Climate change causes cycad cones---first in 60m years.

Global heating: ancient plants set to reproduce in UK after 60m years

Last time this happened was just before a mass extinction....

 

I don't see that mentioned as such in the article. When you say "just before", what time frame are you talking about?

 

Should have said 'just after' shouldn't I? Thanks for pointing out my error.
No, this was not referred to in the article: I thought it to be pertinent.
Mass extinction: 65 million years ago.
Previous cycad cones: 60 million years ago.
In geologic terms, 5 million years is a eye-blink.
