At low tide Seapoint Beach is a broad swath of dark brown sand and after rough seas often full of wrack--piles of various seaweeds and shells and tiny organisms that get rolled together at the high tide line. Yesterday the wrack line was wide and deep.
Crescent Beach is steeper, with little sand, and mostly rounded rocks of various sizes.
It is a fragment of a skull, likely from a fish(?). The "snout" end is about 1.5 inches wide and the length from the snout tip to the widest part at the other end is 3.5 inches.
