Abstract Tyrannosaurus was a massive carnivorous dinosaur which existed for roughly 2 million years in North America prior to its extinction at the end of Cretaceous Period. It recently proposed by Gregory Paul and colleagues that fossil specimens historically attributed species T. rex represent three species, not one. This conclusion reflects an essential problem palaeontology defining recognizing boundaries. In this study we test T1 hypothesis imperator , regina single (recognising that, per International Code Zoological Nomenclature nomen (1905) has precedence over ). Based on analysis skull postcranial dimensions iconic application probabilistic morphometric definition as described Thackeray & Dykes, our results indicate high probability conspecificity, thus supporting hypothesis.
