Fungi Bloomed Twice around End-Cretaceous Mass Extinction
Fungi Bloomed Twice around End-Cretaceous Mass Extinction
By studying fungal microfossils in 66-million-year-old rock samples from the Denver Basin in Colorado, Johns Hopkins University microbiologists have confirmed that the dinosaur-killing asteroid impact triggered a worldwide fungal takeover, and uncovered a second, previously unknown ecological crisis just before it.
