Paleontologists discover massive meat-eating dinosaurs
Issue date: 2/18/08 Section: News Briefs
Fossil hunters say they have discovered bones of two massive meat-eating dinosaurs in Africa.
In the journal Acta Palaeontologica Polonica, University of Chicago paleontologist Paul Sereno and co-author Stephen Brusatte named one Kryptops palaios, or "old hidden face," because of a horny covering over its face.
They named the other Eocarcharia dinops, or "fierce-eyed dawn shark," for its razor-sharp teeth and bony brow.
Both were about 25 feet long and stood 7 feet high at the hip. Kryptops had a short snout with teeth better for gnawing, leading the scientists to believe it was more of a scavenger.
Eocarcharia's brow was so pronounced that Sereno thinks it was used for head-butting rivals to win over potential mates.
Sereno's group found the new species during a 2000 expedition to the Niger desert. They found bones from about a dozen new species, and stumbled across one of the richest archaeological sites that's been found in the region.
"We have not released even half of all that we found there," Sereno said.
