It turns out the answer depends on who you ask.
Technically, if you’re a paleontologist, any remains or traces of an organism preserved in the ground are counted as fossils.
But most laypeople (and paleontologists!) will not use the term for something less than 10,000 years old. If its younger than the agricultural revolution, you probably wouldn’t call it a fossil.
Then there’s the question of petrification. Sort of like Harry Potter, it means when something turns into stone. Most people, when they imagine fossils, imagine something that the eons of time have slowly turned into stone. Looking back at the paleontology definition, petrification isn’t included. But for something to have been preserved for more than 1 million years, it probably got turned into stone. How else would it have survived? So many fossils are petrified, but its not a requirement.
