How did the dinosaurs die? Did they just disapear or wither away. No one knows for sure but most evidence points to an asteroid crashing in the Yucatan peninsula that caused the extinction of dinosaurs. There are five main points of evidence supporting this theory. There is a 150-kilometer-wide crater in the Yucatan peninsula. Around and in the crater are rare metals that wouldn't normally be found in that region. Melted rock is also found around the crater and even miles away showing that an asteroid crashed and blasted rock around the surrounding region. Scientist's have also found fractured crystals which are found after fast and explosive impacts.
Fossil records show that during the time period in which the dinosaurs went extinct that their population was not in decline or trouble. Even with all of this evidence there still are other theories.
The other main theory is volcanic activity causing extinction. This theory is accountable and does have evidence but asteroid blasts and volcano explosions do show the similar types of evidence after impact and eruptions.
After the research I've seen my opinion is kind of mixed but out of all the theories one of these two is correct but we wil never officially know what killed them unless we traveled back in time.
