I found this 'rock' on the beach in Florida. It resembles a buckeye, but it is definitely not a buckeye. It has a sealed slit that extends about 3/4 of the way around, and it feels completely solid. Any idea what this is? 17 0 2009-11-04T17:12:17+00:00 false 1218 true 2010-03-11T23:01:39+00:00 2045 169
