He was an obvious slacker. He missed the unicorns and these lovely creatures too:

No Noah was NOT a slacker he did exactly what he was instructed to do, which is the reason why he was selected to build the ark in the first place.

There's not any growing body of evidence, just the same tired old group of diehard uniformitarian gradualists trying to head off their own intellectual extinction. :')

Quite the opposite, it's the same old tired Geologist and Astronomers who like playing with their computer models and taking trips to Cancun and being the darlings of the media who prop up what should have been a long dead hypothesis.

The impact hypothesis is easily falsified and debunked

Here's 10 reasons why the impact hypothesis fails right off the bat

1) Southern Hemisphere species were equally devastated as the Northern Hemisphere ones. This makes absolutely no sense. An asteroid hitting in the Northern Hemisphere should cause more devastation in the Northern Hemisphere.

2) Freshwater Species including amphibians (100% survival rate) did quite well. One only has to come to upstate NY to see the damage done to freshwater species by acid rain, Some lakes are completely dead. If the relatively tiny amount of acid rain put out by Midwestern plants can cause all that damage then the massive amounts of acid rain produced by a global nuclear winter would have had devastating effects all all freshwater species. That is not what we see.

3) Plankton

a)   Diatoms. The K-T event did not much affect the diatoms. Harwood (1988), based on studies from Seymour Island, eastern Antarctic Peninsula, the first to record siliceous microfossil assemblages across a K-T boundary sequence, notes that diatom survivorship across the K-T boundary was above 90 percent. Resting spores increase from 7 percent below to 35 percent across the K-T boundary.

b)  Dinoflagellates. Dinoflagellates also were little affected by the K-T event (Bujak and Williams, 1979). Brinkhuis and Zachariasse (1988) record no accelerated rates of extinction across the K-T boundary in Tunisia. Nor does Hultberg (1986) in Scandinavia. Danish dinoflagellates responded more by appearance of new species than by extinctions (Hansen, 1977), as did Seymour Island assemblages (Askin, 1988).

c) Yes other plankton did suffer massive extinctions but it wasn't because of the Asteroid or K-T event.

Marine calcareous microplankton, the coccolithophorids and planktonic foraminifera, were hit hardest of all by the K-T event. Thierstein (1981) proposes that the coccolithophorids extinctions were the most severe plankton extinction event in geologic history; via a "deconvolution" process, Thierstein (1981, 1982) reduced a Cretaceous-Tertiary "transition," in which Cretaceous assemblages were replaced by "new" Tertiary taxa, to an instantaneous catastrophe. Perch-Nielsen et al. (1982) note that the "catastrophic event"at the K-T boundary did not result in geologically instant extinction of the calcareous nannoplankton, and that most Cretaceous species survived the event. At DSDP Site 524, a sample above the K-T boundary contains 90 percent Cretaceous species. Isotopic analyses indicated that the Cretaceous species were not reworked specimens, but represented survivors of the K-T event that continued to reproduce in the earliest Tertiary oceans. The relict species became extinct some tens of thousands of years after K-T boundary time, probably via environmental stresses.

d) Antia and Cheng's (1970) work on survival times of phytoplankton species in complete darkness indicate that 1 month of complete blackout would produce 13 percent extinction, 3 months 68 percent extinction , and 6 months 81 percent. Thus, the 6 month to 1 year global blackout predicted by Wolbach et al. (1985) would have obliterated diatoms, dinoflagellate, and coccolithophorids precisely at the K-T boundary. A blackout event is not reflected in the algal record.

So please tell me how did photoplankton who depend on sunlight for their very exsistance not only not die out but actually thrive during a global blackout??

e) Another interesting thing about plankton, Microfossils were actually found in the Chicxulub crater itself!!! and even though they are essentially at "Ground Zero" they show no ill effects.

4) Reptiles would have suffered greatly if an Asteroid struck however they seem to have cruised through the K-T with no problems.

a)  Turtles  "The Hell Creek and Tullock formations contain many turtles, and span the Cretaceous-Tertiary boundary. Over 3000 specimens were counted on a modified minimum number basis from 510 localities. At least 15 of about 19 Cretaceous genera and subgenera survive into the Paleocene. The magnitude of the change in diversity is less than or comparable to examples within the Tertiary. These data do not support a unique comprehensive extinction at the end of the Cretaceous as postulated on the basis of Iridiurn concentrations."

My link is gone but the quote is from: Hutchison, JH. H., and J. D. Archibald. 1986. Diversity of turtles across the Cretaceous/Tertiary boundary in northeastern Montana. Palaeogeography, Palaeoclimatology, Palaeoecology 55:1-22.

b) The four crocidilian families survived seemingly unaffected through the K-T boundary.

Most notable is the American Alligator whose ancestors were living at the time of Cretaceous right at ground zero

This is the skull of an extinct animal closely related to living crocodylians (U.S. National Museum 22039). It comes from the middle Cretaceous (roughly 100 million years ago) of central Texas. It shows the occlusal pattern seen in the common ancestor of alligators and crocodiles.

