Florida Pliocene Shell and Coral trip


MikeR

Recommended Posts

This week, work carried me to South Florida once again and as the winter temperatures were a chilly 70oF, an opportunity to do some weekend collecting at one of my favorite quarries.  Unlike the famous shell pits in Sarasota where the Pinecrest Member of Tamiami exposes extensive beds of Pliocene shell, this quarry lying within the coral facies (Golden Gate Member) of the Tamiami is composed of not only shell but limestone, sand and corals.  I am constantly confounded with this locality's geology as certain faunal elements suggest Lower Pleistocene Caloosahatchee Formation.  Published reports however, state that the Caloosahatchee is not found this far south, but a more lengthy explanation will have to wait until the day I get around to updating my Pliocene Project blog entry.  Among the picture finds below is the best example of size, color and gloss of the rare shell Liochlamys bulbosa that I have ever seen.  Unfortunately, it was found by my collecting partner although my day was not a bust as among other finds, I found a very large complete Strombus and many Siphocypraea (not pictured).

Those are some big gastropod shells. Great finds!

Thanks,  Mike for sharing the adventure !!! :tiphat:

Not only the corals and shells, but I love the scenery. It must be the joy of finding at similar sites in my memory..

Nice corals.
Dichocoenia behind the great gasteropod ???.
Siderastrea over the screwdriver ???.
In the last photo there are many corals among bivalves and gastropods. Siderastrea again, Manicina, Stylophora, Antillophyllia ???.
It seems like an entertaining place for coral lovers. Most people saw gastropods and bivalves but there is always some crazy person who sees the coral. Mmmmmm .... nobody´s perfect.

The Golden Gate Member is known for it's amazing diversity of corals.

As Don mentions, the Golden Gate Member of the Tamiami is very rich in corals, representing a typical coral reef community including reef crest, reef platform, back reef and reef lagoon.  Over the years between both the Golden Gate and the Pinecrest Members I have accumulate a large number of different species of corals from some that are found in the Caribbean to others which are extinct.  From my fauna list as follows:

Good eye!  I missed that one.  It is hard to tell in the picture, but if I had to guess, maybe Stylophora granulata.

Oh yes, it is a very trained eye. Many hours looking at branchy coral poupourris. Stylophora, yes, that had seemed to me.
I will take the opportunity to ask your opinion about a sample that came to me many years ago in an exchange. It came to me as Antillophyllia but clearly it is not. I think it is Scolomya but I do not dominate your grounds to say much more about it. Location: Sarasota County, Florida. It is attached to a fragment of oyster shell and has numerous small holes.
Maybe you could complete the specimen file to me.

Wow! That looks like quite the place for Pliocene marine mollusks and coral and you must have had quite the time picking up those specimens. Thank you for sharing.

Definitely Scolomya.  I am thinking Scolomya lacera which has been reported from the Tamiami by Budd, Klaus, Meeder and others along with two undescribed species.  I have in my list Scolomya cubensis which they do not list so I will need to research that a little more to make sure it is correct.

Scolomya lacera was the species that I thought for that specimen but could not find citations in Florida.
Can you indicate the title and full reference of that publication to which you refer?
Some authors consider Scolomya cubensis and Scolomya wellsi as a subspecies of Scolomya lacera and refer to them as Scolomya lacera lacera forma cubensis and Scolomya lacera wellsi. Source Zlatarski and Martínez Estalella 1982 Les Scleractinaires de Cuba.

I have attached work from Jim Klaus specific to Tamiami corals as well as his supplemental which lists taxa to Meeder's localities.
