Very Large Pilocene Sand Tone Mineralized Fossilized Welk Shell

Description

Fantastic large Fossilized extinct Florida “Sinistrofulgur Contrarium” Welk family shell. Possibly from the Late Pilocene Era.
The age range is estimated to be from 11,000 years to 2.5 million years old!! Amazing!
Fossil is well preserved and measures about 6” by 5”.
For identification I use the Neogene Atlas of Ancient Life on line and I contacted the University of Florida Museum of Natural History’s Invertebrate Paleontology Collections Department and they identified most of my collection as P5 era fossils from the Pinecrest Beds of the Tamiami Formation which is in the Sarasota, Florida area.
I was informed the different colorization patterns come from what kind of minerals the pieces were in the ground water where they fossilized.
Each shell will be wrapped individually and shipped with care.
Combined Shipping Available.
