Relatively few lifeforms end up fossilizing and then some of those fossils later get eroded. The percentage that make it to the present is low.

    I'm no paleontologist but it seems like our total knowledge of certain eras comes from a few river banks collapsing on whatever lived there. That's not going to be a great representation of all life at that time.
