A fragmented marine reptile’s humerus bone consisting of the lower section of the humerus. This paddle bone, potentially from a Plesiosaur, would have been part of the front two limbs as a connection between the shoulder and the flippers. Many bones would follow afterwards forming the large fins allowing these reptiles to be such strong swimmers. Due to evolution, the flippers became the main feature for swimming rather than the tail. This particular bone has been preserved remarkably well with the bone’s original texture still visible.
Date: Circa 140 years ago million years ago Period: Late Jurassic Provenance: From a Surrey gentleman's collection (DG), purchased on the London Art Market from an ADA member, formed 1990's onward. Condition: Fine condition.
Plesiosaurs were large marine reptiles, first appearing around 200 million years ago. They have been found globally across different oceans. Plesiosaurs were distinguishable by their small head, long, slender neck and their two pairs of large elongated paddle flippers. The neck constituted for nearly half of the animals body comprising of over seventy vertebrae. These animals grew to be four meters long and had very sharp teeth for their Carnivore diets. Even though plesiosaurs spent most of their time in the water, they breathed air and would have to come to the surface for it. Plesiosaurs became extinct, along with all other avian dinosaurs, around 66 million years ago, in the Cretaceous-Paleogene extinction event. This was thanks to an asteroid colliding into earth.
