The Chicxulub asteroid impact is the leading theory for the mass extinction of the dinosaurs about 66 million years ago. It is not the cause of their extinction though. Not really. Scientists believe a combination of factors contributed to their demise. Volcanic Activity was a huge part. The Deccan Traps in India were erupting massively around the same time. The ecosystems were falling apart well before the asteroid hit. Climate Change was huge as well. Earth was already facing epic climate fluctuations that may have stressed dinosaur populations. Food Chain Collapse was taking its toll on the poor bastards. Massive wildfires, blocked sunlight, and caused plant die-offs, leading to starvation up the food chain.

The meteor was likely the final blow, dinosaurs were already facing serious environmental challenges. What do you think?

Personally, I think it's enough just to recognize the paleontological, geological and zoological records to understand that all historical mass extinctions, and we've had many, had natural causes for which we continue to uncover an abundance of evidence. I just watched a recent NOVA on PBS, "Hunt for the Oldest DNA" which I think is from just last year, and I really appreciate how science continues to be riveting and compelling in my life. I highly recommend it.

Thanks for the Link. We don't get PBS or NOVA here, as far as I know. My dad was a huge NOVA watcher so grew up watching it... and Magnum PI.

I have a book, a few yrs old, that details all of that. 🤷 It's not the only one, of course.

What do I think?
I wonder if Chicxulub asteroid impact is in the global opposite position from the Deccan Traps in India.
Kinda would make sense that a massive impact on one side would send a shockwave through the center of the Earth and cause impact on the opposite side.

I agree, an interesting program.
 
I’m glad they aren’t around now, although there are still a few in congress. They don’t have the tooth and claw bit going for them. They take their teeth out at night, and their claws are glued on. We’re safe from the killing and eating part, anyway.

We still have birds, so it didn't kill all of them.

And sharks and crocodiles... but it essentially got all the actual dinosaurs.

We may have two good hypothesis now to study.

Things so far in the past have one or more weak hypothesis. It is good in my opinion for scientists to consider what else may have caused it.

They are... but that is like saying that Vikings are Black Africans from the Rift Valley in Eastern Africa.



The ones that everybody considers actual dinosaurs. ;)

We're all from Africa. All birds are dinosaurs, too.

That was my point... either parameters matter or they don't.

Agreed. Scientist's conclusions, which are always in flux, are continually considering "what else may have caused it". That's the very thing that drives much of scientific discovery. They never stop considering alternatives. The ones that tend to endure - i.e. the "conclusions" with the most staying power - are the ones that successfully cross many interdisciplinary sciences, because those conclusions have been stacked, one upon another, with supporting science from entirely different fields.

Geology - arguably the bedrock of most succeeding planetary sciences (pun intended) - only dates formally to about the mid-16th century, but since that time as branched into literally dozens of related geological sciences that continue to refine our understanding, not only of the sequencing and the timeline, but the very underlying dynamics of our planet.

But your post provokes a question: What else do you think may have caused the dinosaur extinction?

Except in the climate sciences. They made up their mind. They will not consider other reasons.

This is about the dinosaurs 65 million years ago... not climate change in 2024.

I think it may as often be a mixture of reasons. One I heard of was the procentage of oxygin fell after the impact and so the big animals had trouble breathing. Small Mamals got along better with that change.

There are virtually no dinosaur fossils above the Kpg layer:

However, paleontologists only recognized the full significance of the boundary between the Mesozoic and Cenozoic eras in the early twentieth century. By 1900, about a century of scientific collecting and study of fossils demonstrated that many organisms had become extinct at or just before the Cretaceous-Paleogene boundary. This extinction thus ended what is popularly termed “the age of reptiles,” setting the stage for the appearance and proliferation of the types of organisms that have inhabited the Earth for the last sixty-six million years, or what is popularly called “the age of mammals.”
