Dino death: Asteroid impact more likely than volcanoes, new study says

Asteroid impact, not volcanoes, made the Earth uninhabitable for dinosaurs

The idea certainly isn’t new but they offer some new analyses and information:

The asteroid, which struck the Earth off the coast of Mexico at the end of the Cretaceous era 66 million years ago, has long been believed to be the cause of the demise of all dinosaur species except those that became birds.

However, some researchers have suggested that tens of thousands of years of large volcanic eruptions may have been the actual cause of the extinction event, which also killed off almost 75% of life on Earth.

Now, a research team from Imperial College London, the University of Bristol and University College London has shown that only the asteroid impact could have created conditions that were unfavourable for dinosaurs across the globe.

They also show that the massive volcanism could also have helped life recover from the asteroid strike in the long term. Their results are published today in Proceedings of the National Academy of Sciences.

    This again? If a catastrophe caused the end of the dinosaurs then we would expect to see the fossils going up to, through and then just on top of that layer. We don’t see that.

    Impact/s associated w/ mass dino die off/s aligns best w/ creation science and scriptural testimony, as explained in by the YeC Moshe Emes series and framework volume I where we find the 1656 anno-mundi ‘Mabul year’ aka global flood by Noach, begins by the original single continent and ends by the onset of The Ice ages. so the dinos thrived for 1656 years, so that requires ID of 10+/- founding dino kinds w/ the designed in capacity to adapt and specie-ate. Thus we are left w/ those dino-species better known as reptiles.. dinos that lost info., so whose bottleneck founders and could survive outside the ark. So the dino die-off and associated impacts ended by 4k not 65M rounded down years ago. (The ice ages ending about 3800 rounded years ago and Ancient Egypt founded not long thereafter, about one Sothic cycle (1400 years rounded down) more recently than the current consensus). Like Stephan C. notes, the impact/s link to hyper tectonic action and volcanic activity..

    The fossils do in fact go right up to the layer (hough gradually diminishing somewhat perhaps due to volcanism . Then (since 75% of all life was destroyed) they are absent from the impact layer, then they very slowly resume above it as life gradually recovers, but with a very different population due to the mass extinction.

    Please don’t cloud the issue with facts. πŸ™‚

    Please explain how, if a catastrophe killed off all the dinosaurs in the process of destroying most of the biomass on the surface including the bodies of the dead, how the thin catastrophe (impact) layer would still contain a lot of dinosaur fossils. And how the layer immediately above the catastrophe layer would still contain an undiminished population of dinosaur fossils.

    Wow- your fantasy is not reality. If it destroyed the bodies of the dead then nothing would have survived. The gators and crocs would have been history.

    Do you have any reference to what you are saying? Any reference?

    If a catastrophe killed off the dinosaurs then the bodies would remain to leave fossils. The scenario promoted is that most dinosaurs died from starvation after the event. Those would be in and on top of the kill layer.
