化石拍賣

极美的板材，展示来自摩洛哥的多枚Orthoceras化石。这些古老的海洋生物曾是地球上最早的生物之一。于西北撒哈拉地区发现。
Orthoceras是已灭绝的头足类软体动物，属于一个早已消失的群体。这些海洋生物在数亿年前的海洋中生活，主要分布在奥陶纪和志留纪时期。它们的名字在希腊语中的意思是“直角角角”，指的是它们壳体的细长圆锥形特征。壳体被分割成若干腔室，由隔板分隔，并通过一个中央的虹吸管相连。
Orthoceras壳是它们最具特征的特征。它由文石（方解石的一种）组成，这种矿物也存在于许多现代软体动物的壳中。随着时间推移，通过地质过程如沉积与矿化，这些壳体被化石化，形成了我们今天欣赏的标本。
Orthoceras化石是古代海洋生物的宝贵见证。对它们的研究使科学家能够重建史前生态系统，理解物种进化，并深入了解塑造地球历史的重大变革。

Bellissimo piastra con diversi esemplari di Beautiful slab featuring multiple Orthoceras specimens from Morocco. These ancient marine animals were among the earliest life forms to inhabit the planet. Discovered in the northwestern Sahara.
Orthoceras are extinct cephalopod mollusks belonging to a long-lost group. These marine creatures lived in the oceans hundreds of millions of years ago, primarily during the Ordovician and Silurian periods. Their name, meaning “straight horn” in Greek, refers to the distinctive elongated, conical shape of their shells. The shell was divided into chambers separated by septa and connected by a central siphuncle.
The Orthoceras shell is their most characteristic feature. It was composed of aragonite, a mineral also found in the shells of many modern mollusks. Over time, through geological processes such as sedimentation and mineralization, these shells fossilized, forming the specimens we admire today.
Orthoceras fossils are valuable witnesses to ancient marine life. Their study allows scientists to reconstruct prehistoric ecosystems, understand species evolution, and gain insight into the major changes that have shaped Earth’s history.
