I started the day at the Calvert Cliffs, but after not finding much besides two small damaged Megs, I headed to the Potomac River, in hopes of finding the perfect Otodus tooth.  The tooth I found is far from perfect, but it is the new centerpiece of my Potomac collection.  This massive tooth measures 2 & 7/8ths inches on the slant.  Unfortunately I forgot to bring my camera with me, so no ground shot.  I wasn't expecting to be able to go out today, but I sure am glad I did!
