Hello, does anybody have a clue of what type of fish these scales may belong to? The specimen is part of a fish skin cemented together with sand and pebbles, found on a beach in southern Brazil. Fossils of Pleistocene mammals and marine organisms are commonly found along the beach, but these scales are unlikely those of the largest marine fishes (Micropogonias furnieri and Pogonias cromis) that inhabit this area. Although similar in size, the scales of these species are ctenoid, whereas the fossil scales seem all cycloid, much thicker (~2-3 mm) and formed of stacked laminae.

Dear Guys, I recently found these teleost scales in flint erratics, they are between 3 and 6 mm length. The location is Varena otwn, South Lithuania (the Baltic region), flint erratics in our area are usually Late Cretaceous or Paleocene in age. the scale with brush like top has many point like surface elements in middle and upper part, only in bottom it has growth lines or circuli. Please help to identify some orgers or families of these fish remains. Any help will be appreciated! Best Regards Domas
