Florida Gastropod Identification Help - 2 Different Fossils

[Gregory Kruse]

Hello everyone,

 

I found these gastropods along the Sanibel Causeway in Ft. Myers, FL.  They were in a pile of shells being used for landscaping so I presume that the sediments came from a nearby quarry of ?Pleistocene age, possibly the Caloosahatchee Fm.  Can someone help me verify and identify this fossil?    Thank you!

@MikeR Hi Mike, Can you take a look at these and let me know what you think they are?  Thanks!

The first two are Melongena subcoronata and the third is Cerithium.  Without the aperture it is hard to say which one.
