Het Patel Posted September 12, 2021 Share Posted September 12, 2021 Actually I cleaned the shell and removed inner matrix. I got this while digging at beach . 1 Link to comment Share on other sites More sharing options...
Mainefossils Posted September 12, 2021 Share Posted September 12, 2021 (edited) Nice shell! This does look like a conch. Unfortunately, it will be difficult to determine if it is a fossil without general geologic information or location on the find. Scale in millimeters would also help. Happy Hunting!

And here's the signs that it is not a conch. Look at the ridges spiraling around inside shell. Volute family. Conch/whelk/etc. don't have those ridges on the inside. Only Volute/mitra family have them. Maybe one more family that I forgot about. Link to comment Share on other sites More sharing options...

I see what you mean, but I think that some conchs also have spirals on the inner whorl. Below is a picture of a conch shell cross-section that I found on the web. A volute shell is still a possibility though, I do notice that the ridges are not as pronounced in the image below. I think we will have to wait for someone more experienced than me though, I have not collected conch or volute shells before. Maybe @MikeR could help?

Thomas.Dodson Posted September 12, 2021 Share Posted September 12, 2021 My immediate thought was a Volutid. Try looking into Caricella species to start. Geologic age and locality information might help. 1 Link to comment Share on other sites More sharing options...

MikeR Posted September 13, 2021 Share Posted September 13, 2021 The shell belongs to Turbinellidae, maybe Turbinella rapa. Also looks like a heavily worn recent shell. https://eol.org/pages/45372757/media?license_group=no_copyright Mike 2 "A problem solved is a problem caused"--Karl Pilkington "I was dead for millions of years before I was born and it never inconvenienced me a bit." -- Mark Twain Link to comment Share on other sites More sharing options...
