How did T Rex go extinct?
T. rex went extinct during the K-T mass extinction, about 65 million years ago. This extinction was probably caused by a catastrophic asteroid colliding with Earth. It is thought that a an asteroid 4-9 miles (6-15 km) in diameter hit the Earth off the coast of Mexico.
What is the largest sea creature to ever exist?
How long did it take for the dinosaurs to die after the asteroid?
Scientists have also found very few continuous beds of fossil-bearing rock that cover a time range from several million years before the K–Pg extinction to a few million years after it. The sedimentation rate and thickness of K–Pg clay from three sites suggest rapid extinction, perhaps less than 10,000 years.

Did all dinosaurs live at the same time?
Dinosaur communities were separated by both time and geography. The ‘Age of Dinosaurs’ (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Many dinosaur types were spread across it.
Are there any living dinosaurs today?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
How did every single dinosaur die?
Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth’s climate that happened over millions of years.

What’s bigger than a blue whale?
While there might never be a larger animal than the blue whale, there are other kinds of organism that dwarf it. The largest of them all, dubbed the “humongous fungus”, is a honey mushroom (Armillaria ostoyae).
