MikeR's Fossil Gastropods


MikeR

Recommended Posts

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!

Mike,

A fossil hunting friend @jcbshark, gave me this find.  It it that same as lower left. If so, what does the tag say?

Nice! I have some gastropods from Sanibel, FL, do you know how old they might be? 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.

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

I have seen Mike's collection in person, and it is every bit as spectacular as the photos in this thread suggest.

@ClearLake Tamiami is mostly shell material with some sand. So specimens are loose. Easy pickins!!!!!

Hi,

 

These levels or formations seem very, very rich. Do you know how many species are listed ?

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.

It is estimated that there are between 1000-1200 species of mollusks above 5 mm found in the Tamiami.

It was great while it lasted.  The last of the Sarasota pits closed for good a few years back after almost century of operation.

Well rats, I guess I'll have to unpack my bags for that trip over to Florida!

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)?

Hi,

 

@ClearLake If you have fossil chitons, I’d love for you to post on them.

I wish I did, I would be happy to post them.  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.

My list is not updated, but I have around 600 different species of mollusks from the Tamiami.
