The major research that eradicates about dinosaur before this is to pass estimation the change of amount of different times dinosaur, its conclusion is recorded the influence of difference very easily by fossil. The group that Sidifen Bulusaite of home of paleontology of museum of American natural history heads used configuration difference to study dinosaur to eradicate first, its principle is, one is planted group in individual configuration difference is bigger, kind group overall and character is more healthy, have energy more.
