what killed the dinosaurs?

I think that you are right. Well you are right. Dinosaurs did get killed by a big comet that hit the earth. Also the sun was blocked out so the plants died therefore the plant eaters died. And if the plant eaters died then the meat eaters would starve and then they would die. And that is how the dinosaurs died. \nFrom KitKat

Crocadiles...\n\nSupposing that an impact was the cause of the dinosaur's demise, it would not have been an imediate death.  \n\nAn impact would have thrown dirt into the upper reaches of the atmosphere.  The Sky would have been dark day gray for a long time, and the Earth would have grown cold for years...\n\nThose animals that needed the most food would have died first, and in that order of sucession until the only survivors would have been the small scavengers.  The dinosaurs that could feed on the starved carcasses of the dead.\n\nAnd so the decendents of those survivors have had to continue to evolve to survive this colder and crueller Earth.  \n\nThe would have needed to develop an insulating layer...  Some will tell you the Birds evolved from those survivors, and if they are right then those feathers are a post-Impact survival trait...\n\nThe question has to be if there was an intelligent races of Dinosaurs...  I mean, if we suffered an equally destructive impact today, we wouldn't have the forewarning to see it coming even now...  How much of humanity would survive?  Forty Years of darkness and artic cold...

Dinosaurs became extinct before the camera was invented.

My grandmother, who is hardcore Southern Baptist, says the dinosaurs did not exist ever, that they were just bones planted by someone to support a fantasy. She also doesn't believe space exists.... I don't ask her questions anymore.

If you are talking about the extinction of the dinosaurs when a large meteor hit the Earth and threw up thick clouds than made the world dark for a long time, nobody knows exactly what day it was.

The egg. Dinosaurs were laying eggs way before there were chickens!

Perhaps... the weather during the early part of the Cretaceous was warmer than today (and more uniform.)  I'm actually in the process of writing a paper exploring the possibility of hadrosaur hibernation in northern Alaska.\n\nI took a tour of a dinosaur resource center today.  The tour guide said that ability to adapt is what saved KT survivors.  Crocodiles can go months without eating.  Birds migrate.  Fish could swim to deeper water.\n\nIt is still highly debated to what caused the Cretaceous Tertiary extinction.

Don't think there's such a thing as a komodo rhino. There's a komodo dragon, but it couldn't kill T Rex. Not right away, but if it bit it and ran away, maybe. Their mouth is highly septic.

Aliens (Morflocks) built large laboratories on Earth. And they genetically engineered them out of algae slime. But one day the chief Morflok Alien said", Look morflok the morfloks we morfloked are morfloking morfloked". \n\nSo they went into space and directed a large asteroid to strike the Earth near what is now  Bermuda, (effectively killing tourism there for millions of years.  \n\nBasically the Morflocks had decided that many of the dinosaur's temperament was rather unpleasant and quite nasty.  The Morfloks are a happy and joy-full race!\n I like that better than the Earth is only 9,000 years old (what the creationists teach.

Ahm... bascially you probably didnt hit them hard enough.\nInsects have exoskeletons, like a hard shell on their exterior (think like crabs). To kill them you'd probably have to hit them hard enough to crack this shell open AND cause fatal damage.\nIf on the other hand you see thier guts 'n' stuff all over, then you sprinkle them, and they walk away,...then you have some serious Pet semetary type stuff going on in your water. My advice: move far faaaar away. The ground is sour....

try www.bbc.co.uk.  Although, I would suggest going to your library and borrowing their copy of the movie Walking with Dinosaurs or Allosaurus.  It took me almost a year to convince my 4 year old that dinosaurs no longer live after she saw them.

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.

millions of years ago.....\n a meteor hit the earth causing the dust, dirt, sand, and other particles to fly into the air and stay. at this time the particles caused a darkness which blocked the sun whit prevnted the plants to grow & the herbivores died.... when the herbavores died the carnivores died because herbavors were thier main source of food.

As a late development of the dinosaurs Archeopteryx would have come extinct at the Cretaceous-tertiary boundary about\n66 million years ago (when all dinasaurs became extinct)the cause was a large asteroid that hit he earth off Yucatan in Mexico causing cataclysmic environmental changes.\n\nhttp://en.wikipedia.org/wiki/Archaeopteryx
