If bacteria can do it- surely modern dinosaurs … err … chickens can do it as well…
http://sandbox.scp-wiki.net/transmuting-bacteria From: Kevin O'Malley Such a theory would be straightforward (but not cheap) to test. We contact Louis Kervran to see if he has any of those golden sample eggs still in storage, and submit them to the intense chemical testing that would be able to sift through whether they've got KH*CO3 or CaCO3 in them. If we could contact old Louie … hmm… that would be an anomaly in itself since he died in 1983. However, there could be eggs in storage somewhere. This would be a great test to do. A large percentage of the eggshell would be potassium, in the form known as potash, so it should be possible to check this out. As I recall – researchers in the US military actually replicated this work but there were others who could not replicate. Not sure what the military interest was ? K-rations ? :-)
