Why is the fossil record incomplete? choose all that apply. -not all organisms are fossilized. -not all scientists believe in the fossil record. -not all fossils survive. -not all fossils are found.

Note that not all animals or plants or other living organisms turn into fossils when they die. Heck, you don’t even know if you will turn into fossil. In addition, fossils are very fragile and can be easily damaged by geologic activity, or by water and wind when exposed. Many fossils don’t survive long enough to be discovered, while other ones are located in inaccessible areas that they have no chance to be found. Therefore, fossil record is incomplete.
