When did dinosaurs first exist?

A LONG time before Jesus. \n\nDinosaurs are believed to have evolved during the Triassic period, which is 250-200 million years ago.\n\nDinosaurs evolved from a group of reptiles called Archosaurs. The Archosaur line split, in the middle to late Triassic period. One portion evolved into Crocodiles... the other part gave rise to the dinosaurs, and through dinosaurs to birds. \n\nBy the late triassic (228 million years ago - 200 million years ago) several theropod carnivorous dinosaurs had evolved, such as Eoraptor, Coelophysis and Herrerasaurus - the ancestors of later giants such as T.rex.  At this time dinosaurs such as plateosaurus had evolved too - the ancestors of the later giant herbivorous dinosaurs such as diplodocus and brachiosaurus. \n \nThe dinosaurs eventually became extinct 65 million years ago.

The sudden mass extinction of the non-avian dinosaurs, which occurred around 65 million years ago, is one of the most intriguing mysteries in paleontology. Many other groups of animals also became extinct at this time, including ammonites (nautilus-like mollusks), mosasaurs, plesiosaurs, pterosaurs, herbivorous turtles and crocodiles, most birds, and many groups of mammals.[32] The nature of the event that caused this mass extinction has been extensively studied since the 1970s. At present, several related theories are broadly supported by paleontologists.\n\nThese were some of the causes for their extinction as well:-\n\nAsteroid collision\nMultiple collisions—the Oort cloud\nEnvironment changes\n\nFor more information go through the link below.

Some people, I swear, are not qualified to answer here. \nThere is a 65 million year gap between the cenozoic and mesozoic eras.  Hominins, or human ancestry, began in the cenozoic while dinosaurs rose, and fell, in the earlier mesozoic.  Also rising in the mesozoic were early mammals...long before any humans.  Most of these were mouse-shaped.  Look in any biology textbook and you can find these general concepts.  Also check out your local museums.

No one knows if dinosaurs existed, what we know is that fossils of dinosaur bones exist.  The sensible explanation is that dinosaurs did exist and their bones became fossils, but why do you care about what is sensible?  According to the bible the earth was created in 6 days, that is wrong to.  The only time the bible is right is by accident.  Snakes use to talk in the bible.  You have to admit the bible leaves a lot out.  Like if Adam and Eve had 2 sons, and no daughters, where did Cain and Abel's wives come from?

Why did all of the remaining dinosaurs die out suddenly at the end of the Cretaceous period? There is a short answer and a long answer to this question.\n \n2     Here is the short answer. No one knows for sure.\n \n3     Here is the long answer. There are a number of theories. Some are scientific, and some are ridiculous. Most scientists believe in one or two main ones, but no one knows for sure.\n \n4     The reason no one knows for sure is because the whole thing happened about 65 million years ago. No one was around to see or hear what was going on back then, and no one was around to keep records.\n \n5     What we do know comes mainly from fossil records. Scientists study the fossils themselves, and they study the rock in which the fossils are found. Fossil records haven't given us definite proof for any one theory. This is because there are some problems with fossil records. For one thing, most fossil evidence of dinosaurs has been found in North America. We don't know as much about dinosaur activity on other parts of the earth. Another problem is that it is very hard to date fossils. Dating fossils means determining how old they are.\n \n6     One really interesting thing about the big dinosaur question is that scientists from many different fields are working to solve the problem. Astronomers, physicists, geologists, paleontologists, ecologists, chemists, geologists and others are all gathering evidence, experimenting, and researching to try to solve the puzzle.\n \n7     The most popular theory is called the Alvarez Hypothesis. This hypothesis says that, 65 million years ago, a big asteroid hit the earth. This asteroid crash scattered dust high up into the atmosphere. It blocked much of the sunlight and caused the earth to become cooler. The crash also started huge fires, high winds, and violent storms that killed some of the dinosaurs. The lack of sunlight and warmth caused many plants to die. This shortage of plants for food caused the rest of the dinosaurs to die out.\n \n8     The second most popular theory says that activity on the earth itself caused the extinction. As the supercontinent of Pangaea was breaking up, movement of the earth's giant land plates caused volcanoes to erupt and the climate to change. These changes affected the earth's atmosphere and temperature, and the dinosaurs died out from the cold or from lack of plants to eat.\n \n9     Other theories suggest that dinosaurs became so big that they couldn't move, or that there were too many dinosaurs and they ate up all of the food.

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

Dinosaurs are never mentioned explicitly in the Bible, if at all. I have already seen you have been pointed to Job for Leviathan and Behemoth. That's the only potential mention in the Bible of dinosaurs.\n\nI see the creation story at the beginning of Genesis as a very quick overview - not a scientific textbook on how God made the world, but more of an overview to say "God made the universe, then he made man, then man screwed up and let's pick up with these people here." So, to me, the beginning stories - the creation and fall - are there as a quick introduction that sets the tone and the themes for, really, the entire rest of the Bible.

Geologic time goes back millions, if not billions of years. For example, dinosaurs first appeared on earth between 200 and 240 million years ago, in a time period known as the Triassic. They lived through the Jurrassic until the Cretaceous (65 million years ago) periods. \nIn short geologic time is a time scale that has been put together based on fossil and other evidence to depict the earths past from formation (4.5 billion years ago) to present time.

according to the geographic history. we have lots of dinosaurs laying eggs on earth even before the chickens arrive and laye their own eggs. therefore eggs come first before chickens.. hehehe...

Since dinosaurs are believed to be reptiles and birds, then yes, all would have been hatched from eggs.

Yes, in China I believe.\n\nDo remember, though, that the difference between a dragon and a dinosaur may essentially be nil (although my nephew knows that a dinosaur has its hands included in its wings, but a dragon has wings AND arms!).  \n\nI sincerely doubt that the fossil they found was an animal that breathed fire.

Humans came a long time after dinosaurs, Apart from the Flintstones. and if you wanna know what your ancestors looked like , ME

For hundred of years, bones were found in China, labelled "dragon bones" ground to a poweder and used as folk remedies. Discovering a dinosaur bone was not hard, identifying such bones as being from a disappeared animal required a bit more imagination, running against the "teaching" of religious beliefs.\nThe first full dinosaur skeleton discovered which was recognized as such, occured in 1858, 148 years ago (see link).\n\nAs to the number of dinosaur spieces, it must have been nearly one million.  There are 5500 species of mammals alive today, and most of them are less than one million year old (the ancestor of those mammals living today disappared, along with some speices that dies off without leaving descendants). If one assumes that dinosaurs occupied essentially all the ecological niche that mamallians do today (there were tiny dinosaurs the size of mouse, no all dinosaurs were huge) and given that dinosaurs lived and ruled the Earth from 230 million years ago until 65 million years ago (so 165 million years), and assuming that a speice lasts one million years, that is about one million indeed.\nWe will never find them all, many dinosaurs may have disappered without leaving traces that we will ever find.

Dinosaurs were here before Adam and Eve. The bible didn't focus on the creation of the earth. Genesis focused mainly on the creation, rise, and fall of man.

Where does it mention dinosaurs in the Bible?

No, the Earth is much much older.  This is why the Bible is not to be taken literally.  If anything, we were meant to eventually point out these inconsistencies.  The truth is that the dinosaurs existed a long time ago (dragons) and were created to be just another amazing addition to life here on Earth.\n\nThe dinosaurs existed at a time when gravity as we experience it now was attenuated, and we experience much muss less of it.  This is how dinosaurs like the ultrasaur and massive bids like the teratorn were able to walk and fly around without collapsing under their own weight.
