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. ![]() __________________________________________________________________________

Torvosaurus 55-60%, Torvo has a stronger, bigger bite and possibly longer teeth. Saurophaganax doesn't really have any kind of intelligence advantage, both probably were very similar intellectually speaking. No speed advantages I can see, although if there was it'd go to Torvo. I dont see Saurophaganax winning most of the time, it could exploit it's larger size to knock over Torvo and go in for the kill but I see that scenario unlikely |

Sauro is a big allosaurus and torvo kills allosauri |

Yes I know it's larger i egnologed that in my previous post, I even said Sauro has a chance because of it's slight size advantage |

![]() The larger Saurophaganax is the upper size estimate of 15m, the smaller is the lower estimate of 13m Torvosaurus: 12m and 11m Edited by Taipan, Jul 16 2012, 09:10 PM.

Acroc. is (way) too big for Saurophaganax. What about this one? |

Acrocanthosaurus isn´t bigger than Torvosaurus, and I don´t see why it should be too big for Saurophaganax (with all those indices for sizes of up to 15m) |

OMNH 1708 (10.9 m) isn't way smaller (at least in terms length and height) than the largest Acrocanthosaurus (OMNH 10168) which measured 11.5 m. However OMNH 1935 (largest Saurophaganax) would measured around 13 m in length and weight ~5.5 tons (based on Allosaurus USNM 4734's humerus, the A. fragilis specimen is 7.4 m and 1.01 tons according to Theropod database). I think Saurophaganax maximus would win against Torvosaurus tanneri without doubt. Saurophaganax was more clever, faster, bigger and more advanced theropod. Torvosaurus had stronger bite though and bulkier built, but i think it is still 65/35 or a bit more for large Saurophagnax |

I think the european Torvosaurus wins this. The wimpy american version loses though |

European Torvosaurus would be 12 m, maybe 13 m. Probably it was heavier and (maybe) stronger than Saurophaganax. However Sauro would still have some advantages over it like speed and agility. Then it would be 50/50 for both.

I didn´t even know that there were other described specimens of saurophaganax (OMNH 1935) than NMMNH P-26083 and OMNH 1708. that´s finally the explanation for Holtz estimate and for the 14m (Chure) and 15m (Ray) estimates. No wonder that many people consider it so small when some sites left out specimens. |

Saurophaganax would win with size advantage and axe head... 15-meter long Saurophaganax wins 85% 13-meter long Saurophaganax wins 60% |

Torvosaurus isn't bulkier than Saurophaganax ![]() ![]() Torvosaurus is tooo overrated, Saurophaganax wins, larger, stronger, deadly hatcheted bite Edited by Verdugo, Sep 24 2012, 02:47 PM.
