How did a Stegosaurus get extinct?
Scientists think this was probably because of an asteroid that hit the Earth. The asteroid impact would have made a big change to the Earth’s climate and vegetation. Unfortunately, the dinosaurs couldn’t adapt to the change of climate and food available after the collision and became extinct.
How long did it take for Dinos to become extinct?
65.5 million years ago
Dinosaurs roamed the earth for 160 million years until their sudden demise some 65.5 million years ago, in an event now known as the Cretaceous-Tertiary, or K-T, extinction event.
When was the last Stegosaurus alive?
Stegosaurus was a large, plant-eating dinosaur that lived during the late Jurassic Period, about 150.8 million to 155.7 million years ago, primarily in western North America.
Which dinosaurs didn’t exist together?
The truth is, dinosaurs roamed the Earth for a long time, and they all most certainly did not exist together. For example, the Stegosaurus roamed the Earth during the late Jurassic period, between 156 and 144 million years ago.
When was the last time a Stegosaurus lived?
Stegosaurus is a genus of extinct, armored stegosaurid dinosaur that lived 155 – 150 million years ago. Remains of 80 individuals have been unearthed from the upper Morrison Formation in the western United States.
How long did it take for the dinosaurs to go extinct?
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
Why was the Stegosaurus an herbivorous dinosaur?
It is believed that herbivorous dinosaurs had beaks, but lacked strong jaws and teeth for grinding. The stegosaurus had swollen cheeks that enabled it to feed a lot and store a surplus food for future use. This is why it was able to store food in the body for longer than any other dinosaur.
How did the Stegosaurus ungulates get its name?
In 1879, Stegosaurus ungulates (meaning ‘hoofed roof lizard’) was named by Marsh from fossil samples unearthed at Como Bluff, Wyoming. It has been suggested that it could be synonymous with S. armatus. In 1887, Marsh described Stegosaurus sulcatus (meaning ‘furrowed roof lizard’).
