It’s almost like watching a train wreck. I love watching scientists trying to figure something out only to turn around and claim that they really don’t know anything.

To me, they could save so much time if they just admitted their ignorance in the first place. Ha!

This story comes from National Geographic

Far from besting their competitors in a long struggle to become Earth’s dominant land animals, dinosaurs may have just gotten lucky, new research suggests.

The first dinosaurs appeared during the late Triassic period about 240 million years ago.

Their main competitors were a closely related group of reptiles called the crurotarsans, from which modern crocodiles and alligators descended.

Crurotarsans and dinosaurs coexisted for about 30 million years. But about 200 million years ago, Earth suffered a mass extinction, possibly caused by rapid global warming.
