A well-preserved, fully articulated Mosasaurus paddle section measuring approximately 60 cm in height and 30 cm in width. The specimen retains a clear series of metacarpals/metatarsals and phalanges, forming the functional flipper that powered this marine predator through Late Cretaceous seas. Collected from the phosphate deposits of Khouribga, Morocco, 70 million years old. The bones are naturally arranged, giving the piece a striking, almost hand-like appearance without feeling overly reconstructed. Professionally prepared and stabilized, the fossil shows strong anatomical clarity and surface detail. It presents well and is suitable for private collections or institutional display. Authentic articulated paddles like this are not frequently available on the open market. A refined, scientifically meaningful specimen that speaks for itself.
