There is a layer iridium through the entire PLANET from the asteroid that killed off many of the plants (food for dinosaurs) thus killing off the dinosaurs. Many scientists originally thought that the heat and dust of the asteroid impact could have caused the K-T extinction. We know that the most common Jurassic dinosaurs were the Camarasaurus. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth’s climate that happened over millions of years.

But it does appear that they were probably very intelligent. Here's what we know about COVID-19 … Absolute dating relies heavily on radiometric dating techniques that looks for isotopes of known radioactive elements that have a very predictable rate of decay. Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years. About 70% of all animal life on earth died out. Let students know that they will be trying to decide some things about dinosaurs from what dinosaurs left behind. New Evidence Shows Asteroid Killed Dinosaurs. Many scientists who study dinosaurs (vertebrate paleontologists) now think that birds are direct descendants of one line of carnivorous dinosaurs, and some consider that they in fact “We are suggesting that, in fact, if you break up an object as it comes close to the sun, it could give rise to the appropriate event rate and also the kind of impact that killed the dinosaurs.” Loeb and Siraj’s hypothesis might also explain the makeup of many of these impactors. No matter what caused the change, it was the inability to adapt to this sudden change that, in the end, killed the dinosaurs.

Dinosaurs went extinct because of a meteor, not because of themselves. During the Mesozoic Era dinosaurs dominated all habitats on land. The author is just making the point that we know quite a lot about them now, so we understand that their role in the present climate change is fairly small. This article from the NASA Astrobiology Institute raises some issues in the accepted theory that the mass extinction event of the late Cretaceous was caused by a meteorite impact. Where did dinosaurs come from, and what killed them off? But we also need the Bible to understand much more that God our Creator wants us to know about our history, ourselves, and about Jesus Christ our Savior .

Like many other questions we have, we can leave them in God’s hands, who reigns in unimagined realms. Their goal is to learn more about the asteroid impact some 66m years ago that many scientists believe killed the dinosaurs. Those clues to what dinosaurs were like are found in fossils—the ancient remains of an organism, such as teeth, bone, or shell—or evidence of animal activity, such as footprints and trackways. Other possible explanations – or contributing factors – include: Climate change caused by volcanic activity in an area known as the Deccan Traps in India.
