Previous answer: We Were All Monkeys.
This previous statement is about as wrong as you can get without believing in magical invisible friends.
Monkeys are many millions of years away and human (and monkey) ancestors, at this point, can best be described as ratlike.
It would be the late Jurassic period, specifically the Oxfordian stage. Dinosaurs are absolutely the dominant life form on the planet with the massive sauropods dominating (although mighty brachiosaurus was gone for some 6-7 million years by this point). The first birds and saurians (crocs, gators) also appear around this time
The supercontinent Gondwana continued its westward migration, having started some 20-25 million years previous to the requested year
It was actually a relativel peaceful time, as the last major extinction was 20-25 million years previous and the next would be in another 15 million years
That is the Precambrian era, when the earth and moon formed. the continents were merging together to form super-continents, and simple single cellular organisms began the first life on the planet,
Now, we do know a great deal thanks to the fossil record
It was the Calabrian stage of the Pleistocene. 1,000,000 years is not particularly significant - the end of that stage had the poles reverse and a plunge into an ice age
Animals would be largely familiar, including mastodons, smilodons and giant sloths. Not to mention Homo erectus, one of our more successful ancestors.
Earth was in the Lutetian stage of the Eocene epoch of the Paleogene Period. See link.
In about 204 million years ago, an asteroid hit earth causing a mass extinction. It was the end of the Triassic Period and the beginning of the Jurassic Period.

Placental mammals give birth to live young, and they descended from a common ancestor scientists simply call the "boreoeutherian ancestor." The creature scurried about the woodlands of Asia more than 70 million years ago.
6 in dog years and 42 in human years
Pronghorns can hit 55 mph for about a half a mile, then they slow down a bit: 42 mph for one mile, and 35 mph for 4 miles. Up until the extinction of the American Cheetah 11,000 years ago, they had to run that fast to survive. The extant Gray Wolves and Mountain Lions have a hard time preying upon them.
one year for a human is seven years for a dog..... human years ~dog years 1~7 2~14 3~21 4~28 5~35 6~42 7~49 8~56 9~63 10~70 and so on.
"Cat years" is an expression that compares the age of a cat to the age of a human. Because each is a different size and has a different lifespan, we use the approximate ratio of elapsed time to expected time. Say that a cat lives for 10 years and a human lives for 70. When the cat reaches age 6, it is at the equivalent point in its life to a person aged 42. So in 'cat years' the cat is aged 42, while in real time it is only 6. The same idea can be applied to other animals, dogs being the main one.
Approximately 42 million years ago.
It became extinct 1.5 million years ago, but it would have lived as long as any other shark probably. SuperSlasher
42 years ago
no, saber toothed tigers lived during the ice age - with mammoths and stuff, way before the dinosaurs No, the Stegosaurus went extinct at the end of the Jurassic Period, around 150-145 million years ago. The first sabre-toothed cat appeared 42 million years ago. The Ice Ages happened after the extinction of the non-avian dinosaurs.
42 years ago
The Silurian went from 443.4 ± 1.5mya to 419.2 ± 3.2mya. It spanned from the conclusion of the Ordovician period to the beginning of the Devonian period. However the exact time frame of the Silurian period is unknown and could be off by millions of years because of the fact that that period was set during a significant extinction event. Therefore, the Silurian period lasted about 42 million years, give or take.
It was created about 1770 BC in Babylonia.
She died 42 years ago.
There was more than one volcano there, active between 42 and 17 million years ago. They are all now extinct and part of the geologic sequence.
Answering with the current year (2014) as of this answer: 1972. All you have to do is subtract 2014 and 42, which gives you 1972.
(42mya-11,000 years ago), existing for approximately 42
