古玩柜拍卖（我的第一个古玩柜）

这是一个大型、打磨光亮的手工树脂、沙子和来自马哈让加省的Phylloceras菊石的拼花盘。菊石在树脂层内结晶并位于一层沙床之上。美丽的组合。它已被玛瑙替代，且许多内部腔室内壁镶有方解石晶体。
这是一种已灭绝的头足类软体动物，属于菊石纲。它生活在侏罗纪晚期（约1.72亿至1.49亿年前），化石在几乎所有大洲都可发现。
这些是海生动物，外壳主要由碳酸钙组成，呈文石型（aragonite），部分由一种有机蛋白质物质（conchiolin）组成。壳的内部被薄壁分隔成若干腔室，软体动物仅占据最后一个腔（活腔）。其他腔室构成的分室腔（壳的分腔部分）被用作“气室”，充满气体与腔液以调控生物的浮力。腔液的压力由一条细小、血管丰富、部分矿化的管状有机结构（虹吸管）来调控，虹吸管穿过所有薄壁，使动物的血液与软组织中的体液通过渗透作用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.
