来自马达加斯加的极好保存的化石木片。时期：下侏罗纪。颜色美丽，木质纹理清晰且保存良好，质量确实出色。 
注意在数百万年里木材裂缝中形成的美丽矿物晶化现象
这是来自马达加斯加安比洛布（Ambilobe）的广口 petrified wood（菩提树状的树木 petrified wood，Araucaria）的一个圆形大块。 Araucaria 是针叶树科中的一员，包含现代的猴赛雷树。这个约2.2亿年的 petrified wood 已被切成两面抛光，因而内部木质细节和美丽的着色一目了然。 
 petrified wood 指通过矿物化作用将木材变成石头（化石化）的过程。在此过程中，所有有机物质被矿物质替代，同时保留了原有结构的很大一部分，例如树轮。要实现这一点，木材需要埋藏在氧气含量低的环境中，以防止分解，且有流动、富含矿物质的水，以便矿物质替代结构。着色由在化石化过程中水中存在的各种矿物质/杂质所致。例如，许多红色可归因于铁化合物，绿色则来自铜，等等

A really well preserved fossil wood slice from Madagascar. Period Lower Jurassic. Beautiful colors, evident and beautifully preserved wood texture, truly excellent quality. 
Note the beautiful mineral crystallization created over millions of years inside the cracks of the wood
This is a wide round of petrified wood (Araucaria) from Ambilobe, Madagascar. Araucaria is a coniferous tree in the family that includes the modern Monkey Puzzle tree. This 220 million year old petrified wood has been sliced and polished on both sides, allowing the stunning inner wood detail and beautiful coloration to easily be seen.
Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. In this process, all of the organic matter becomes replaced by minerals, while much of the original structure, such as tree rings, is retained. For this to happen, the wood needs to be buried in an environment low in oxygen to prevent decomposition and with flowing, mineral-laden water, so minerals may replace structures. The coloration is caused by various minerals/impurities present in the water during fossilization. For example, red colors in many cases can be attributed to iron compounds, greens due to copper, and so on
