Paleontologists at UC Berkeley discovered that three species of dome-headed dinosaur, (Dracorex, Stygimoloch, and Pachycephalosaurus wyomingensis) are actually the same species at different ages and maturity.
This has profound implication for the study of dinosaurs because it has the potential of changing the entire dinosaur fossil landscape. It also raises the question of what else have they missed. The fact is that this discovery could have implications that go way beyond dinosaurs after all the same mistake could have been made with other types of fossils. As a result this discovery could send waves through out the fossil record.
It also shows just how much evolutionists have botched their interpretation of the fossil record. How many so called transitional forms are juveniles particularly among amphibians.
