Courtney believes that the dinosaurs went extinct as a result of a giant asteroid hitting the earth. scientists discovered a 150 km wide crater dating back to the time of their extinction, according to the fossil record. the crater and the fossil record are examples of researched data that support courtney’s explanation. true or false

True

Explanation:

Dinosaurs once ruled the planet Earth. Currently, not even a single specie exists. The mass extinction of the dinosaurs is believed to occur due to an asteroid colliding with the Earth which led to creation of an environment in which the survival of any specie was not possible. The dinosaurs got wiped out from the face of the Earth.

On researching for the evidence for the same theory, scientists discovered a 150 km wide crater (The Chicxulub crater buried underneath the Yucatán Peninsula in Mexico) dating back to the time of the extinction. This event is known as The Cretaceous–Paleogene extinction event which occurred about 66 million years ago.

Thus, it is True.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
