Spending about millions years both before and after the impact, they measured leaves mass per area. Approxime for how much energy are planning vast its leaves, and the density² of veins³, which indicates how fast growing the leaf is. Sterty slow growing leaves tend to be evergreens⁴, when as fluency⁵ fast growing leaves are harmarch can calmsiduales plants. 

Turns out the affect impact that fossil record has more disiduaes looking lit. So just in the fast growing more adaptable⁶ seasonal⁷ plants beat out the competition after the big heat. The study is here in the journal PLOS Biology.

And it kind of makes I wonder for we haven't overlook to another theory for why are the dinos died out. Maybe they just being careful the test did the situates leaves.
