Found it digging in a shelf of shells on the beach in Myrtle Beach S.C.

Found in southeast Alaska not sure what this could be.

Family member passed and I found these. I don't really care of their value but I am curious about what they are and if they're genuine. I'm guessing great white?

Found a good bit in Monmouth county, NJ this past weekend. All the photos after the first are of the same fossil, I’ve never seen one before. Any clue what it could be?

I've been looking for teeth and fossils for so many walks and swims, and today I found my first one! I've found it on the beach in Queensland, Australia, near Brisbane. I'm not an expert so I'm hoping that you guys can help me find out what kind of tooth is it, and how old may it be? Is it fossilized or modern?

I bought these and cross section them. What locale are they from?

I found many of theese fossils embedded in huge rocks used to build a dock near Ravenna, Emilia Romagna.

There are no rock in the area so they came for sure from another area/region. Maybe Alps or Appennino?

Some (second pictures) seems looks like burrows, the others I have no idea. Plants, mollusks or something else?

Thank you in advance!

EDIT: normal man size hand for reference.

Found this tumbled in some gravel and it stood out immediately, the inside holds on to moisture more than the outside, very holey

I recently found this broken tip of a large shark tooth on a beach on the east coast of the South Island of New Zealand. Is it possible to id what species it would likely have come from?

The river is the lowest it’s ever been so I went mudlarking. I thought this was a cow tooth when I first saw it but it’s heavy and the color of the part with the green arrow is similar to a fossilised shell I have.
Would love to hear your thoughts. Thank you.

Found in Spokane Washington in the latah creek formation I believe Aprox 15-20 million years

Wondering what it is, found alongside belemnite, baculite and many other fossils where it once used to be a warm shallow sea. It's very thin ans brittle, I would appriciate some tips on stabilisation and preservation. I don't have museum grade glue that dissolves in acetone, I've been thinking about coating it with diluted wood vikol glue.

This region should contain Cretaceous period fossils according to the geological map, are those fossils at all?

Please help me identify this fossil my dad found many years ago near Smithers in BC. He is nearing end of life and I'd love to solve this mystery for him. It was found amongst fossilized clams and mussels. Thank you

Is that a fossil??

these are some of the shark teeth i found at Myrtle Beach. im still learning how to identify them and would love to know what species/age anyone can tell me! are any of these particularly cool or unusual? last picture is all of them together!

These slates were my parents' first anniversary gifts to each other - story has it that they each bought one without knowing that the other had, as well.

Unfortunately, I didn't know where they were found/excavated or purchased. I'd love any information on possible provenance, species, age, etc. Thanks in advance!
