化石拍卖（收藏家内饰）

这是一块大型、切割抛光的手工板，由树脂、砂子以及马哈让加省产的 Phylloceras 菊石组成。菊石在树脂层中结晶，位于一层砂层之上。美丽的构图。它已经被玛瑙替换，内部许多腔室内壁镶嵌着方解石晶体。 

这是一个已灭绝的头足类软体动物，属于菊石。它生活在上侏罗纪（大约1.72亿到1.49亿年前），化石遗存遍布各大洲。 

它们是海生动物，外壳主要由碳酸钙组成，呈文石形态，并含有部分由蛋白质性质的有机物（壳质蛋白，conchiolin）构成。壳内部由隔膜分成若干腔室，软体动物仅占用最后一个腔室（活腔）。其他腔室构成的炮层（壳的分室部分）被用作“空气腔”——类似现代 Nautilus——充满气体和腔液，用以控制生物的浮力。腔室液体的压强由一种薄而血管丰富、部分矿化的管状有机结构（虹吸）调节，它穿过所有隔膜，使动物的血液和软组织中的液体通过渗透作用与腔室互通。

This is a large, cut and polished hand made plate made of resin, sand, and Phylloceras ammonites from Mahajanga Province. The ammonites are crystallized within a layer of resin and above a bed of sand. A beautiful composition. It has been agate replaced, and many of the internal chambers are lined with calcite crystals. 
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.
