The fossil record is an account of known entities that have been found by scientist and historians that attempts to reconstruct the history of creatures and events that happened on Earth. The fossil record has massive gaps that haven't been able to be filled; however, there still are lots that have been discovered. The fossil record will be incomplete for quite a long time.
This is because the earth was created 4.6 billion years ago and humans have found fossils from around 1+ billon years ago. There is also no way that the fossil record is complete because some if not most fossils have been berried way to deep for humans to get to.
