Got this stuff at the beach today. Does anyone know what the top third from the right is and the last 2 on the top right are?

Many are too worn to identify. The second pic looks like iron stone concretions but I'm not sure

The tooth third from right is sand tiger lower...the other two are new to me...they look to be possible fish scales ..from something with thick plating.
Here are Alligator gar for comparison .


The color polish and type of the shark teeth look like the St. Augustine area to me...just guessing.

I was at Guana Reserve Beach. Heres a couple more pictures of those things.

That's just up the road a piece from a place I go quite often.
I'm still stumped on those.

These two pointy things appear to be ossicals. If there is no enamel on the points, they may be osteoderms from a tortoise. If there is enamel, they may be dermal denticles from a ray. My best guess is that they are ray denticles.
