LauraT Posted February 26, 2022 Share Posted February 26, 2022 (edited) Any idea why these little bones are blue? (I know the look a little green here but in sunlight they’re much more blue.) Found a very remote place in Central Turkey. Edited February 26, 2022 by LauraT 1 Link to comment Share on other sites More sharing options...
Mahnmut Posted February 26, 2022 Share Posted February 26, 2022 (edited) Hi Laura, Very cool find! I think it is what is called bone turquoise or odontolite, traces of the mineral vivianite colour the bone (or teeth). Vivianite is Iron phosphate, so is created when the calcium phosphate of the fossil reacts with iron from the surroundings under the right circumstances. Correction: I just read up on the topic and it seems that it may be rather Manganese ions than vivianite according to new research.

LauraT Posted February 26, 2022 Author Share Posted February 26, 2022 Thank you so much for that information! Any idea what kind of creature these may have belonged to? Link to comment Share on other sites More sharing options...
Mahnmut Posted February 26, 2022 Share Posted February 26, 2022 For that different views , preferably next to a measure, could help those who may know. About the right piece I do not even have a clue what kind of bone it may be.

SawTooth Posted February 26, 2022 Share Posted February 26, 2022 I am not sure but I believe that the coloration depends on what minerals the fossil is around, or what material the fossil is in. Another question I have is, can water, or just salt discolor the fossil and make it black? I ask this because I have noticed that teeth and bone that comes from beaches and creeks, especially that have saltwater fed into them, are typically more black than the white, blue, brown, and tan fossils from freshwater and land sites 1 Link to comment Share on other sites More sharing options...
LauraT Posted February 26, 2022 Author Share Posted February 26, 2022 That’s an awesome question. I wondered the same thing because I find black shark teeth all the time. Link to comment Share on other sites More sharing options...
