Dinosaur Divorce

I remember when I had to relearn how long humans had been on the North American Continent. Now this!
- - -

Some of the best-known dinosaurs, like Tyrannosaurus rex and Brontosaurus, may be headed for a divorce due to irreconcilable differences.

Scientists on Wednesday proposed a radical overhaul of the dinosaur family tree first laid out in 1888, concluding after an analysis of 75 species that the meat-eating group that includes T. rex should not be lumped in with the long-necked, long-tailed, four-legged plant-eaters like Brontosaurus.
The proposed new family tree includes two reformulated categories, or clades, of dinosaurs to replace the two that paleontologists have long recognized. The research also pushes dinosaur origins back to relatively soon after a mass extinction that rocked the Earth 252 million years ago.

I know the feeling. Man's arrival in Australia keeps getting put back too. Now it is 50000 years ago - fortunately Captain Cook's arrival remains exactly the same.

Re: Dinosaur Divorce

Along with learning the names and flags of all the new Countries and the fact that Pluto is no longer one of our planets. Were we wasting our time at school?

Plus six new cloud formations (one of them man made).
