Science as it should be.
Ever changing with new knowledge.

[Verlos]

I recognize that it's more speculation at this point, but I think it's important to note that the Deccan traps are basically at the antipode of the Chixculub crater, where the seismic waves would have converged. Volcanism might very well might have been the result of the impact itself, or at least an incredibly powerful accelerant.

[boejudden]

When I was a kid in the late ‘90s, all my dinosaur books said that scientists hadn’t yet agreed on the asteroid being the primary cause. It’s weird to think how our understanding can change in such a short period of time.

[jayjohnson]

Saw an episode of Nova years ago about core drills of the chixilub crater. They deduced the magnitude of the impact by studying shocked quartz. From that and the crater they deduced that ejecta from the impact came back down as billions of small particles that burned up in the atmosphere and turned the entire surface of the planet into a pizza oven. Furthermore, the crust in that region was rich in gypsum, which caused the atmosphere to become loaded with sulpher dioxide which reflected a LOT of sunlight causing the intense winter AND produced enough acid rain to poison the earths surface and change the chemistry of the oceans….. killing much of sea life. So large animals were baked, frozen, starved, and poisoned.

[scytheslash]

At 4:00 the volcano isn't located IN the current location of the Indian subcontinent, the Deccan traps themselves are a 'large igneous province' and their formation was most probably driven by eruptions coming from a mantel plume located under what is now called Reunion Islands as the Indian plate drifted over it going northwards, after its separation from current Madagascar and the African plate. This volcanic activity still continues at the Reunion hotspot in the Indian Ocean, similar to how mantel plumes made the Hawaii islands.

[Simmonsumers]

In large scale extinction events it is almost NEVER one single event that leads to it but a collection of events that culminate and compound together to make survival extremely challenging. Saying it was the asteroid alone is a bit silly from the start.

A new theory involves huge methane build ups in the atmosphere and T Rexs arm length becoming long enough to smoke cigs

[RikJSmith]

Great Video , Anton !! I love this Topic and you did an amazing job of putting this Video together . I hope you and your Family are doing well and staying safe .

[steverey]

As a parrot owner I see one flaw off top with the explanation. That being that birds process 100% of what they breathe in, hence the use of canaries in coal mines to warn of methane deposits being released into the mine. If the world was covered with dense smoke enough to kill off large plants the birds would have died off likely before the large plants would have. To me, that's a fatal flaw in the explanation.

[davidbarrass]

I can remember hearing a similar theory in the early 80's. One of the points they made was that being a large animal really helps when it's cold, but when it's hot you just have too much volume and too little surface area. You just can't lose heat fast enough and die.

[brandoncornwell]

I’m glad Anton qualified the assertions of the study b/c even a year or two of dramatic reduction in photosynthesis due to dust and even a temporary large dip in temperatures could easily have been the primary cause that finished off all the Dino megafauna, and the dramatic loss of aquatic life supports this event timeline. I definitely think a lot more data is needed. The Deccan traps erupting for however many decades/ centuries also may have been directly resultant from the asteroid, being approximately antipodal and certainly would have led to a dramatic warming after an even more immediate cooling

[MA]

Between the KT boundary, the projected physical effects of the impact and the maybe simultaneous Deccan traps, we still have an extraordinarily good reason to assume the impact killed the dinosaurs.

[floz]

This channel is so cool, I really appreciate your topics and explanation of things.🍻

[JayCross]

I have the impression that taking continental drift into account, the deccan traps are on exactly the opposite side of the Earth from the Chicxulub crater. It seems plausible that they were a result of the seismic waves from the asteroid event constructively interfering.

[holyworrier]

Fascinating, Anton. I hope you're in generally good spirits, these days.

[tomraw]

I appreciate your new information on this topic Anton.

[thezood]

Imagine all those dinosaurs dying of starvation in such a short time span. It must have been hell. Heartbreaking

[alexanderstone]

The idea that there was a long impact winter has always baffled me. The shear number of Crocodilians that survived the catastrophe is direct evidence against it.

[dennistate]

Anton your indefatiguable cheer and steadfast industry to learn inspire more than knowledge -- respect, patience, and -- dare i say -- yes -- hope!

[yomogami]

thanks for the information anton. we look forward to more updates
