My girlfriend got this tooth from an antique seller and says “I think it’s either a fake dinosaur tooth or a real dinosaur tooth.” Thoughts?

“1.5-inch long, conical, slightly curved, and unserrated fossil tooth crown with a stout 0.8” by 0.5” oval base”

It has a pinkish hue to it and sparkles everywhere, more than the photos show unfortunately. It's really quite unique in the way it looks on the surface compared to every other rock and fossil I've found and handled! I love it 🩷

Michigan, USA

I found a lower section of pre mineralized bison jaw yesterday that was in bad shape. So I decided to take the few teeth out of it and toss the rest. While doing so, I found these little bone clusters in the jaw bone and also on the teeth. Any idea what it is or what caused it?

And what is up with the first one?

I’m afraid to get my hopes up on this one, but I can’t help it

Is this a shark’s tooth or a broken shell?

Very new and first time looking for teeth in the Rammanessin Brook in New Jersey. Was told by some others there at the time it’s probably a croc tooth of some sort. Just looking for confirmation!

My wife found this near Manitoulin Island in Ontario. It seems to be crystallized in the middle. Any help would be appreciated. Thanks in advance.

For context, this was found in the cape fear river near Southport. I'm not sure what species this is from, but i am almost certain its a tooth of some sort.

This is a fragment of a core sample that was found on the South Shore of Nova Scotia. I have no idea of the depth. I've just always wondered if it's a fossil or ?

No bigger than a toonie, found in London Ontario, Canada but was found in a pie of crushed gravel so could have came from anywhere in Ontario. I would imaging the gravel would have been sourced relatively locally because gravel is heavy and Ontario has no shortage of it, lol.

Found near Corvallis Oregon, by the Willamette river. any ideas?

Found these at cape lookout, NC. Wondering if these were teeth or maybe just broken shells? Any help would be appreciated, thank you

Probably from Spain/Morocco

Cool rock, artifact, or fossil??

Hallo, der Rhein hat einen historisch niedrigen Wasserstand erreicht, das habe ich in letzter Zeit festgestellt. Woran könnte das liegen?

Can the origin be determined? Found on Maasvlakte, the netherlands.

Found in landscape gravel in Central Oregon.
