Fragment Mammal or Shark Tooth Bone Fossil- Need ID

[Bronzviking]

I was shark tooth hunting and found this fragment on Casey Key, Florida 9 years ago. I recently went through my stuff and found 3 pieces of Mastodon Tooth Enamel. So I'm not sure if it's too small to ID but has a interesting wood grain pattern with enamel on the top. Can you ID it? Thanks FF!

First impression is a rock but I suppose it does share some characteristics of a very worn bone fragment.

Doesn't look like it is large enough (or distinctively shaped) to be able to assign a probably ID to this one. Does indeed have the right texture for bone but I'm not sure if the shiny layer on one side is actually enamel or something else. I can't quite make out how this would be an enameled surface or an occlusal (chewing) surface of anything I am familiar with. Might possibly be the result of an extra hardened end of a long bone (but merely a guess). Though a fossil, this one may remain an unknown. Out west where dinosaur fossils are possible (none in Florida) this would be fittingly called a "chunk-o-saurus" but here it's merely a chunk-o-something.

 

Cheers.

I took the liberty of brightening and cropping your pictures. 

 

Not really a bone guy, (take with a grain of salt) but it looks more like rock to me.

Yeah thought it would be too small and worn. Thanks for looking! Can you ID this tooth I just bought at a show?

Looks like a lamine camelid cheek tooth.

Thanks Harry! What about my fragment on top of page? Can you tell if it is a partial tooth? @Harry Pristis

Item #1, I am seeing bone and it looks a lot like the mineralization that the bone gets in the "White Sands Deposit" I have dug in here, LOTS of silica replacement.

Sorry, Bronzviking, the first item is nothing I recognize.

Thanks for verifying (#1) was bone. I was pretty sure but hard to tell in photos. Where is the "White Sands Deposit" and what do you find there? @caldigger

Monterey County, California.

 It is a western segment if the Temblor Formation that encompasses about a 120 mile stretch of the San Joaquin Valley in central California.

Same animals as Sharktooth Hill, but different depositional environment and preservation.
