    There are branching and fusing curved filaments—including A- and H-shaped structures—and little branch buds that sometimes appear to be seeking each other out; hollow spheres solo or in chains (spores?) both integrated into filaments and at their termini; and two different gauges of fiber, implying at least two species. The fibers also lack internal walls called septa that often divide such tubes into cells.

    Several kinds of fungi today possess this exact suite of characters, while no other group of organisms does, the authors say. Furthermore, the curved and bent filaments seem to rule out any abiotic look-alikes. Studies of physical fungal fossil imposters shows that they are uniformly wide, while real fungi tend to be narrower and may come in multiple sizes.

    Outside evidence suggests a fungal interpretation is plausible. Molecular clocks, which use calculated rates of DNA mutation to estimate when various groups of organisms evolved, suggest fungi could be 0.9–1.5 billion years old.

    The authors hypothesize that soon after the cavities formed, structures like stalagmites, stalactites, and grapelike botryoids coated their walls, colonized and catalyzed by fungi and other microorganisms; large spheres in the fossils penetrated by the filaments could be some kind of symbionts—or food. Notably, modern cave formations bear similar microbes, including fungi that resemble the fossils.

    It is like Earth and its components are recording everything.
