Are fossils rocks?

Question

I have to write a report on the Petoskey stone. It's fossilized coral, so does it count as a rock?

Answer 1

Yes.

Fossils are impressions of what once was there. There is very little if anything left from the original animal or in this case coral. The coral's calcium carbonate CaCO3 has been incorporated into the limestone. So a fossil is actually made up of limestone, shale, etc. whatever native rock is there.

In some plant fossils, black carbon impressions are often the only thing left of the original plant leaf, but the fossil is still the native rock you found it in.

Answer 2

Yes, very insightfull though becuse as Coral is a living organism I can see how the question came to be. Change is the only constant , dead tissue becomes mineral so is classified as Rock,Pebbles or Sand. Minerals is all inclusive of this. Oil or Petrolium is a Fossilized Fuel so Oil and this is known as a mineral. You can say that the coral is a rock, but I would use the mineral becuse of the Living Organism that coral is or was.

Answer 3

Fossils are the remains or the traces of past life. Remains include fossil shells (including coral), fossil bones, fossil teeth, fossil eggs, coal (which is fossilized leaves, stems, and sometimes pollen (cannel coal)). Traces are such things as footprints, molds, casts, borings (some animals bore into the shell of others in order to eat what is inside). Fossils are not normally considered rocks, but they could be (coal definitely is a rock). To be humorous (hopefully!) if someone threw a fossil clamshell and it hit you you would DEFINITELY call it a rock.

Answer 4

I lived in Petosky Michigan. Yea, they are rocks. the ancient coral gets submerged in rock and as it's calcium slowly dissolves, harder rock replaces it over bagizillions of years so it still looks like coral. I have several of them. Just Google Petosky stone!

Answer 5

fossils are rock formations formed by adhering to a hard organic substance

Answer 6

fossiles are imprints left in rocks

Answer 7

Not all.

I'm a fossil, and I'm not a rock.

Answer 8

Geologically, Yes. I would also look into carbon dating.

Answer 9

yes

Answer 10

No!
