Fossils recently unearthed in Madagascar show that modern dental techniques evolved much too late. Alas, some dinosaurs had uncorrected buckteeth.
Most of the teeth in a newly described species of theropod were serrated and curved slightly toward the rear of the mouth. This pattern is typical for such dinosaurs, says Scott D. Sampson, a paleontologist at the University of Utah in Salt Lake City.
