Decuriasuchus quartacolonia Decuriasuchus is an extinct genus of prestosuchid rauisuchian from the Middle Triassic period (Ladinian stage). It is a carnivorous archosaur that lived in what is now southern Brazil, in Paleorrota. It was first named by Marco Aurélio G. França, Jorge Ferigolo and Max C. Langer in 2011 and the type species is Decuriasuchus quartacolonia. The generic name means "legion of ten crocodile" in Greek in reference to the ten known specimens and the animal's possible group behavior. The specific name refers to the Quarta Colonia region where the fossils were collected.Decuriasuchus is known from ten specimens, including nine articulated and associated skeletons, three of which have nearly complete skulls. The holotype MCN PV10105a consists of an articulated partial skeleton, lacking scapular girdle and limbs. Eight specimens associated with the holotype, MCN PV10105b-i, and the tenth specimen (MCN PV10004), consists of cranial remains from a different spot in the same locality. The specimens were found in the Alemoa Member of the Santa Maria Formation, Rosário do Sul Group. The discovery locality is Rio Grande do Sul, Brazil. Like other rauisuchids, Decuriasuchus was a quadrupedal carnivore that was one of the top predators of its environment. It grew to a length of around 2.5 metres (8.2 ft). Decuriasuchus is closely related to the genera Prestosuchus and Batrachotomus. A phylogenetic study of the genus placed it in the family Prestosuchidae, but found the Rauisuchia group to be paraphyletic. The study was based on an earlier 2010 analysis of archosaurs. A later study involved adding Decuriasuchus to a 2011 analysis of archosaur relationships; D. quartacolonia was recovered as the basalmost member of the clade Loricata (the most inclusive clade containing Crocodylus niloticus but not Poposaurus gracilis, Ornithosuchus longidens or Aetosaurus ferratus). As a rauisuchian, Decuriasuchus is a distant relative of modern crocodilians. Nine specimens of Decuriasuchus were found in close proximity to each other. A study of the taphonomy of the site (the conditions under which the skeletons became fossilized) indicates that the assemblage represents the single burial of multiple individuals rather than the collection of unrelated remains in one spot over a longer period of time. The congregation of nine individuals in one area suggests that they may have been traveling in a group. If this were the case, Decuriasuchus would be the earliest known archosaur to exhibit group behavior. Komodo Dragon - Varanus komodoensis The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a large species of lizard found in the Indonesian islands of Komodo, Rinca, Flores, Gili Motang and Gili Dasami. A member of the monitor lizard family (Varanidae), it is the largest living species of lizard, growing to a maximum length of 3 metres (9.8 ft) in rare cases and weighing up to around 70 kilograms (150 lb). Their unusual size has been attributed to island gigantism, since there are no other carnivorous animals to fill the niche on the islands where they live. As a result of their size, these lizards dominate the ecosystems in which they live. Komodo dragons hunt and ambush prey including invertebrates, birds, and mammals. Their group behaviour in hunting is exceptional in the reptile world. The diet of big Komodo dragons mainly consists of deer, though they also eat considerable amounts of carrion. In the wild, an adult Komodo dragon usually weighs around 70 kilograms (150 lb), although captive specimens often weigh more. The largest verified wild specimen was 3.13 metres (10 ft 3 in) long and weighed 166 kilograms (370 lb), including undigested food. The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced serrated teeth that can measure up to 2.5 centimetres (1 in) in length. ![]()

Decuriasuchus looks rather skinny, and it's legs are really thin. I back the lizard here because I think that it's venom will kill it rather quickly and once it bites it, the rausichian will be paralyzed |

sorry. as for this for this fight, i'm not completely sure. i think it's a 50/50 match with two similarly sized creatures. the jaws on decuriasuchus looks ruthless and capable to deliver just as deadly damage as the monitor |
