Tyrannosaurus rex
Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), commonly abbreviated to T. rex, is a fixture in popular culture. It lived throughout what is now western North America, with a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 67 to 65.5 million years ago.[1] It was among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two clawed digits. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it was the largest known tyrannosaurid and one of the largest known land predators. By far the largest carnivore in its environment, Tyrannosaurus rex may have been an apex predator, preying upon hadrosaurs and ceratopsians, although some experts have suggested it was primarily a scavenger. The debate over Tyrannosaurus as apex predator or scavenger is among the longest running in paleontology. Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, FMNH PR2081 ("Sue"), measured 12.8 metres (42 ft) long, and was 4.0 metres (13.1 ft) tall at the hips. Mass estimates have varied widely over the years, from more than 7.2 metric tons (7.9 short tons), to less than 4.5 metric tons (5.0 short tons), with most modern estimates ranging between 5.4 and 6.8 metric tons (6.0 and 7.5 short tons). Packard et al. (2009) tested dinosaur mass estimation procedures on elephants and concluded that dinosaur estimations are flawed and produce over-estimations; thus, the weight of Tyrannosaurus could be much less than usually estimated. Other estimations have concluded that the largest known Tyrannosaurus specimens had a weight exceeding 9 tonnes.

Spinosaurus aegyptiacus
Spinosaurus is a genus of theropod dinosaur which lived in what is now North Africa, from the lower Albian to lower Cenomanian stages of the Cretaceous period, about 112 to 97 million years ago. Spinosaurus may be the largest of all known carnivorous dinosaurs, even larger than Tyrannosaurus and Giganotosaurus. Estimates published in 2005 and 2007 suggest that it was 12.6 to 18 metres (41 to 59 ft) in length and 7 to 20.9 tonnes (7.7 to 23.0 short tons) in weight. The skull of Spinosaurus was long and narrow like that of a modern crocodilian. Spinosaurus is thought to have eaten fish; evidence suggests that it lived both on land and in water like a modern crocodilian. The distinctive spines of Spinosaurus, which were long extensions of the vertebrae, grew to at least 1.65 meters (5.4 ft) long and were likely to have had skin connecting them, forming a sail-like structure, although some authors have suggested that the spines were covered in fat and formed a hump. Multiple functions have been put forward for this structure, including thermoregulation and display. Dal Sasso et al. (2005) assumed that Spinosaurus and Suchomimus had the same body proportions in relation to their skull lengths, and thereby calculated that Spinosaurus was 16 to 18 meters (52 to 59 ft) in length and 7 to 9 tonnes (7.7 to 9.9 short tons) in weight. The Dal Sasso et al. estimates were criticized because the skull length estimate was uncertain, and (assuming that body mass increases as the cube of body length) scaling Suchomimus which was 11 meters (36 ft) long and 3.8 tonnes (4.2 short tons) in mass to the range of estimated lengths of Spinosaurus would produce an estimated body mass of 11.7 to 16.7 tonnes (12.9 to 18.4 short tons).

According to Therrier and Henderson the limit of bipedal animals would be 14 tons. They stated that Spinosaurus (with 175 cm) would be 20+ tons, however they had doubts and therefore they made estimates with 150 cm skull (12.5 m and 12 tonnes). I admit i don't like his skull/body length method. Personally i like more Dal sasso's one because length estimates are based on relatives rather than on unrelated dinosaurs like Giganotosaurus.
~14 metric ton Spinosaurus would be around 17 m in length (based on Suchomimus 11 m, 3.8 tonnes).

Ps. 19+ m and 20+ tons is your f****** bulls*** too ,not fact. So GTFO

He said that you should refute his info with 'facts', not his facts.

Spinosaurus mass estimates are so extrapolative that I've heard as low as 4 tonnes to as high as 20 tonnes. I change my mind I think is Spino is too big for rex.

But where is 19 m in any scientific paper? So the 19+ m is his just dream. Overrated d***'s dream!

I'm only a scratch of 35 cm a spinosaurus is a land t rex easily
thanks to these very muscular arms (given the size of the blades) 2 m


lol

lets resume that:
if one is resurrected as the biggest killer dino (I wonder how, and more importantly, doesn´t one have to be dead in order to be resurrected?), one changes ones mind (logical, I suspect most vegetarians would have to make major changes, and I guess one would also change ones mind about things like clothes and the use of public means of transport)...spinosaurus is large and thus it can be widely seen (while perfectly logical I cannot really see what it has to do with the first post), and his weapons win (that on the other hand doesn´t sound all that logical as weapons alone are pretty helpless)....larry is 35cm large, spinosaurus is as large as a country and T. rex does something that isn´t more precisely defined easily due to its very muscular arms

Did I understand that correctly? If not, what did it mean?

The new SuperGuerrero, although not as good, people could start using your quotes as sigs now, congratulations.

Now that was finally at least a phrase that one could understand! Keep up the good work and soon you will make complete sentences!

Just look at the size of the snout and head of Tyrannosaurus!  :o That should be a very useful weapon.
But is overcome by Spinosaurus' size and strength advantages...
And tyrannosaurus overcomes spinosaurus s abilities with skill, neck and leg muscles twice as powerful, and special weaponary.

Skill is irrelevant, Spinosaurus doesn't fight with it's neck, and Spinosaurus has stronger leg muscles, it needs to support a more massive body! How the hell can an animal only half the size have 2x stronger leg muscles!? Your "special weapons" for Tyrannosaurus are pure fantasy
