Albertosaurus sarcophagus Albertosaurus is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period, more than 70 million years ago. The type species, A. sarcophagus, was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named. Scientists disagree on the content of the genus, with some recognizing Gorgosaurus libratus as a second species.As a tyrannosaurid, Albertosaurus was a bipedal predator with tiny, two-fingered hands and a massive head with dozens of large, sharp teeth. It may have been at the top of the food chain in its local ecosystem. Although relatively large for a theropod, Albertosaurus was much smaller than its more famous relative Tyrannosaurus, probably weighing less than 2 metric tons. ![]() Yutyrannus huali Yutyrannus (meaning "feathered tyrant") is a genus of tyrannosauroid theropod dinosaurs from the Early Cretaceous of China. Three specimens of Yutyrannus huali found in the fossil beds of Liaoning Province are currently the largest known dinosaur fossils that preserve direct evidence of feathers. Yutyrannus contains a single type species, Yutyrannus huali, named and described in 2012 by Xu Xing et al. The generic name is derived from Mandarin Chinese yu (羽, "feather") and Latinised Greek tyrannos (τύραννος, "tyrant"), a reference to the classification as a feathered member of the Tyrannosauroidea. The specific name consists of the Mandarin huáli (华丽, "beautiful"), in reference to the beauty of the plumage. Yutyrannus were gigantic bipedal predators. The holotype and oldest-known specimen has a length of 9 metres (30 ft) and an estimated weight of about 1,414 kg (3,120 lb). Its skull has an estimated length of 905 millimetres (35.6 in). The skulls of the paratypes are 80 centimetres (31 in) and 63 centimetres (25 in) long and their weights have been estimated at 596 kilograms (1,310 lb) and 493 kilograms (1,090 lb) respectively. The describers established some diagnostic traits of Yutyrannus, in which it differs from its direct relatives. The snout features a high midline crest, formed by the nasals and the premaxillae and which is covered by large pneumatic recesses. The postorbital has a small secondary process, jutting into the upper hind corner of the eye socket. The outer side of the main body of the postorbital is hollowed out. In the lower jaw, the external mandibular fenestra, the main opening in the outer side, is mainly located in the surangular. ![]() __________________________________________________________________________
I can't find the weight for Dryptosaurus or a good imagine. So how about this instead? Edited by Taipan, Jun 30 2013, 08:49 PM.

Most theropod individuals we know, appear not to have reached full size. |

Oh alright then. Is it because of the injuries they get? |

it´s only natural that in a population of animals most don´t reach the maximum size. I´m pretty sure there where individuals of every extinct taxon growing significantly larger than the ones we found |

Makes sense, Theropod, but let's get back on-topic now. For this fight. I'd say 50/50. |

Looks like Albertosaurus would win this fight. I don't have much informations about Yutyrannus, this species is too fresh, does anyone have any decriptions about Yutyrannus (like teeth design, skull design). I saw many people stated Albertosaurus has stronger bite but i can't find any proof for that

https://encrypted-tbn1.google.com/images?q=tbn:ANd9GcTvkS1NppZSkEdbkPYZy1HIknzmjYrf6yZrFsiDHI0qNXV4ZEJ9fw to me it seems like it´s skull is more slender, more like primitive tyrannosaurs before they developed very robust skulls. the early tyrannosaurs resemble dromaeosaurs or allosaurs much more in terms of skull design and built. |

Yeah, you're right. Yutyrannus skull seems to be much less robust than Albertosaurus ![]() Albertosaurus skull looks much more formidable, and it probably has much stronger bite force too |

bite force isn´t everything, but I suspect due to it´s size advantage it will matter, as it is much more difficult for yuyrannus to cause damage to the more compact and heavier opponent than it is for albertosaurus |

I haven't said this doesn't include living animals, just that average in this case is not very representative. |

Yutyrannus has higher biteforce, and is more robust. Albertosaurus is just too famous(I wonder why) |

Da Fuq? Higher bite force my ass, there's no study on the bite force of Yutyrannus. If anything, judging from the skulls alone, it appears that Albertosaurus would have the higher bite force. Plus even if Yutyrannus did have a higher bite force I don't think it's teeth were suited for such a purpose. From what I know bone-crushing was an adaptation that evolved in the Tyrannosaurids not earlier Tyrannosauroids. Anyhow if you want to make a comparison using skeletals, why not try making it using skeletals from the same artists that way differences due to artistic taste and style are non existent (if it's possible). Is it me or are you becoming more like (former) broly except a whole lot nonsensical |
