化石是历经上千年、上亿年沧海桑田演变的稀世珍宝，是生物和人类进化史上具有重要意义的科学标本，是世界上珍贵的科学和文化遗产，极具收藏价值。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

随着市场对化石的收藏热度来看，海洋生物化石已经不是单单的收藏那么简单了，化石对于收藏爱好者和化石投资者来说已经源源不是简单的喜欢和研究那么简单了，化石源于他的稀有和对于上冰河时期地球早期所发生的变故而遗留下了的亿万年标本进而变成了化石，所以化石已经不单单是只有研究价值而已，因为他的稀有和市场对他们的评估已经是非常高。

Fossils are rare treasures that have evolved over the course of thousands of years and hundreds of millions of years. They are important scientific specimens in the evolutionary history of biology and human beings. They are precious scientific and cultural heritages in the world and have great collection value. Among the ancient marine biological fossils, the oldest fossils are the Protozoan Jixian period fungal algae and paleoalgae stromatolite rocks from 1 billion to 800 million years ago. In addition, they are a large number of Paleozoic calcium carbonate sedimentary rocks. Among them are corals, sponges, ammonites, sea lily creatures 300 to 400 million years ago, as well as brachiopods and gastropods. After these creatures died, they preserved the stratum of their bodies. Only after vicissitudes of life did they finally form stones.

In the long geological age, countless creatures have lived on the earth. Many of the remains of these animals after death or traces left in life are buried by the mud and sand of the time. In the following years, the organic matter in these biological remains was decomposed, and the hard parts such as shells, bones, branches and leaves, along with the surrounding sediments, were petrified into stones, but their original forms and structures (even Some subtle internal structures) are still preserved; similarly, the traces left by the living creatures can also be preserved in this way. We call these petrified biological remains and relics fossils

With the market's popularity for fossil collections, marine fossils are no longer as simple as collections. For fossil lovers and fossil investors, fossils are no longer as simple as liking and research. Fossils are derived from him. Rarity and the hundreds of millions of years of specimens left over from the early changes of the Earth during the Upper Ice Age turned into fossils, so the fossils are not only of research value, because of their rarity and market evaluation of them Is very high.
