This Lunar and Planetary Science article provides information about cryptoendolithic life (microbes living within rocks on the Earth's surface) in Antarctic sandstones. The purpose of the study was to use chemical and isotopic methods to determine what influence the cryptoendoliths have on the rocks they live in. These cryptoendoliths are predominantly lichen that live in the pores between sand grains in sandstone. The article features a color photograph of the cryptoendolith as well as an image and diagram of data.
