Not always, especially in paleontology. Any kind of preservation counts, e.g. amber: https://en.wikipedia.org/wiki/Fossil https://en.wikipedia.org/wiki/Fossil
- dredmorbius 5y agoStrictly speaking, "fossil" means "dug up". That meaning's become confounded with the sense of "fossilised" as in "mineralised", but the original etymology referred to anything dug from the ground, hence coal as a fossil (that is, dug-from-the-Earth) fuel, a nomenclature later passed on to petroleum and natural gas. https://www.etymonline.com/word/fossil https://www.etymonline.com/word/fossil (I'd only discovered this myself recently.)
- dredmorbius 5y agoOh, and "mineral" is ... stuff that comes from mines. (Etymology is fun.)
- krisoft 5y agoOh you are right. I totally forgot about amber. Thank you.
