I grew up in Florida; most of what you are finding are more recent. If you want to find the old stuff, do what I used to do: drive a bit further north into southern Alabama and Georgia and try some trails in parks near areas that used to be wetter in the past. Some of the trails run along old creeks, rivers, and shoreline remnants. I have jars of shark and ray teeth as well as various snail shells, corals, and some bone fragments that are in the 10-15 million year old range. However, get inside some of the karst formations and you can find things embedded in the limestone. If you like early echinoderms you'll be set.

Wow that’s awesome! I don’t think I ever found shark teeth on the beaches in Florida.

@@lissi6931 You'll find lots of dogfish shark teeth. Maybe even a dogfish washed up on shore. They are small but very common on the Atlantic and Gulf coasts. Try St. George Island or the western end of Pensacola Beach where the fort is. There are wide areas of beach that get tidal pools and lots of tiny neat things get washed up. It'll be hands and knees time but it can be worth it.

Now you know why we're so miserable!

I'm glad you enjoyed!

Of course not all of these areas are tropical but you get the idea.

I need to visit!

@@BenGThomas it's a tiny town that my family currently lives in xD if you do travel there, let me know and I'll find out the beaches that haven't been overly fished out by the tourists :3

Recent teeth will be white or even translucent just like your teeth.

They will shortly they are very recently exposed to the elements

Megalodon was not that old

Megaladon isn't existed yet at that time
