I alway envisioned Florida as ancient seabed, ground up shells, and sand. I know there is a lot of farming in central fla, but I never thought of it for fossil beds.
You learn something new every day.
FWIW, the pic of the Mammoths and snow covered peaks obviously is not Florida, even as it existed during the last ice age, which, geologically, wasn't long ago at all, ending about 10-12,000 years ago.
You have to remember that the ocean was about 400 feet lower at the end/peak of the last ice age. That means there would have been a ridge of hills around 400 feet high and hundreds of miles long visible from the ocean shoreline. I don’t understand why people/scientists would not have been interested in mammoth bones that still had skin on it.
