Rare Camarasaurus Dinosaur Metatarsal Fossil Bone with Metal Stand, Morrison Formation, Upper Jurassic, Harding County USA

Description

Authentic Camarasaurus Dinosaur Metatarsal Fossil – Morrison Formation, South Dakota

This exceptional Camarasaurus metatarsal bone fossil originates from the world-famous Morrison Formation in Harding County, South Dakota, USA, dating to the Upper Jurassic Period (approximately 150–155 million years ago). The fossil is a genuine limb bone from one of the largest and most recognisable sauropod dinosaurs. Mounted on a custom metal stand, it is a rare and visually striking specimen that represents a tangible piece of Earth’s ancient history.

Geological and Stratigraphic Background

The Morrison Formation is one of the most significant dinosaur-bearing formations in the world, stretching across much of the western United States. It was deposited during the Late Jurassic, in a vast system of floodplains, river channels, and shallow lakes formed in a warm, semi-arid climate with strong wet and dry seasons. Sediments within the formation include sandstone, mudstone, and siltstone, which perfectly preserved the remains of the giant sauropods that once dominated this prehistoric landscape.

Fossils from the Morrison Formation are found in strata belonging to the Kimmeridgian to Tithonian stages of the Late Jurassic. These layers record an environment teeming with vegetation such as cycads, conifers, and ferns—providing abundant food for massive herbivores like Camarasaurus, Diplodocus, and Apatosaurus.

This metatarsal was discovered within fine-grained sandstone typical of floodplain deposits, where rapid burial by sediment allowed exceptional preservation. The specimen exhibits the dense cortical bone and gentle curvature characteristic of sauropod foot bones, with clear surface texture and fine mineralisation.

Camarasaurus – The Classic Jurassic Sauropod

Camarasaurus, meaning “chambered lizard,” was a large quadrupedal herbivorous dinosaur belonging to the family Camarasauridae, within the Order Sauropoda. Reaching up to 18 metres in length, Camarasaurus was distinguished by its short, box-like skull, spoon-shaped teeth, and massive columnar limbs adapted for supporting its enormous body weight.

This fossil represents one of the metatarsal bones from the hind limb, which formed part of the powerful foot structure that supported this giant dinosaur’s immense frame. The metatarsal bones of Camarasaurus were robust, slightly flattened, and expanded at both ends for articulation with the phalanges and tarsal elements. Their structure provided both strength and flexibility for movement across Jurassic floodplains.

Camarasaurus was widespread across western North America and is one of the most completely known sauropods. Its remains are found throughout the Morrison Formation, often alongside those of its colossal contemporaries. This bone reflects the strength and resilience of these remarkable creatures, whose skeletal anatomy has provided crucial insight into sauropod locomotion and evolution.
