490 million years ago.
the baroque period started in 17th century. around 1600 to 1750.
The Triassic period started 252.2 million years ago and ended 201.3 million years ago. It was the first period of the Mesozoic era.
well, if your saying that you never had your period before and then you started, and then two years later you started again...............then it does not mean anything. that's actually normal,so you have nothing to worry about, I wondered the same thing when that happened to me.=)

You mean if she has never had a period? Pregnancy would be unlikely, but not totally impossible if she were about to have her first period. Don't forget that sex under 16 years is illegal in most countries. Some have a higher limit.
its just irregular, this is normal for the first years, up to 3 or even 4 years until your period cycle will become normal.
The end of the last glacial period is the start of the Holocene epoch.
Dinosaurs have been alive in the Mesozoic Era. The Mesozoic Era consist of three time periods the Triassic, Jurassic, and Cretaceous. The Triassic is the oldest part of the Mesozoic Era. The Cretaceous is the youngest part of the Mesozoic Era. The Triassic period had started 227 million years ago and ended 22 million years later. When the Triassic period ended the Jurassic period started. The Jurassic period started 205 million years ago and ended 61 million years later. After the Jurassic period came the Cretaceous period. The Cretaceous period started 144 million years ago and ended 79 million years later. The dinosaurs have been alive ever since the beginning of the Triassic period and are still alive today. But the dinosaurs that are alive to this day are the evolve creatures of those in the past.
It started 1.6 million years ago and is still going on.
