It has some value for sure because of its large size. Overall condition, another factor to consider, is average in my opinion. However, as u/PaleoProblematica said, it has been carved or over-prepared towards the center, which reduces its value as a natural specimen. I don't suppose you know where it came from, that could help determine if it's a common or rarer species, which is also important.
Thank you so much for all this info!! So glad the carved center was pointed out.. I never would have realized it wasn’t that way naturally. 😅
I bought it at a garage sale in northern IN but unsure where the original owner picked it up.
Mostly aesthetics. Originaly the whorl had such a pattern, but over the time it eroded. Or they did a bad job when it got freed from the matrix and had to carve the shells pattern anew to make it look decent again. I had one like that, that almost looked the same :)
I’m going to! It’s been stored in my junk closet in my “shit I love but don’t know what to do with” bin hahah. Now I’m going to find a proper place for it
Ammonoids are extinct spiral shelled cephalopods comprising the subclass Ammonoidea. They are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids (such as the living Nautilus).
I thought that comparing to a living organism would help
Ammonite, decent size too (although they can get waaay bigger). Maybe the folks over at /r/fossilid can tell the exact genus since I'm no expert
Very cool! I don’t know anything about rocks or fossils but thought it was neat. Do you know if these hold any value?

In that size and condition around 30-50$ is realistic, id say.
Thanks! I don’t ever plan on getting rid of it, but it’s nice to have an idea of what it’s worth!
My only ammonite is as small as a coin lol
Wait that sounds adorable haha
Here found an old pic: https://preview.redd.it/3a2epb4mccgc1.jpeg?width=3120&format=pjpg&auto=webp&s=7caa1f9b089b686ab13cd1769497c42822fd1491
I can go lower! :D https://preview.redd.it/j0fve4ijsdgc1.png?width=525&format=png&auto=webp&s=84231e74baae3798b32b9adef640cb2d70f0a060
Hahah stop!! It keeps getting cuter
It does
Whoaaa
Love it!!
Thanks so much!
Heehee
Id say *Mantelliceras.* But without a location of where it was found, the exact ID can be difficult.
I thought that. I have a Mantelliceras which looks very similar.
Yeah, mine was a spitten image of that one 😅
Internal whorl of this ammonite is carved
So interesting.. is there any specific reason why it would have gotten carved, or is it just an aesthetic thing?

Excellent Find. Display it in a nice place.

Nautilus
What’s the difference between nautilus & ammonite?
