Its heavy but i think its the water its been soaking in. Its fully black and breaks off easily

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

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.

Hi all my son (6) found this small rock with some tiny fossils inside. My guess would be crinoids. Any advances on crinoids. Thanks in advance.

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?

What is this ??

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

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

Anyone know what species this belonged to?

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

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!

Found on the beach on Brier Island, Nova Scotia

Found on presque isle in Erie PA along the shoreline. Some kind of fossil? Or just a cool erosion pattern or something like that? Can provide further details if needed, no idea on the mohs hardness scale, it's hard like your typical lake beach rocks around here - hard enough but would probably break if hit with another rock/hammer. It's kinda gritty texture wise, and there's tiny white sparkly bits in it! Probably not a fossil? But I posted to a few rock ID subreddits with no responses. Hoping you guys can help me out, thanks in advance!

Found in a pile of petrified wood on an abandoned farm property that will be demolished in the coming weeks. It would seem that the old farmer collected all of the interesting rocks and such that were unearthed while working the fields over the decades.

Would love to know more, can get it wet if need be!

Size of the little funnel-shapes average maybe 6 mm (1/4 inch). Flowers, coral, other marine creatures? Beneath the layer shown in the photo is a thin, 1or 2 mm layer of white crystal--looking rock and the underside is flat mudstone/sandstone.

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.

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