Why have we NOT found examples in the fossil record of every animal that ever lived on Earth? select all that apply

-To become a fossil, an animal must be quickly and completely buried in ash or sediment before it has a chance to decompose.

-Many fossils remain buried. We can only find them when they are exposed by erosion or excavation.

-To become a fossil, an animal must remain buried for thousands or millions of years until it (and the layer around it) turns to rock.

-It is just a matter of time before we find them all. Rocks contain the history of all life, if you know where to look.
