This May Be A Dumb Question But what made the dinosaurs grow so big?

Natural selection.  Since competition was low, and food was so abundant...the bigger the better.  Also, if you were bigger you could kill smaller things or defend yourself from something that wanted to eat you.  Mammals were favored to remain small during that time because competition would have been too high with all the huge dinosaurs around.  After they died out, mammals had a free world to investigate, and some of them got very large as a result. (Mammoth, Mastadon, Rhinocerous, Giant Ground Sloth, etc.)  It's all about evolution.

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

They can't, actually, not without mixing it with another creature. Because all cells come from cells. You'd have to put the dino DNA into a modern reptile cell. And it does matter, because it is cellular machinery that brings about gene expression - and that can have a huge effect on gene expression. (epigenetic inheritance) So you would not really know what trait was dinosaur, and what was artifact from expressing the genes in a modern reptile cell. \n\nStill and all, it would be fun, I agree!

your question sounds less like a question and more like a rant against the people you're asking to answer it. I suppose it is crazy to think that God created dinosaurs as well as the rest of the world.  I mean, if I'm brave enough to believe God made an entire universe out of nothing, why are dinosaurs so hard to add to the equation?  \nand there are Christians who believe in the day age theory, or theistic evolution. Ancient Hebrew, which the creation story was written in, is very poetic, and can be difficult to translate exactly/literally. So when they refer to days, some scholars say a day could refer to any period of time, such as an age, one thousand years, etc.  \nand Christians aren't the only ones capable of being narrowminded. you don't sound like you accept other peoples' right to believe something different than you and still be intelligent humans. that's called hypocrisy.  I'm christian, and I respect your ability to believe something different, even if I think you're wrong. and I don't immediate assume you're stupid for doing so.  so I guess you're in the same club as the ones you criticize.

the earth was at a stable orbit.  no  tilt or axis to cause differences in the seasons the earths temperature was just about uniform at 72 deg F.  the earth was at that tome also protected by the vapor barrier basically A thin shield of ice in the uper atmosphere that served 2 purposes it blocked out the harmful ultra violet radiation from the sun  and it increased the atmosphereic pressure to 2 atmospheres.\n\nthis caused things to live a lot longer and grow a lot bigger.  plants for one thing.  there is more coal on the earth right now then there are plants to produce it.  meaning if you were to take all the plants on earth right now and turn them into coal the pile of coal that you could make would be less than that currently available in the ground not including what has already been taken out.\n\nplanys grew much taller in this environment and so did reptiles lets take the crocodile.  a croc now a days can live about 100 years.  reptiles throughout thier life never stop growing.  so now you have an animal that in 100 years can grow to be about 15 feet long but instead you give it 900 years to grow.....presto you have a dinosaur.  \nthen a few thousand years ago an ice meteor crashed through the vapor barrier hitting the earth. this caused the barier to colapse and as it fell it began to melt and other various things and the world was covered in a great flood.  the earth finally settled back out into a somewhat normal rotation (you ever seen what happens to a gyroscope when you bump it)\n\nnow the earth has a 27.3? or is it 23.7 deg tilt to its rotation that causes us to have 4 seasons and tropics temperate zones and artic zones.\n\nBTW the earth is between 6000 and 10000 years old SCIENCE CAN PROVE IT.  if you want to know how just ask me.  i'll try to explane it as best as i can or you can wisit this website.  and do some reading\n\nall the SCIENCE is right there.

i personally feel the meteor impact was the cause of the KT extinction - but people should not infer that the impact itself killed everything off - it was the fallout from the impact (the extremely versatile climate) which led to the dinosaurs being unable to adapt to it and dying off

carchardontosaurus, it was about twice the size of the average t-rex.  You can stand up inside its mouth.  you cant do that in a t-rex.

Silly old scientists did...they placed false chicken bones that have been pumped up in size to appear huge and then buried in the ground to make fools of creationist's...we are onto them though!

