Dinosaurs have been extinct for approximately 65 million years. Humans shared a common ancestor with monkeys about 6 million years ago, however Humans as such have only been around for roughly 40 thousand years.
There are over 1,000 species from 500 genera of extinct, non avian dinosaurs that have been found, which is estimated to only be a tiny fraction of the species that did exist. However, birds are considered dinosaurs. Today, there are over 10,000 species of birds that have been discovered.
Birds evolved from dinosaurs that lost their teeth as they adapted to a herbivorous or omnivorous diet. Over time, their beaks became specialized for feeding on seeds, fruits, and insects, eliminating the need for teeth. This evolutionary change allowed birds to become more efficient and successful in their ecological niche.
Cyanobacteria. Cyanobacteria are among the earliest forms of life and are thought to have evolved approximately 2.5 billion years ago. These bacteria are thought to have changed the atmosphere of the planet via nitrogen fixation. The first dinosaurs evolved approximately 250 million years ago during the late Triassic.
No, Even though it hasn't erupted in over 1,400 years it is not considered extinct
Mammals .
Dinosaurs lived in the Jurassic Period over 145 to 200 million years ago. Dinosaurs became extinct during the Triassic period.
you don't because you weren't born yet but scientists say over a million years ago
Yes, all dinosaurs are extinct. They all went extinct millions of years ago. The exact cause of why they all went extinct is debated by scientist and anthropologist.
Dinosaurs became extinct at the end of the Cretaceous period that is almost 65 million years ago. Genus Homo evolved about 2.5 million years ago. On the other hand, we've changed the name of dinosaurs over the years; now they are called birds.
Dinosaurs used to live everywhere, they were all over the earth
They lasted for over 160 million years until they became extinct as a result of the Earth being struck by a meteor about 65 million years ago..
Not all the dinosaurs were huge, indeed some were very small. They and their reptilian ancestors lived over a period of more than two hundred million years. The last dinosaurs became extinct around 65 million years ago.
We are living in a warm period of an Ice Age now, called an interglacial period. Dinosaurs became extinct over 65 million years ago but there have been many Ice Ages since they died out. There may even have been Ice Ages during the time of the Dinosaurs.
It has to do with the food chain. Say if T-Rex are extinct, the animals it eats over-populate and take all the food or water. Slowly, all the animals start to become extinct. Or, if a certain animal becomes extinct, the things it eats over-populate and the things that eat it normally become extinct.
All over. No continent or major island that didn't have its dinosaurs. Of course, for most of the "age of the dinosaurs" the continents were joined, so it was possible to walk just about everywhere.
A:No. The last dinosaurs became extinct around 65 million years ago. On the other hand, the Bible was written over a period of several hundred years, around two thousand years ago. Not only is the Bible of quite recent origin, its authors had no concept of dinosaurs and therefor did not mention them.
