From 225 to 65 million years ago
225 million - 65 million = 160 million BC
So that means dinosaurs have been on the earth for 160 million years.
They Have Been Around Since The Dinosaurs Were Living
A very long time
Not dinosaurs as we traditionally think of them. "Classic" dinosaurs went extinict long before any people were around. However, scientists now know that one group of dinosaurs lives to this day: birds. Birds of various types have long been hunted by humans.
Dinosaurs have long been extinct, making it impossible for scientists to work with living dinosaurs.
Yes. Mosses were around long before the dinosaurs were.
they have been around since the dinosaurs.
earthworms were the third form of life. They have been around for over 2000 years.
None - dinosaurs are extinct, and have been for a very long time.
since dinosaurs...
350 million years
Excluding birds (a subgroup of dinosaurs), they lived for 166 million years, which is a long time for an animal group. Including birds, they have been around for 231.4 million years so far, and will probably continue to exist as long as there is vertebrate life on land.
because humans were not around at the time but if they were they would have been dead because of all the carniverous dinosaurs
