@vperez, it appears to be a broken lower third molar of Metaxytherium, an extinct genus of dugong. Image 3756 is the crown view whereas image 3737 looks like the anterior or mesial view with a nice facet showing where it wore against the lower second molar.
Cool find! Makes me jealous, because I used to live along Rattlesnake Creek in Gainesville. All I ever found were shark teeth, which are interesting in their own right, but not as interesting as a dugong (note my bias as a mammalian paleontologist).
