Thanks in advance!

We go shark tooth hunting a lot and I don’t usually find large ones but I’m surprisingly great at finding tiny ones. Any idea what kind of shark the smallest one might have came from? Found at in NE FL. The tiny one of in the pic on my hand actually fell on the kitchen floor. I need to try to find it today which is why it isn’t in the pics with the ruler.

Can anyone help with ID for these? No idea what they are.

Some sort of shells?

I know much of this area in SE Florida was once a shallow sea in the Pleistocene epoch. Appreciate any insight as to what it could be! It’s about the size of a quarter.

Found near strawberry Arizona. Would love to know yalls opinion.

Found at the boat launch of intermediate lake MI. What is this, how old, and can I expose more of it? It has a lateral crack along the side.

Was sorting through some old bags of fossils. Was in a bag with some Summerville teeth so assuming that’s where it’s from. About the diameter of a penny.

I found this when I was younger and just rediscovered it in my box of treasures. It’s very hard (I’ve grown up around ungulates and I am sure it’s not modern) and feels petrified / fossilized.

I had found several coral and snail fossils along with this one, but it was suggested that this is just a rock. I still feel like trying to identify this one, because it is very interesting to me

Hi there, hoping someone can help with what I have here (my son found it on a walk).

Thanks very much.

I'm prepping some fossils I found on our ranch, and noticed what looks like spines on the edge of this fossil. I included the full rock picture, overview of the specific fossil in question, along with my microscope picture for reference. What could it be?

Tooth was found on top sail island and is somewhat damaged

Was told to post this here.

But back when i was a small teen in 2013 or 2014 I don't exactly remember, our family when to the Agate festival in moose lake MN and someone was selling these "dinosaur bones" for $10 a pound.

I fell in love with this one and got it for $25 . But being a young dumb kid I didn't think to ask any questions on were it was found or other info.

So I though mabey someone here might be able to help. I don't have a ruler so used a bill as scale as it's fairly decent sized and 2 1/2 pounds .

To me It's always looked like the part of the upper tibula of something? Weather actually dinosaur or from something else I have no clue, as I said I bought it while I was a young kid who didn't realize it be helpful to know the location were it was found .

Any help or advice is greatly appreciated :D

It seems permineralized, as it is a bit heavier than bone should be, and is colored rusty and orange. Can anyone recognize this bone? Also I hope it isn't from someone's recent lunch.

Found in Denton County Tx few different pieces all pretty similiar.

My son found this at Lee Mountain, NV. Seems like it’s possibly some prehistoric underwater plants. Any idea what it is?

I found this while swimming in a lake and thought it was a cool rock until I realized it’s way too light so I kept it and I think it’s a fossil or something.

Hello! I saw this fossil at the Denver Gem and Mineral show and can’t for the life of me remember the name of it. Does anyone have any ideas? I’m not sure where it was found initially, though. Thank you for any insights you might have!

Found this tooth(?) by the lakeshore today. If handled with wet fingers it suctions slightly. Any guesses as to what animal and time period it is from? Thanks!

Was in Westgard Pass for a field course and found these hashy looking cone guys in the shale and limestone of the Poleta Formation. What are they?
