I was going to write something clever about this nice and very “organic looking” stromatolite I found on Gotland this spring, but then I started to question if it really is a stromatolite and not a stromatoporoid? What do you think it is? I think its damn hard sometimes to tell the difference from these two fossils. Anyhow, its def Silurian if thats any help to experts out there. Im quite sure someone knows it better than me and I would appreciate the help with identification.
Stromatolite or Stromaporoid – I really like the details on it. Not just the color and the fine laminae, but all those small attached remains of bryozoans, brachiopods and roots of what nots.
