Re: Fungi and the Dinosaur Extinction: A New Article



Knowing what a problem fungal disease is for my pet birds, I can well
believe that it played a role in the environmental catastrophe that killed
them.  Atleast two common molds can give birds fatal pneumonia.    Fungal
disease is a common cause of illness and death in pet psittacine birds.

I really don't think it WAS the catastrophe, though.
