The Jane specimen has become part of an argument that scientists have. The scientists disagree whether "Nanotyrannus" is really a separate genus of tyrannosaurids. Jane's skull is almost exactly the same as the skull of the original "Nanotyrannus" specimen, which means they are the same species. The Burpee Museum held a conference in 2005. Paleontologists came to the conference and talked about whether these "pygmy tyrants" were adults from a small tyrannosaurid species or young "Tyrannosaurus rexes". A few scientists thought they were adult small tyrannosaurids, but most of them decided they were probably young "T. rexes". However, scientists have not fully studied Jane yet. Robert Bakker is working on it with his colleagues Peter Larson and Phil Currie.
