The Dinosaur-Killing Asteroid Birthed Today’s Rainforests – WIRED
Plant fossils from Columbia reveal the forests of the Cretaceous period were sparser and less humid than their modern-day counterparts.
Colombias rainforest looked very different 66 million years ago. At present, the humid and biodiverse ecosystem is jam-packed with plants and is covered in a thick, light-blocking canopy of leaves and branches. Notably, there are no dinosaurs.

The areas plant coverage was relatively sparse, and a bevy of conifers called it home.
