Suppose you found a fossil of a clam shell what can you conclude about the once-living organism and how it became a fossil?

Question

I need some ideas for answering this question.

Answer 1

I can conclude that the once-living organism used to live in water, because of the fact that the fossil is a clam-shell. It became a fossil after it had died. Over time, the clam-shell would get buried in sediment, and eventually become a fossil.
