Articulated Mosasaurus paddle measuring approximately 70 cm in height and 30 cm in width. The specimen preserves a well-aligned and coherent series of phalanges and associated paddle elements, clearly illustrating the functional anatomy of the bones. Collected from the phosphate deposits of Khouribga, Morocco, dating to the Late Cretaceous period (approximately 70 million years old). The fossil has been professionally prepared and stabilized, with good bone definition and a balanced, natural presentation. The specimen is mounted on a custom-made metal stand, designed specifically to support and display the paddle securely while maintaining a clean, understated appearance. Articulated paddle sections of this size are uncommon on the market and represent a valuable and scientifically informative fossil, suitable for serious private collections or institutional display. A solid, authentic piece with lasting collectible value.
