美丽抛光菊石化石切片——自然的螺旋几何

这块惊艳的菊石化石切片展示了自然设计的永恒之美。经切割与抛光，揭示其错综复杂的内部腔室，色调温暖，呈琥珀色、蜂蜜色与奶油色，并带有自然形成的晶体与矿物质纹理。螺旋图案锐利而醒目，十分适合用于家居装饰、收藏柜陈列，或作为给化石爱好者的独特礼物。

这是属于菊石的已灭绝头足类软体动物。它生活在上侏罗世（约1.72亿至1.49亿年前），其化石遍布全球各大洲。
这些是海生动物，其外壳主要由碳酸钙以文石型形成，部分由一种有蛋白质特性的有机物（壳质丝）构成。壳内被隔板分成若干腔室，软体动物仅占据最后一个（生腔）。其他腔室，即充满气体的裂腔部分（壳室），用于调节生物的浮力。腔室液体的压力由一根细长、丰富血管化、部分矿化的管状有机结构（虹吸管）控制，贯穿所有隔板，允许通过渗透作用使动物的血液和软组织与腔室之间实现体液交换。

Beautiful Polished Ammonite Fossil Slice – Natural Spiral Geometry -
This stunning ammonite fossil slice showcases the timeless beauty of nature’s design. Cut and polished to reveal its intricate internal chambers, the piece displays warm tones of amber, honey, and cream with naturally occurring crystal and mineral textures. The spiral pattern is sharp and eye-catching, making it perfect for home décor, a collector’s cabinet, or as a unique gift for fossil lovers.

This is an extinct cephalopod mollusc belonging to the ammonites. It lived in the Upper Jurassic (172-149 million years ago), and its fossil remains are found on all continents.
These are marine animals, characterized by an external shell composed mainly of calcium carbonate, in the form of aragonite, and partly of an organic substance of a protein nature (conchiolin). The shell was internally divided by septa into several chambers, of which the mollusc occupied only the last (living chamber). The others, which made up the phragmocone (chambered part of the shell), were used as "air chambers" (similarly to the current Nautilus), filled with gas and chamber liquid to control the buoyancy of the organism. The pressure of the chamber fluids was controlled by a thin, richly vascularized, partly mineralized tubular organic structure (the siphon), which passed through all the septa and allowed the exchange of fluids from the blood and soft tissues of the animal to the chambers through a process of osmosis.
