Its mostly because of climate change. Example: the sea of Tetis (located where the Sahara stands today) was home for whales and megalodon (the giant shark). When continents shifted, whales moved north and south to colder waters where their food lived. Since whales were megalodon´s prey, and apparently the shark didn´t adapt to colder waters, it went extinct. Same thing could have happened to different species of dinosaurs. Just imagine changing vegetation, different weather, water availability, etc.

A meteor impact caused the extinction of the dinosaurs.
The causes of the natural disasters and plus the wind could possibly tear the continents and make separate continents. Also there could have been a terrible earthquake that caused the continents to also separate.
The dinosaurs all died out. A major catastrophe, probably an asteroid impact, caused their extinction.
Nobody really knows how dinosaurs got extinct.
The mass extinction of dinosaurs were caused volcanoes that cause global warming with their toxic gases, therefore, killing the plants, starving the plant eating dinosaurs to death, and with no more plant eating dinosaurs, the meat eating dinosaurs died, too.
Iridium is the rare element that is said to have caused an ancient health crisis (extinction of the dinosaurs).
Although there is much speculation over what actually caused the extinction of the dinosaurs, a large meteor did, in fact, strike the Earth shortly before the dinosaurs' extinction. The meteor is believed to have been approximately 10 kilometers in diameter. The impact location was the Yucatan peninsula and the event occurred around 65 million years ago. If the dating is correct this places the impact during Cretaceous period, which has led many to believe that the impact event triggered or facilitated the extinction of the dinosaurs.
Possibly. This is one of many theories. We cant prove what caused their extinction. See the related question below.
We are still not sure what caused the mass extinction of the dinosaurs, though an asteroid impact seems to be the popular theory.Scientists believe we may be heading towards another mass extinction event.
Briefly, the theory is that the mass extinction which included the loss of the dinosaurs at the end of the Cretaceous period was caused by the impact of a large asteroid.
Primitive mammals, with fur, did exist during the age of dinosaurs. It has sometimes been speculated that mammals caused or helped to cause the extinction of the dinosaurs by eating dinosaur eggs.
It has been speculated that the mass extinction of dinosaurs was caused by an asteriod, however there is not enough evidence collected to support this. It is still argued possible though.
