Bronzviking Posted June 3, 2018 Share Posted June 3, 2018 I found this shell cast on Honeymoon Island, Florida, USA. As you can see from the photos it's a complete shell cast and measures about 4 x 3 1/2 inches. I did some research and found similar pictures that looked like Turritella Shell. Would the Forum agree with this ID?? If so I read that this is an extinct species of fossil sea snail. Is this correct? I appreciate your feedback. Thank you!

Auspex Posted June 3, 2018 Share Posted June 3, 2018 It certainly looks like a steinkern of a high-spired gastropod, I do not know whether it is of the Genus Turritella, though.

Tidgy's Dad Posted June 3, 2018 Share Posted June 3, 2018 Gastropod, yes, Turritella, no, though not sure what it is, the proportions and size seem wrong for Turritella. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
MikeR Posted June 4, 2018 Share Posted June 4, 2018 Height versus width too small to be Turritella. Maybe Cerithiidae or Potamididae.

Bronzviking Posted June 4, 2018 Author Share Posted June 4, 2018 I found this photo on the net. Turritella in Matrix #504 Goodland Formation. Looks very similar to mine accept it has 4 spirals and mine has 3. Could it be a partial shell cast of a Turritella?? Link to comment Share on other sites More sharing options...
Plantguy Posted June 5, 2018 Share Posted June 5, 2018 Has some similarity in general shape but I'm not sure its labeled correctly and its from a different age and formation. You'd be better off looking for Mio-Pliocene, Pleistocene types from Florida on the web but I'm not sure without a complete one showing its ornamentation/various views you are gonna be able to do much more with narrowing the ID. Mike knows his stuff. Turritellas are very tall/thinner relative to their width and yours doesnt exhibit those characters. Here are a couple Mike has in one of the families he was proposing to give you a better look... http://www.thefossilforum.com/index.php?/search/&q=cerithidea&sortby=newest Just in case you werent aware here's a couple of other links that are very helpful. https://www.floridamuseum.ufl.edu/invertpaleo/gallery.asp?gallery=Florida Mollusca-Gastropoda http://www.marinespecies.org/photogallery.php?album=702 There are hundreds of different fossil gastropod species here in Florida. You are in good hunting grounds! Regards, Chris 2 Link to comment Share on other sites More sharing options...
Bronzviking Posted June 6, 2018 Author Share Posted June 6, 2018 I'm more knowledgeable of rocks than fossils but I find them fascinating! Thanks for every bodies comments and useful links! I thought this was a cool find. Would you say this is a rare find? Could it be some family of worm or snail? 1 Link to comment Share on other sites More sharing options...

It is a nice find. It is not rare, but rather common. It is a snail (gastropod). 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Tidgy's Dad Posted June 6, 2018 Share Posted June 6, 2018 Yes, it's nice enough, but not unusual. I'd still have picked it up and kept it. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
dalmayshun Posted June 7, 2018 Share Posted June 7, 2018 All over Florida we use Stone called rip-rap,. Chunks of limestone mostly, coquina sometimes, but most of it has shell, or coral imprints of some kind. I live on a little lake and decided to have my bank terraced couple years ago. We used rip-rap as the retaining walls... Most road culverts have retaining banks made of the stuff. Now, when I can't get out to field hunt, i go to my terraced bank, sit down with my loop and turn over the rocks to look at coral, bivalve and gastopod impressions... Yours is similar to many, and common, but no less fun to contemplate. Enjoy it. Link to comment Share on other sites More sharing options...
Plantguy Posted June 7, 2018 Share Posted June 7, 2018 Yep, agreed it is cool, a gastropod/snail and you will find more. Have fun! Regards, Chris Link to comment Share on other sites More sharing options...
fifbrindacier Posted June 7, 2018 Share Posted June 7, 2018 I have several steinkerns of gastropods that look like yours, and here is one of my Turritelae (each square is half a centimeter) : "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux." (Antoine de Saint-Exupéry) "We only well see with the heart, the essential is invisible for the eyes." In memory of Doren Link to comment Share on other sites More sharing options...
