RocksAndFossilsHunter Posted August 22 Share Posted August 22 I found this ammonite in the Mississippi River in Minnesota, I was wondering what type of genus of ammonite it is? Link to comment Share on other sites More sharing options...
Bullsnake Posted August 22 Share Posted August 22 I think that is a gastropod (snail) internal mold. Neat find! Maybe @minnbuckeye will have more info to add. 3 Steve Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 22 Share Posted August 22 Agree with Gastropod. No sutures = not an ammonite. Possibly Maclurites sp. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

minnbuckeye Posted August 22 Share Posted August 22 Views from all sides, top and bottom too may help to ID this GASTROPOD. It is very water worn which lessens the chance of success Link to comment Share on other sites More sharing options...
minnbuckeye Posted August 22 Share Posted August 22 Maclurites is a possibility but I lean towards Holopea. 1 Link to comment Share on other sites More sharing options...

I was just leaning towards ammonite because I didn’t know any snails could resemble the shell pattern of a snail. Link to comment Share on other sites More sharing options...
joaoarguello3 Posted August 27 Share Posted August 27 It's not an ammonite. It looks like a Maclurites according to the images. Link to comment Share on other sites More sharing options...
