This looks too clean to be real, especially considering all the frog fossils I see are of bones only. If this isn't a natural formation, how in the heck was this done? Cause it looks like real rock at the very least to me, and the negative impression itself does look natural(the edges of the frog features look weathered), apart from the incredible detail. Sorry if this is obviously fake, I don't think I've ever looked at more than a couple fossils in my entire life :/
I found this gastropod imprint a couple weeks ago in Tertiary sediment (geologic maps) I found this gastropod online (Falsifusus ludovicianus) which lived during the same time period and has similar ridges and those tiny crown marking near the top. Let me know if this seems reasonable (I put the pictures of the gastropod I found online in the comments below.)
smokeyjoe posted a topic in Fossil IDThis "river rock" came from a bag purchased at a home center in Illinois so the place it was originally found is unknowable. Can someone help me identify this, please? It is a cylindrical impression of something with rings. In my mind's eye I'm seeing a plant stem or reed of some sort buried in mud near a stream or pond, but I'm virtually clueless about these things and would appreciate it is a more knowledgeable kind soul would offer a more informed opinion! Is it plant? Animal? Insect? Approximate age? Thank you!
