What caused the extinction of the dinosaurs?

TL;DR:

The extinction of the dinosaurs is a captivating mystery. There are numerous theories as to why dinosaurs died out but none have been confidently proven.

from the old testament

  • Many creationists think that the flood of Noah's day (Genesis 6—9) led to the extinction of the dinosaurs.
  • Job 40:15-24 describes behemoth, a large, land-dwelling creature that lived near water.
  • Job 41 describes leviathan as some kind of sea monster or dragon.

from the new testament

  • The New Testament does not mention dinosaurs.

implications for today

We find the fossilized remains of giant reptiles all over the earth, yet we do not see any of these creatures alive today. What happened to them all? The conventional paradigm says that the dinosaurs mysteriously went extinct around 65 million years ago. An assortment of explanations has been offered as to why. The two most popular hypotheses to explain dinosaur extinction are the Impact Event Hypothesis and the Massive Volcanism Hypothesis. The first proposes that one or more asteroids struck the earth, causing a “nuclear winter” that wiped out the dinosaurs. The second blames intense volcanism—sustained, widespread volcanic eruptions—for their demise.

Both hypotheses of dinosaur extinction are supported by some evidence while being challenged by others. For example, if either hypothesis is correct and there is a 60+ million-year gap between man and dinosaur, how then do we explain petroglyphs and other forms of ancient art that appear to depict humans interacting with such familiar dinosaurs as the triceratops, stegosaurus, tyrannosaurus, and the sauropods? If dinosaurs went extinct long before mankind appeared, why do ancient cultures from every inhabited continent record interactions with giant reptiles?

Along the same lines, flexible animal tissues still persist inside some fossilized dinosaur bones. There is skepticism about how blood vessels, hemoglobin proteins, and whole bone cells could last one million years, let alone 67 million. For reasons such as these, Young-Earth creationists believe Noah’s recent flood is the better explanation of the extinction of dinosaurs.

understand

  • Some believe that asteroid, volcanic, or ice age activity caused the extinction of dinosaurs.
  • Many Christians believe the flood of Noah’s day caused the mass extinction of dinosaurs.
  • If they were rescued on the ark, dinosaurs likely struggled to survive after the flood due to drastic environmental changes.

reflect

  • How do you reconcile scientific theories of extinction with the various Christian interpretations of creation and the flood?
  • How does the extinction of dinosaurs shape your view of God’s sovereignty over life and death?
  • What can you learn about dinosaurs and their extinction based on the Bible by what is explicitly stated and by the implications of that?

engage

  • Why do you think many cultures have similar stories of giant reptiles, and what does that suggest about humanity’s history?
  • How do biblical descriptions of creatures like behemoth and leviathan challenge or affirm scientific interpretations of dinosaur fossils?
  • What do different theories about the extinction of dinosaurs reveal about the relationship between science and faith?
