The dinosaurs survived the natural disaster at the end of the Triassic period and went on to dominate the Jurassic period (208 to 146 million years ago).
What era did dinosaurs dominate?
The Mesozoic Era is the age of dinosaurs. These animals grew so large they dominated the planet. Dinosaurs were so dominant that it took a catastrophic, environment-changing event for mammals to be able to take over.
Which period had the most dinosaurs?
Q: Which time period had the most dinosaurs? A: Most dinosaurs we know come from the end of the Cretaceous period. But dinosaurs probably lived in great numbers in all three periods of dinosaur time: Jurassic, Triassic, and Cretaceous.
Which era was the golden age of dinosaurs?
The Jurassic Period was a golden time for dinosaurs, which flourished for 180 million years.
What was the first era of dinosaurs?
First Dinosaurs. Approximately 230 million years ago, during the Triassic Period, the dinosaurs appeared, evolved from the reptiles. Plateosaurus was one of the first large plant-eating dinosaurs, a relative of the much larger sauropods. It grew to about 9 meters in length.
Did dinosaurs live on Pangea?
Dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.
What was a dinosaurs lifespan?
Early estimates of 300-year lifespans for the largest sauropods were based on comparisons with crocodiles and turtles, which have much slower metabolisms. The consensus is now that Apatosaurus and Diplodocus dinosaurs probably only lived for 70 or 80 years, which is about the same as an elephant today.
When did last dinosaurs die?
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.

What came after dinosaurs?
The good old days. About 60 million years ago, after ocean dinosaurs went extinct, the sea was a much safer place. Marine reptiles no longer dominated, so there was lots of food around, and birds like penguins had room to evolve and grow. Eventually, penguins morphed into tall, waddling predators.
What were the last dinosaurs?
The fossil that has been found in a phosphate mine in northern Morocco is of the last living African dinosaurs called Chenanisaurus barbaricus. The Chenanisaurus barbaricus species is said to be one of the last ones to have survived on Earth before an asteroid strike wiped them all out about 66 million years ago.
