Earlier this week, I wrote that fungi are weird. Fungi are also old. Probably.
Recently discovered fossils from Arctic Canada have been interpreted as fungi, an important finding since the sediments in which they were found date to 0.89-1.01 billion years ago, around half a billion years older than the next oldest unambiguously fungal fossils. Corentin Loron and colleagues have described microfossils from the Grassy Bay Formation and presented several lines of evidence that they represent ancient fungi.
