How long did the dinosaur winter last?

The impact winter did not last long, however. Over a few months or possibly a few decades, the dust and soot fell out of the atmosphere and rained down onto the land and oceans, allowing sunlight to warm the planet once again.

What are some popular ideas about the cause of dinosaur extinction and why are they not accepted by most paleontologists?

Popular ideas include: egg-eating mammals, extremely hot or cold climates at the end of the Cretaceous, poisoning, a supernova, thinning of dinosaur eggshells and a worldwide epidemic or plague. Most paleontologists reject these ideas because there is no evidence that supports them.

How might the slow drifting of the continents have caused the extinction of the dinosaurs?

According to many scientists, continental drift and ocean regression would have caused continents to become drier, cooler, and less hospitable to dinosaur life than they had been previously.

How cold did it get after the asteroid that killed the dinosaurs?

Previous estimates of the sulfur aerosols entering Earth’s atmosphere after the asteroid impact range from about 30 to 500 gigatons; according to climate models, this sulfur would have turned into sulfate aerosols, which would have caused 3.6 to 14.4 degrees Fahrenheit (2 to 8 degrees Celsius) cooling of the Earth’s …

What was the temperature on Earth when dinosaurs lived?

Dinosaurs of the northern mid-latitudes (45 degrees north of the equator) experienced average summer temperatures of 27 degrees Celsius (about 80 degrees Fahrenheit). Winters were roughly 15 degrees C (59 degrees F).

What dinosaur is still alive today?

In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
