector’s piece, with the photograph showing the exact specimen supplied. This allows buyers to view the bone’s natural preservation, shape, surface texture, colour and overall character before purchase.
As with all genuine dinosaur fossils, natural cracks, mineralisation, sediment staining, repairs, stabilisation, matrix, surface wear and age-related features may be present. These are normal characteristics of authentic fossil bone and form part of the specimen’s geological history. This Rebbachisaurus sauropod tibia limb bone from the Kem Kem Beds is a highly desirable fossil for collectors seeking a genuine Cretaceous dinosaur bone with strong scientific, geological and display interest.
