DESCRIPTION:

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.

观测：这枚“上颌”臼齿（M2）属于著名且巨大的冰河时代洞穴熊（Ursus spelaeus）。完全天然，无任何修复。仅涂覆一种无色的专业稳定剂Paraloid B72以确保其妥善保存。此类牙齿在洞穴中发现，数千年来暴露在极高的湿度环境下。当它们从洞穴中被挖出时，结构中的水分开始蒸发并迅速失水，导致裂隙并快速退化化石。因此，采用这类专业的实验室古生物保护措施十分重要。

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).

在洞穴内化石化的牙齿和骨骼通常呈现出美丽的深色、蓝紫色及多样的色调。这是因为在它们化石化的数千年间，含铁和锰氧化物的矿化水在沉积物中循环。这些氧化物也渗入骨骼和牙齿的结构中，使其矿化。有时，这些颜色的大部分来源是菱锰矿（氧化锰）。
