This fossil was found on one of Sweden's more well known Islands Gotland during my holiday travels. This Island Is rich In fossils from the Silurian period. What confuses me Is the pattern that looks just like a Favosite or Honeycomb coral yet the shape resembles that of a shell from a turtle? It Is oddly symmetrical, as the pattern mirrors pretty much from the center of the fossil. I can not see any underlying structures. What Is this? P.S - I have zero expertise with fossils of any kind.
