化石拍賣（室內收藏家）

这是一个由树脂、砂和马哈琼省磷莹螺（Phylloceras ammonites）化石制成的大型、打磨后的手工板。琥珀状的菊石被嵌入一层树脂之中，位于一层砂砾之上。整体构图美丽。它已被玛瑙替换，内部许多腔室被方解石晶体衬里。

这是属于菊石的已灭绝头足动物。它生活在上侏罗纪时期（约1.72亿至1.49亿年前），其化石在所有大洲均有发现。

这些是海生动物，外壳主要由碳酸钙以文石型形成，部分由一种有机蛋白质性质的物质（角质蛋白conchiolin）构成。壳体内部被分隔为数个腔室，动物只占据最后一个腔室（活腔室）。其他腔室，即充作楔状的壳体的一部分的腔室，被用作“气室”（类似于现今的鹦鹉螺），充满气体和腔液以调节生物的浮力。腔室液的压力通过一条薄而高度血管化、部分矿化的管状有机结构（虹吸管）控制，它贯穿所有隔板，使血液和动物软组织与腔室之间通过渗透作用实现液体交换。

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.
