Could one dinosaur have been alive even after the asteriod hit?

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...

You are nuts!. . .Because the dinosaurs died doesn't mean God failed. . .it means the dinos are in Heaven!  (Except the ones who didn't accept Jesus Christ as their Lord and Savior, and the ones who were gay dinosaurs, or voted Democrat.)

A. Could we have real dinosaurs somewhere?\nAs ttocsewol pointed out, the biggest problem of cryptozoology is that there is not enough space to hide thousands of dinosaurs. If there are fewer, the species is quite vulnerable to extinction.\nOne exception: there is enough space in the ocean. We have just recently discovered some pretty large shark species. However, this means that the dinosaur in question has to be giving birth rather than laying eggs, much like Ichtyosaurus dis. However, marine reptiles of Mesosoic era (Plesiosaurs, Mesozaurs, Ichtyosaurs and so on) are not dinosaurs in strict sense of the word, but are distantly replated to them.\n\nB. Living descendants and relatives of dinosaurs.\nTurtles, crocodiles, lizards and other surviving reptiles are also quite removed relatives of dinosaurs. Birds, however, are direct descendants of theropod dinosaurs.\nBe careful around that chicken.

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

Technically dinosaurs were not even known to have exist until the first evidence was discovered in either the 18th or 19th century. In the book of Genesis note: not to be interepted literally!! It states ( after the life in the sea,animals on land) Sorry I can't quote exactly however; look at all the animals that exist. The Bible would be a LONG book!

The popei plant came around right as the dinosaurs were going extinct... most dinosaurs has really small nasal cavities...\nmakes you think....

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

UPDATED!!!\n\nIt is taken seriously, and is now generally accepted as the primary cause of the dinosaurs' demise.  there may have been additional factors, but a meteorite impact is considered to be the biggest one.\n\nFor a long time, however, it was believed that meteroites only struck the earth in the past, and after that initial bombardment, the danger passed.  And most scientists demanded a "smoking gun."  A crater.  That crater was finally found...under water.  Off of the Yucatan Penninsula.  When the meteorite first made contact with the surface of the earth, the top point of the giant rock was six miles in the sky!!  It left a crater 25 miles deep.  Imagine standing on the eastern edge of the Grand Canyon.  If that was the Yucatan Crater, the other side of it would have engulfed the casinos in Las Vegas, Nevada!\n\nThe confirmation that it was an asteroid (or meteorite) strike that killed the dinosaurs was the detection of an element called iridium, which is common in space, but rare on earth.  Another indicator is the presence of shocked quartz close to the area of impact.  There are no normal geological processes powerful enough to shock quartz, but a meteorite, if it was big enough, could do it.  Then as the meteorite and the rock with which it impacts is vaporized and blown up into the earths atmosphere, the huge cloud of dust spreads out over the world and eventually settles back down\n\nScientists can tell when the impact occured because after a certain level of geological stratus (layers of sediment laid down over time), dinosaurs are no longer found.  At all.  When they analysed the materials in this layer of sedentary rock, they found unusually high levels of iridium.\n\nSuch impacts are not necessarily periodic events.  Such a thing absolutely will happen to the earth again.  Not if.  When.  And nobody knows when it will happen.  Astronomers have identified thousands of Near Earth Objects.  Any one of these could be the next to strike us, or perhaps one that we missed.\n\nBut it WILL happen.\n\n"if the planet would have been in the outer reaches how can it really be so impactful that it jolted numerous rocks towards earth"\n\nBecause that far out in space, very small changes in direction can have major impacts on the objects trajectory after it has traveled millions or billions of miles.  If you aim a rifle at the bullsey of a target that is 100 meters away and move the barrel end of the rifle just one centimeter, the bullet may miss the target completely.  Just that small distance can be a big miss at a long range.  Likewise, if an asteroid is on a trajectory that doesn't put earth in any danger makes only a slight change, possibly no more than the width of a human hair, it may wind up on a path that will cause it to crash into earth, or a different planet.  This change in the asteroid's path may be caused by the gravitational pull of a nearby planet, or by one asteroid gently bumping into another.  And this can happen anywhere.  While the asteroid is in orbit within our solar system, or in what is known as the "Asteroid Belt."\n\n"also if the planet is undiscovered how can they say anything about its involvement with earth being peiodic"\n\nGood question.  For a long time, scientists suspected that there was another planet beyond Pluto.  The reasons for this were that although this other planet could not be seen, its gravitational effects on other objects could be detected.  I don't know what the specifics of this process\nwere, but perhaps they measured a slight "wobble" in the orbit of pluto that had to have been caused by something with enough mass to cause the wobble.  Astronomers referred to this object as Planet X.  This planet has now been discovered and verified.  It was named Xena.\n\nIt should also be noted that the cause of a change in an asteroid's path doesn't have to be cused by a planet that is very far away.  There are

wow that was soooooo long ago,you must be really old.number one was the first t rex went extinct. sorry lol

it was a tyranosaurus rex wasn't it? I'm pretty sure that was it. except for the ones that he'd made up in the mansion of course, we don't know the sequance in which he made those, but the tyranosaurus rex was the first one you saw him do

i think it was just dinosaurs\n\nthat was a cool show, wasn't it?? lol

Holy cow-thats a Master's thesis project at least!  Ok, there are lots of theories out there concerning a cataclymic hit-and since both she and the people she is comparing also believe in the asteroid theory, we have to just think of all the things that could happen, reasonably:\nThe ashes from the volcanoes could block out the sun so drastically that it became too cold for the dinosaurs to live\nThe ashes blocked the sun out sufficiently to kill the major plant life, so the herbivorous dinos starved, and then the carnivores starved.\nThe volcanoes spewed out sufficient CO2 that the dinos suffocated\nThe volcanoes spewed out toxic gas that poisoned the dinos.\nThe volcanoes subtly changed the climate so that over thousands or hundreds of thousands of year, other lifeforms, such as mammals, birds, and the surviving reptiles, gains a major advantage and caused the dino extinction.\nAbout the meteor:  Either you could hypothesize that the volcanoes erupted spontaneously, and it had nothing to do with meteors, or that the meteors by themselves weren't a killing force but disrupted the crust of the Earth sufficient to open up volcanoes all over the Earth, or that the meteor alone killed most of the dinosaurs, and the resulting volcanoes killed off the rest.\nI didnt mention the effects of tsunamis and earthquakes caused by the volcanoes because that wouldnt reasonably be enough to kill off all the dinos.\nHope those ideas help-good luck.

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.

Maybe not in the way we think they did. but yes i think they did. maybe back when there where dinosaurs. i think those are the closest to "dragons".

It is unlikely that a 65 million year old bone will have any real tissue inside.  If you are thinking of Jurassic Park type exploits, the 'real tissue' was dinosaur blood from inside a mosquito that got preserved in amber.  Preservation in this manner is known as unaltered preservation meaning that the fossil was encased at death in a substance that isolated it from any form of decay hence the fossil is exactly as it was the day it died.  Larger animals may get preserved this way in features such as tar pits or by freezing.  Most fossils are not preserved this way and so do not have any real tissue left at all and most unaltered preservation of large animals has lasted not much more than hundreds of thousands of years, not millions.

Oddly, usually they don't.  Usually, a piece of bone is found protruding from the ground already, and that's how dinosaur skeletons are found.

They are still alive, since birds are dinosaurs.
