To which ungulate species does this tooth remainder belong?
Its definitely not a marine mammal, just based on size and general configuration.
those convoluted ever growing teeth are pretty diagnostic of non-cetacean ungulates.
Just based on the pattern I would say bovidae, but that does not narrow it down much in turkey, the H shaped central portion is fairly diagnostic of bovidae. However you have several antelope species not to mention domesticated animals that each would fit that category.
I suggest changing the title to ask for ungulate tooth identification. You need someone specialized in mammalian teeth to narrow it down to species. if you can add more shots of the tooth crown (the complex ends like those below) that is the part most useful for identification. See the examples below. The more you have the better.
