Nimravis Posted May 6, 2019 Share Posted May 6, 2019 While in Florida I have been doing some fossil shell collecting, I really do love collecting these shells, the diversity is great. I do like finding large and small shells, but the smallest are always my favorite as the quality is usually exceptional. In this post I will show a few pics after I found some of the “regular” size shells and then my haphazard attempt at trying to identify some. Please do not take my ID’s as truth- though I love collecting these shells, I am really bad at getting the ID’s correct. There are a lot of shells that I do not have any ID for and I did not attempt to guess like I did on the others. Some of the specimens that I took pictures of are not the greatest and I have since found better ones, but since I already took the pics, I did not update. I did not take any individual pictures of the smallest pieces, but believe me, some are really small. My favorite find so far- the colors are phenomenal and the glossiness is just crazy- because of this, I thought is might have been a Lindoliva spengleri, but I do not think it is large enough. I believe it is Oliva sayana, and again it is my favorite find. Here are a couple other pics after I picked some up. Now i will start with my attempt to ID some of my finds- this will take a few posts since there are a lot of different ones. 2 Link to comment Share on other sites More sharing options...

FranzBernhard Posted May 6, 2019 Share Posted May 6, 2019 @Nimravis, many thanks for sharing these beautiful shells with us! Some points : - Its amazing, how similar they are to the miocene Paratethys mollusc fauna here in ol´ central Europe. But species, even most genera, are different, though. - Your small ones are the lager ones in my area... . - My favorte is clearly Nr. 69. - Would you like to provide a little bit of background? Which formation, how did you collect them (natural outcrop, quarry, beach, river...). - @Max-fossils, don´t miss these... . Many thanks again!

Nimravis Posted May 6, 2019 Author Share Posted May 6, 2019 I went out for a 3 mile walk on Sanibel Island to watch the sunrise this morning and I decided to check along a road that has fossil shells. Last year or the year before, about 1 block away, I found a rare shell and I was lucky enough to find another one today. First a pic of the sunrise- This the second time that I have found this type of shell below and I never found the two that are after it- all found this morning. 3 Link to comment Share on other sites More sharing options...

Which formation, how did you collect them (natural outcrop, quarry, beach, river...). One of the fossil shell experts would have better info, but I believe all of these shells are Pliocene-Pleistocene from the Caloosahatchee Formation. I collected these from “fill” used by some hotels for walkways, and a construction site farther North that I had permission to collect in and along the Sanibel Causeway. Years ago I was able to get into a quarry near Arcadia, but that is no longer possible. That quarry was outstanding for fossils, I just wished then that I spent more time collecting the smaller shells 1 cm and under. Again, I did not post many of those unless it was the only size I had. 1 Link to comment Share on other sites More sharing options...

digit Posted May 6, 2019 Share Posted May 6, 2019 You really got a terrific diversity of gastropods and bivalves (and a few corals). @MikeR could speak more authoritatively on the identifications you've made above. If you want to make changes to the names on the numbered photos above but the time limit for editing has run out (which it will in time), PM me with replacement images labeled correctly and I can substitute the updated images for you. I generically call the shelly formations in Florida either the Caloosahatchee (which is probably overly specific) or how they appear on the geological maps TQsu (Tertiary-Quaternary shelly units). Again, Mike could likely speak to in-place formations. For the shelly fill used as road bedding here in Florida, you would have to have an idea of the source quarry to be more certain. This may be of some help to you in terms of understanding Florida's geology: https://mrdata.usgs.gov/geology/state/fips-unit.php?state=FL Hope you wrap everything well for the trip back home.

Tidgy's Dad Posted May 6, 2019 Share Posted May 6, 2019 How marvelous! What an incredible amount of species and such a range in size. Some of those are huge. And the detail is extraordinary. I also like 69 the best. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

I try to understand the american geological words. Coco Ken is right and also a formation can consist of several 'Members'; smaller units within the formation. Life's Good! Tortoise Friend.

FossilDAWG Posted May 7, 2019 Share Posted May 7, 2019 Amazing assortment of shells! Are you sure these are from the Caloosahatchee? They seem to have a Tamiami Formation/Pinecrest Beds aspect, and the SMR quarries were pretty close by and could have been a source. I guess the question could be decided by IDing some formation-specific species. As always when it comes to Pliocene/Pleistocene shells, @MikeR would be the one to look to for an authoritative opinion. Don 1 Link to comment Share on other sites More sharing options...
