最后一句怎么和全段的逻辑不一样?不是化石少吗,怎么化石床还研究了好几年?高手解惑~
One interpretation regarding the absence of fossils during this important 100-million-year period is that early animals were soft bodied and simply did not fossilize. Fossilization of soft-bodied animals is less likely than fossilization of hard-bodied animals, but it does occur. Conditions that promote fossilization of soft-bodied animals include very rapid covering by sediments that create an environment that discourages decomposition. In fact, fossil beds containing soft-bodied animals have been known for many years.

答案和解析
其实就是最后转折了一下,并不是最后和全段的逻辑不一样,前面说软体化石不容易形成只是为了凸显成型的软体化石床的珍贵.有点儿类似于说“虽然这个东西很难找,我还是帮你找来了”
另外就是倒数第二句阐述了促进软体化石形成的条件,也就是说虽然软体化石本来不容易形成,但正是因为有这样促进形成的条件,达成了以后,才有大家闻名已久的软体化石床,不是转接的很好吗?=) 而且少和研究多少年不冲突的,好多东西越是稀少才越值得研究
