Why did the great reptiles of Prehistoric Times suddenly disappear from the face of the planet?

Answer 1

Many people belive that there was a tremendous comet impact on the Earth, perhaps several. These created huge clouds of debris that rose into the air and cut down sunlight for years. The plant life on the planet would not be able to make food through photosynthesis and therefore theanimals that ate the plants died off. The animals that ate the animals that ate the plants died off too!!! Suppose it is possible since the source of all energy is green plants. That is why they are called Producers and everything else consumers (or decomposers)

Answer 2

I am a fan of the meteor or comet hitting and changing the weather, but I do not think it killed off everything. Evolution and genetics shows us that, as Jurassic Park character Ian Malcom said "Life will find a way..." they just recently found usable DNA tissue off of a Tyrannosaurus Rex and found that the closest genetic structure of a living animal was a chicken. Don't forget that turtles and gators are proof, both lived in the time of Dinos and are still here now! Also it is possible although farfetched lay dormant or living in a remote area were humans have yet to ruin.... in the past recent years there have been discoveries in asia of animals that were thought to be extinct, for example a giant squid "the Kraken" tentacles reaching 30 feet long. Tentacles have washed up on shore off of asia for years and they finally found one a little while ago. A fish with limb-like fins that we thought was extinct was caught by a fisherman not long ago.....

So maybe we havent uncovered them yet... maybe some evolved to better suit their ever changing enviormant, most probably died off, some were able to stay the way they were and combat and/or find an area that wasnt effected as much by the weather (turtle and gators) Maybe due to evolution lizards and reptile are getting smaller as the human factor gets larger.

All I know for sure is that reptiles are probably the coolest frickin' things on this planet...

Answer 3

i assume which you advise the extinction on the tip of the Cretaceous. there have been numerous theories however the present superb wager is the meteorite collision thought. this is subsidized up by using there being an rather skinny layer of iridium wealthy clay international and additionally a layer of fractured quartz debris in the same layer. Iridium is rather uncommon in the international yet meteorites comprise an significant ammount. A collision could unfold this factor around the earth and the fractured quartz could be produced on the same time by using the collision. the potential of this collision could be huge and plunge the earth right into a glacial iciness. A crater at Chixilube in the Yucatan peninsular in Mexico has been got here across that has the properly suited age. on the same time as this journey there grow to be a large basalt eruption in India now reported as The Daccan traps. this could have produced aerosols that would desire to have cooled the ambience (sulphur dioxide). the two events could have produced a cooling, in all risk sufficient to kill off the chilly blooded animals like the dinosaurs. Why alligators and crocodiles survived I have no thought.

Answer 4

The Dinosaurs were in decline by the time of the late Cretaceous. There are some palaeontologists who believe they would have died out sooner or later, but the ultimate cause of their extinction is said to be a meteor, comet or asteroid impact near the Gulf of Mexico.

Not only would such an impact have had catastrophic effects upon the Dinosaurs anyway but it apparently released an enormous amount of sulphur into the atmoshphere which caused much of the rain that consequently fell to be similar to sulphuric acid.

It is believed that the Dinosaur populations could not cope with the violent changes to their environment and they became extinct around 64 to 65 million years ago.

Answer 5

You could also ask what happened to all the amphibious life forms before the dinosaurs, they appeared to 'vanish' over night. From fossil records we don't know enough about dinosaurs, but why does everybody assume they were 'reptiles', from the information I've been able to sift through I've come to MY own conclusion that they were in a divide between birds and reptile, traits of both, warm blooded, but reptile like. Some reptiles smell to me 'sickly sweet' others not so, could this be primitive type dinosaurs?

Answer 6

Who knows. Beside those that scientist are saying, about comet, disease and so on, maybe they are transported here from another planet to leave to die. And they did. I believe once a time machine can be built, we will know the answer. But I am sure when that days come, the earth should have been destroyed. Don't ask me why. ^_^

Answer 7

Good question - no-one knows for sure but it's most likely a giant comet crashed into the planet causing a cataclism and wiping out the giant dinosaurs.

Answer 8

Just to clarify things the word 'prehistoric' implies before written records. The dinosaurs died out millions of years before humans even existed so it is prepreprepreprehistoric.

Answer 9

The dinosaurs did not suddenly disappear.
There are many written accounts and depictions of dinosaurs.
http://www.genesispark.org/genpark/ancient/ancient.htm
Remember that the word dinosaur was invented in 1841. Before that people used names like dragon.
People from all over the world have accounts of dinosaurs: the Chinese who have incorporated it into their lunar calendar, The Welsh who have the dragon in their flag; The account of the Saxon Beowolf; The native american thunderbird; and other stories from many other nations. The Romans even made mosaics of them.

Furthermore, dinosaur fossils have even been found containing blood cells - hardly 65 million years old.

But check the evidence for yourself - don't by brainwashed by dogmatic evolutionists who don't want us to think for ourselves :)

The main reason they've died out is most likely because they've been hunted to extinction - good old St George.

Answer 10

They were bored with the samey clubbing scene in this Galaxy, so they popped across to Andromeda for a bit.
