Need to lighten and reduce contrast on your images. There are any number of free apps or computer programs that can do that.

Blurry photo, might be jasper, not a fossil

Bull Shark, Carcharhinus leucas

Sorry but I don’t see anything but a rock here.

Appears to be an interesting colored rock, but I don’t see a fossil here.

Probably a worn dolphin tooth. The root would be the curved end.

I don’t see a fossil here

I don’t see a fossil here, just an oddly shaped rock

Sea Urchin

These are modern bones and not fossils

By the Miocene which so you seem to be mostly posting from, brachiopods were probably about as rare as they are today. They are found but much more likely would be mollusks with some gastropods thrown in. Nautiloids usually reside in deep water. I have seen them found in an Eocene deposit but they certainly weren’t common, I saw maybe 2 or 3…[Read more]

I haven’t seen the likes of this before. I wish the root was less worn. The typical cat shark (Scyliorhinus) has thick roots and this doesn’t. I think it is something off the wall and rare like Parmaturus or Psuedotriakis or something like that. I don’t know what it is.

Again I think it might be phosphate. The good news is that where there is phosphate nodules or blocks, it is a good locale to look for fossils.

Looks like a piece of phosphate which are often nodule like or rounded

Looks good, marked as research grade

Top is probably an intermediate Odontaspis reticulata, Next is a lateral or posterior (depending on size) Carcharias cuspidata. Bottom is harder to tell. Need to see the other side. The lateral cusplets are puzzling. Also a scale on the images would be helpful.

Looks like an ironstone concretion. Where ironstone deposited around an object or sand.

Looks like chert, a mineral.

Galeocerdo casei if it is actually from Belgrade.
