manganese dendrites, not a fossil

looks like manganese dendrites

Any detail on the other side? Looks like either a shell or ammonite with some of the nacre intact. Leaning ammonite because of the colors.

A lot of members live in Florida USA where shark teeth are pretty common. There are many locations around the world that have them, but they may not be where you live. See if there is a rocks and fossils guide for where you live, it Google your location and fossil to see what comes up. More involved is macrostrat.org but it does somewhat give a…[Read more]

white stuff on the Meg are barnacles. for the rest @bill-heim is your guy

Agree horn coral

Nice job on the new photos! I still don’t think it’s fossil wood. I’m a little unsure it is a fossil, but it certainly looks like it was alive at one point.

it’s interesting but does not look like wood that I’m familiar with. The photos are really out of focus, so it will be harder to identify. It looks like the fossils in your area are marine.

You’ve gotten a dozen opinions, it’s still not a fossil. Sorry.

Not everywhere in the world has fossils. Some places have books that will list where to look for rocks and fossils, but you need to know the laws where you are and if you can collect anything. There is no easy trick to making fossils appear, you have to go to areas they might be found and spend a lot of time looking at the ground. Rock vs fossil…[Read more]

Most likely natural. Something happened to weather out and our brain fills in the pattern. Not that people don’t enhance things like this, but they happen naturally all the time. It’s still a great rock though!

Second from right is ray plate. For the rest tagging in @bill-heim

I think it’s a tabulate coral.

Looks like magnesium dendrites but I can’t get it to zoom clearly enough to be certain.

@leonardo-miranda haha thanks for clarifying. I do think they are fossil stromatolites, but there are mineral formations that are sometimes similar too. That’s what I meant by if they aren’t fossils.

without looking up the age/formation I’m inclined to say stromatolite. Really neat pieces, even if they aren’t fossil

belemnite. Somebody else might be able to be more specific

Can’t tell if this is other side of previous or new piece, bit looks like it could be wood

Looks pretty wood-y to me.
