SMR Shell.. years to Identify

[Shellseeker]

Back in May 2013, I had my 1st field trip into SMR aggregates quarry, east of Sarasota. I opened this thread for identification and sharing.

The 1st photo was this one. 

 

Note the bluish tinge on some of these fossils...

 

Fast forward 9 years. On the 4th of July , our 1st granddaughter , Ella came for a visit and I moved 80% of my collection out of my fossil display room to get a 3rd bedroom for Ella. The fossils including the ones in this photo, went under the house in the carport. In Sept 2022, an 11 foot storm surge from Hurricane Ian scattered my fossil collection hither and yon. 

Fast forward to the day before Thanksgiving  last week.  I was putting together some shells from the carport as a gift for a friend. Reached down into a box and took the top ziploc bag and it contained most of the fossil in the above photo. 

I had never identified the Turritella in upper right... but realized because of the blue tint,  it came from SMR.. 

So I was able to find the photo,  and the Formation,  and get a closeup photo to share this morning.

Hey Jack, very nice, mighty awesome refind! I dont think I had any complete specimens of those but I remember seeing pieces of a large Turritella from APAC and in the area around SMR and APAC.

 

FYI, I also saw this recently published article (last year) so it may have had its genus changed if thats what it is as they've learned more things about these guys and recategorized some...now Caviturritella??....would need Mike or one of the other bivalve experts to verify...
