Volcanic eruptions in India, not meteorite, killed dinosaurs

Volcanic activity from the Deccan Traps in India, not a meteorite impact, may have killed the dinosaurs, according to a new study.

Interesting, but fails to answer one important note that has been seen in old palaeontology journals.

The lower Deccan traps (N.) contain dinosaur bones & eggshells in the soils developed above each individual flow.
The upper Deccan traps (S.) contain mammal bones in the soil developed above each individual flow.

In between, there was the K-T impact and likely also a very thick lava flow caused by relaxation of the crust above the magma disc. This would have been a natural consequence of the seismic shock caused by the impact which would have broken every subduction megathrust on earth and relaxed the crust of every tectonic plate.

This would of course make the Ir anomaly rather difficult to spot as the bulk of the dust would have landed on a large plate of pahoehoe lava with likely a lava lake on the highpoint. Look instead for a very thick widespread flow with an Os & Ir anomaly in the lava.

Prior act, impact act, and post impact act would not have killed off the Dinos, but would definitely have produced a Jurassik and early K style generic winnowing effect, with several genera becoming extinct.

The K-T impact however, inducing 6 months of darkness followed by a dust in orbit haze would have shut down the plant based food chain leaving only detritivores, saprobes and their predators as the remnant lifeforms. The reason that the Dinos went extinct & the birds (closely related) did not was a size & ecological niche effect based on the detritivore food chain which the birds & mammals tapped into and the dinos did not.

Actually it was that global warming cooling thing that killed the dinosaurs.

Couldn't it be the combined destructive power of the 2? It's more probable to think both happened at the same time.

No global warming cooling.

The climate mode @ the KT time was mode#3 which is currently only just warm enough to function,(it switched ON in April 2012).

@ that time with large CO2 input spikes from averages of a 1000Km3 volume lava flow per milennium, the climate mode was running hot and very efficient with a lot of rain over the polar circle ring due to heating latitude elevation of the temperate rainbelt. The hot ocean provided a huge buffer heatsink to maintain the climate and run the mode irrespective of the continents (ie. the weather overrode them).

The KT impact would have produced 6 months of darkness + a considerable amount of time shaded by residual dust in orbit.
The result would definitely have been global cooling, however the hot ocean of the KT time is a huge heatsink buffer which would have had its heat extracted by the still ongoing climate mode#3.
It would have been dark, and it would have rained like hell with the bulk of the dust/mud fallout in the temperate rainbelt ring which would have dropped latitude from the arctic/antarctic circles, down to latitudes of around 50 degrees during the darkness and dust in orbit phase.

Any warm weather adapts in the equatorial and tropical regions would have survived without chill (albeit a bit windblown...(at least until they starved to death).

Climate mode#3 continued uninterrupted past the K/T impact until at least mid Miocene in the tertiary.

That takes care of the climate, although you are probably well out in your estimates.

What about the displacement of the oceans over the land masses.
The 3 or 4 or more, hundred mile an hour wind storms.
The years of acid rain and fallout.
The worldwide earth quakes, and volcanic eruptions.

That meteor rocked the planet so much so, it still wobbles today, 65 million years later,(the procession of the equinox's it's called.
The earth was probably thrown from it's orbit, which would have a massive affect on global temperature,( it would have resumed it's normal orbit after so many hundreds of years because of weight, and size, etc, which influence it's natural distance from the sun).

Idiots!Global warming definitly did not kill the dinosaurs, global warming is caused by humans and humans did not live in dino age, secondly caprolite1 your only part right!Stop acting like scientists you are not paleogists(whatever you call dino experts)

Global warming is a natural fluctuation of the climate that has gone from day one. Humans have some but little to do with it.
And Spino guy how do you know what I do?

I do not understand why most amphibians, reptiles and fishes made it through the KT event, if the so called "Impact winter" did happen the world would be thrown into a deep freeze, cold-blooded creatures can barely deal with a sudden drop in temperature

If global warming only started now it would take 300 years maximum to destroy the atmosphere, if global warming killed the dinosaurs 65million years ago, we as humans will never have lived today.Global warming is carbondyoxide which is caused by cars exaust pipes so we are responseble for the atmosphere.

I think the clue here is that they survive well in water.
Though the worlds oceans were in turmoil, the creatures that lived in it would survive in overwhelmingly more proportion than land animals.

Global warming is caused by certain trapping heat inside the atmosphere heating it up carbon dioxide is the main gas that causes this, cars and other vehicles' exaust pipe is not the only thing that produces carbon dioxide, the process of breathing in animals produce carbon dioxide too. Plants uses solar power to turn carbon dioxide and water into sugar and pump out oxygen as the waste product in a process called photosynthesis. In the dinosaur global warming theory dinosaurs' enormous appetite made trees have trouble keeping up and their farts produces methane which trap heats better than carbon dioxide furthermore Volcanic eruptions such as the Deccan Traps in India boosts this process up creating a massive global warming, the temperature could've rose up to 8 degrees ( that's huge) destroying the environment breaking food chains, ecosystems and ultimately the dinosaurs.

Did not die because of global warming they died because a space rock hoit earth which cause volcanic eruption, and fire which the rock also caused alot of dust to block the sun and cause a massive ice age which some how killed the plants, which starved to death herbivores and no herbivores no carnivores,also the fire destroyed many of their habitats.And the climate changed after the ice age killing the remaining dinosaurs, global warming had nothing to do with it at all you idiots.How old are you guys 3.

Spino guy can't think beyond religious dogma he's a fanatic.

He believes God is the answer to everything, and scientific fact is an illusion.

His kind destroy those who do not comply.
Not out of hate, but for the love of God!

Religious fanatics will not be reasoned with.
He is a danger to mankind.
