The planet Earth is about 4,600 million years old.
Fossil evidence becomes abundant in the geological record in the Cambrian Era, which was about 550 million years ago (when hard shelled animals appeared)
Therefore (550/4600)*100 = roughly 12% of Geological time contains abundant fossil evidence.
However, please note that (non abundant) fossil evidence goes back about 3600 million years, (3600/4600)*100 = roughly 73% of Geologic time.
