Well some specimens of giganotosaurus have shown to be bigger than t rex.

Spinosaurus lived in a desert so it would have less food and water thus causing the muscles and tendons to contract making it smaller. Giganotosaurus lived in the rainforest where there would be more food, thus making it bigger......

Are you applying modern climates to dinosaur species that lived millions of years ago?

Well Giganotosaurus did live in the jurassic and in one of the wettest parts of the world at that time. Spinosaurus lived in the cretaceous in one of the driest parts of the world so it would waste energy by being slow and bigger.

There are other factors to size in animals though. Size of prey would be one; area to hunt. Spinosaurous likely hunted fish, you need to be quick and agile to do that. Think of a grizzly bear swiping out a trout from a river. Like that but bigger.

Well do you think he had a hard time catching small, fast, fish? And a big dinosaur needs a lot of territory so to maintain a large enough population to support an entire species that eats fish and lives in a desert habitat you need to live on one huge coastline or a deep nile that can support enough fish for bigger fish and huge dinosaurs.

Does anyone still find the book "Predatory Dinosaurs of the World" to be accurate?

I mean it has a hefty load if information. According to it; Spinos weighted around 3-3.5 tons

But then again, data changes with each year

Vlad, how old is that book?
My Smithosonian Dinosaur Handbook from 2003 states Spinosaurus was 50 ft long and weighed 7.75 tons.

Are you dumb? The biggest carnivore was giganotosaurus (43-46ft), the heaviest was carcharodontosaurus( at least 2000 pounds heavier then any other carnivorus dinosaur), and the tallest was tyrannosaurus rex(18-24ft). Spinosaurus doesn't come first in any of those categories, so how can it " kick all the dinosaurs ass"

yes indeed, giganotosaurus and his relatives as well as all the Allosaurids were among the biggest.

t.rex is the biggest meat eating dinosaur bigger than gigantosaurus and all predators its a fact

Giant coelocanths up to 15 feet long have been dated to the same time and place where Spinosaurus existed (Africa, Early Cretaceous), so that seems like like a good enough food source for a gigantic carnivorous dinosaur.

Now, Baryonyx, a close relative, did have bones from a juvenile Iguanodon in its stomach, so it's likely that spinosaurids either were carrion eaters or opportunists who took small live nonaquatic prey when possible. It's even possible they were more in the crocodile niche than we realize, though I have a hard time imagining a spinosaurus ambushing anything from the water, given the size of that fin.

If you think Spinosaurus is cool, check out Baryonyx, Irritator(real name), and Suchimimus.

If any are on here over 30 or more years old , will remember that many dinosaur book depicted t.rex as between 45- 50 feet long and 18-20 feet tall. But up to date the largest is only 42feet in length. Theres no doubt in my mind t.rex wasnt the largest, but paleontologists have been experts in making size well beyond what the actual fossil reneals. Spinosaurus was large , but he was primarily a fish eater which is what his anatomy suggests t.rex was undoubtably a heavyweight brute maybe even the toughest. BUT YOU CANT CLAIM THE LARGEST SIZE WITHOUT MOST OF THE COMPLETE SKELETON
