Paleontologists have  named both too many and too few dinosaurs. The tricky business of taxonomy is to blame. While hundreds of dinosaur species rest as-yet-undiscovered in geologic formations and museum collections, researchers also tussle over the identities of specimens given new names. The continuing academic struggle over whether Torosaurus and Nedoceratops really represent growth stages of Triceratopsreally represent growth stages of Triceratops is one such struggle, and, even among ceratopsid dinosaurs, isn’t the only debate. Paleontologists are also unsure about the identity of Ojoceratops fowleri, a poorly known horned dinosaur found in New Mexico.
