How did dinosaurs become extinct

Chuck norries did not want them alive anymore.

They leveled up too much. It got to a point where, regardless of their ATK and DEF, the resources available weren't sufficient enough to replenish their HP. After all the other dinosaurs died out, the last one was left to wander the earth, and that is when the first Highlander was born.

They ate themselves. Only logical explanation I have come up with.

“How Did the Dinosaurs Die?”

“After Dinosaurs ate everything on Earth, they dug deep into the ground to search for food. Sadly, they became trapped in the hole, which is why their skeletons are found underground today.”

Fun fact: The reason why the Bible never mentioned Dinosaurs is because people in Europe didn’t seriously start questioning and discovering dinosaur remains until the 1800s.

Scientists actually have several of ideas on how they were wiped out (technically they weren't completely wiped out, some survived and lived on to evolve into birds), but the theory that most of them agree upon based on the evidence at hand is that approximately 65.5 million years ago, a bolide (meteor) 5 to 15 kilometers wide hit in the vicinity of the Yucatán Peninsula, creating the approximately 180 km Chicxulub Crater and triggered the mass extinction. The details about how exactly the impact would have killed off the dinosaurs are quite cumbersome, but basically the ash, rock, etc. killed off a lot, and the rest were killed off by the clouds that were formed covering the sun, making it too cold for them too survive. There are other factors that went into it, but this covers the basics.

I know you were joking but you are misinformed. The dinosaurs went on the ark. When would explain all the sightings of dragons and dinosaur bones found in Alaska that look like they are only 100 years old.

They indeed died of hunger. Whether the Earth was hit by a meteor or a massive volkano (Super Volcano - like one below Yellostone, actually the whole place there is a volcano...) errupted doesn't matter, because the same result followed. The sky was covered with dust and the Sun's energy could not reach the earth for a long period of time, thus the some of the plants died, then some of the insects, small mammals and then the dinosaurs. Every living creature is connected in the food chain.

There is one huge loop hole with how everyone is talking about how the dinosaurs became extinct by a meteor or even volcanoes that created huge clouds of ash that blocked out the Sun. And here it is: if the Sun was blocked out for who knows how long to kill off all the dinosaurs, then how the hell are we here today? How are humans and every other freaking creature on this planet here if all the plants died because of the lack of nutrients from the sun, which in turn provides food for the most basic of life forms in which more complex forms of life eat off of?

We really don't pay much attention in school do we?

The most commonly accepted theory at the moment is the a combination of a meteorite strike in the Gulf of Mexico (just above the Yucatan) and a super volcano eruption in India deposited enough dust and other materials in the atmosphere to result in what they now call Nuclear Winter (it is speculated that wide spread nuclear war would result in a similar scenario). As to an earlier poster who questioned whether a meteorite strike could result in that amount of debris ... it is believed that the meteor was approx. the size of Mt Everest, and the resulting crater was approx 150 miles across. At the same time, a super volcano was erupting in India ... it's eruption resulted in lave flows so deep that entire temple complexes have been carved from the lava. It is believed that these two occurrences, happening at the same time deposited enough debris in the upper atmosphere to blacken the sky for several years, resulting in sudden and catastrophic climate changes.

@ Zandorf - regardless of how, at that moment in time between 75-80% of all life on earth became extinct. The resulting climatic changes resulted in favorable conditions for another type of animal, mainly mammals - most of whom were small and more resilient at the time, it was this change that brought about a change in dominance from mega sized dinosaurs to smaller mammals. Basically, without such an event, we probably wouldn't be here in our current form.

Firstly, not 100% of all the plants died.
Secondly, it happened freakin' 65 million years ago. That's a lot of time for the planet to recuperate.

As the user above me said, with dinosaurs out of the picture the mammals could thrive. Also dont forget that Homo Sapiens (ergo us) came to be about 200 000 years ago, long after the cataclysm which destroyed the dinosaurs.

female dinosaurs decided that males were incapable of daily chores, thus they castrated every male dinosaur, and then they died. On a more serious note, Birds are the decedents of dinosaurs, thus the evolutionary path that dinosaurs took is reflected in birds of this day and age.
