Revolutionary overhaul of dinosaur family tree proposed 

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