So I found these after a storm came through the beach yesterday. Any idea what they are?? I'm pretty sure they're bone but other than that I have no clue... Thanks!!
The structure of the bone, shown particularly well in the smaller bone on the lower photograph, would indicate these are from a fish or reptile. They both appear symetrical which suggests that they are from a midline structure. There are four midline structures, the skull, sternum, spine and pelvis. I favour the skull cap of a fish.
