I need to identify ornamented fish bone elements. The ornamentation is glossy like ganoin, in thick and wide, longitudinal striae on the outer surface of the bones. The bones themselves are similar to fin rays, however, I am not sure.
Yes, there are several publications out there that could be useful to you, but I need more information about your specimen in order to help. Where/when does it come from? What is the palaeoenvironment thought to be? Are you able to upload (or e-mail me) photographs of the specimen?
