Museum-Quality Mosasaurus Fossil. A well-preserved, fully articulated fossilized Mosasaurus paddle measuring approximately 60 cm in height and 30 cm in width. This exceptional specimen preserves a complete series of metacarps forming the fully functional flipper that propelled this prehistoric apex predator through the late Cretaceous seas. Collected from the phosphate deposits of Khouribga, Morocco, the fossil is 70 million years old. The bones are naturally arranged, giving the piece a striking, almost hand-like appearance. A refined, scientifically meaningful specimen that speaks for itself.
