ClearLake Posted May 11, 2020 Share Posted May 11, 2020 Again, I will say, very nice collection. And I like the organization. I'm curious, as I have never collected out of the Tamiami Formation, what is it like that you can get those delicate specimens such as Vermicularia (and others) out? Is is a very friable sandstone? Must have been quite low energy to preserve those with that detail (yes, I know it is fairly young, but still...). Do you collect them out of blocks of undisturbed matrix? Just curious, thanks!

While I kept a few from the beach, I also kept some older looking ones from my aunt's backyard. Many of the smaller roads on the island are paved with shells. I live on Sanibel , and occasionally hunt fossil shells. I am not as good as Mike on dating things, but show what you have found.

FossilDAWG Posted May 11, 2020 Share Posted May 11, 2020 Let's leave this thread for Mike to show his collection. If you have specimens you need help with, start a thread in the Fossil ID forum and you'll get lots of help, including I am sure from Mike who is always generous with his time and expertise Don 4 Link to comment Share on other sites More sharing options...

Mike Indeed it is. The Tamiami is mined for construction fill and it is said that much of I-75 south of Tampa is underlain by fossils from the Sarasota pits which were almost pure shell. Further south there is a lot more limestone in the Tamiami. Collecting in the Tamiami is a lot different than that in the Jackson Bluff, Duplin and Yorktown Formations which are also featured with the drawers. Most of those exposures are on rivers and creeks although collecting in the single pit that I know of which mined the Moore House Member of the Yorktown Formation in Chuckatuck, Virginia was similar to that in Sarasota.

Now thats what I call diversity!! That would be great, what percentage of those do you estimate you have in your collection? It looks like you have a great representation. Any chitons in there (I know, a different Class of Mollusca, but a personal favorite)? Link to comment Share on other sites More sharing options...

It is more of a research interest of mine than a collecting interest (as I have yet to come across them where I have collected). Not that common in the fossil record, especially the Paleozoic where I primarily collect. That's why I was curious if they are found in a younger formation with such wide diversity like this.

The Florida Museum of Natural History has quite a few entries for chitons however I would say they are rare as I have yet to find or at least identify any plates in all of my years collecting Florida shell beds. Chiton plates are not uncommon in the California Plio-Pleistocene as I have found quite a few. Some of the showier examples below. The composite which I purchased last year was created by the late Frank Peska Jr., a long time collector of the California Pleistocene. 3 "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...
