"New research suggests volcanoes NOT killer asteroid responsible DINOSAURS were really wiped-out by an apocalyptic volcanic eruption, not a massive asteroid impact, two new studies have shown." I've always said it couldn't have been a 'killer asteroid'. So I guess that makes me smarter than those who said it was? https://www.express.co.uk/news/scie...volcanoes-not-killer-asteroid-mass-extinction
Looks like the OP never bothered to read past the headline again! A massive impact will trigger volcanic eruptions as it would send seismic waves across the tectonic plates causing them to fail at stress points. That would cause massive earthquakes, tsunamis and raging wildfires across the planet as well. Note how the OP disingenuously left out the PERTINENT aspect of his fallacious "opinion" since he erroneously claimed that the dinosaurs were exterminated by disease instead.
Yes I did too - about 3 months ago unless I'm much mistaken; I'm rather flattered that you remember my posts after such a long time.
I am cursed with having a memory that clutters itself with inane trivia. On the plus side it does have an excellent index system whereby it connects the trivia to the originator.
They were hunted to extinction. They were assassinated in a right winged conspiracy plot. They were character assassinated in the media in a left winged conspiracy plot. They sent out a racist Tweet on Twitter one night while taking Ambien and now no one wants anything to do with them. It was either have dinosaurs or have oil, we chose oil.
Man Made Climate Change. Okay not Man Made. Climate Change happens. Desertification as those long necked dinosaurs laid waste to the forests. I mean it. Or just a happening in the Universe and Planet Earth. Climate change.
The “killer asteroid” for which there is world wide evidence, including a massive crater in Mexico, finalised an extinction event Why do you not actually read the subject and inform yourself of facts first instead of relying on tabloid drivel Remember this mantra “Bad journalism is not the same thing as good science
Yes there was a spike in CO2 due to volcanism and this was causing an extinction event according to one theory but there is little doubt about the role of the asteroid impact in the K-T event
That would indeed kill the dinosaurs in Mexico, but how could it kill the dinosaurs in say, China? Or Australia? And I'll thank you to not lecture me - I don't mind being enlightened and advised by a wise and knowledgeable individual, but not by someone who isn't either of those things.
Sorry but am i your personal researcher? Google is your friend and Wiki a great mate. Look up K-T extinction event But because you are uninformed enough to use a source like the one in the OP I will take pity. Read the section on how powerful that asteroid was estimated to be https://en.m.wikipedia.org/wiki/Chicxulub_crater
Do you recall what happened when that massive volcano erupted in Iceland? The ash and gases rose into the jet stream and were carried far and wide. Same thing happens with asteroid impacts and wildfires. The ash ends up blocking out sunlight and smothering plants. The volcanic ash also contains tiny silica shards that can cause internal bleeding in the lungs. Without breathable air or growing plants or even sunlight not many species can survive. The ones that did survive were mostly mammals who lived underground at that period in time. So it is a cascading series of events. Asteroid impact sets off earthquakes and volcanoes all around the world. Those volcanoes ignited wildfires and spewed toxic gases and ash clouds into the upper atmosphere where the jet stream dispersed them all over the planet. The clouds blocked out the sunlight causing plants to die and sudden drops in temperature. As @Bowerbird pointed out the K-T event evidence exists worldwide.
Give your advice to someone who needs it - I certainly don't, especially when the result will be urban myth (as is the 'dinosaurs were wiped out by an asteroid' drivel) and hearsay. Google is every wacko's friend too? The lesson here is - if you don't have an answer to question, tell the questioner to find it on Google.
There has been some research supporting gradual extinctions poor to KT event and it revolves around the activity of the Deccan traps. New research suggests they were active long before Kt and had been spewing massive amounts of co2 into the atmosphere
Confucius he say . . . ‘Make the lie big, make it simple, keep saying it, and eventually the suckers will believe it’. Confucius he also say . . . 'Do not follow the bovine herd – be of an independent mind.' Confucius he know what he talking about?
Agreed, gradual extinctions are just part of evolution as the environment changes and some species fail to adapt in order to survive. This occurred in the oceans long before any creatures and plants ventured onto dry land. (Or the water receded and they were forced to adapt to a drier environment.) The K-T extinction event was not a complete wipe out of all dinosaur species either since a few did survive. However they too were then forced to adapt to the changed environment that followed the K-T event. Almost all of the reptiles we have today prefer to live under rocks. Birds have evolved from dinosaurs that had the ability to flee from the disasters by flying. Interesting how sharks and crocodiles were largely unaffected since they were primarily sea creatures but the cooler temperatures did result in them adapting to become smaller and more efficient.
Let's just call it intuition? In the early days of the nonsense I asserted that an asteroid big enough to destroy all the dinosaurs on the planet would have been big enough to destroy the planet too. Shortly after that, it was announced the the asteroid was of normal size but kicked up so much dust it killed all the dinosaurs worldwide; after I asked 'So why didn't it kill all life as well as the dinosaurs?', it all went quiet. I actually believe they became extinct owing to illness or some kind of dinosaur plague.
Asteroids, floods, volcanoes, climate change... and how many other 'theories!' are presented with dogmatic certainty! So many really old people, or cosmic watchers, who were there and 'know!' what happened eons ago! But that is the new, 'Science!' of Progresso World. Whoever declares their opinion with the most certainty, conviction, and moral outrage must be right!
Pop science can sound dogmatic, but fundamentally science is quite the opposite. All theories are tentative and subject to change, and so do change constantly as new information becomes available.
Doesn't it seem at least probable that the asteroid triggered a number of other cataclysmic events like volcanic eruptions and other events listed in Post #3 plus acid rain, climate cooling caused by volcanic smoke, ash & other airborne particulates? After all, Krakatoa, alone, affected the whole world (1) so, imagine the effect that dozens of Krakatoas would have had on the atmosphere. (1) "Krakatoa eruption cooled the world" https://www.newscientist.com/article/mg18925385-000-krakatoa-eruption-cooled-the-world/ EXCERPT "WHEN the Indonesian volcano Krakatoa erupted in 1883, sending 25 cubic kilometres of rock and ash into the air, it did more than generate the loudest sound ever recorded. It also cooled the world’s oceans and suppressed rises in sea level for decades afterwards."CONTINUED
