The massive predator, nicknamed “Scotty,” was about 42 feet long and likely weighed more than 9.7 tons, according to the study published last week in the peer-reviewed journal The Anatomical Record.
What was the biggest fossil ever found?
The towering and battle-scarred “Scotty” is the world’s largest Tyrannosaurus rex and the largest dinosaur skeleton ever found in Canada. Researchers discovered unknown species at the Qingjiang fossil site on the bank of the Danshui River, near its junction with the Qingjiang River in Hubei Province, China.
What is the biggest T rex ever found?
Paleontologists at the University of Alberta recently reported the world’s largest Tyrannosaurus rex, and the biggest dinosaur skeleton ever found in Canada. The enormous dinosaur, which was 42 feet long and weighed 19,400 pounds, roamed prehistoric Saskatchewan 66 million years ago and was nicknamed Scotty.

Scotty was discovered in 1991 when an expedition of paleontologists to the Frenchman River Valley in Saskatchewan found a heavy worn tooth and vertebra from the tail of a T. rex, according to the museum.
How did Sue the T Rex die?
The ailment the scientists propose felled Sue and other T. rexes is trichomonosis, also known as trichomoniasis. In birds, the disease is caused by Trichomonas gallinae, a single-celled protozoan. “It’s ironic to think that an animal as mighty as ‘Sue’ probably died as a result of a parasitic infection.

More than 50 specimens of Tyrannosaurus rex have been identified, some of which are nearly complete skeletons. Soft tissue and proteins have been reported in at least one of these specimens.
Where was Scotty the T rex found?
The T.rex Discovery Centre is a museum located in Eastend, Saskatchewan, Canada, that was built to contain the fossil remains of the Tyrannosaurus rex nicknamed “Scotty” which was found nearby. It also showcases many other fossil specimens that can be found in Saskatchewan and the surrounding area.
What caused the dinosaurs to extinct?
As originally proposed in 1980 by a team of scientists led by Luis Alvarez and his son Walter Alvarez, it is now generally thought that the K–Pg extinction was caused by the impact of a massive comet or asteroid 10 to 15 km (6 to 9 mi) wide, 66 million years ago, which devastated the global environment, mainly through

Chelyabinsk meteor. The Chelyabinsk meteor was a superbolide that entered Earth’s atmosphere over Russia on 15 February 2013 at about 09:20 YEKT (03:20 UTC). It was caused by an approximately 20 m (66 ft) near-Earth asteroid with a speed of 19.16 ± 0.15 kilometres per second (60,000–69,000 km/h or 40,000–42,900 mph).
How old is the earth?
4.543 billion years
What is the oldest planet?
It is also the first planet found in a globular cluster. The planet is one of the oldest known extrasolar planets, believed to be about 12.7 billion years old.
How old is the earth right now?
4.543 billion years
How long will the earth last?
By that point, all life on the Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
Who named Chicago?
The name “Chicago” is derived from a French rendering of the Native American word shikaakwa, known to botanists as Allium tricoccum, from the Miami-Illinois language. The first known reference to the site of the current city of Chicago as “Checagou” was by Robert de LaSalle around 1679 in a memoir.
What did Sue Hendrickson discover?
Hendrickson is best known for her discovery of the remains of a Tyrannosaurus rex in South Dakota on August 12, 1990. Her discovery was the largest specimen of a T. rex found and one of the most complete skeletons. This skeleton is now known as “Sue” in honor of her discovery.
How many dinosaur fossils are there?
Dinosaurs have always been an extremely varied group of animals; according to a 2006 study, over 500 non-avian dinosaur genera have been identified with certainty so far, and the total number of genera preserved in the fossil record has been estimated at around 1850, nearly 75% of which remain to be discovered.
What is older than a fossil?
Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old.
What is the oldest human fossil ever found?
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
How did life evolve on Earth?
The evolutionary history of life on Earth traces the processes by which living and fossil organisms evolved, from the earliest emergence of life to the present. Earth formed about 4.5 billion years (Ga) ago and evidence suggests life emerged prior to 3.7 Ga.
Are Velociraptors real?
In real life, however, Velociraptor was roughly the size of a turkey, considerably smaller than the approximately 2 m (7 ft) tall and 80 kg (180 lb) reptiles seen in the films (which were based on members of the related genus Deinonychus).

At 9 meters (30 ft), it was the longest species of Stegosaurus. Stegosaurus stenops: Named by Marsh in 1887, it was discovered near Cañon City, Colorado, in 1886. This is the best known species of Stegosaurus, mainly because its fossils make at least one complete skeleton.
In what year was the fossil found?
Neanderthal fossils were discovered in 1856, but at the time it was not clear that they represented a different species from modern humans.
Is the universe expanding faster than the speed of light?
Although light and objects within spacetime cannot travel faster than the speed of light, this limitation does not restrict the metric itself. To an observer it appears that space is expanding and all but the nearest galaxies are receding into the distance.
When did humans first appear on Earth?
They first appeared in the fossil record around 66 million years ago, soon after the Cretaceous–Paleogene extinction event that eliminated about three-quarters of plant and animal species on Earth, including most dinosaurs.
When did humans appear?
The earliest fossils of anatomically modern humans are from the Middle Paleolithic, about 200,000 years ago such as the Omo remains of Ethiopia; later fossils from Es Skhul cave in Israel and Southern Europe begin around 90,000 years ago (0.09 million years ago).
Where is the meteor that killed the dinosaurs?
Its center is located near the town of Chicxulub, after which the crater is named. It was formed by a large asteroid or comet about 11 to 81 kilometres (6.8 to 50.3 miles) in diameter, the Chicxulub impactor, striking the Earth.
What event killed the dinosaurs?
The Cretaceous–Tertiary extinction event, now called the Cretaceous–Palaeogene extinction event, was about 66 million years ago. It may be called the K/T extinction event or K/Pg event for short. This is the famous event which killed the dinosaurs at the end of the Cretaceous period.
How big was the KT asteroid?
The Chicxulub impactor (/ˈtʃiːkʃəluːb/ CHEEK-shə-loob), also known as the K/Pg impactor and (more speculatively) as the Chicxulub asteroid, was an asteroid or other celestial body some 11 to 81 kilometres (7 to 50 mi) in diameter and having a mass between 1.0 x 10^15 and 4.6 x 10^17 kilograms, which struck the Earth at
When was the last big meteor to hit Earth?

Will Halley’s comet ever hit Earth?
The next predicted perihelion of Halley’s Comet is 28 July 2061, when it is expected to be better positioned for observation than during the 1985–1986 apparition, as it will be on the same side of the Sun as Earth.
