How is the fossil record complete and accurate? why or why not

I would say that the fossil record is accurate. This is because scientists can confirm when the fossils were alive by the rock layer, and could date them by the rock layers. I would not say that it is complete though, because there are always more fossils that could be found in order to "fill in the cracks" of the record. :)
