Answer 1

Excuse me, I am still very much alive and kicking (and munching and crunching)

Answer 2

The oldest dinosaur types are known from rocks in Argentina and Brazil and are about 230 million years old.After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. The largest complete dinosaur we know of was Brachiosaurus ("arm lizard"); it reached 23 m in length and 12 m in height (about the length of two large school buses and the height of a four-story building).Mussaurus ("mouse lizard") was claimed as the smallest dinosaurDinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years. There is now widespread evidence that a meteorite impact was at least the partial cause for this extinction...

Answer 3

Thedinosaurs lived during the Mesozoic Era, from late in the Triassic period (about 225 million years ago). Most of the better known species of dinosaurs are said to have appeared in the Jurassic period, approximately 200 million years ago.The dinosaurs flourished through the Cretaceous period, becoming extinct over 60 million years ago.Their reason for their sudden erxtinction is still unknown. But there are several assumptions as to thier extinction without any proof.

Answer 4

The dinosaurs became extinct at least 62 million years ago, but they existed for 100 million years before that.

Answer 5

First Dinosaurs came in the TRIASSIC PERIOD -- 250 to 205 million years ago. Bony fish also came in this period.
In the Jurassic period came Large dinosaurs. First mammals and birds too came into existence in this period --205 million years to 140 million years.
Dinosaurs lived till this period and died.

Answer 6

the dinosaurs went extinct about 65 million years ago when a meteor hit the earth which resulted in dust and other particles to settle in the earth's atmosphere.as a result sunlight could not reach the earth's surface resulting in ashyphixtion or choking of oxygen from entering the body which is needed to keep us alive.........they were in evolution for about 200 million years before that.....

Answer 7

Dinosaurs first walked the earth about 224 million years ago and died out about 65 million years ago.

It's not usual to use centuries for years as long ago as that, but if you want to, these correspond to the 2,240,000th Century BC and the 650,000th Century BC.

Answer 8

dinosaurs originated about 250 million years ago n became extinct around 60 million years ago ....

Answer 9

listen, when dinos used to rule thge earth, there were no humans.then HOW CAN THEY HAVE MADE A CALENDAR TO COUNT CENTURIES?????
