Hi everyone,

I found this in January of 2017 on Shark tooth island on the Savannah River in Georgia.  Always have been curious what it is.  The area has dredged material and contains fossils from the Miocene, Pliocene, and Pleistocene.  It is slightly conical and symmetrical, uniform, and ovalish in cross section - straight in profile with no discernible curvature.  In profile, one side is smoother and striated, the other coarser, dimpled, with elevated black speckles.  It is not porous inside like other bones from the area.  It appears to have schreger lines.  I'm not sure if it is some sort of tusk, but I havn't seen other tusks without some degree of curvature.  

Overcast day here in Seattle.  If photos aren't clear enough I'll upload some others on a sunny day.

Thanks!
