I collect from Belgrade, exclusively from the grey and tan River Bend Formation at the base of the quarry. I have numerous shark and ray teeth. In addition, the grey matrix rock on Topsail Beach is also River Bend, Oligocene, and I have a lot of material from there as well – though mostly invertebrate, there are some shark and ray teeth, fish scales and verts. and misc. bone bits in matrix from there as well. Also 2 primitive cetacean brain casts and 2 isolated teeth in matrix were recovered and are now at the Smithsonian.
