Listing this because We Heart Dinosaurs in this town!

University of Chicago fossil hunters in Africa have discovered bones of two massive meat-eating dinosaurs that may have picked over the same prey, much as modern-day lions and hyenas do. 

In the scientific journal Acta Palaeontologica Polonica, paleontologist Paul Sereno and co-author Stephen Brusatte named one Kryptops palaios, or "old hidden face," because of a horny covering over its face.

The other, they named Eocarcharia dinops, or "fierce-eyed dawn shark," for its razor-sharp teeth and bony brow.
