because back in the 1800's there was this huge asteroid that hit the earth. since it was so big all the dinosaurs in the world all died and now u can find dinosaur tracks on the ocean floor, rivers, lakes, and other bodies of water.so they died and became extinct because of the asteroid. that's how it happened

Scientists have many theories about what caused the extinction of dinosaurs. Below are thoughts on some of the most common theories:
-------------------------------------------
It mst also be pointed out that the avian type dinosaurs (the birds), did not become extinct and are living today.
We think a huge comet or asteroid killed the dinosaurs.
We don't know for sure, but we have evidence. A crater several miles in diameter has been found, with proof of extreme shockwaves meeting up at the exact opposite side of the globe and causing a massive earthquake. The combination of asteroids, shock waves, earthquakes, volcanoes caused by earthquakes, and the ash from all of those forces combined blocking out the sun for years because of its quantity and dinosaurs breathing the ash, the dinosaurs didn't stand a chance. We do not know if it was a chain reaction, such as the ash blocking the sun killing the plants, which starved the herbivores to death, which starved the carnivores to death. Some people believe there was a volcano that blew its top and was so huge, the lava swept across the globe. But I say, if that happened, the lava would have melted all evidence of dinosaurs, bones and eggs, for example. I have seen the massive crater with my own eyes, and so I believe that an asteroid's shockwaves killed the dinosaurs.
But, feel free to decide for your self.
there are lots of theries of how the dinosaurs became extinct and no one can really say which one is forsure the correct answer.
Because of the Boulder that had fell down onto the earth and killed them all and they didn't have any food or shelter so what they did was they were trying to find it and what happened mostly died

asteroid impact
A harmful genetic mutations
A meteor impact caused the extinction of the dinosaurs.
The dinosaurs all died out. A major catastrophe, probably an asteroid impact, caused their extinction.
scientists think that a metoer hit where most dinasores were living at that time that's what they thought that caused the extinction their are still some dinasores that have been discovered but not in ca (tiwan india.........)
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.
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.
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.
Most dinosaurs died off about 65 million years ago. Most life on Earth ended 65 million years ago during what is called the Cretaceous-Paleogene extinction event. There is substantial scientific evidence of an asteroid or comet impact on Earth that caused or was the primary contributor to the extinction. A few scientists still hold other views, including a massive eruption of volcanoes. See related links.
The event that was marked by an asteroid hitting the Earth 65.5 million years ago near modern day Chixulub in the Yucatan Peninsula in Mexico is known as the K-T or Cretaceous-Tertiary Extinction Event.
No. Scientists believe that a giant meteor hit the Earth, killing all the dinosaurs and causing their extinction.It is true that the extinction of dinosaurs is mostly due to the meteor that hit earth during the time but according to scientists, only around 60 percent of the organisms on earth died due to direct impact. Some other reasons the dinosaurs are extinct may have included climate change, competition, or volcanic eruptions. And on the part about tsunamis, there actually was a massive tsunami near the Gulf of Mexico after the disturbance of the meteor that swept nearly 180 miles inland. But it was the meteor that caused the tsunami and also then the meteor, not the tsunami that may have contributed to the extinction of dinosaurs.
Iridium is the rare element that is said to have caused an ancient health crisis (extinction of the dinosaurs).
Many people actually believe that A large flood killed all of the dinosaurs, A large earthquake caused the crater that engulfed the dinosaurs, or A large volcanic eruption resulted in global climate change., but no. it was actually that of A large asteroid strike resulted in a massive explosion that altered plant life. It created an explosion so big that it basicly wipes out the entire species of dinosours!
