Dinosaur Extinction: After the Impact? (1 of 2)

65 million years ago a comet or asteroid impacted the earth and brought the age of the dinosaurs to an end. But, was that reall what happened? Profs. Gerta Keller and Wolfgang Stinnesbeck deconstruct the evidence to find out what really killed the dinosaurs, tonight on The Urban Mystic Show.

00.46 you meant to say was roghly 2011 years ago they died the astroid hit earth just the second jesus was born

@milo78910112020moshi If your ass was near my foot I would kick it.

The amount of sulfur released by the impact has been calculated. The rock the asteroid impacted was not only carbonate, but also anhydrite and gypsum, both S-bearing minerals. These comprised up to 63% of the rock.

There actually was quite a lot of sulfur present.

@Lingula77 There's the beginning of a debate somewhere here but I just don't have the time right now. You stumped me for now. Not many people can actually say that. I like when people keep me on my toes, I just appreciate it when they keep up to date on what they're debating me on.

Let us find another cause. Leave the meteor behind. There is a lot of possibility.

The answer to what killed the dinosaurs is obvious....... Q: Where do we find the remains of the all of the dinosaurs? A: In water deposited sedimentary rocks along with all of the other fossils around the world. Noah's flood destroyed them all around 4400 years ago.

@wpaxton That's OK, I just wanted to correct some things about which there is little debate. I've read a lot of articles about this subject so I can point you to the original sources, including those by Keller, Stinnesbeck and Adatte. There was a review in Science two months ago (5th of march), but it argues the opposite of what you're claiming in these two videos so perhaps you're not interested in that. I haven't seen a response from Keller yet.

[Lingula77]

@wpaxton But you do assume it impacted in the 'very same spot' and you say that the impact 'is said to have created a megatsunami', so you're talking about a past impact, not a hypothetical one. As it is now, you're not making clear that the real asteroid did impact in a shallow ocean, which could produce both a tsunami and ejecta.

Also, at 7:10, you confuse volcanic ash (silica) with ash from burning vegetation (carbon). The ash layer at the K-T boundary is not volcanic ash.

@Lingula77 I'm not talking about the real crater, I'm talking about a fictional movie that has a comet hit inland mexico and says there was a tsunami even though the fictional impact was nowhere near the water. The first ten minutes of this video is a movie review, the next nine deals with Keller & Stinnesbeck's theory.

@wpaxton I'm not really sure what you're talking about. The location of the Chicxulub crater was published in 1990 by Hildebrand et al in Geology. It's located at about 22.6 degrees N and 89.5 degrees W (my estimate). You can't see the crater on satellite photos; it's buried. The red circle in your video is clearly in the wrong place.
