Huge, 15.4" Triassic Amphibian (Metoposaurus) Clavicle Bone - Arizona
This is an absolutely massive, 15.4" long clavicle bone of Metoposaurus, collected from a private ranch, located on the Chinle Formation of northeast Arizona. The Chinle Formation is Upper Triassic in age, meaning this fossil is approximately 220 million years old. The preservation of the bone is excellent, with incredible details remaining across the entire specimen. It comes from the right side of the body and would have articulated with the interclavicle and posterior end of the left clavicle, combined to make up the pectoral girdle. Our estimation is this came from a Metoposaur that would have been nearly 14 feet long!
It comes with a custom metal display stand.
There is a section of restoration along the posterior edge that covers roughly an 8" x 2.3" wide area. The remaining repair/restoration is in the form of crack repair and gap fill which was required to piece the bone back together.
An artists reconstruction of what a Metoposaur may have looked like.
Metoposaurids were the ginormous ancestors of modern amphibians that managed to survive the Permian-Triassic extinction. These salamander-like creatures approached five feet in length on average, though they may have grown up to nine feet long. These amphibians are characterized by their broad, flat skulls, long limbs and paddle-like tails. Metoposaurs probably competed at the same feeding level with Phytosaurs, having very similar life styles and feeding strategies. Imagine a six-foot salamander that behaves like a crocodile, and you have a mostly accurate picture of Metoposaurids.
