According to the ICS timescale, time divisions are as follows: Age (1 million years, 1000 Millennia). Epoch (10 million years, 10 Ages). Era (100 million years, 10 Epochs). Eon (500 million years, 5 Eras. But, the ICS timescale does not use lustrum, decades, centuries or millennia. Calendar subdivisions use them and according to it, nothing follows millennium. Anything longer than 1 millennium is just referred to as Millennia (Plural form of Millennium).
1.5 million light-years is equivalent to the distance that light travels in 1.5 million years.
160,000 million million.
The basic premise is that the Andromeda Galaxy is 2.5 million light years away, so light from it takes 2.5 million years to reach it. Therefore we see it not as it is now but as it was 2.5 million years ago. The idea that it might no longer exist is rather absurd. A few million years may seem long to us but it is a very short time in terms of how galaxies evolve. It is in all likelihood impossible for a galaxy to experience any significant change in such a relatively short period of time.

10 million years ago they were formed, 5 million years ago, the earth's plates moved to make the mountains higher
Dinosaurs - about 150 million years. Humans - about 1 million years.
Dinosaurs existed from 231 million years ago to 65.5 million years ago, a time span of 166 million years. Humans as a genus have only been around for 2.3 million years, and modern humans for only 200,000 years. So dinosaurs existed for a much longer time than we have so far.

Yes, but for longer than 255 million years. The earliest amphibians evolved in the Devonian Period about 370 million years ago.

The Paleozoic Era was about 2.5 times longer than the Mesozoic Era. The Paleozoic Era lasted from about 541 million years ago to 252 million years ago, while the Mesozoic Era lasted from about 252 million years ago to 66 million years ago.
No 2 years is longer, I think
well it took about 103 years by the construction and athorites
10 million years
Pangea began to drift apart about 200 million years ago. Pangea split into two smaller continents: Gondwana and Laurasia. These continents lasted from about 200 million years ago to 100 million years ago.
