Sauroposeidon was massive and probably grew to 18.5 metres tall making it the tallest dinosaur.
Its name, Spinosaurus, means “spine lizard.” This refers to the large, spiny, fin-like sail on top of its back, at least 6 feet tall. The Spinosaurus is the largest carnivorous dinosaur we know of.
Paleontologists have reported that a Tyrannosaurus rex unearthed in Canada – nicknamed “Scotty” – is the world's largest so far, at 43 feet (13 meters) long.
The huge dinosaurs called sauropods are astounding. So massive! So tall! Such long necks and tiny heads!
Brachiosaurus was an unusual dinosaur that lived 155.7 million to 150.8 million years ago during the mid- to late Jurassic Period. Specimens have been found primarily in the fossil-rich Morrison Formation in North America, but the dinosaur did not resemble any of the others that roamed the region.
The Struthiomimus may have been the fastest dinosaur. It could run up to 60 miles per hour! The Liaraptor ran until it took off into the air! These may have been the first dinosaurs to fly!
of one very big extinct animal, Tyrannosaurus rex. The most famous of the upright, largely meat-eating dinosaurs called theropods, T. rex would have weighed between 5,000 and 7,000 kilograms (11,000 to 15,500 pounds) with skin and flesh on its huge bones. That's about as much as the largest African elephant.
In a fight between Giganotosaurus and T-Rex, the Tyrannosaurus would win. The two dinosaurs are pretty similar to one another, but their approaches to fighting would make a world of difference.
A new hybrid dinosaur species created by the Jurassic World genetics team, Indominus rex is huge, ferocious, and filled with unknown potential. At 43 feet long and 18 feet tall, this one-of-a-kind beast is even larger than a T.
Rex—And First Dinosaur Known to Swim. Fossils paint the most complete picture yet of the ancient swamp creature's predatory life.
The new dinosaur, dubbed Siats meekerorum, is part of a group of giant predators known as carcharodontosaurs, and it's only the second of this group to be discovered in North America.
Scientists have discovered a new apex predator from the dinosaur era — a carnivore with shark-like teeth that was bigger than the T. rex. This apex predator is called the Ulughbegsaurus uzbekistanensis, or Ulugh Beg for short.
Troodon had a large brain for its relatively small size and was probably among the smartest dinosaurs. Its brain is proportionally larger than those found in living reptiles, so the animal may have been as intelligent as modern birds, which are more similar in brain size.
The two creatures never existed at the same time. Since the T-Rex lived later than the Spinosaurus, it is the most well-known species of Tyrannosaurus and scientists know much more about it.
If woolly mammoth will charge Tyrannosaurus first, then trex is dead. Trex is will win only in umbush. If they both of the one size then mammoth obvious will win.
rex reigns supreme in the dinosaur battle ring. Its powerful bite could generate between 8,000 to 12,000 pounds of force, said Evan Johnson-Ransom, a vertebrate paleontologist completing his master's degree at Oklahoma State University Center for Health Sciences.
Indominus rex would beat a Tyrannosaurus Rex in a fight. The I-rex was built to be the most powerful predator on the planet, and we have a very good simulation in the form of Jurassic World of what would happen in such a fight, and it's not good for the T-rex. Indominus rex is bigger, faster, and probably longer.
Mammoths were much more heavily built and while in height and length they were smaller, they were wider and heavier than T. Rex. Also, while T. Rex did pray on animals the mammoth's size or larger, the closest comparison is the triceratops with the forward facing horns.
Dreadnoughtus. Dreadnoughtus, the largest dinosaur whose size can be calculated reliably. A very complete fossil of this sauropod was unearthed in 2009. In life Dreadnoughtus was 26 metres (85 feet) long and weighed about 65 tons.
rex clocked a top speed of 30 miles per hour and a walking speed between 4.5 and 6.7 miles per hour, reports Jeff Spry for SYFY Wire. Now, researchers from the Netherlands have used computer reconstructions of a T. rex tail to estimate that the walking speed of the carnivore was much slower.
Tyrannosaurus Rex – About 20 mph. Velociraptor – About 25 mph (with 40 mph sprint)
For the past twenty years, Eoraptor has represented the beginning of the Age of Dinosaurs. This controversial little creature–found in the roughly 231-million-year-old rock of Argentina–has often been cited as the earliest known dinosaur.
rex, nicknamed “Scotty” in honor of a celebratory toast of scotch raised upon its discovery, the biggest member of its species ever found, but it also holds the distinction of being the longest-lived T. rex identified in the fossil record to date.
