【简介】

化石是生物的遗体、遗迹，其不可再生性决定了其珍贵性，它们的发现对于古地质变迁和古生物进化、演变、灭绝的研究都具有重要价值。远古海洋生物化石中，最古老的化石是距今10亿——8亿年的元古代蓟县纪的菌藻、古藻类叠层石岩，除此之外，就是大量的古生代碳酸钙质沉积岩，其中有三四亿年前的珊瑚、海绵、菊石、海百合生物，还有腕足类、腹足类等生物。这些生物死后，保存了它们躯体的地层，经过沧桑巨变，才最终形成了石头。在漫长的地质年代里，地球上曾经生活过无数的生物，这些动物死亡之后的遗体或是生活时遗留下来的痕迹，许多都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的痕迹也可以这样保留下来。我们把这些石化了的生物遗体、遗迹就称为化石。藏品具有独特的历史意义，因此也极具收藏价值。

【 Introduction 】

Fossils are the remains and relics of living creatures, and their non-reproducibility determines their preciousness. Their discovery is of great value to the study of paleogeological changes and paleontological evolution, evolution and extinction. Fossils of ancient Marine fossils, the oldest is 1 billion - 800 million years ago the proterozoic jixian ji algal-bacterial laminated rock, ancient algae, in addition to this, is a lot of Paleozoic carbonate sedimentary rocks, including 3.4 billion years ago the corals, sponges, ammonites, sea lilies, and brachiopods, snails and other creatures. When these creatures died, the layers that preserved their bodies underwent great changes before they finally formed stones. In the long geological time, the earth has lived countless creatures, these animals after the death of the body or left traces of life, many are buried in the sand. In the years that followed, the organic matter in the remains of these creatures dissolved away, and the hard parts -- shells, bones, branches and leaves -- were fossilized into stone along with the surrounding sediments. Similarly, the traces left by those creatures can be preserved in this way. We call these petrified biological remains and remains fossils. The collection is of unique historical significance and therefore of great collection value.
