CHICAGO (AP) -- A team of University of Chicago fossil hunters has discovered the bones of two massive meat-eating dinosaurs in Africa that may have picked over the same prey, much as modern-day lions and hyenas do.
Both were about 25 feet long and stood 7 feet high at the hip.
One had a short snout with teeth better for gnawing, leading the scientists to believe he was more of a scavenger.
The other's brow was so pronounced that paleontologist Paul Sereno thinks it was used for head-butting rivals to win over potential mates.
The creatures lived at a time when land bridges connected Africa to India and even Antarctica, which was then a temperate home to dinosaurs. But later Africa became isolated and its dinosaurs followed unique evolutionary paths that scientists have just begun to uncover.
