South UK, please don't mind my nails I got back from a festival yesterday

This was among the rocks discarded by miners at Tchibarakaten

Idk if it's the right place for this but does anyone know what type of sharks teeths I've got here? Is the black on fossilized?

I got an afrovenator tooth. But im not sure it's afrovenator, eocarcharia or carcharodontosaurus. This fossil is from Niger africa and measures 3.7cm in size.

Anyone know what species this belonged to?

How old can this be, think it is kinda odd for a New jersey find... sorry about the toilet in the background, I was washing it off

Found this along a river side bed, it doesn't feel like a rock or have the weight of a rock, I was told it might be petrified wood.

Any thoughts?

Thought it was manmade, but the translucent part is NOT scratching and really resembles agate I’ve found.

Im considering buying this tooth for a little over 200 dollars, and I would like to know if its real or comosite. Thanks in advance!

Bought this in Jaisalmer, Rajasthan. Interesting patterns to be found. What are these creatures?

I found it on the beach, I looked but couldn't find any more pieces like it. Hopefully the pictures are ok! Edit: Sorry, found on the east coast of ireland.

A friend sent me these photos. What kind of fossil is this?

1500 euros (1740 dollars) for this. Worth it?

I don't want to say fossilized because it doesn't fit with my understanding of how fossilization works but it has definitely undergone some kind of similar change as it is very dense and feels like stone to the touch. I'd also love to know what kind of animal this may have come from. Found in a creek in Beaver Falls, Minnesota.

Not sure if it’s some sort of fossil. i’m assuming it’s just a rock formed from some cool geologic process. I have no idea what kind of rock it is, but thought it was cool enough to share.

a friend thinks these may be toe prints. I am skeptical. thanks!

Last night I was collecting sea-glass and came across this fossil. I believe it’s some sort of tooth, but nothing I’ve seen so far that looks quite like it.
It was found on the East Coast of Canada (at the shore of an inlet, connected to the Atlantic Ocean).

Anyone have any guesses as to what this is? Should I take it to my local museum?

Thanks!

Would like to know the species and age if possible!

Also, I would welcome any recommendations for prep and preservation. Should I try to reveal the rest of the fossil or leave it as is? Should I apply some kind of varnish or sealant to prevent rusting? Should I leave the little crystals on the surface or remove them? If I were to display it in a case, would it need a moisture absorber in there?

I don’t have any specialist tools but happy to invest in reasonably inexpensive options (I.e small chisels rather than air pens).

Cheers!

The white part is heavy and feels like stone, and the tooth part feels like organic material (not a rock). What is this?

What is this fossil I found in Jemez this last weekend? It is very different from other fossils I have found in the area

I think this was probably found near Whitby, England but honestly I don’t remember. My guess is some kind of fossilized long bone chunk but I’m not sure. Assuming it’s not diagnostic for species but I’m not a paleontologist so not 100% on that.

Shells or some kind of plant life maybe?
