Sentences with phrase «fossilization process»
The phrase "fossilization process" refers to how living things, like plants or animals, gradually turn into fossils over a very long period of time. Through a series of natural processes, such as being buried in sediment and having their hard parts replaced by minerals, their remains are preserved and transformed into fossils that can be discovered by scientists millions of years later.
