Scientific name: †Ursus spelaeus (Rosenmüller, 1794) - Cave Bear - "Upper Jaw" Maxillary Molar Tooth (M2) Location: Cave located in Poland Geological Formation: Found in the sediments of a deep Cave or cavern Age: Late Pleistocene, Quaternary period (~50.000 Years) Size: 4,42cm long Ref: S235 Observations: Impressive "Upper Jaw" maxillary molar tooth (M2) belonging to the famous and enormous Ice Age cave bear (Ursus spelaeus). Completely natural, without restorations or repairs. Only a colorless professional stabilizer called Paraloid B72 has been applied to ensure its proper preservation. These types of teeth, found inside caves, have been exposed to extremely high humidity levels for thousands of years. When they are unearthed from the caves, the moisture within their structure begins to evaporate, and they dehydrate rapidly, leading to fracturing and rapid degradation of the fossil. For this reason, it is important to apply this professional lab paleontological protection. Teeth and bones that fossilize inside caves usually display beautiful dark, bluish, and highly varied colors. This is because mineralized water containing iron and manganese oxides circulated in the sediments where they fossilized along thousands of years. These oxides also percolate into the structure of the bones and teeth, mineralizing them. Sometimes, most of these colors are due to pyrolusite (manganese oxide). All our fossils come with Certificate of Authenticity. Every week, the issued Certificates of Authenticity are updated in our website database verification system. If you find that your certificate has not yet been updated, please contact us and we will update it immediately. Beautiful dome Display included.
