08002 - Nicely Preserved 0.84 Inch Globidens phosphaticus (Mosasaur) Tooth on Matrix Cretaceous Calymene Calcite is a carbonate mineralNice unbroken specimen preserved in its natural phosphatic matrix. In the international market is very common to find Mosasaurus rests coming from the phosphate quarries of the Upper Cretaceous of the Ouled Abdoun Basin (Morocco). This quarries have been exploited since the beginning of the past century. Many sellers that sell this fossils do not make a good precise taxonomic identification work.
