I'd have to say say meteorites or earthquakes but my theory is a plant infection. If this did happen the Herbivores would die and the Carnivores ate the dead carcasses that were infected and they died. There is also a theory that they didn't die, they evolved.
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 a significant contributor to the extinction. A few scientists still hold other views, including a massive eruption of volcanoes.

There are several theories on how dinosaurs became extinct. The first and most common is the Asteroid Theory. Some believe they became extinct because of volcanic activity and others think it had something to do with the ice age. Others believe it could have been climate change or a new disease introduced to the dinosaurs that eventually killed them all off. All we know is that they are extinct and scientists still do not know exactly what caused it.
One is that it got really cold and the plants died. After the plants died the herbivores died too. When they died meat - eaters also died.
One theory is that a big meteor hit Earth, the second is the volcanic eruptions, the third is the big earthquake and last, is that mammals ate their eggs.
1. The weather got either too hot or too cold. 2. A meteor struck the earth, sending dust into the air that blocked the sun from helping plants photosynthesize.

a giant asteroid hit them
an impact from outer space
Yes. At the time of ther Permian extinction 251 million years ago dinosaurs had not yet evolved. The dinosaur extinction was 65 million years ago.
The prepositional phrase is "about dinosaur extinction" and the object is "extinction." The word "dinosaur" is called a "noun adjunct" rather than an adjective.

Extinction has happened to the dinosaur family.
Dinosaur?
A cockroach
yes
The Cretaceous-Tertiary Extinction was a giant asteroid that hit Earth and killed many organisms. It formed giant dust clouds and enough heat to cause a worldwide fires. The fossils of the dead organisms gave out a story to the scientists who were researching them. For example, a meat-eating dinosaur ate a plant-eating dinosaur during the Cretaceous-Tertiary Extinction. Soon after the meat-eating dinosaur ate the plant-eating dinosaur, the meat-eating dinosaur died. The fossil of the plant-eating dinosaur and the meat-eating dinosaur told a story to the scientist about what the meat-eating dinosaur did to the other dinosaur; then the other story to the meat-eating dinosaur.

If I take a bath in gravy will a dinosaur eat me?
no, scientists have recently concluded that a asteroid killed them
Yes Its Survived The Other Dinosaur Extinction
Yes, the Cambrian Period was before the Mesozoic Era
