How did dinosaurs "die out"?

Question

i want to hear about herbivores.

Answer 1

The leading theory is that a large asteroid hit the earth, kicking up dust which blocked out the sun and screwed with the climate.

A lesser-known theory that is beginning to gain traction in the scientific community is that they died from lung cancer that they got from smoking.

Answer 2

The meteor at the end of the Cretaceous that hit the Yucatan is the most often cited culprit, but there are a few lesser known theories floating around out there. Some experts think that dinosaurs were already starting to dwindle before the meteor (because of disease or other factors), due to the decrease in the number of species found leading up to the impact.

In any case, the vegitation died, followed by the herbivores, and finally the carnivores. Only small creatures that could hide underground or that lived in water survived.

Answer 3

The general consensus seems to be that there was a catastrophic event about 65 million years ago that cause the demise of the large dinosaurs. Probably a huge meteor landed near the Yucatan peninsula and created such a huge climate change with debris thrown into the air that the big dinosaurs couldn't survive.

However..... birds and reptiles are descended from dinosaurs & live on. Some dinosaurs were herbivores and some were carnivores and undoubtably, some were onmivores.

Answer 4

Either it was a large asteroid that hit an area at the northern coast of the Mexican Yucatan-Peninsula, or it was a so-called super volcano, such as the Yellowstone in Montana that erupted around 65 million years ago.
Whichever it was, it turned all life on earth to the verge of extinction. The impact/eruption at the immediate site caused an instant disintegration of all life upon the event. Even thousands of miles away, heat and shock waves leveled literally everything in their path. The ash/dust fallouts suffocated everything else that was possibly still alive.
For the rest of the planet that wasn't affected by the event itself, clouds of dust and ashes thrown into the upper atmosphere darkened the sun for years, perhaps even decades that followed the catastrophic event. Temperatures plummeted probably below freezing even in the tropics, leaving the cold-sensitive dinosaurs slowly to die out.
And the dinosaurs were not the only specie lost to such a global blast; they were just the most noticeable out of so many that vanished.

Answer 5

A large asteroid/comet/rock smacked into the earth, a monstrous cloud of debris was thrown up and blocked out the sun for a very extended period of time (years). Most large plants died from the greatly reduced amount of sunlight (no photosynthesis), some plants obviously survived but not in the numbers neccessary to sustain large herds of massive herbivores, plus the carnivouros dinosaurs still had to eat as well. So essentially what happened was they ran out of food and went extinct. Small mamals were able to survive by burrowing and eating small roots and seeds (hence the rise of the mamals)

Answer 6

The biggest ones were killed off by induced sterility (failure to reproduce) by strange visitors who were looking for a planet to colonize with the physical and mental defects from the home planet. It was done so that we would not be eaten or trampled by the giants. By the time they returned home and built giant cargo crafts to bring our caveman like ancestors here, the giants were gone. Being a wholly benevolent society, they brought us here instead of merely euthanizing the defective ones. We evolved into the semi-intelligent creatures you see around you. The home planet is so far away that man will never see it. But they still keep an eye on us to see if we have killed each other off. Visits became more urgent when they detected atomic and nuclear explosions on earth in the mid/late 1940s. Some young tourists crashed near Roswell, New Mexico in 1947.
(Shhhh! Nyuk!)

Answer 7

Don't believe this meteor blotting out the sun crap. Why do people believe that a meteor of any size capable of kicking up dust to blot out the sun for years, would simply kick up dust and blot of the sun for that long? Any meteor capable of kicking up sufficient dust to blot out the sun for more than one day would have split entire lands masses into several pieces like... seven or so and make the water level rise enough to cover the land in enough water to destroy large amount of plant life and any thing walking on it. Not to mention the amount of mountails that would have fallen and crushed all those living under them. I could go on, but then I would make too much sense.

Answer 8

on the different! To die is a organic and organic technique. The cessation of existence is a metaphorical extension of the theory. That metaphor additionally implies a non-organic and organic ingredient of existence--a soul or spirit, in case you will--because of the fact in maximum cases of dying, there is unquestionably a continuation of existence, many times because of the fact this type of gruesome continues to be that save the particular-outcomes crews busy on "CSI" and "Bones." As to the metaphorical experience, we've not got any foundation at fascinated approximately assuming that passing out of our selection of interplay particularly potential passing out of existence. you in basic terms anticipate it, in simple terms as others anticipate an afterlife. On a miles less philosophical and extra effective point, Christians understand what dying is. We in simple terms assert that it particularly is not extra everlasting a state than our present existence, and that Jesus the two experienced dying and well-known its impermanence. you are able to disagree, even nevertheless it particularly is unbelievably stupid to anticipate that we don't understand what we are asserting. you're arguing from willful lack of information of our place, in simple terms like the creationists who so frequently declare that the theory of evolution misunderstands the character of existence.

Answer 9

The meteor caused loads of dust to fly up in the air killing all plant life as it blocked out the suns and there fore all remaining dinosaurs who ate plants died and all the meat eaters died out as there food had died too.

Answer 10

No .. they died from eating fast food. Their arteries got all plugged up and soon they all died of cardiac arrest. Then they turned into oil..Of course this was milliions of years later. The oil was all the fat in the fast foods which converted to oil.
