化石拍卖（收藏家内饰）

美丽的板面，展示来自摩洛哥的多枚直角螺盾化石（Orthoceras）。这些古代海洋生物是地球上最早的生命形式之一。是在西北撒哈拉发现的。
Orthoceras 是已灭绝的头足类软体动物，属于一个早已消逝的群体。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。它们的名字在希腊语中的意思是“直角的角”，指的是它们壳的显著拉长、圆锥形状。壳被腔室分隔，由一个中央导管相连。
Orthoceras 壳是它们最具特征的特征。它由文石（一种与许多现代软体动物壳中也存在的矿物）组成。随着时间的推移，经过地质过程如沉积和矿化，这些壳化石化，形成了我们今天欣赏到的标本。
Orthoceras 化石是研究古海洋生物的重要见证。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，并洞悉塑造地球历史的重大变迁。

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.
