化石拍卖（收藏家内饰）

这是一个大型、经过打磨的手工板，由树脂、砂子和来自马哈让加省的螺旋菊石（Phylloceras ammonites）组成。菊石玻璃内嵌在一层树脂中，之上是砂床。美丽的组合。它的表面已被玛瑙取代，内部腔室的许多部分衬有方解石晶体。 

这是属于菊石的已灭绝头足类软体动物。它生活在侏罗纪晚期（1.72–1.49亿年前），其化石在所有大洲均有发现。 

它们是海生动物，特征为外壳主要由碳酸钙以赭辉石（方解石）形态组成，部分为有机物质（蛋白质性质的 кончиолин）。壳内部分隔以壁层分成若干腔室，软体动物只占据最后一个（活腔室）。其他组成分形室（即壳的分腔部分）则像“空气腔”一样，被充气体和腔液以控制生物的浮力。腔室液体的压力由一条薄而富有血管、部分矿化的管状有机结构（虹吸管）控制，它穿过所有蜗间壁，通过渗透作用使血液和软组织的液体与腔室之间进行交换。

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.
