The aim was to detect the possible presence of ancient bacteria encapsulated inside fluid and solid inclusions present in the calcium sulfate matrix from its formation.

Using sterile methods, the researchers were able to extract and reanimate these organisms, which are not closely related to anything in the known genetic databases.~ Wikipedia from, https://en.wikipedia.org/wiki/Cave_of_the_Crystals
