The Carboniferous Lewellyn Formation runs through northern and central Pennsylvania and is the source of much of the coal in "Coal County." Along with the fossil fuel are much better preserved examples of ferns, horsetails, and confer relatives, as well as some rare insects. In addition to anthracite coal, it is composed of sandstone, siltstone and mudstone.
The Pinecrest Sand Member of the Tamiami Formation is a series of beds which contain an incredible diversity of marine life from the Upper Pliocene ranging from approximately 4.5 to 2.5 million years ago. Primary among the organisms that draw attention to these deposits are the gastropods which are so well preserved that they appear to have just recently washed upon the shore. Although both professional and amateurs have collected from the Sarasota quarries which have mined the mollusk shells for construction for over 50 years, a single monograph has never beeen produced. In addition, I am also picturing gastropods from the Tamiami coral reef facies, the Golden Gate Member which contains some of the same species as the Pinecrest but also many endemics. Although short on description which is essential in peer reviewed scientific publications, I hope this gallery will serve as a guide to those who have trouble in acquiring the few out of date works that have delt with the Pinecrest.
I don't have all that many teeth like a lot of collectors here in this Forum, but I have found, purchased or traded for a few fishy things along the way.
Update New Year's 2019: The collection has been growing thanks to trades, purchases and my own field finds.
My main interest is fossil fish, but you will also find some other vertebrates like amphibians, mammals, reptiles and birds here in this album:
Fossils from Solnhofen, Messel, Holzmaden, Liaoning, Bergisch Gladbach, Green River, Linton, Mazon Creek, Monte Bolca, Fiume Marecchia.....and other places around the world.
The overwhelming majority of this Ammonite fauna is preserved as limestone molds. But they can nevertheless make very pretty pets. There is a seemingly unendless amount of sites which can be visited since a great expanse of these layers is exposed from the north of Switzerland over the Swabian Alb up into the Franconian Alb in Bavaria. The forms and variations of this fauna are also manifold and the species and genera are being continually moved about or renamed, so I can't guarantee that my IDs are up-to-date.
The Quarantine of 2020 made for frustrated fossil fiends all over the world. The Aurora (North Carolina, USA) Fossil Museum came up with a wonderful way to stay afloat and keep people's sanity at the same time: Fossil Hunter's Emergency Survival Kits. Each kit contained two gallon-sized plastic bags of micro matrix from the adjacent Nutrien (Formerly known as Lee Creek) Phosphate Mine. The mine strata are a mixture of Early Miocene, Pliocene and Pleistocene layers, which are sifted together extensively before fossil hunters can get a look. The fossils from my kit, as of the time I began this album, are all Pliocene/Pleistocene. They must have ben scooping out the upper layers that day.
My main interest is fossil fish, but here in this album, you will only find invertebrates:
Fossils from Solnhofen, Messel, Holzmaden, Liaoning, Bundenbach, Green River, Linton, Mazon Creek, Monte Bolca, Fiume Marecchia...
Brachiopodes are sometimes not at all easy to identify down to the species, particularly the orders of the Rhynchonellida and Terebratulida which have innumerable variations and species in Jurassic times, for instance. So it could be that I'm not always right, which is why there are a lot of question marks.
