what is the total amount of time that dinosaurs have been living on the earth?
481521
The first dinosaurs appeared about 230 million years ago, during the Triassic Period.\n\nThe dinosaurs became extinct at the end of the Cretaceous Period,  65 million years ago. \n\nSo the answer is 230-65 = 165 million years. \n\nSome scientists believe that direct decendants of dinosaurs still exist. We call them birds.

The Earth was formed around 4.57 billion (4.57×109)[1] years ago

According to the US Geological Survey (USGS), the Earth is approximately 4.5 billion years old.\n\nThe articles below discuss the evidence for this estimate.

About 4600 million years.

Every 64 million years or so, the earth is hit by gigantic comet and the impact is so tremendous that vast amounts of dust and debris is sent into the atmosphere, blocking out the sun. This causes massive drops in temperature sending the earth into an ice age, wiping out all life on earth. This very same catastrophe wiped out the lifeforms on the planet before the dinosaurs existed, and the lifeforms before those, since this planet has not been hit once, but many times, making this an incredibly ancient planet. Don't know if 64 million years will have passed since the last ice age by 2026 though.

The earth as it was 100 million years ago.\n\nSimple really!

Fools of faith.  I always enjoy asking devout Christians if they believe in dinosaurs.  When they say yes I ask them how long ago they lived.  When they say millions of years ago I ask them how that could be when the Bible says the Earth is only 6000 years old!  It's funny watching them try to squirm their way outta that one.

You need help so I am going to help you alot right here first I am sorry but the person that put the dates on the dinsouar created the 6th day needs to read his text books again and look at his history ok. With that said I going to answer your question and show you all the time line\n\n251 MYA-The Mesozoic Era starts, and the Triassic Period Begins. \n230 MYA- The First Dinosaurs Appear \n200 MYA- The Jurassic Period begins \n145.5 MYA- The Cretaceous Period Begins. \nc. 65.6 MYA- An Asteroid hits the Earth. The Dinosaurs survive, but begin to die out. \n65.5 MYA (DOOMSDAY)- The Earth is hit with a sudden climate change (possibly another Asteroid), This time, the Dinosaurs will NOT survive! \nc. 64 MYA- the Cenozoic era Begins. \nc. 64 - 49 MYA- for the first few million years, The entire Earth is ruled by one Creature; up to 2ft+ tall, and prayed on horses... The Birds: the decendants of the Dinosaurs\nand there was several Ice Ages after that.

It doesn't.  The dinosaurs existed millions of years before mankind. They died off around 65 million years ago.

The official estimate now is 13.7 plus or minus 0.2 billion years old.\n\nBut this continues to be a tricky number to pin down. It depends primarily on the rate of expansion of the universe. Recently it has been found that the rate of expansion is increasing (that is the universe is expanding more today than it it did a billion years ago, and will be expanding faster a billion years into the future).\n\nHaving said that this continuing field of study in cosmology is no consolation for Young Earth Creationists. I mention that because some have a habit of jumping on any disagreement in science as a way to promote their own. The universe is clearly between 10 and 20 or 25 billion years old. Not 6,000 years old.

Dinosaurs are still the most diverse class on the planet, but we call them birds! Pretty cool huh? As an amature paleontologist I can honestly say the no professional paleontologist can honestly that any classic dinosaurs are still around. Another thing about dinos: Dinosaurs were land living animals so no dinos lived in the oceans. Sometimes fossilization is not total and some original bone is still in the fossil and sometimes it appears bleached and to the untrained eye looks fresh. Sorry, but no paleontologist has told me (I am in contact with most of them) that there is a possibility that classic dinosaurs are extant (not extinct) except for their only direct descendents - the class Aves (birds).

Yes, it's going pretty fast! When you think that 150 years ago there were no cars or airplanes. Pretty freaky.\nNothing moved this fast in the past 1,500 years.\nAlso, going off on a tangent a bit... Did you know that 90% of all the extinct creatures that we know about (including all the dinosaurs) have become extinct in the past 150 years!\nMaybe it's all going too fast.

Dinosaurs were created by a Supernatural Diety (a.k.a God) and a lot of them became extinct when the Earth became flooded almost 3000 years ago.\n\nDinsoaurs are NOT extinct; there are placed in Africa, South America, the oceans and lakes where dinosaurs still exist.

Somewhere around 10 million years. This should be compared to the sun, which will last a total of 10 *billion* years.\n\nHomework?

I don't really know which was first, but I would have to guess dinosaurs.  Remember, that one of God's weeks is probably not a week to us.  There are some rules on time in the Bible, and in one scripture (can't remember where it is in the Bible), one day for God is a thousand years for us.
