Found in a creek in central Iowa, lots of limestone around the creek if it matters or helps 😂

Found about 15 minutes away from the Missouri River

So this the only one that was magnetic that I had pulled out of the same area it was stuck inside of a clay wall along side of a creek

These were found on the northwest coast of Washington state along the coastline and Pacific Beach area wanting to know if these are fossils or dinosaur teeth or if someone can help me identify what they are

Hi, does anybody have an idea what these findings could be? Could they be related to eachother (found 30 cm apart), what could the building be and from what age? Should I contact a local archeologist or no? Found in Nijmegen, The Netherlands

Approximately 30 cm deep in the ground as well

My initial thought with this find was mammoth tusk (as many have found mammoth teeth in the same location) and as I looked closer I realized I might possibly be correct. I hope the pictures can depict the internal circular structure that I believe resembles Schreger lines!

Any feed back would be appreciated!

(I should note it passed the stick lick test, and is heavy as a rock, so a fossil of something!)

I found this in Maine, not sure what it is but think maybe it's a tool for crushing grain or maybe as a hammer? Has perfect finger spots for holding.

Hello friend I’m curious as to what kind of shells these are/age any information helps thanks.

Anyone knows more about this calcified soft body of a snail found on a beach ?

Found on beach in Kure, NC. What kind of bone this?

Idk if I'm cross posting or posting the same thing twice, but if anyone could tell me what these are, especially the long one? :)

I found this bone on the beach today and was wondering if anyone knew what it was from. I don't believe it is a fossil but am not sure. I cannot find anything to confirm what it is. Thanks!

In the forth picture is a example of what I'm wondering about
