Distal Radius Fragment of Plesiosaur – Cretaceous, Madagascar This specimen is a distal (articular) fragment of a radius belonging to a plesiosaur, a large marine reptile that inhabited the Cretaceous seas. Collected from the fossil-rich phosphate beds of the Betiouka region near Tulear, Madagascar, the piece preserves the robust morphology and distinctive surface of the articular end, providing a clear glimpse into the limb anatomy of these iconic marine predators. Presented on a clear acrylic display base (included), this fossil represents a scientifically valuable and visually striking fragment—an authentic link to the fascinating world of ancient marine reptiles.
