Help with these please, from Venice

[I.C. Fossils]

Hi, we found the longer one (on left) in February and the other two a few weeks ago in Venice. I haven’t found these before and cant find comparables. We dont go to the west coast often so hoping someone might be able to clarify what these are. Im thinking the small square-ish one (on right) may be a small part of a tooth but definitely not sure.  The scale bar is 1cmx1cm. Thanks

The item in the middle appears to be a dermal denticle from a stingray or shark, I don't have many and don't know much about them, so hopefully someone else can confirm. The item to the right however is half of a pufferfish mouth plate.

Here's some pictures as examples.

Agreed with both those two IDs. The striated item on the left is likely a very worn horse tooth.

 

 

Cheers.

Thanks SawTooth and digit for the fast replies! Cool, I guess we have a dermal denticle and a horse tooth in the collection now.. and it didnt even cross my mind that the other one was another mouth plate since it had such a nice surf polish and some minerals to it, man wish it was complete. Thanks again!

Don't worry, your sure to find another mouthplate if you look regularly, when I go to the beach I normally get at least 1 per trip.
