From the collapse of a massive magma chamber after it last erupted.
The Yellowstone Caldera, also known as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano estimated to be an area of about 34 X 45 miles (55 X 72 km).
The caldera that covers most of Yellowstone Park was produced by a supervolcano. A supervolcano is an explosive volcano capable of producing an eruption with an ejecta volume greater than 1,000 cubic kilometers. The Yellowstone Caldera is one of the largest and most active supervolcanoes in the world.

No, the Yellowstone supervolcano did not cause the extinction of the dinosaurs. The dinosaurs went extinct around 65 million years ago, while the most recent major eruption of the Yellowstone caldera occurred around 640,000 years ago. The extinction of the dinosaurs is most commonly attributed to a combination of factors, including a meteor impact.
The Yellowstone volcano is actually a supervolcano, and is hidden under the rest of the park. So whenever you go and visit any part of Yellowstone, you are actually walking on top of the volcano itself.
No. Most of Yellowstone lies outside of the Yellowstone Caldera, though this caldera still takes up a large portion of the park. A larger portion of the park is in the older Island Park Caldera, which partly overlaps the Yellowstone Caldera. This still takes up a minority of the park.
No. Most of Yellowstone is outside of the caldera.

The Yellowstone Caldera was formed by an Ultra Plinian eruption. Ultra Plinian is the most violent type of volcanic eruption with enormous columns of ash and gas shooting twenty or more miles into the sky and releasing many cubic kilometers of ash.

The Yellowstone volcano is usually called a supervolcano.
Most of the Yellowstone Caldera is no hotter than you would expect from weather in that climate zone. The caldera does contain many hot springs, and geysers, some of which are hot enough to boil water.

Volcanoes existed on the earth before we did. They helped build the planet. There is a very good chance, seeing as Yellowstone is a super volcano, that it's been here almost as long as the earth has but, there is also the chance it has been forming over millions and millons of years increasing in size (and still doing so) due to tectonic movement. No one can be to sure.It's like asking 'where does space end?'...no one can know for certain, only guess.Hope this helps.
