Cover Story: In this paper, we describe fossilized microorganisms found in open and sealed pore spaces in pillow lavas from the Troodos Ophiolite (91 Ma) in Cyprus. A fungal interpretation is inferred upon the microorganisms based on characteristic morphological features. The fungi lived while the rocks were part of the oceanic crust prior to the emplacement of the crust onto land. The living conditions of the fungi were reconstructed through investigation of mineralogy, fluid inclusions, and the fossils themselves. The fossils acted as nuclei for mineral growth like zeolites, as seen in the cover image. View this paper
