Where was the largest dinosaur fossil found?
Fossil of ‘first giant’ dinosaur discovered in Argentina. They are the biggest animals to have walked the Earth, with some weighing as much as a space shuttle.

What’s the smallest fossil ever found?
‘Smallest fossil’ scanned by University of Manchester. An X-ray scan of Baltic amber at the University of Manchester has revealed what scientists have said is the “smallest arthropod fossil ever”.

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.

Earliest life forms. Fossil evidence informs most studies of the origin of life. The age of the Earth is about 4.54 billion years; the earliest undisputed evidence of life on Earth dates from at least 3.5 billion years ago. There is evidence that life began much earlier.
How many full dinosaurs have been found?
Currently it is estimated that around 2,100 “good skeletons” have been found, and the number of known species is several hundred (300-500). Therefore, even without an entire skeleton, but with other skeletons from the same species, we have a good chance of completing the full picture.
How many T rex skeletons are there in the world?
More than 50 specimens of Tyrannosaurus rex have been identified, some of which are nearly complete skeletons.
What caused the extinction of dinosaurs?
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
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.
Could a Triceratops kill at Rex?
Evidence of head injuries on Triceratops indicates Tyrannosaurus rex attacked living Triceratops. Using a steel Tyrannosaurus skull, scientists learned that Tyrannosaurus could easily crush a small car. Tyrannosaurus could bite through bone, at a bite force of at least four tons per square inch.
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).
