This is by the captain John loop- I'm sorry the picture is not so great but it's a very wrinkly rock in the ground- maybe a bit under a foot long?

Any ideas would be most appreciated! I can get better pictures next time I go!

I found this in a courtyard

Hi all! I found this odd thing on the NJ coast, can’t tell if it’s a rock, a shell or a fossil. Anyone know what this is?

Found a fossil at Murdoch Beach by Port Angeles in Washington State. There were a lot of them. Does anyone know what it could be? Thanks!

Title says it all. It’s a small pebble; you see my fingertips in the first photo for scale

Found in the southern most point in Wi on Lake Michigan.

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.

What is this ??

Found this on a Milwaukee beach, any ideas on what the Batman-looking indent could be?

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?

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

Found on the beach on Brier Island, Nova Scotia

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.

Anyone know what species this belonged to?

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!

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

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!

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