Dinosaurs just can't get a break. First, a comet slams into the Earth and renders them extinct. Now a group of scientists wants to dramatically shake-up the dino family tree.
A new study, published this week in the journal Nature, proposes a major reordering of dinosaurs' evolutionary history.
The revised tree swaps around large subfamilies and adds a new branch for the Tyrannosaurus Rex and its ilk. The study also suggests that dinosaurs may have originated in the Northern Hemisphere, possibly in an area that is now Britain — not in South America, as scientists have long assumed.
