This is a lot of all extinct Florida fossil shells:

The names are listed in order from left to right. When there is a duplicate, it is not listed again.

Arca wagneriana (there are three of these in this lot, the smallest is whole - both halves - which is rare, it is possible two of these could be Arca imbricata which still exists, but they are a little challenging to distinguish)

Crassispira perspirata

Conus spuroides

Fusinus caloosaensis

Apicula apicalis

Hanetia mengeana

Pyrazus scalatus (with near full aperture - rare)

Andara rustica

Naticarius plicatella

Hystrivasum locklinii (possibly horridum)

Turbinella regina (juvenile)

Turbinella scolymoides (juvenile, possibly hoerlei)

Strombus leiydi (juvenile)

Mitra lineolata (one has a complete aperture - uncommon)

Conus adversarius (the only cone known to be sinistral - the aperture opens on the left when the apex is held up and the aperture faces the observer)

Cymatosyrinx lunata

Fasciolaria scalarina

Buscyon rapum

Cerithium dalli (With near full aperture - rare)

The names of these can be quite variable if looked up, I have tried to find the best info. Also, at times there are multiple similar species with only minor differences that have been scientifically described in the Florida fossil record. I'm not convinced these aren't variable forms of the same species, as even with modern shells there can be variations in shape and color. Food for thought!

The locality of these specific shells is not precisely known, but these will likely be from the Caloosahatchee formation which spans the boundary of these pliocene and pleistocene ages (1.8 to 2.5 million years ago)

This was a period before the last ice age, and Florida was mostly shallow ocean as the water level was so high (hence these deposits are found far inland today). The land and sea then had many species we would feel were familiar, but most of which are now extinct. In the sea this included sea cows (dugongs), various seals and sea lions, whales, many corals and fishes, and many sharks (sadly megalodon was gone by this period). On the land there would have been Mammoths and Mastodons, Giand sloths and Giant armadillos, Glyptodonts, and Saber toothed cats as well as dire wolves. The period of the Caloosahatchee formation was a time well before humans came to Florida, and indeed according to the fossil record, before humans existed. No Human would have walked the shoreline and picked up the extinct species here.
