Waterlines going in neighborhood, contractor lost a day dealing with these, some mineral stone. These two they wrenched out with excavator, next day they switched over to jackhammering a path approximately 40’ long to lay the pipe into making big rock into little rocks. They inquired if we want them for landscaping, wife had me hose them off discovering this more fossil like appearance. Any idea what mineral these could be?

I would say some kind of lava but being that you are in Florida, could it be coral?

Florida? Then perhaps calcium from coral (basically limestone, right?). Homestead AFB, originally a SAC heavy bomber base, was built on the stuff.

At first look, I was going to say it was a type of lava. Then I heard you are in Florida. See below:
I believe it's an old lava flow. Pumice, I think.

Its Coquina. Not really coral anymore and considered a rock down here. It used to be mined and used for construction until the ‘70s, when they realized it was our foundation and restricted.

Yep, another name for a specific type of limestone. Cheers
Yes.

Coquina (/koʊˈkiːnə/) is a sedimentary rockthat is composed either wholly or almost entirely of the transported, abraded, and mechanically sorted fragments of mollusks, trilobites, brachiopods, or other invertebrates.[1][2] The term coquina comes from the Spanish word for "cockle" and "shellfish".[3][4]

For a sediment to be considered to be a coquina, the particles composing it should average 2 mm (0.079 in) or greater in size. Coquina can vary in hardness from poorly to moderately cemented. Incompletely consolidated and poorly cemented coquinas are considered grainstones in the Dunham classification system for carbonate sedimentary rocks.[5] A well-cemented coquina is classified as a biosparite(fossiliferous limestone) according to the Folk classification of sedimentary rocks.[6]

Reminds me of caliche in Nevada. I was at Nellis...oh, circa 1977 or so....and a guy in the squadron asked for some help digging small trenches in the yard of his newly built house in order to put in an in-ground sprinkler system. He promised beer and BBQ and since me and some other guys were staying in the BOQ (which sucked), we raised our hands. Anything to get off base and have a bit of fun.

But, we weren't from NV and had zero idea of caliche. Yeah, we worked our asses off with picks and shovels but finally we all quit and told him to rent a jack hammer! haha

This was a training TDY prior to an overseas PCS so I don't know if he ever got his trenches dug.

Cheers
 
Guess this belongs here. My dumbass made the news. In typical news fashion, the only thing correct in the article is type of stone and weight.
