Possible croc tooth?

Not crocodilian . . . the enamel has spalled off this tooth rather than delaminate as is common in crocodilian teeth.  I'm not sure what tooth this is.

Not a claw.  The keratin exterior of a claw doesn't preserve as a fossil.  The claw core is just bone.  Your find appears to be enamel.

I agree with Harry that this is tooth, not gator or croc, not claw. Where did you find this?  Florida -- river find?

There is a big clue in your 3rd photo: it has a large empty cavity where the root should be..  this is normal to gator, croc, whale...but it is not any of those. Harry, do other teeth have cavities like this?

 

I had this tooth identified by a number of experts as a non erupted canine from a dire wolf. SO I guess it could be Jaguar or Bear

Mammal teeth pass through a stage where they are hollow enamel shells, with enamel and dentin being laid down on the interior of the shell.  Roots develop in the same outside-in manner.  This in-filling continues until the tooth has only a narrow pulp-cavity remaining.  In other words, look for the largest cavity in the permanent teeth of the youngest individuals.
