This specimen was found in micro matrix purchased from the Aurora, North Carolina Fossil Museum.
Teeth are very similar to the genus Galeocerdo
with finely serrated, long, thick and warped crowns; pronounced notch, small serrations on heel of distal side. Undulating margin
and fine serrations on mesial edge. U-shaped root with a prominent protuberance on lingual face and transverse groove (Fig. 5.10).
Physogaleus contortus differs from the genus Galeocerdo in
having very prominent and bulging root with the deep notch, and a much more erect crown in lateral view. (Leder, 2005)
