http://news.discovery.com/animals/dinosaurs/t-rex-was-likely-an-invasive-species-160302.htm Honestly this is a little hard to take in seeing as how the author of this find was the one responsible for saying Nanotyrannus was a separate species from that NatGeo program. However, it is a nice idea to think about seeing as how any other tyrannosaurs just went extinct at the time T-rex showed up |

IIRC evidence suggests that quite a few dinosaur families in late Cretaceous North America may have originated in Asia (though correct me if I'm wrong), so T. rex would hardly be the only one.

Both authors, Carr and Brusatte, are of the quite strong opinion that 'Nanotyrannus' is a junior synonym of T. rex, so I don't know where you're getting this from. |

You sure? Well then who was the one featured in that documentary? EDIT: Nevermind that's Phil Currie I'm thinking about lol Edited by BossMan, Jake, Mar 2 2016, 02:47 PM.

I'll just dump what I said at ZTV here:
Slightly modified from the source post. Side note: The paleontologist behind the Nat Geo atrocities regarding Nanotyrannus is Peter Larson. Honestly I find his practices and scientific ethic to be an absolute disgrace - He's basically the reason we lost the death match T. rex specimen to private collectors. The Nat Geo documentary was basically his way of advertising the specimen for the auctions, and the whole thing was rigged anyway - pay note to how the likes of Carr, Currie, Holtz and Horner don't show up to make a case AGAINST Nano. Not only that, it so conveniently happens after he makes several public comments but no scientific papers about it too. It's like he wanted it out of scientific hands before someone had the chance to discredit his claims. The actions of a desperate man. He is also the reason why it cost 8 million US dollars (from I believe it was about a dozen sponsors) to bring Sue back into scientific hands. All because once it was found that Sue was uncovered on private property, Larson tried to con the landowner into selling it to him for 2000 USD, and he ended up losing the resulting court case.

To add insult to injury, Holtz—and possibly others, I can't quite recall—were actually brought in during production to speak about 'Nanotyrannus' and at the least advised caution in calling it a distinct genus. His/their interviews were cut from the final product. Hm. |

Well a lot of dinosaur families disappeared/became rarer in North America during late Cretaceous. Not just other Tyrannosaurs, Lambeosaurine and Centrosaurine too IIRC. Seems quite a stretch to blame everything on T. rex, considering many ecosystems went under major changes. |

I agree. The increase on the ecological conectivity of Laramidia after the WIS started to retreat and the subsequent redution of lowland wetlands and humid forests may had been a more likely culprit for the reduction/extinction of many families of Dinosaurs... That makes me wonder, we do know there was a big difference between the flora of the late Maastritchian in Hell Creek and the Campanian-Lower Maastritchian flora of Horseshoe Cannon. Could changes in flora further contribute to the decline of those groups of Dinosaurs? |

I suppose a floral change sorta comes with having all the lowland fern plains, conifer forests and boggy regions receding in exchange for an expansive beech forest. Caused a shift from an Albertosaurine-Lambeosaurine-Centrosaurine-Nodosaurid ecosystem to a Tyrannosaurine-Saurolophine-Chasmosaurine-Ankylosaurine one. |
