We'll translate as Late Cretaceous. Here goes: For sale a magnificent educational and historical lot composed of three authentic fossil teeth from marine reptiles of the Late Cretaceous. The three specimens come from the famous phosphate deposits of Morocco and represent the incredible diversity of the predators that dominated the oceans more than 70 million years ago. Technical Data of the Lot • Era / Period: Late Cretaceous (Maastrichtian), approximately 72.1 million years ago. • Geological formation: Ouled Abdoun Basin. • Provenance: Oued Zem, Khouribga Region, Morocco. Individual Details of the Pieces: 1. Tooth of Globidens phosphaticus (Mosasaur with heavy dentition) • Length: 2.3 cm. • Description: A fantastic and highly characteristic specimen of this mosasaur specialized for crushing. Unlike other marine reptiles, its teeth evolved with a rounded, globose dome-shaped form, specifically designed to triturate the hard shells of ammonites, bivalves, and sea turtles. 2. Pterygoid tooth of Prognathodon giganteus (Mosasaur superpredator) • Length: 3.5 cm. • Description: A piece of enormous scientific and anatomical interest. The tooth bears only the carina on its posterior part, maintaining a rounded morphology at the front. This highly specific morphological feature strongly indicates that it is a pterygoid tooth (located on the palate/roof of the mouth), used by the animal to hold and guide prey toward the throat. It preserves a dark, intense color and a well-preserved enamel. 3. Tooth of Zarafasaura oceanis (Elasmosaurid plesiosaur) • Length: 5.5 cm. • Description: Impressive long, slender tooth of a long-neck plesiosaur. It shows the typical curvature and fine longitudinal striations on the enamel, perfectly adapted to catching slippery fish and cephalopods in the open ocean. 4. Fossil Bone Fragment of Mosasaurus (Piece / Multi-use Display Stand) • Dimensions: 8 x 6 x 6 cm. • Description: A solid block of matrix with a fossilized bone remain of Mosasaur. It features a magnificent internal trabecular bone texture, porous and of a very striking pale white/cream color. Because of its morphology and stability, this piece can be perfectly used as a natural and organic display stand to place on top the three dental teeth of the lot, creating a unique paleontological diorama in your display case.
