蛋化石

化石,古代生物的遗体、遗物或遗迹埋藏在地下变成的跟石头一样的东西。研究化石可以了解生物的演化并能帮助确定地层的年代。保存在地壳的岩石中的古动物或古植物的遗体或表明有遗体存在的证据都谓之化石。从一古时候到现在都有化石出现。

Fossils, the remains, relics, or relics of ancient creatures buried in the ground and turned into stone-like things. Studying fossils can understand the evolution of organisms and help determine the age of the strata. The remains of ancient animals or plants preserved in the rocks of the earth's crust or evidence of the existence of the remains are called fossils. From ancient times to the present, fossils have appeared.

简单地说,化石就是生活在遥远的过去的生物的遗体或遗迹变成的石头。在漫长的地质年代里,地球上曾经生活过无数的生物,这些生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。在六随后的岁月中,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。

Simply put, a fossil is a stone made from the remains or remains of creatures living in the distant past. In the long geological age, countless creatures have lived on the earth, and 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 completely decomposed, and the hard parts such as the shell, bones, branches and leaves, together with the surrounding sediments, were petrified and turned into stone, but their original shape and structure (even Some subtle internal structures) still remain; similarly, the traces left by living creatures can also be preserved in this way. We call these fossilized biological remains and remains as fossils.

蛋化石是非常珍贵的古生物化石,最早于1869年发现于法国南部普罗旺斯的白垩纪地层中,由于在全世界范围内发现的蛋化石的数量不多。所见到的一般都是蛋的钙质外壳,极少发现保存有某种胚胎化石的蛋,很难判断所发现的蛋化石是由哪类生物产的。因此,在很长的一段时期内,有关蛋化石的研究工作并没有取得重要的进展。蛋化石群的保护贵在自然,贵在保持其原始状态。若将其从赋存的地质环境中挖掘出来,就会大大地丧失其科学价值和其它价值,而本藏品保存完整具有很高的研究价值以及收藏价值是难得一见的藏品

Egg fossils are very precious paleontological fossils. They were first discovered in the Cretaceous strata of Provence in southern France in 1869. Because there are not many egg fossils found worldwide. What you see is generally the calcareous shell of eggs. Eggs with some kind of embryo fossils are rarely found. It is difficult to tell which type of organism the egg fossils found are produced. Therefore, in a long period of time, the research work on egg fossils has not made important progress. The protection of the egg fossil group lies in nature, but in keeping its original state. If it is excavated from the existing geological environment, its scientific value and other values will be greatly lost. The complete preservation of this collection has high research value and collection value is a rare collection.
