Spinosaurus - Tyrannosaurus (average specimens)
I never did consider Jurassic Park III ( 2001 ) as delivering an accurate confrontation between T-rex and Spinosaurus.

Of all the big Theropods, Tyrannosaurus rex was the TANK. Comparisons of T-rex with other large carnivorous dinosaurs, such as Giganotosaurus, Carcharodontosaurus, and Spinosaurus can be seen at: wildfact.com/forum/topic-tyrannosaurus-rex

When I was a school boy, Tyrannosaurus rex was called, "King of the Dinosaurs" and, I haven't changed my mind.

Giganotosaurus vs Tyrannosaurus (average individuals) The bulk and bone-crushing jaws of T-rex vs the speed and meat-slicing teeth of Giganotosaurus.

Tyrannosaurus rex ( my favorite since I was a preschooler ) and Spinosaurus aegyptiacus: In a real face-off, Spinosaurus would be killed quickly by Tyrannosaurus rex - ( IMO )

Judging from the picture above, the T. rex wins easily.

Judging from the picture above, the T. rex wins easily. Our "image" of Spinosaurus has gone through a lot of changes over this past decade. He started out as a huge bipedal predator. Now, it is questionable whether or not he was capable of bipedal walking. His long narrow jaws and teeth are designed for catching fish. So yes, T-rex could probably kill him rather easily, I would think. In fact, I would wager that Carcharodontosaurus could and did prey upon Spinosaurus when it had the opportunity.

Spinosaurus with Carcharodontosaurus. Two massive predators that lived at the same time as each other and in the same place but had completely different ecological niches. Diagrams by Franoys *IMHO - Carcharodontosaurus was a predator; a true Carnosaur. Spinosaurus was a fish-hunter and shoreline scavenger. wildfact.com/forum/topic-spinosaurus-news?page=4 Carcharodontosaurus saharicus probably preyed upon Spinosaurus aegyptiacus when given the opportunity.

The mighty Tyrannosaurus rex was, during my childhood in the 1950s, called "the king of the dinosaurs" and for good reason. It seems that with each new really big dinosaur that comes along, that new monster is immediately stated as being bigger and badder than T-rex. Well, guess what... Tyrannosaurus rex is still the heaviest known predatory dinosaur thus far discovered. ( top picture T-rex with Spinosaurus / bottom picture T-rex with Giganatosaurus )

Top 5 biggest (and smallest) theropod dinosaurs www.sciencefocus.com/nature/top-5-biggest-and-smallest-theropod-dinosaurs/ The theropods were a diverse group of dinosaurs. They walked on two legs, were mostly meat-eaters, and all had three-toed limbs. Theropods all had hollow bones, something they have in common with their descendants, modern birds. They include the iconic T. rex, as well as Velociraptor, Spinosaurus and Compsognathus, of Jurassic Park fame. Top 5 heaviest theropod dinosaurs: 1- Spinosaurus aegyptiacus - Spinosauridae. 2- Tyrannosaurus rex - Tyrannosauridae. 3- Giganotosaurus carolinii - Carcharodontosauridae. 4- Tyrannotitan chubutensis - Carcharodontosauridae. 5- Mapusaurus roseae - Carcharodontosauridae.

Spinosaurus’ dense bones fuel debate over whether some dinosaurs could swim A new study suggests yes, but it won't be the last word www.sciencenews.org/article/spinosaurus-bones-dinosaur-swim-paleontology A fierce group of predatory dinosaurs may have done much of their hunting in the water. An analysis of the bone density of several sharp-toothed spinosaurs suggests that several members of this dino group were predominantly aquatic, researchers report March 23 in Nature. That finding is the latest salvo in an ongoing challenge to the prevailing view that all dinosaurs were land-based animals that left the realms of water and air to marine reptiles such as Mosasaurus and flying reptiles such as Pteranodon. But, other researchers say, it still doesn’t prove that Spinosaurus and its kin actually swam.

Spinosaurus dinosaur 'hunted underwater', new research finds - 23 March, 2022. www.bbc.com/news/uk-england-hampshire-60846702 The density of the bones of the largest ever carnivorous dinosaur prove that it hunted underwater, researchers say. A new paper explains how the Spinosaurus and its close relative Baryonyx had dense bones that allowed them to submerge themselves to hunt. "The bones don't lie," according to Portsmouth University palaeontologist Dr Nizar Ibrahim. Scientists have debated whether Spinosaurus pursued prey in the water, or snapped it up in the shallows. For the latest research published in Nature, a team including Dr Ibrahim and lead author Dr Matteo Fabbri from Chicago's Field Museum compared femur and rib bone cross-sections from 250 species of extinct and living animals. They included seals, whales, elephants, penguins, hippos, alligators, mice, hummingbirds, mosasaurs and plesiosaurs. Subsequently the scientists claim to have found a clear link between bone density and aquatic foraging behaviour. The animals that submerged themselves underwater to find food had bones that were almost completely solid throughout, while the bones of land-dweller had hollow centres. Dense bone is believed to help with buoyancy control. Previous research at Portsmouth University on Spinosaurus teeth also pointed to it being an "enormous river-monster". Dr Ibrahim, who unearthed parts of a Spinosaurus skeleton in North Africa's Sahara Desert in 2014, described it as having retracted nostrils, short hind legs, paddle-like feet and a fin-like tail. He said: "We battled sandstorms, flooding, snakes, scorpions and more to excavate the most enigmatic dinosaur in the world and now we have multiple lines of evidence all pointing in the same direction - the skeleton really has water-loving dinosaur written all over it." Spinosaurus aegyptiacus remains were first discovered about 100 years ago in Egypt. They were moved to a museum in Munich but destroyed during World War Two. Since then only fragments of Spinosaurus bones have been found. The dinosaur has enjoyed wider notoriety since 2001, when it bested a Tyrannosaurus rex in Jurassic Park III. Its UK cousin the Baryonyx was found in Surrey in the 1980s.

The Baryonyx, the UK close relative of the Spinosaurus, has similar characteristics.

The Spinosaurus had dense bones that allowed it to submerge itself to hunt, palaeontologists say.
