在漫长的地质年代里，地球上曾经生活过无数的生物，这些生物死亡后的遗体或是生活时遗留下来的痕迹，许多被当时的泥沙掩埋起来。在随后的岁月中，这些生物遗体中的有机物质分解殆尽，坚硬的部分如外壳、骨骼、枝叶等与包围在周围的沉积物一起经过石化变成了石头，但是它们原来的形态、结构（甚至一些细微的内部构造）依然保留着。同样，那些生物生活时留下来的痕迹也可以这样保留下来。我们把这些石化的生物遗体、遗迹就称为化石。

化石，从表面看只是石头而已，但深入审视，其中蕴藏着许多万物造化的天然信息密码，蕴藏着科学和艺术的内涵，所以，从利用的角度讲，化石具有艺术观赏效果和美学上的鉴赏享受效果、科学内涵和文化底蕴，可令人们追溯生命之历程和自然历史的脚步。 

此件藏品重266.3g。呈现不规则形，其保存完整，品相上佳。该猛兽牙齿并不尖锐，大部分呈现化石状，也有小部分没有石化，露出的钙质，犹如鲜活生命在跳动，似乎在诉说远古的故事。其色泽白色，大部分已经变黄，还有少许绿色，给予人古朴的气质。此藏品保留了原本的面貌，历史痕迹明显，牙齿上纹路清晰，具有极高的艺术价值与收藏价值。

In the long geological age, countless creatures have lived on the earth. Many of the remains of these creatures after death or the traces left over from their lives were buried by the sand at that time. In the following years, the organic matter in the remains of these creatures was decomposed, and the hard parts such as the shell, bones, branches and leaves were petrified into stone along with the surrounding sediments, but their original shape and structure ( Even some subtle internal structures) still remain. Similarly, the traces of those living creatures can be preserved in this way. We call these fossilized biological remains and remains as fossils.

Fossils, on the surface, are just stones, but after in-depth examination, there are many natural information codes for the creation of all things, and they contain scientific and artistic connotations. Therefore, from the perspective of utilization, fossils have artistic appreciation effects and aesthetic appreciation. Enjoying the effects, scientific connotation and cultural heritage can make people trace the course of life and the footsteps of natural history.

This collection weighs 266.3g. It presents an irregular shape, which is intact and good in appearance. The teeth of the beast are not sharp, most of them are fossilized, and some are not petrified, and the exposed calcium is like living life beating, which seems to tell ancient stories. Its color is white, most of it has turned yellow, and there is a little green, giving people a simple temperament. This collection retains its original appearance, with obvious historical traces and clear lines on the teeth, which has extremely high artistic value and collection value.
