Saurosuchus galilei Saurosuchus (meaning "lizard crocodile" in Greek) is an extinct genus of rauisuchian archosaur in the family Prestosuchidae. With a length of around 7 m (23 ft), it was the largest rauisuchian, except perhaps for the less well known Fasolasuchus. Like other rauisuchians, Saurosuchus walked on four fully erect limbs. It lived in the Late Triassic of Argentina. Saurosuchus is one of the largest rauisuchians. The complete skeleton is not known and size estimates range from around 6 to 9 metres (20 to 30 ft) in total body length. It has a deep, laterally compressed skull. The teeth are large, recurved, and serrated. The skull is wide at its back and narrows in front of the eyes. The skull roof and maxilla are somewhat pitted, a distinguishing feature not seen in any other rauisuchian. Pitting is also seen in aquatic phytosaurs and crocodilians, but the ridges and grooves are deeper and much more extensive across the skulls of these forms. The frontal bones, located at the top of the skull, are enlarged to form thick ridges over the eyes. As in other rauisuchians, a small rod projects down from the lacrimal bone in front of the eye, but it does not attach firmly to the jugal bone below it. Ridges along the upper surface of the supraoccipital bone at the back of the skull are attachment points for strong neck ligaments. The cervical vertebrae are shortened and robust, forming a strong neck. Dorsal osteoderms run along the back of Saurosuchus. There are two rows to either side of the midline, with each leaf-shaped osteoderm joining tightly with the ones in front of and behind it. Length: 6 to 7 metres; Weight: 1 to 2 tonnes. ![]() Skorpiovenator bustingorryi Skorpiovenator is a genus of abelisaurid theropod dinosaur from the late Cretaceous period of Argentina. The type species, Skorpiovenator bustingorryi, is known from a single, nearly complete skeleton missing only most of the forelimbs and parts of the tail. The specimen was recovered from the lower part of the Huincul Formation in Patagonia, dating to the late Cenomanian stage, about 95 million years ago. It would have lived alongside other carnivorous dinosaurs such as the carcharodontosaurid Mapusaurus and another abelisaurid, Ilokelesia. The type specimen was described and named by Canale, Scanferla, Agnolin, and Novas in 2009 (though the paper was released as an advanced publication online in 2008). The name Skorpiovenator bustingorryi is derived from the Greek and Latin for "scorpion hunter," due to the abundant scorpions present at the dig site, and the specific name honors Manuel Bustingorry, who owned the farm where the specimen was found. The describers have defined a new name Brachyrostra for a clade, to which Skorpiovenator belonged. ![]()

^ agreed. I have a slight edge towards the theropod though |

Regarding saurosuchus size,
http://carnivoraforum.com/topic/9666022/2/ On the other hand, as skorpiovenator is seemingly around 6 m long, i would say it probably likely weighed less than 1 ton. For now, seeming that they are similar in size, i would back saurosuchus due to its more formidable bite. I tend to back rauisuchians over abelisaurids at parity. |

I voted saurons his because I don't know the size of the theropod |

I've interpreted what's been posted here as Saurosuchus was probably at or near a tonne after all. |

As always, a praiseworthy setup, and one which is difficult to analyze sufficiently. Off the bat, I give my edge to Skorpiovenator. Saurosuchus, somewhat typical of Rauisuchians (if exceptionally sized), was easily the most formidable terrestrial predator of its day, but namely, that was the late Triassic, and most of its prey items had diminutive statures. Being so horizontally disposed was obviously advantageous to speed and balance, but larger prey, such as those tackled by Abelisaurids, required greater height advantages if the cranium is the sole weapon. This is obviously the case for quadrupedal Saurosuchus, and is equally so for the stout-armed Skorpiovenator. That having been said, their jaws are extremely impressive, and both could deliver crushing forces, but the theropod was slightly longer, and although I am not the most suitable to speak on the matter, I do believe it had a slightly larger absolute skull size (something Abelisaurids are known for, at least by me ). Since the dinosaur (correct me if I'm wrong; I don't think suchians are dinosaurs) is taller, it could simply cease any opportunity to strike the Saurosuchus from either above or, maneuvering skillfully, below (granting it was probably ossified generously on the dorsal side, like Postosuchus). It would be more difficult for the Saurosuchus to initiate an offensive, because the legs of the Skorpiovenator are so far behind its head that they would not be viable targets, while anything else would be out of reach but by a lucky leap. The Skorpiovenator could probably dodge and position itself more easily, only having to rearrange two limbs rather than four.

I normally vote rausichians over similarly sized theropods. Because of this, I back Saurosuchus here.
