Saurophaganax maximus Saurophaganax ("lizard-eating master") is a genus of allosaurid dinosaur from the Morrison Formation of Late Jurassic Oklahoma (latest Kimmeridgian age, about 151 million years ago). Some paleontologists consider it to be a species of Allosaurus (A. maximus). Saurophaganax represents a very large (13 metres (43 ft) long). Saurophaganax was one of the largest carnivores of Late Jurassic North America. Ray even gave an estimate of the body length of fifteen metres and Chure of fourteen, though later estimations have been lower. The fossils known of Saurophaganax (both the possible New Mexican material and the Oklahoma material) are known from the latest part of the Morrison formation, suggesting that they were either always uncommon or appeared rather late in the fossil record. Saurophaganax was large for an allosaurid, and bigger than both its contemporaries Torvosaurus tanneri and Allosaurus fragilis. Being much rarer than its contemporaries, making up one percent or less of the Morrison theropod fauna, not much about its behavior is known. Stovall in Oklahoma also unearthed a considerable number of Apatosaurus specimens, a possible prey for a large theropod. ![]() Torvosaurus tanneri Torvosaurus (play /ˌtɔrvɵˈsɔrəs/) is a genus of large theropod dinosaur that lived during the Late Jurassic period (mid-late Kimmeridgian stage in North America, early Tithonian stage in Europe). The name Torvosaurus means "savage lizard" and is derived from the Latin torvus ("savage") and the Greek σαυρος/sauros ("lizard"). Fossilized remains of Torvosaurus have been found in North America and Portugal. Torvosaurus reached 9 to 11 meters (30 to 36 ft) in length and an estimated weight of about 2 metric tons (2.2 tons), which made it the largest carnivore of its time, except for Epanterias (which may have been just a big Allosaurus) and Saurophaganax.The size of Torvosaurus is not definitely known because only incomplete material has been found, but it was a large theropod. North American Torvosaurus material is estimated as belonging to an individual about 9.0 meters long (29 ft), with a weight of about 1.95 metric tons (2.15 tons). Material from Portugal indicates even larger animals. In 2006 a nearly complete maxilla found in Portugal was assigned to Torvosaurus tanneri. It measured 63 cm in length (2.13 ft), significantly larger than the 47 cm (1.54 ft) long maxilla of the American specimen (total skull length 118 cm [3.87 ft]). Based on this, a skull length of 158 cm (5.18 ft) was estimated for the Portuguese specimen. This is comparable to the largest T. rex skulls, and makes Torvosaurus the largest known Jurassic theropod (surpassing Saurophaganax/Allosaurus maximus and Edmarka), and among the largest of all theropods. A partial femur from another individual belongs to an animal estimated as 11 m (36 ft) long. ![]() __________________________________________________________________________

http://upload.wikimedia.org/wikipedia/commons/thumb/e/e8/Torvosaurus_tanneri_skeleton.JPG/800px-Torvosaurus_tanneri_skeleton.JPG http://www.kheper.net/evolution/dinosauria/T_tanneri.gif this most closely resembles what I think it looked like. Bulkier, more tyrannosaurid- and less snake- like, what the robust parts I have seen seem to suggest. I would increse the neck muscularity though, also more similar to the amount of muscle tyrannosaurids are reconstructed with, the skull seems too large compared to the neck. There is an odd trend of restoring every non-T. rex neck as gracile and weak. Edited by theropod, Aug 14 2013, 07:32 PM.

Really? Look here. Seems like he updated it. Anyway, that's what he said about Torvosaurus: |

This is very close. I think Trovosaurus was a bit bulkier. So I favor it. |

Saurophaganax win due to respectable a size advantage. |

What superior weaponery do you mean? It'd need a size advantage for that. Surely it's skull is proportionally longer, but that's about all (I don't see people running around and saying Giganotosaurus has superior weaponery to T. rex because it has a longer cranium). Advantageous in some regard, but when viewing the whole picture you'll see it's a payoff. Is Edmarka included here? If not, Saurophaganax should have the advantage due to superior size. |

Torvosaurus at 40 feet. It would have had an extremely strong bite and they're pretty much neck in neck everywhere else. |

Bite force is not the determining factor in such a fight. How potent the bites were...I'm inclined to say they are evenly matched at weight parity. But, Torvosaurus wasn't 12m unless, perhaps, if we include Edmarka. |

Edmarka probably wasn't larger, it doesn't look like there is a lot evidence for the 12 m figure: http://carnivoraforum.com/single/?p=8464291&t=9593952 |

saurophaganax wins. it is significantly bigger, though at parity it would be a close match. at max weights saurophaganax wins 65/35. |

i agree but 15 m is unlikely i consider sauro to be 11 m and 4.5 t the other estimates are unlikely to me Edited by Jaws, Sep 29 2015, 09:05 AM.

Sauro wins due to sheer size. |
