ynot Posted October 8, 2018 Share Posted October 8, 2018 Really not sure about this one, thinking some type of clam(?). 1 Darwin said: " Man sprang from monkeys."

KimTexan Posted October 8, 2018 Share Posted October 8, 2018 I’m thinking it is a type of oyster, but the 2nd pic seems a bit off for an oyster. That said I have seen some weird oysters. 1 Link to comment Share on other sites More sharing options...
BayFinds Posted October 8, 2018 Author Share Posted October 8, 2018 The outer cone is a smoother texture and then there is a stonier texture filling it and coming out the wider end. Could it be some sort of tube worm? Link to comment Share on other sites More sharing options...
ynot Posted October 8, 2018 Share Posted October 8, 2018 The smother area is where the shell is or was (dependent on how You look at it), the grainy gray is the mud that filled the shell (when it was buried). 1 Darwin said: " Man sprang from monkeys."

It may be too worn to get much beyond it is shell. There were some weird snails out there too. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

KimTexan Posted October 8, 2018 Share Posted October 8, 2018 The filling may be shale. Shale can be broken down with 5% vinegar, but you’d want to make sure the shell wasn’t reacting. The narrow open end is a bit odd looking for an oyster. It could be a tube worm case Link to comment Share on other sites More sharing options...
Kane Posted October 8, 2018 Share Posted October 8, 2018 The shale would have to be significantly calcareous to react to vinegar. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

NSR shale/clay breaks down nicely in vinegar. Sometimes it is halfway between a shale and very hard clay. Link to comment Share on other sites More sharing options...

This has to be the most helpful and fastest responding forum ever! I’ve learned a lot from this little fossil, and I’m excited to share the info with my two boys. . . and get them to research the type of clam that left it!
