Scientific name: †Ursus spelaeus (Rosenmüller, 1794) - Ice Age Cave Bear - Claw bones - Set of 2 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 (the biggest): 3,9cm REF.: #S663 DESCRIPTION: Observations: Impressive claws 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 bones, 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. All of our fossils come with a Certificate of Authenticity. Every week, the issued Certificates of Authenticity are updated in our database verification system on our website. If you find that your certificate has not yet been updated, please contact us and we will update it immediately. Display box included.
