化石拍卖

这是一个大型的手工精雕打磨的树脂、砂子和来自马哈加nga省的Phylloceras菊石的盘子。菊石在树脂层内结晶，之上的砂床之上。构图美丽。它已被玛瑙替换，内部的许多腔室内衬有方解石晶体。 
这是属于菊石的已灭绝头足类软体动物。它生活在上侏罗纪（约1.72亿至1.49亿年前），其化石在所有大洲均有发现。 
这些是海洋动物，其外壳主要由碳酸钙以文石形态构成，部分为有机蛋白质成分（角质）所组成。壳内部由隔层分成若干腔室，软体动物仅占据最后一个腔室（活腔）。其他腔室，即形成壳的腔室部分的“隔室腔”，则作为“气腔”（类似于现今的鹦鹉螺），充满气体和腔室液以调节生物的浮力。腔室液体的压力由一条细薄、丰富血管的、部分矿化的管状有机结构（虹吸管）来控制，虹吸管穿过所有隔，并通过渗透作用使血液与软组织中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.
