化石拍卖（收藏家内饰）

这是一个大型、打磨过的手工板，由树脂、砂以及来自马哈让加省的Phylloceras菊石组成。菊石晶化在树脂层内，位于一层砂床之上。构图美丽。它已被玛瑙替换，内部的许多腔室也镶嵌了方解石晶体。 

这是一个灭绝的头足类软体动物，属于菊石。它生活在上侏罗纪（大约1.72亿至1.49亿年前），化石在所有大洲均有发现。 

这些是海洋动物，外壳主要由碳酸钙组成，呈文石型，并部分含有一种有机物质（Conchiolin，角质质）。壳体内部被隔板分成若干腔室，软体动物只占据最后一个腔室（活腔）。其余腔室，即充作“气腔”的部分（壳的膨腔部分），用于调控浮力，充满气体和腔室液。腔室液的压力由一条薄而血管丰富、部分矿化的管状有机结构（虹吸管）控制，该结构穿过所有隔板，并通过渗透过程使动物的血液与软组织的液体在腔室之间进行交换。

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.
