We used δ 1 3 C values to identify lichen metabolism in the globally distributed Early Devonian (409-386 Ma) macrofossil Spongiophyton minutissimum, which had been alternatively interpreted as a green plant of bryophyte grade or as a lichen, based on its morphology. Extant mosses and hornworts exhibited a range of δ 1 3 C t i s s u e values that was discrete from that of extant lichens. The δ 1 3 C t i s s u e values of 96 S. minutissimum specimens coincided with δ 1 3 C t i s s u e values of… Expand
