Still quite shaky over finding this huge tooth! Just curious if it's possible to tell if this isn't an upper or lower tooth and would love any advice on preserving it or if that is something I should leave to someone more experienced in preservation. It is very fragile, missing some of the chewing surface and unfortunately a small piece broke off when my shovel hit it. It is roughly 13" long and has 13 plates.

I am afraid to handle it too much so the photos aren't great.

I found these two fossils on my latest trip, according to the sparse geological information I was able to find the sediment rock should be from Cretaceous, I presume both to be from some bivalve mollusks, but I came to ask if anyone is able to provide a more detailed id than just “bivalve” as I am very new to the hobby.

this plate was a piece of a large broken boulder on the dry shore of a fishing lake outside of Memphis, TN. i’m more of an agate guy, but I know something cool when I see it! I just don’t know more than the basics, so here I am! the whole piece is 9 inches long, and each shell is about 1.5 inches or less.

I’d like to know if these could be fossils, or if they’re some sort of calcite. Any ideas would be helpful, in case you’ve seen something like this before and there’s an explanation.

Thanks!

Hi there,

In the early 2000s, I dug up this tooth in Zeeland (the Netherlands). I would really appreciate more information about it. Is it indeed a shark tooth as I always thought?

Your help and tips are very welcome! 😄 Thanks in advance.

My son purchased at a rock shop at a cavern in Virginia. When it broke in half, I was looking at the cross section and wondered if it was real or not.

Is this a shell fossil? Standard bic pickle lighter for reference. Found in Missouri, near st louis.

I assume fish scales or something idk

Found on lake on lake Erie in Ontario.

Fairly certain its an Isotelus butt, just want your thoughts

Found on Vancouver Island

Megalodon ?

I can't tell if this is part of a trilobite or something else. TIA!

Russia. I don't know the exact location from where the pile of rocks in which I found the fossil was brought.

Not magnetic, crumbles easily.

I found this today in a creek bed in southeastern Washington. I thought it was petrified wood at first but after some research I think it’s a fossilized horse tooth! What do we think?

Found in central texas in a creek bottom. Curious about the two I was able to get a side profile of.

Found this in a creek near Seneca rocks with lots of fossil imprints in it. Has a piece of something sticking out. Is it worth breaking open?

my sister said she found this near the hudson river in new york, usa. if anyone can help ID and date that’d be cool thanks

It looks like the bottom of a bottle but I don’t know how rock would form in the shape of it like this as it’s ridged.

Found on a beach in Somerset UK
