CEMEX Brooksville Quarry trip and ID


Sacha

Recommended Posts

I had the good fortune to visit the CEMEX Brooksville mine with the Tampa Bay Fossil Club last week, where I wanted to look specifically for examples of Phymotaxis mansfieldi. I had dolomitic casts from the Santa Fe river, but that was it. I was fortunate enough to find a nice one this trip along with a very tiny one and a partial. This post, however, is looking for the ID for the rather large "clammy" bivalve which was fairly common in the Suwannee Limestone in this mine. Anyone familiar with this guy? Appreciate the time!

Nice finds!!  Especially the Phymotaxis. Are the others all  Eupatagus  antillarum?

No Mike. In the Suwannee limestone the super common echinoid is Rhyncholampas gouldii

The bivalve is a Lucinid or more specifically belongs to the family Lucinidae.  LINK

Thanks Mike. I recognize the photos aren't very good, but Roger Portell concurs and add that they could be Miltha or Lucina. Would better pictures help to get to species? I could try tomorrow with some better light.
