Noffke later came back with a team. The problem, of course, was to confirm whether these structures were indeed of biological origin. Noffke had developed a set of criteria to distinguish MISS, the product of microbe life, from mere geological phenomena. They include looking at shapes, micro-textures, and chemical composition. Noffke and her team had tested the criteria in previous studies comparing ancient MISS from other sites to modern MISS.

The MISS found in the Dresser Formation did fit the criteria, making them evidence for some of the earliest signs of life on Earth. The results of the study are published this month in the journal Astrobiology.
