I and the state have been under water a lot, but I'll have to admit that the state has me beat!
40 Fathom Grotto (240 ft) near Ocala, Fl... I was diving with the infamous Hal Watts becoming a "Grotto Guide". We approached the wall at about 130/140' when I notice that someone has stuck little round knives all over the wall. I was rather upset that they would be so mean until I got to about 110ft and most of thr narcosis wore off. The knives were actually sand dollars stacked one on top of each other and embedded in the wall. This goes all the way to the surface. Whoa! Later he showed me 9 sea biscuits in a row, like they were playing "follow the leader". I think I grasped the concept of a "billion" that day.
Paradise Springs just outside of Belleview Fl. At 18 ft you can see the bottom of an immense sand dollar in the ceiling... it measures 18". At @ 30 ft you can find part of the vertebrae of a marine iguana in the wall (rt side going down). They claim there is a whale bone in the fissure leading down to the cavern, but I have serious doubts about that.
Wekiwa River, just downstream of the marina (just outside of Altmonte Springs). We excavated %75 (I think) of a Mastadon skeleton from the river. Both tusks were there, though the left one was missing the very tip. This guy was HUGE. A professor from FSU orchestrated the whole thing.
Phosphate Pits, just south of Bartow Fl, I recovered 2 Megladon teeth, both over 5 inches
Spring just outside of Ocala, I found a 1.5" Meg tooth that I wear around my neck.
Just from diving, I have found 1,000s of shark teeth, a whale vertebrae, ray plates, a femure from a sloth, a tooth from an extinct horse, Gator teeth, fossillized coral, cochina rok, Crocodile teeth, part of a skull from an extinct rodent (which is now at the UF) as well as many other pieces and parts that have yet to be identified. BTW, my wife says if I make a mention of her here, she will surely smite me.
Yeah, we got fossils!
