	Photographs Description Price MOSASAURUS Mary the Mosasaur skull on display at the Tri-State Museum Add your content here Mosasaurus cf. missouriensis Skull and Partial Skeleton Butte County, South Dakota  FOR SALE reduced to $29,999.00             Offered for sale we have one ORIGINAL BONE Mosasaurus skull and partial skeleton legally collected from private ranch land in Butte County, South Dakota. This specimen is very nice with limited selenite gypsum damage (rare for Pierre Shale Formation specimens). The skull is 80-90% complete missing only the left surangular/articular, right pre-max, left pterygoid, left and right coronoid some teeth and small portions of the left quadrate, posterior-anterior portions of the maxillas and a few other minor bits and pieces. The partial skeleton consists of at least 10 paddle elements, one scapula, radius (?), four cervical vertebrae, atlas, axis, and a few other odds and ends. Several additional highly weathered dorsal vertebrae are also included with the specimen. Total length of the lower jaw is just over 30 inches (70 cm.). This places the length of the animal at its time of death somewhere between 21-24  feet long (7-8 meters).             The specimen is being offered partially prepared with minor restoration (crack fills and some teeth). It has also been set up with a temporary mount. Elements are loose and ready for study or molding/casting.   Specimen is offer for sale with FULL MOLDING AND CASTING RIGHTS (provided one mounted copy cast skull and cervicals is delivered to PaleoAdventures within one year of sale). A copy of all documentation, photographs, land-owner contract, partial publication rights, access to the dig site for research purposes and other miscellaneous information comes with the specimen and is included in the price. We anticipate this specimen to be one of the first, AAPS registered specimens (in progress).   The exact species of Mosasaurus is as yet, undetermined. Several experts argue that it is similar to Mosasaurus missouriensis, others suggest Mosasaurus conodon, and still others have suggested it may be a new un-described species of Mosasaurus. The specimen was found in the Didymoceras nebrascense ammonite zone of the Pierre (pers. comm. Neal Larson, 2005/2006), which does place it at an age somewhere between missouriensis and conodon (approximately 74-76 mya).    THIS SPECIMEN IS CURRENTLY OFFERED ONLY TO PRIVATE OR PUBLIC MUSEUMS, SCIENCE CENTERS, or ACADEMIC INSTITUTIONS/UNIVERSITIES IN THE CONTINENTAL UNITED STATES. There is a 10% discount for public institutions in the Western United States (ND,SD,WY, CO, UT, NM, AZ, TX, ID).
