Can anyone help me with facts that support the theory of the extinction of dinosaurs???

Question

I need facts that support for Paleontology, Geology, Astronamy, and climatology! for example-"paleontology is a big part of the extinction of dinosaurs because scientists have found bones and fossils to support it."

Answer 1

Geology is important because we can tell the age of the rock in which a fossil is lying and see that the dinosaurs died out at about the same time all around the world. It also gave us the iridium layer, which suggests that a meteor caused the extinction.

Astronomy is important because we could find large rocks orbiting the Sun, which means it's possible a meteor could have caused the extinction.

Climatology is important because many theories about the dinosaurs' extinction are based on climate changes, caused by volcanos, a meteor, or just plain some kind of natural change in the Earth's dynamics (it may have happened slowly due to continental drift, for example).

Answer 2

Currently, the most widely believed theory is that the dinosaurs were wiped out by a meteor the size of Mt Everest striking the modern-day Yucatan Peninsula in southeastern Mexico. A geologist working for an oil company discovered evidence of the crater (now buried) in the Mexican village of Chicxulub quite by accident. This is your geological evidence.
As for paleontology, fossil hunters have found that the record of dinosaur fossils abruptly ends where the rock is younger than 65 million years old.
In the astronomy field, just look at how many asteroids are still drifting around in space. A few of them have orbits that take them frightfully close to earth.

Answer 3

I don't understand your question because paleontology literally means the study of fossilized bones.

You need to come up with a supportable thesis sentence. Such as, the example only,

Marshmallow rice krispie cookies were a big part of the extinction of the dinosaurs because scientists have found fossilized marshmallows and fossilized rice krispies among the dinosaur bones.

Silly example I know but it gives you an idea of what they are looking for.

Try looking up information about the K-T boundary, Mexican Meteor Crater, World-wide Iridium deposits, or Luis Alavarez.

This will give you a good starting point for your research.
