Waffling to some ... discovery to others

Scientists digging south of Denver say they have uncovered evidence of a lush and vibrant rainforest that emerged surprisingly soon after the asteroid collision that wiped out the dinosaurs 65 million years ago.
The fossils of more than 100 kinds of towering conifer trees, huge ferns and blooming flowers challenge scientists' long-held assumption that a desolate Earth took about 10 million years to recover from the catastrophe and sprouted only a few dreary plant varieties for a long time.
Instead, the finding suggests that plant life -- at least at this now-dry prairie along Interstate 25 -- was flourishing as early as 1.4 million years after the impact. Some of the tree fossils measure 6 feet in diameter.
