Hey all,
Noticed there was not much info on these here on the forum or online in general. All of these have been found washed in from the tide of New Jersey's Ocean City. From what I could find these belong to Sea Robins and are part of their skull. The larger and more complete one shows more in detail how this would have looked on the actual fish. If anyone has more information as to what potentially the age may be it would be much appreciated! From what I have read based on seashells, the black coloring is due to being trapped in the sand for high periods of time, I would assume the same principal applies to these.
