D选项是不是做同位语呢？又因为同位语不像定语状语那样要求就近修饰，所以它就没有紧挨着fossils。
可是老师我记得你说过同位语从句的先行词是要是抽象名词的啊 Σ( ° △ °|||)
是同位语，但不是同位语从句。
同位语从句是：the fact that A do B。这里的that A do B叫同位语从句。
同位语是用一个名词来同位于另一个名词，甚至一个句子。例如
Trump, the president of USA, is a man.
这里的the president of USA就是Trump的同位语。同位语本身不要求抽象名词什么的。这道题目就相当于是一个这样的同位语，只不过名词身后还带了一个自己的定语从句罢了。
明白啦谢谢老师！
这里的同位语+定从是说明了这是些什么样的化石。和同位语从句不一样的！
