美丽抛光的菊石化石片 – 天然螺旋几何形状 -
这片惊艳的菊石化石片展现了大自然设计的永恒之美。经切割与抛光，揭示其复杂的内部腔室，色调温暖，介于琥珀、蜂蜜与奶油之间，伴随自有的晶体与矿物质纹理。螺旋图案轮廓清晰，极具视觉冲击，适合用于家居装饰、收藏柜，或作为送给化石爱好者的独特礼物。

这是属于菊石的已灭绝头足纲软体动物。它生存于上侏罗纪（约1.72亿—1.49亿年前），其化石在全球各大洲皆有发现。
它们是海洋生物，外壳主要由方解石型的角闪石（文石）组成，部分由有机质的蛋白质物质（珊瑚质）构成。外壳内部分隔为多腔的室（由隔板分隔），软体动物仅占据最后一个活腔。其他腔室构成的

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.