When did God create dinosaurs, and when did they become extinct?\n\nThe Bible does not provide specific answers to this question. According to the Genesis account, animals were created during the fifth and sixth creative periods or ‘days.’ If the Hebrew expression translated “great sea monsters” [Hebrew, tan·ni·nim'] includes dinosaurs, which often inhabited swampy, watery areas, this would mean that dinosaurs were created on the fifth “day.” (Gen. 1:21) We do not know whether they continued to exist until man was created (toward the close of the sixth “day”). At the very latest it seems likely that they must have disappeared off the earth at the time of the flood of Noah’s day. Dinosaurs were reptiles, and some kinds of dinosaurs bear strong resemblance structurally and otherwise to lizards (sauros is, in fact, the Greek word for “lizard”; saura in Leviticus 11:29 . Not all types of dinosaurs were of such gigantic size. Hence, even if they had survived till the Flood, this would not have required taking pairs of the mammoth varieties into the ark. Other smaller members of the particular family or “kind” to which these belonged would have sufficed to fulfill the divine command.\n\nWhile the radioactive dating method is innovative, it is still based on speculation and assumption. In contrast, the Bible account in the first chapter of Genesis simply states the general order of creation. It allows for possibly thousands of millions of years for the formation of the earth and many millenniums in six creative eras, or “days,” to prepare the earth for human habitation.\n\nSome dinosaurs (and pterosaurs) may indeed have been created in the fifth era listed in Genesis, when the Bible says that God made “flying creatures” and “great sea monsters.” Perhaps other types of dinosaurs were created in the sixth epoch. The vast array of dinosaurs with their huge appetites would have been appropriate considering the abundant vegetation that evidently existed in their time.—Genesis 1:20-24.\n\nWhen the dinosaurs had fulfilled their purpose, God ended their life. But the Bible is silent on how he did that or when. We can be sure that dinosaurs were created by Jehovah for a purpose, even if we do not fully understand that purpose at this time. They were no mistake, no product of evolution. That they suddenly appear in the fossil record unconnected to any fossil ancestors, and also disappear without leaving connecting fossil links, is evidence against the view that such animals gradually evolved over millions of years of time. Thus, the fossil record does not support the evolution theory. Instead, it harmonizes with the Bible’s view of creative acts of God.\n\nWhen Did They Live?\n\nDinosaurs played a dominant role in life on earth during their age. But then they came to an end. The rock layers containing human fossils consistently occur above those layers containing dinosaur fossils. Because of this, scientists generally conclude that humans came on the earthly scene later.\n\nIn this regard the book Palaeontology, by James Scott, states: “Even the earliest species of Homo sapiens (man) lived long after the disappearance of the dinosaurs . . . After tilting (through earth movement) has been allowed for, rocks containing fossil men consistently occur above those preserving the bones of the great dinosaur reptiles and it follows that the latter belong to an earlier age than the human remains.”

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.

Yes, that's definitely why dinosaurs were so big -- another moon pulling on them! Why haven't all these smart scientists thought of such an obvious answer? And I'll bet that second moon crashed into the earth and killed all the dinosaurs too.

they called them dragons in the bible silly.\n\nand there is more proof of dinosaurs than there is of God

The stegosaurus, the one with the spikes running up and down its back. Archaeologists found there was a big enlargement in the stegosaurus's spinal cord at the point where it passed through the pelvis. Since the stegosaurus had a pretty poor excuse for a brain in its head--the thing was about the size of a walnut, only 1/20th the size of the mysterious butt organ--speculation arose that the giant reptile needed some auxiliary gray matter to mind its rump while the forward brain handled business up front. Alas, Later scholars decided that the putative afterbrain was just a neural junction where a lot of nerves happened to enter the spinal cord. Such junctions are found in many lizards, as well as in the ostrich. \n\nSo, the answer is no.

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.

sure they were, this is clear because of the evidence we've got from geology. the bones we've found don't lie. but something you should notice, and that is dinosaurs were not all huge wild animals, they were just a kind of animals, including all sizes and all behaviours. also it is believed that some of the animals living nowadays are the children of ancient dinasaurs.

The largest carnivorous dinosaus was the Spinosaurus aegypticus (remember the one with sails on its back in Jurassic Park III?). It is estimated to have been 16-18 metres long and 6 metres tall at the hips and would've probably weighed somewhere around 9 tons.\n\nRecently, a theropod dinosaur larger than t-rex was discovered, though it wasn't as big as Spinosaurus.\n\nThe largest confirmed dinosaur of all times is a sauropod named Supersaurus(about 35 metres long) though there are reports that a species of sauropd - Amphicoelias is longer than fifty metres.
