haha, you guys are a scream, don’t tell me you are too lazy to press buttons.

Here is a quote, then there follows a link or two.

Neither the quote nor link was my original source as far as I remember but the facts point to it being one of their research papers published by the Geological Society. Or it may be another, independent research group, I really could not say…

What Keller and colleagues have done is to de-amalgamate the late Maastrichtian stratigraphic record. Their work indicates that the Chicxulub impact occurred a good 300,000 years before the K-T boundary. They show from several localities in Mexico that there is about 4 - 9 meters of sediment above the impact layer that are not tsunami deposits but which have been deposited gradually over a time period of 300,000 years. The K-T boundary lies above this sediment layer. Fauna in this intervening sediment layer i.e the one that lies above the impact layer and below the K-T boundary shows no signs of stress. Species found below the impact layers are found above it too with no noticeable loss of biodiversity. Keller interprets this to mean that the impact did not cause serious environmental stresses and mass extinctions.

No. We merely expect you to behave correctly when asked for a reference.

Thank you for the links. The second actually gives the correct reference: Journal of the Geological Society, Vol. 166, 2009, Keller et al “New evidence concerning the age and biotic effects of the Chicxulub impact in NE Mexico”

You will of course note that Dr Keller and her colleagues are of the opinion that the K-T extinction was caused by the eruption of the Deccan Traps.

oh, I see… scientist obedience class … behave scientist, behave!

Dr. Keller is probably wrong about the Deccan Traps. That does not matter at all, everyone is wrong about something. Most believe the iridium layer is directly connected in some way to the global extinction event and the extinction of the dinosaurs, as the dinos fossils were found below the 2-10cm layer of iridium rock but were not found above it. As I said before about the Deccan Traps not being the source of iridium at the KT boundary because there is no iridium in the basalt of the Deccan Traps.

When asked for a reference you refused, then you told people they were too lazy to look for themselves, then you admitted you couldn’t even remember your original source or even who headed up the research.

Now you proclaim that Dr. Keller is probably wrong. Based on what? The back of a cornflake packet? A couple of casual minutes on google? Your years of training and expertise in the geosciences?

What was Keller’s response when you told her she is probably wrong? I’ve got her email address at Princeton if you want (you can find it on google unless, in your words, “you are too lazy to press buttons”).

Go ahead, email her, I’d love to know what she says. Ask her if there is iridium in the Deccan Traps. Thanks!

You’re too lazy to do it, you don’t have the courage, or you’re a CIA operative and can’t break your cover?

How does this help your case that humans and dinosaurs once lived together?

We are just feeling our way towards something like that. Whether we can get there at all is another question. But already we’ve learned something new, that you no longer know how the dinosaurs died.

There are some who will look to connect the dots as they are found and those that will not.

I think there’s still quite a bit of scientific debate, and a lack of clear proof, of exactly how the K-T extinction unfolded, and how the dinosaurs died. But this has no effect on knowledge of WHEN they died. Even at ~65 million years ago give or take 300,000, there’s no question it didn’t overlap the human fossil record.
 
If that leaf fossil (#80) was in more than one layer of “time”, how can that be explained? What about multi-strata tree fossils? I’ve never heard an explanation of that. What if science is like your run of the mill anti-catholic that despite the one piece of evidence that disrupts his views, he follows on in the same course, ignoring what would negate his belief structure?
So…
If there is a single fossil of man with dinosaur, what then?
If there are examples of man-made items in coal deposits, what then?

After all, we’ve learned that ancient Egyptians had batteries (of a fashion), and light bulbs. Science is “evolving” all the time.

Better to say, scientist politeness class.

Dr Keller’s point is that she found enough pre-K-T species above the iridium layer to indicate that the layer itself did not mark the actual extinction. She agrees that the Deccan Traps are not the source of the iridium, but since - from her perspective - the iridium layer is 300,000 years before the big extinction, then the presence or not of iridium in the Deccan Traps is irrelevant.

I find diagrams are helpful sometimes.

---- 13 species found after KT boundary (=> KT boundary represents an extinction event) (dinosaurs dead!)
---- KT boundary extinction event/iridium layer, (300,000 years after the Chicxulub impact)
---- 44 species found before KT boundary (dinosaurs alive!)​

---- 52 species found on site after meteor impact (meteor impact was not an extinction event)
… Chicxulub impact
---- 52 species found on site before meteor impact​

Science presupposes the trustworthy, intelligent structure of matter, the ‘design’ of creation.”

I was not sure from where you got this idea or quote, but it is really great.

Thanks!
