Triceratops and Torosaurus dinosaurs 'two species, not one' (BBC)

By Neil Bowdler
Science and health reporter, BBC News

A study has rejected claims that Triceratops and the lesser-known Torosaurus are one and the same type of dinosaur.

Research published in 2010 suggested the two-horned animals represented merely different growth stages, with Torosaurus the adult and Triceratops the youngster.

But researchers at Yale University say the fossils do not support the theory.

Details are published in the journal Plos One.

Nicholas Longrich and Daniel Field, of Yale University, looked at 35 specimens ascribed to both species and concluded they represented two distinct creatures.

The lumpers and the splitters are having at it again.

John R. "Jack" Horner (famous for Maiasaura eggs & nests, T. rex DNA, etc.) co-authored the original 'synonymy' paper.

Point of clarification: Triceratops and Torosaurus name different genera, not just different species (at least two species of each have been proposed).
