Study Says an Asteroid Impact Caused the Extinction of the Dinosaurs: What Types of Dinosaurs Were There?

Dinosaurs were organisms that appeared relatively early on Earth, and later they all went extinct. But scientists have always been investigating the reasons for the dinosaurs' extinction, and recently a study says an asteroid impact on Earth was the main cause of the dinosaurs' extinction! What are the specific details? What types of dinosaurs were there?

I. A study says an asteroid impact on Earth was the main cause of the dinosaurs' extinction! What are the specific details?

A new British study published on June 29 found that the dinosaurs went extinct because of an asteroid impact on Earth, not volcanic eruptions. The study also confirmed that at the end of the Cretaceous period, 66 million years ago, an asteroid struck Earth at the location of what is now the coast of Mexico. The particles and gases released by the impact blocked the sun's rays for decades, causing a sustained winter. The only dinosaurs that survived after the impact later evolved into birds. Through modeling, the study also clearly analyzed and demonstrated the destructive impact of the asteroid strike on dinosaur habitats.

Previously, explanations for the dinosaurs' extinction also included: the 2000 theory, the meteorite impact theory, the climate change theory, the ocean regression theory, the volcanic eruption theory, the orogeny theory, the warm-blooded animal theory, the mammal evolution theory (the egg-stealing theory), the sudden change theory, the species evolution theory, the frustration theory, and the change theory.

II. What types of dinosaurs were there?

The types of dinosaurs include the carnivorous Zhongjianosaurus, the Coelurosauria infraorder, the Prosauropoda infraorder, the Sauropoda infraorder, the Ornithopoda suborder, the Stegosauria suborder, the Ankylosauria suborder, the Ceratopsia suborder, and the Pachycephalosauria suborder, among others. Most of them had sturdy limbs, massive bodies, and long tails, and mainly lived in open areas or forested areas on lakeside plains or coastal plains.

III. What foods did dinosaurs eat?

Dinosaurs were herbivorous and carnivorous. The plants that herbivorous dinosaurs could eat were limited by their height. Carnivorous dinosaurs fed on herbivorous dinosaurs and other animals. The different foraging methods of various dinosaurs are also reflected in their teeth. In addition, some were omnivorous animals.

The above is the full introduction to the study saying that an asteroid impact on Earth was the main cause of the dinosaurs' extinction. I wonder what views you have on research into the reasons for the dinosaurs' extinction?
