I found this fish head and was wondering how old it might be. One side it looks like a layer of gills and the eye hole and then the mouth at the end. In the second picture the fish looks fresh but it is hard as rock, I just wet it so there would be more contrast between the rock and fish.
What you have there is a fossil coral, its definitely not a fish skull but please don't feel bad about mistaking it for one, Just making a basic I.D. is not always so easy & it takes a lot of practice before you start to get really confident .
