Howdy from North Central Florida

Howdy,

I need help in the identification of some very interesting coral fossils that were dug up about 17 years ago.

I work in the excavation business and started noticing some formations in the material that was being brought to me on a golf course we were building in Naples Florida.The material was from on site from a lake being excavated at about 25 feet in depth close to I 75.

When taken out of the ground it was a dull orange in color,like "Tang" in a glass.It soon turned to a skin color.some of these are agatetized coral I believe,others are not recognizable.

After 17 years I have seen nothing like them,,can YOU help me?? I have about a ton "really" of this stuff and would like to be educated on it if anybody knows the answer.

I think they are coral calcite?

Please and Thank You..

Dana Philmon..

Hello, and Welcome to the Forum. :)

I adjusted your pictures a bit for you.

These look more mineral/geological than biological in origin, ... to me.

I think we may need to see some higher resolution pictures, as these are rather fuzzy.

Nice minerals, it is a pity that the photos are so blurry. :)

I think calcite is a likely ID. Calcite has over 300 forms. The abundant shells in the subsoil would provide calcium carbonate in solution. Calcite crystals could form around coral or just about any durable focus in the subsoil.

I agree with Harry Pristis's ID.

One or two do really look like coral to me. I also agree with the statement that they look like karst calcite. Look up "travertine," that is what I suspect these are.

Some may be travertine,,but due to the bad clarity of the pics you cannot see very well the coral that is embedded in these..I am working on some better pics.

No travertines at all here, sorry. :unsure:

Post 15, the middle picture, the bottom piece does look a bit like coral. I think I can make out a hint of polyps in a few areas. The piece above it is also interesting looking although I have no idea what it is.

I think most of these may be coral covered in some mineral (perhaps clacite), but there's no doubt that there are at least a few nice pieces of coral amongst the pieces :)

I have some very large pieces of this engulfing coral,nearly all is coral just has a calcite covering the majority of the specimen.How long would it take the calcite to mineralize to this extent?

Calcite can grow quite fast...not sure though, it depends.
