Argentinosaurus huinculensis
Was T Rex the biggest dinosaur?
Canadian T. Rex is Officially the Biggest Ever. The massive dinosaur also lived longer than any other T. rex discovered to date. The towering and battle-scarred ‘Scotty’ reported by UAlberta paleontologists is the world’s largest Tyrannosaurus rex and the largest dinosaur skeleton ever found in Canada.
Was a Spinosaurus bigger than a T Rex?
Finding Spinosaurus: A Dinosaur Bigger Than T. Rex. A century ago, scientists unearthed fossils of a gigantic carnivorous dinosaur bigger than Tyrannosaurus rex in the Sahara desert, but until recently, paleontologists thought the fearsome beast was lost to history.
What was the biggest meat eater?
Biggest Meat-Eating Mammal of All Time
- Blue Whale. Without dispute, the blue whale is the largest meat-eating mammal ever to exist on the planet.
- Andrewsarchus. Only one skull has ever been found, but based on its massive size the extinct Andrewsarchus is believed to have been the largest carnivorous land mammal ever.
- Southern Elephant Seal.
- Bear.
What was the deadliest dinosaur?

- Velociraptor mongoliensis.
- Tyrannosaurus rex.
- Mapusaurus roseae.
- Ankylosaurus magniventris.
- Allosaurus.
Is a blue whale bigger than dinosaurs?
Now paleontologists have announced a species proposed to be most massive dinosaur ever discovered: an enormous herbivore estimated at over 120 feet long and weighing over 70 tons—or longer than a blue whale and heavier than a dozen African elephants.
Have they ever found a full T rex skeleton?
Sue is the nickname given to FMNH PR 2081, which is one of the largest, most extensive and best preserved Tyrannosaurus rex specimen ever found, at over 90% recovered by bulk.It was discovered in August 1990, by Sue Hendrickson, an explorer and fossil collector, and was named after her.
Is a Giganotosaurus bigger than T Rex?
Today, Giganotosaurus is believed to have been slightly larger than T. rex, though even Giganotosaurus ranks behind Spinosaurus in size among the meat-eating dinosaurs.
What dinosaurs are bigger than T Rex?
More gigantic than Giganotosaurus. Spinosaurus was larger than both T. rex and Giganotosaurus, which was previously the largest carnivorous dinosaur known. But it’s unclear just how big Spinosaurus was, due to incomplete fossils.
Is Spinosaurus related to crocodiles?
It was Spinosaurus aegyptiacus, a 50-foot long creature with powerful jaws and a solid, spiny sail on its back that dwelled in Northern Africa 95 million years ago. But even though paleontologists have known about this particular dinosaur for almost a century, its true form has only just been revealed.
What is the T Rex closest living relative?
T. Rex Linked to Chickens, Ostriches. The closest living relatives of Tyrannosaurus rex are birds such as chickens and ostriches, according to research published today in Science (and promptly reported in the New York Times).
Did T Rex have good vision?
Among coelurosaurs, tyrannosauroidea had the best eyesight. The position of their eyes suggests that they had a very well developed sense of vision. The eye position of Tyrannosaurus rex was similar to that of modern humans, but their eyes and optic lobe were much larger than that of modern humans.
Why is T Rex the most famous dinosaur?
Aside from being one of the largest of the known carnivorous dinosaurs, Tyrannosaurus rex — T. rex, for short — is the dinosaur that has arguably received the most media exposure. It had a starring role in the “Jurassic Park” movies and has a renowned exhibit at the American Museum of Natural History in New York City.
Did the T Rex have any predators?
By far the largest carnivore in its environment, Tyrannosaurus rex was most likely an apex predator, preying upon hadrosaurs, armored herbivores like ceratopsians and ankylosaurs, and possibly sauropods. Some experts have suggested the dinosaur was primarily a scavenger.
What are the Spinosaurus predators?
Other marine predators you’re probably thinking about, such as plesiosauruses, were reptiles, not dinosaurs. Living 95 million years ago during the Cretaceous, Spinosaurus was also the only known four-footed dinosaur predator. Its peers, like T. rex, Allosaurus and Giganotosaurus, stood upright on their hind legs.
What is the dumbest dinosaur?
- The Dumbest Dinosaur. Stegosaurus had a brain the size of a walnut – only 3 centimetres long and weighing 75 grams.
- The Tallest Dinosaur. The tallest dinosaurs were the Brachiosaurid group of sauropods.
- What do you get if you cross a Brontosaurus with fireworks? Dino-mite!
Is the T Rex the strongest dinosaur?
Dinosaur still no match for prehistoric “megatooth” sharks. Once the largest known carnivore on land, Tyrannosaurus rex also had the most powerful bite of any terrestrial animal of any time period, a new study suggests.
Why are T Rex arms so short?
The precise purpose of T. rex’s relatively tiny arms has long been mysterious. Over the years, scientists have suggested that they might have been used to grasp struggling prey, to help resting dinosaurs push themselves up from the ground, or to grip tight to mates during sex.
Was there anything larger than a blue whale?
As the biggest animal ever to have lived, the blue whale (Balaenoptera musculus) seemingly obliterates any other animal’s chances at the length title. Even a new-born blue whale is longer than a giant reticulated python. The largest blue whales are found in the southern hemisphere.
Was Megalodon bigger than a blue whale?
Monster-size sharks in The Meg reach lengths of 20 to 25 meters (66 to 82 feet). That’s massive, although a tad smaller than the longest known blue whales. Scientists have made estimates of how big C. megalodon got, based on the size of their fossil teeth. Even the largest reached only 18 meters (about 60 feet).
Are blue whales the biggest animal ever?
Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet long and upwards of 200 tons. Their tongues alone can weigh as much as an elephant.
How fast can a Giganotosaurus run?
50 km/h
Adult
What is the bite force of at Rex?
When Bates and Falkingham used computer models to simulate T. rex’s bite, the result was “quite surprising,” Bates told us: a maximum bite force of almost 12,800 pounds, about the equivalent of an adult T. rex’s body weight (or 13 Steinway Model D concert grand pianos) slamming down on its prey.
How fast does at Rex run?
That’s why gigantic animals like elephants usually aren’t the fastest runners on the block, at least compared to their size. Despite this, many scientists have estimated that the enormous T. rex could run at speeds up to 45 miles per hour. But those figures were just guesses based on eyeballing the dinosaur’s body.
Do dinosaurs have hands?
Bird wings clearly share ancestry with dinosaur “hands” or forelimbs. A school kid can see it in the bones. But paleontologists have long struggled to explain the so-called digit dilemma. Later theropods had three, just like the birds that evolved from them.
Was Spinosaurus a quadruped?
Although traditionally depicted as a biped, it has been suggested since the mid-1970s that Spinosaurus was at least an occasional quadruped. It was therefore proposed that Spinosaurus was poorly adapted for bipedal terrestrial locomotion, and must have been an obligate quadruped on land.
Can Spinosaurus swim?
With flat-bottomed feet for pedaling, dense bones to regulate buoyancy, and retractable nostrils far back in its skull, Spinosaurus aegyptiacus may have hunted its prey both on land and in lakes and rivers. Coupled with the foot and bone adaptations proposed, the adaptations would have made it a fearsome swimmer.
