【简介】
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（海螺化石）、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。
此组生物化石，是一种海洋类古生物化石。海螺到了白垩时期，它们的种类急剧下降，由于地球地质的变迁，其残骸沉积在灰岩，身体的标本得以完整保存，年代久远变成了化石，且约在1/1000万才有形成化石的可能，可见这此海螺化石来之不易。
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。
【 introduction 】
Fossils are rare treasures that have evolved over the millennia and billions of years. They are important scientific specimens in the history of biological and human evolution. They are precious scientific and cultural heritage in the world and have great collection value.
Among the fossils of ancient marine life, the oldest fossils are the mycoalgae and palaeoalgae stromatolites of the Proterozoic Jixian period of 1 billion to 800 million years ago. In addition, it is a large number of Paleozoic calcium carbonate sedimentary rocks., Among them are corals, sponges, ammonites(conch fossils), sea lilies, and brachiopods, gastropods and other organisms 300 million years ago. After these creatures died, they preserved the strata of their bodies. After great changes, they finally formed stones.
In the long Geological years, countless creatures had lived on the earth. Many of the remains of these animals after their death or traces of life were buried by the sediments of the time. In the following years, the organic matter in the remains of these creatures was decomposed, and hard parts such as shells, bones, branches, and leaves were fossilized into stones along with the surrounding sediments. But their original form, structure(even some subtle internal structures) still remain; Similarly, the traces of life left by those creatures can be preserved in this way. We call these fossilized biological remains and remains fossils.
This group of fossils is a marine fossil. When the conch reached the chalk period, their species dropped sharply. Due to the changes in the geology of the earth, the wreckage was deposited in limestone, the body's specimens were completely preserved, and the age became fossils, and it was only about 1/10 million. The possibility of forming fossils, It can be seen that this conch fossil has not come easily.
With the market for fossil collections, marine fossils are no longer just collections. Fossils are no longer a simple source for collectors and fossil investors. Fossils originated from his rarity and the hundreds of millions of years of specimens left over from the changes that occurred in the early days of the Upper Ice Age and became fossils. Therefore, fossils are not only research values. Because of his rarity and the market's assessment of them has been very high.
