One contributing factor might be the fossilization process itself, because preservation issues can create biases in the fossil record.

一个促成因素可能是化石化过程本身，因为保存问题会在化石记录中造成偏差。

Once a bone has been chewed on, trampled, transported, broken apart, abraded and finally buried, fossilization can occur.

It takes special conditions for fossilization to happen, and, for whatever reason, the places that coelacanths like just don't preserve fossils very well.

化石化的发生需要特殊的条件，而且无论出于何种原因， 腔棘鱼喜欢的地方都不能很好地保存化石。

There's a variety of fossilization processes and the most common is permineralization, where crystals grow into the pore spaces within the hard parts of an animal.

化石化过程有很多种，最常见的是全矿化，即晶体生长到动物坚硬部位的孔隙中。

So fossil fossilization is the process of an animal or plant becoming preserved in a hard petrified form, and only a tiny fraction of all the animals are preserved as fossils.

因此，化石化石是动物或植物以坚硬石化的形式保存的过程，所有动物中只有一小部分被保存为化石。

The process of fossilization, or the process of making fossils, has preserved information about animals and plants that lived a very long, long time ago, although you can't eat these animals and plants because they're really, really, really hard.
