How did dinosaurs become extinct?

Answer 1

Dinosaur extinction is still a major enigma of earth history. Within the uniformitarian paradigm, the meteorite impact theory, once considered ‘outrageous’, now is the dominant theory. However, the volcanic theory is still believed by a majority of palaeontologists. Both theories have their strengths and weaknesses. The unscientific behaviour of those involved in the meteorite paradigm change will be briefly explored. Evidence that the dinosaurs died in a cataclysm of global proportions will be presented, such as the huge water-laid dinosaur graveyards found over the earth. Occasional monospecific bone-beds and the rarity of fossils of very young dinosaurs suggest a catastrophic death and burial. The billions of dinosaur tracks recently discovered provide testimony to unusual, stressful conditions. Nests, eggs, and babies are a challenge to a Flood model, but there are enough unknowns associated with the data that solid conclusions are difficult to draw. The part that impacts and volcanism play in a Flood paradigm will be briefly discussed. The question of whether the K/T boundary and the extinction of the dinosaurs should be considered a synchronous event within the Flood will be considered.

Answer 2

There are a number of ideas, but little conclusive evidence. What we know is that at the change in rocks that we recognize as the Cretaceous/Tertiary boundary, dinosaur fossils stop (along with a whole bunch of other animals, both land- and sea-dwelling). This is assumed to mean that dinosaurs became extinct at or shortly before the end of the Cretaceous Period. Why they went belly-up is not certain. It's been shown that there was at least one tremendous meteorite impact right near the end of the Cretaceous that might have been enough to do them in. There are also indications of huge amounts of volcanic activity for a while before the end of the Cretaceous in the area of India, which might have affected life on Earth. Other possibilities include climate change, disease, radiation from space, or some combination of these things, or something else that nobody's thought of yet. It's really hard to do more than guess about something about which we have so little real evidence and no evidence connecting the potential cause to the effect. Right now the best bet is the meteorite impact causing enough problems that there was a mass extinction that included the dinosaurs.
Oh, and as a side note, polysyllabic pontifications do not constitute evidence of scientific thought, Eric. Most scientists try to be clear. Ponderous logorrheic literary formulations generally indicate that you either (a) have something to hide (see Politics) or (b) want to "baffle them with BS" (see Advertising)

Answer 3

Evolutionists say the dinosaurs died out about 65 million years ago. How? Well, 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.

Many evolutionists though, don’t think dinosaurs are extinct anyway. The entrance to the bird exhibit at the Cincinnati zoo in Ohio 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).

Many creationists believe the flood would have drastically changed the climate of the earth (cooler temperatures, more radiation, etc.), and that there was a short ice age after the flood. Some creationists think the dinosaurs that survived the flood where not able to cope so well in the new environment. They also believe that is the reason why man’s life-span shortened so much after the flood.

Another possibility is that dinosaurs may have become extinct for the same reason that many animals become extinct today. Why do we have endangered species programs? Extinction is the rule. Why? People killing them, lack of food, man destroying the environment, catastrophes, disease, genetic problems, and so on. I’ve read that in the last 350 years, about 400 species have disappeared and some say the number is much greater. Countries all over the world have stories of dragon slayers. Perhaps man killed them for food, sport, or because they were a nuisance. I think we just didn’t start our endangered species programs early enough.

Another thing, is that there have been (even recently) reports of strange animals in the amazon and the congo that sound a lot like dinosaurs. And there are reports of giant flying reptiles in Indonesia, and so forth. There are thousands of square miles of almost impenetrable swamps and thick jungle in the world. Natives in some of these places describe beasts that fit with what just might be dinosaurs. And what about all the sightings of lake monsters?

This is a field called cryptozoology—the search for hidden animals. There just might be a few dinosaurs left, teetering on the edge of extinction. We are constantly discovering new species of animals and plants in remote areas. A tree can’t run away and hide and yet the Wollemi pine tree avoided detection until just recently (said to have become extinct millions of years ago). An evolutionist has to say, “No way.” But a creationist has no problem with this and can say, “Maybe.”

Answer 4

if im assisting you with homework, im not proud. DINOSAUR EXTINCTION Why did dinosaurs exchange into extinct? there have been many suggestions to describe why dinosaurs grew to alter into extinct. a minimum of fifty 5 distinctive theories have been stated and then thrown out through fact of issues. working example, an theory that works for the super animals many times would not clarify the extinction of the small animals or sea creatures. besides the fact that handed off to dinosaurs, scientists agree that it could have affected the completed international

Answer 5

I believe that there was a climate change and they all died out but their might be some ancestor of the dinosaurs living today in the seas and on land. I believe the komo dragon might be one.
They just couldn't live up to the climate change and died out.

Answer 6

I wonder if it was due to an earlier global warming episode? I believe I heard it was due to some large object hitting the earth down Mexico way thousands of years ago.

Answer 7

There are many theories, but the one most commonly accepted is that there was a comet that hit the earth, and caused so much cloud cover that there was global cooling, and months of darkness.

Answer 8

possibly due to an asteroid hitting the planet,and the aftermath it caused

Answer 9

some say that a meteor came down and killed the dinosours.But we don't know for sure

Answer 10

They didn't fit in the ark so they all turned to stone.
