An exceptional opportunity to own a fossilized and fully articulated Mosasaurus flipper (paddle) section, measuring an impressive approximately 60 cm in height. This remarkable specimen preserves the complete series of metacarpals/metatarsals and phalanges, forming the functional “hand” or flipper that once propelled this apex marine predator through the ancient seas. Collected from the renowned phosphate beds of Khouribga, Morocco, this fossil dates to the Late Cretaceous (~70 million years ago). While Mosasaurus material is relatively common from this locality, complete and articulated flipper sections of this size and quality are exceedingly rare and highly sought after by collectors. The bones have been carefully assembled, maintaining their natural integrity and anatomical accuracy. Each bone displays the rich texture and coloration characteristic of genuine fossilized Mosasaurus bone. The arrangement of the bones gives the specimen an almost lifelike, hand-like appearance — adding a fascinating aesthetic dimension and making it both a scientific and decorative centerpiece. This specimen is composed primarily of fossilized Mosasaurus bone, with some elements replaced by material from other individuals of the same species to complete the articulation. The result is a striking, display-ready fossil that beautifully illustrates the anatomy of one of prehistory’s most powerful marine reptiles. A true collector’s piece — ideal for museum display, educational purposes, or a high-end private collection, this flipper section represents both the scientific and visual grandeur of Mosasaurus evolution.
