It would have been 149,997,988 years BC (in 2013). But, assuming that 150 million is, at best, accurate to the nearest million years, for all intents and prposes, the answer should be 150 million years BC.
One million is one thousand thousands. Three million is then three thousand thousands.
To calculate how many years ago 1642 was from the current year, you would subtract 1642 from the current year. For example, if the current year is 2022, the calculation would be 2022 - 1642 = 380 years ago. Therefore, 1642 was 380 years ago from the current year.
.3 is the same as three tenths. Three tenths of one million is three hundred thousand years.
60 million seconds, 16666.666(repeating) hours, 694.444(repeating) days, 99.206349 weeks, or 1.907814 years ago.
Year 17990 BC.
Allosaurus fossils date to between 155 and 150 million years ago. Presumably they died out around 150 million years ago.
The youngest known fossils of Apatosaurus date to 150 million years ago. Thus, Apatosaurus probably died out around 150 million years ago.
150 millions years ago Earth was in the late Jurassic period.

No, snakes evolved much later, in the Early Cretaceous epoch, about 150 million years ago.
The lived in North America from 150 million years ago until 66 million years ago. (None live now.)
Apatosaurus fossils date to between 154 and 150 million years ago. After that, they disappear from the fossil record, so it is safe to say they probably died out around 150 million years ago.
Stegosaurus fossils date to between 155 and 150 million years ago. Presumably they died out around 150 million years ago, during the Tithonian stage of the Jurassic period.
Archaeopteryx lived in Europe between 150.8 and 148.5 million years ago. Diplodocus lived in North America between 154 and 150 million years ago. Stegosaurus lived in North America and Europe between 155 and 150 million years ago. Brachiosaurus lived in North America between 154 and 153 million years ago.
Stegosaurus existed from about 155 to 150 million years ago. That was during the Kimmeridgian and Tithonian stages of the Jurassic period. Stegosaurus fossils were discovered in Morrison, Colorado in 1877 by Othniel Charles Marsh.
They lived some 155 to 150 million years ago.
No, Pangaea was the continent that existed when all the current continents were connected. It lasted from about 300 million years ago until about 150 million years ago.
Plants with seeds first evolved 385 million years ago. That was more than 150 million years before dinosaurs evolved 231.4 million years ago.
Allosaurus lived between 155 and 150 million years ago. This was during the Kimmeridgian and Tithonian stages of the Jurassic period.
The compsognathus when extinct about 145 million years ago during the jerassic period
Most Allosaurus would have been killed by predators, other Allosaurus, or in struggles with prey or disease very young. The maximum lifespan of Allosaurus was about 28 years. If you are asking when Allosaurus went extinct, they died out about 150 million years ago.
the first bird to come to earth was about 160 million years ago. this is by faith bradford *by G1N4* to be more precise it was the Mezozoic era and the Jurassic period.
