Seán Jordan @seanfj.bsky.social · 22/01/2026It was a joy to contribute to this paper led by @sandyheth.bsky.social, Corentin Loron and Laura Cooper. We show the Devonian fossil, Prototaxites, is not a fungus but is in fact an organism from an as yet unknown extinct eukaryotic lineage. www.science.org/doi/10.1126/... @dcu-lsi.bsky.socialscience.orgPrototaxites fossils are structurally and chemically distinct from extinct and extant FungiPrototaxites fossils are distinct from Fungi, suggesting that they represent an extinct lineage of eukaryotic life. 0147
