was hiking in bowl of fire and saw this. thought it was a lithic at first, then thought maybe a tooth ? or is it just a very serrated flake of rock ?

Those are best from flints and obsidian material, though when scarce, other rocks are used. The object's serrations lie in the harder layer, which show signs of knapping, so I reckon it's a human artefact, especially as the serrations are on one side, therefore, used as a cutting, slicing tool.
