theories on dinosaur extinction?

Answer 1

Evolutionists say the dinosaurs died out about 65 million years ago. How? Well, I’ve read that there are over 50 different theories. Let me just list a few.
-Mammals eating dinosaur eggs.
-New narcotic plants evolving.
-Global cooling/global warming.
-Loss of plants causing herbivores to starve which in turn caused the carnivores to starve.
-A supernova exploded nearby, spraying the earth with radiation.
-A passing comet poisoned the earth with chemicals.

One of the current favorites is the “deep impact” theory proposed by the geologist Walter Alvarez in about 1980. This theory states that a meteor strike caused dramatic climate changes much like a “nuclear winter” which supposedly caused the extinction of the dinosaurs and many other animals. His evidence was his discovery of an alleged world-wide layer of clay with a high iridium content, which is found in meteorites. Well, there are plenty of papers that talk about the problems with this theory. One, is that the earth’s core also has iridium in it that can be brought up by volcanos. Many Creationists believe the flood would have caused the greatest volcanoes that there have ever been, and some believe God pelted the earth with meteors during the flood as well. And why did the alleged impact kill off the dinosaurs while many other forms of life remained healthy?

Plenty of evolutionists though, don’t think dinosaurs are extinct anyway. The entrance to the bird exhibit at the Cincinnati zoo in Ohio has or had a sign that said: “Dinosaurs went extinct millions of years ago—or did they? No, birds are essentially modern short-tailed feathered dinosaurs.”

First of all, bird evolution is one of the most controversial areas in evolutionary paleontology and evolutionists often disagree and criticize each other.

We hear a lot of reports of feathered dinosaurs being found, but what you rarely hear, is that the main candidates are believed by many experts to simply be frayed collagen fibers, or hair like structures that could have supported a frill or crest like those on iguanas, or are on animals that are not dinosaurs, but flightless birds. The drawings are certainly not what we find; they are just the artists’ imagination. Dr. Alan Feduccia, a world authority on birds and an evolutionist, along with his coworkers have presented a substantial body of evidence to support their view that there are, in fact, no known dinosaurs with feathers (they believe birds evolved from different reptiles, but not dinosaurs).

And then you have ones like Archaeoraptor that was proven to be a hoax. Who knows how many times that will happen.

All these announcements of feathered dinosaurs cause a lot of media fanfare, but when they are refuted, there is scarcely a whimper in the media.

Answer 2

Well, there are (of course) more than three theories, but the three main theories go like this - 1) Meteorite hits the ocean at Chixulub, off the Yucatan Penninsula in Mexico. We do have proof that the meteorite did impact here at the end of the Cretaceous, but the question is whether or not it caused the mass extinctions. The impact would have supposedly thrown up massive clouds of dust that would have blocked out the sun for months, resulting in global darkness and cold, causing plants to die, and dinosaurs along with them. The problem with this theory is that small, ectothermic ("cold-blooded") creatures, such as frogs, would have definately been devastated if this were the case, but the fossil record shows virtually no changes whatsoever in the populations of these organisms. 2) Massive volcanic eruptions in the Deccan Traps, a series of huge volcanoe in what is now India. This event would have spewed enormous quantities of toxic vapors into the atmosphere, and perhaps would also have blacked out sunlight as in the meteorite impact theory. The volcanic theory also encounters some of the problems of the impact theory. 3) I'd say that the third biggest theory is that of disease. Towards the end of the Cretaceous Period, the landmasses known today as Asia and North America had just been joined as a result of continental drift and the oceans receding from record high levels. This would have allowed dinosaurs to travel from these different continents, and bring with them new diseases and sicknesses, which would have spread rapidly throughout the dinosaur populations like wildfire. The problem with this theory is trying to explain other extincions, besides those of the dinosaurs, that occured at the end of the Cretaceous, such as those of marine reptiles. (However, these can perhaps be accredited to climatic change as a result of the world's continents changing.)

Answer 3

The most commonly quoted reason for the extinction of the dinosaurs is the collision with a massive object from space approximately 65 million years ago. But it leaves a lot unexplained. In my humble view, if the impact was catastrophic enough to wipe out the dinosaurs (and the marine reptiles) then it would have been catastrophic enough to end ALL life! Yet turtles, frogs, crocodilians, and the precursors of the mammals of today, among others life-forms, all survived. There probably is no one reason, rather a combination of many, that was the reason for such a dominant animal to vanish from the earth.

Answer 4

It was most likely a meteor strike. How do we know? Well...

1) They found a crater of appropriate size and age off of the Yucatan Peninsula in Mexico.
2) They found a layer of iridium, an element rare on earth but common in asteroids and meteors, at the the K-T boundary which is the boundary in the rock layers marking the end of the Age of Dinosaurs and the beginning of the Age of Mammals.
3) If I'm not mistaken, they also found some shocked quartz, indicative of an impact, near this boundary.

Some scientists think that dinosaurs were already on their way out, due to climate change and other factors, and that this was merely the killing blow that finally did them in.

Answer 5

slugs and certain other creatures are hermaphrodites meaning that they can reproduce with themselves, but they do not because it would just be making a clone of themselves. if the whole slug population was exactly the same even a slight change in the environment would mean the whole population would become extinct because they do not have the ability to evolve. this is my theory with the dinosaurs, that the different species died out at different times, and that the species that weren't clones evolved into something else.

Answer 6

Geomatic has a plausible answer. There are two competing theories that are each attractive for their own reasons.
1) Dinosaurs went extinct from smoking
2) Dinosaurs elected a remarkable dense member of their species to high public office. This particular creature, Bushasaur Confabulous, convinced the other dinosaurs they were in imminent danger of destruction from comets of mass destruction. When the other dinosaurs heard of this, they promptly dropped dead of fear.

Answer 7

The two main 'serious' theories are the asteroid and volcano theories, both of which make some use of the analysis of the rocks in and around the K-T boundary (the Cretaceous - Tertiary boundary). The use of K comes from the Greek word for chalk (Kreta) which is found in great quantities in the rocks of the Cretaceous.

Answer 8

The mostly widely accepted and supported one is the bollide impact about 65 mya, which also coincides with a mass extinction. This is thought to have wiped out Ornithischians. Saurischians were not wiped out completely, thus giving rise to modern Aves.

There are some crazier theories like "aliens killed them" or "they got to big to do it" but the giant impact theory is the one that works and holds up to testing.

Answer 9

Most of them died in the Global Flood.
Noah took representatives of the dinosaurs on the ark, and there have been numerous dinosaurs since - commonly called dragons.

Those that think the dinosaurs died out millions of years ago are perhaps unaware of the large amount of evidence indicating that they lived recently alongside man.

There are many written accounts and depictions of dinosaurs.

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

I agree with Geomatic. A massive climate change, along with some major geological events, resulted in the mass extinctions.

Most probably these were caused by a collision with a comet or asteroid.

What is interesting about this is the emergence of other creatures that were better able to adapt to a cooler climate.
