Did dinasuars grow fast or did they live a long time to grow so big?

For the population density of say, a large sauropod, which were chiefly herbivorous, they would have had to consume extreme amounts of high energy foods to grow fast.  Since plants require a massive metabolism to digest, their metabolism must have been very slow, which in turn means that they grew slowly.  \n\nA carnivore like your garden variety t-rex, which was also very large, would have had a faster metabolism because he ate (supposedly) large quantities of protein, but still, every organism´s metabolism is dictated by the same rules, so t-rexes must have been slow too, thus indicating that they also grew up pretty slow (considering their size of course).

That depends on the species; typically larger forms live longer, but there are many factors that influence longevity.\nHere's a webpage with documented longevity records, look at those for order Primates:\nhttp://www.demogr.mpg.de/longevityrecords/0203.htm

Are you sure it wasn't an insect of some type, like a stick insect or even a dragon fly? They can grow quite large sometimes. Either that or some bast@rd was playing a sick joke on you.....!\n\nsee the site below - there are some HUGE stick insects on there!!

From what I understand and it has been proven scientifically. There use to be either a layer of water or ice that  surrounded the earth and produced more air pressure and held in more oxygen. This caused people / plants and animals to live longer and grow larger. The proof in this came when some scientists put a tomatoe plant into a concealed chamber and added what they guessed would have been the amount of pressure and the amount of oxygen. It relatively wasn;t much more oxygen, but everyone knows, toamtoe plants do not survive very long. Well, the plant they had was 14' tall / 10 years old and had baseball size toamtoes. It was a cherry tomato plant. Now, if you look at the "dinasours", you'll actually notice, that their nostrils are realtively tiny compared to the rest of their body. It was easier to breath in that type of condition. So, if you took a crockodile and it grew 10-12 times the size they do now, imagine what they would look like and how their bodies would even change. The reason people live less long, is because that atmosphere that once existed is gone. And in reality, when the flood happened, the safer barrier was removed from around the earth and we're now basically living in a junk yard. In space, there still exists a moisture band around the earth, but nothing like it was before. The water or ice shield came down as a part of the flood. Even today, people heal faster in the containers with more pressure and oxygen and I think even fottball teams have those chambers to help the atheletes heal quicker.

the celts came along much later,in fact around 7000years later,there is a program that was on the history channel about the early brits,it showed some of  the places that they built over 9000years ago and according to this historian they were very advanced,in fact he said that they were building when the rest of the world were still wearing animal skins and living in caves,the historian has been studying this after he decided that other cultures have been studied time and time again so he wanted something different,

Well I think it is because God was roaming the earth. There was no war, there was no sickness, there was peace and that's why people back then lived a lot longer than they do now. :)

Short people tend to live longer than the tall ones.

Their houses were made of thick grass. For the house roping they used tree branches. Sometimes they were called LONG houses because they made them longer.. I suspect for more people to live

They started splitting apart during the Jurassic periods (yes, when dinosaurs walked the earth...) about 170 million years ago, give or take.

I think through evolution and weather changes, the neandrithals migrated to different parts of the world like dinosaurs.  Some cultures evolved faster than others and some were delayed through difficulties with reproducing at higher rates and also lack of technilogical information.

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.

.... i not sure , they grow in layers though, calcium i think .?? i do know this , they are not skeletons of dead creatures... cretin

According to the Bible, I think Methusaleh lived to 930 years (or was it 970?). This was probably because the Earth was very different before the Flood, and people lived for much longer.

The fossil record doesn't show any kind of trend towards smaller body size in the hominid lineage.  The earliest hominids, like Australopithecus afarensis, were much smaller than we are now, perhaps only 3 or 4 feet high.\n\nIf anything, the trend has been towards larger body size.  Homo sapiens in general is taller than Homo erectus was, which was taller than Homo habilis and so on.\n\nEven the off-shoot population of European neandertals were shorter than average human stature, but had more massive bones, with higher density than ours, and may have been noticeably stronger.\n\nThere was one off-shoot that may very well have shrunk in size.  Homo floriensis was discovered a few years ago as remains on an Indonesian island, and appears to have been a dwarf form of human.  Dubbed the 'Hobbit' by the popular press, it may well turn out that this was a tiny species of human, only 3 foot high, that lived in the area at the same time as Homo sapiens sapiens.\n\nDwarfism is a common adaptation found in island species isolated from the mainland.  Dwarf forms of elephant once existed on Malta, and a dwarf mammoth survived on Wrangel island until only 5000 years ago.\n\nUnfortunately, only two workers really examined the Homo floriensis fossils.  One is the dude who put forth the claim of a new species, and the other one claims they were just the remains of a regular human who suffered from dwarfism.  The fossils were smashed beyond recognition on the trip back, and each researcher blames the other.  And then the Indonesian government refused all research permits for the area since that time.  So we're still waiting to hear for sure as to what those fossils mean.
