Help identifying these pieces

[JTab0125]

Need help identifying these fossils. They were found on beach in North Florida. Only 2 in my collection I cant seem to figure out. Help is appreciated!

 

The 1st one is oval shaped and has to 2 close holes in the center of one side. flipped over the holes are on the outside of the circle. it is small so its hard to see in photo.

 

The 2nd one I have found quite a few of these. (the one in my hand) They get from this size to about as large as a dime. The have a long pointed ridge down the center of it, and the underside kind of bowls inward.

Move to FOSSIL ID.

It's hard to say anything about these without better closeups. Even then an id would be difficult here in my opinion. I couldn't even say if they're a fossil or a rock. Your best bet, unless someone who knows better chimes in here, would be to take them to your nearest natural science museum for evaluation.

Looks like a plate piece? But could also be a nice pebble!

The one in my hand, i have found 10+ of these and really think they are some type of bone. This ones pretty small but ive owned pieces that were double this size.

 

I keeping thinking its some type of scute. Similar to an alligator how it has that ridge. Maybe some type of small reptile or even a tail scute?

If you are able to take brighter, close-up pictures, that will help with an identification. Scute will have a texture that I am unable to see in these photos. Thanks.

Possible tilly bone maybe?

Fin Lover is correct . . . We need much better images to identify these finds as osteoderms.  I assume that, if they are truly osteoderms, they must be sloth bones.

Attached are a few more I found over the weekend. They always have the same features. They are predominantly oval shaped with a tall ridge down the center and the bottom kind of 'bowls' inward.

 

The smaller ones tend to be a bit more circular overall than the larger one tend to be a stronger oval shape.

 

I know this is definitely fossilized bone, and i have found now 15+ of these on the beaches of North Florida. So Im thinking Pleostene Epoch. Its the only fossil ive ever had i simply cant find out what it is haha.  Any help would be AWEOSOME! thanks everybody!

They looked very vaguely like searobin rostrums that we find but not enough similarity for one of these.

I think they might possibly be Tilly Bones (hyperostotic fish bones):