So they were there!

Even forgetting about the implausibility of Alligators who are very cold sensitive surviving a nuclear winter, How did they survive the blast and the follow up tsunami an Asteroid would have caused?

5) Tropical Honeybees also would have been wiped out immediately under the impact scenario. They survived unscathed.

6) Dinosaurs

a) Dinosaurs were living near the poles so they were capable of surviving cold temps, So if other animals could survive a global nuclear winter why couldn't they?

b)  Dinosaurs were slowly going extinct before the K-T event and probably most of them were gone by it.

Sullivan (1987) For the 19 dinosaurian families (33 to 39 species) existing in the last 20 million years of the Cretaceous, most disappeared before K-T boundary time, and eight at the K-T boundary. The eight families are represented by 12 species in the final 3 million year of the Cretaceous, and most of the species by only a few specimens (two to 10, average 5.7).

c) Few dino fossils are found in the K-T boundary. Fossilization maybe a rare process mostly due to scavengers scattering the bones. However if an Asteroid strike instantly wiped out the dinosaurs than there would have been too many dead bodies for even the scavengers to get them all, so their should be large amounts of fossils in the K-T boundary 

d) Actually there is evidence that some dinosaurs made it into the Tertiary.  

e) One group of Dinosaurs did make it and lives to this very day, We call them Birds.

7) The Thin Layer of Iridium:

That "Thin" layer of iridium as it is described represents 10,000-100,000 years of sediment. How on Earth could iridium (a heavy metal no less) stay up in the atmosphere that long? It would at most wash out within months if not weeks or days.

8) Iridium spikes aren't uncommon:

      a) Notice the larger than the KT iridium spike way later in the Paleocene (on the upper right side)

Now, If a 10 mile wide Asteroid caused the IR Spike for the KT-Boundary. How many more time larger would an Asteroid have to be to cause that bigger spike later on? How come that one didn't cause mass extinctions?

b) There are multiple Iridium at some locations

For example, Lattengebirge, Bavarian Alps, has three iridium anomalies, below, at, and above, the K-T boundary (Graup and Spettel, 1989). The oldest anomaly antedates the K-T boundary by 14,000-9,000 years. To which of these anomalies might the Rocky Mountain (and other) "K-T boundary" iridium spike be isochronous, if any? The Brazos River, Texas, locality has two iridium spikes, one at the K-T boundary, and one below (Ganapathy et al., 1981). At Gubbio, Italy, both the iridium and shocked minerals do not occur as a sharp K-T spike; enrichment begins 2 m below the boundary and extends 2 m above it for a total of about 400,000 years (Crockett et al, 1988; Rocchia et al., 1989)

8) Volcanos can also produce Iridium spikes.

For example the 1783 Lakigigar eruption produced an 18-fold iridium enrichment in the ice cores of Greenland which is well within the range of the iridium spikes of the K-T event. So volcanic activity can produce iridium spikes and boy was there monstrous volcanic activity during the KT. The Deccan traps of India and Pakistan- (covering 500,000 sq. km and up to 2 km thick) , southern Brazil , western U.S, etc which was more than enough to produce the iridium spikes. Plus the volcanic activity unlike a one shot asteroid lasted a long time so it could have been laying down iridium over 10,000-100,000 years. Koeberl (1989) also reports iridium concentrations up to 7.5 ppb in volcanic dust bands in blue ice fields from Antarctica.

9) Iridium is missing from the Chicxulub crater itself!!!!! 

How can an Asteroid or whatever (It's still not proven to be a meteor crater and it's looking like one less and less) that caused the Chicxulub crater produce a iridium spike around the world when it didn't contain iridium?  

10) Arsenic, antimony, and selenium levels are very high in the K-T Boundary, These elements are rare in meteorites (but not in volcanoes).  

None of these makes sense under the impact hypothesis

And speaking of "trying to head off their own intellectual extinction"

See the link I posted about how Iridium is missing from the Chicxulub crater itself!!!!! 

Now the evidence this guy found clearly overwhelmingly debunks the Asteroid theory, yet this guy blatantly just dismisses it.

Quote right from the conclusion in the paper

"If we exclude the extremely implausible assumption that the K/T boundary is not related to the Chicxulub impact event",

Like Hey!!!, who says you can do that? You can't just exclude conclusions because you don't like it. That's piss poor science at it's worst.

Here's another example of Pro-Asteroid scientist playing tricks  to hold on to their trips to Cancun.

LOL!!!! and I thought the creationist were bad

Recap

YOU: A post of insults directed at paleontologist and links to post where you insult more paleontologist. No Evidence

ME: Evidence with supporting links

YOU: More insults, still no evidence

I think it's clear who doesn't know what he is talking about

I highly suggest you do some reading on the subject, my post (what you call spam, which is funny considering I never posted to you before and your post consist of nothing but insults) is only the tip of the iceberg, it's pretty clear you are uninformed in this matter, at the very least you might come up with a better argument than "paleontologist are stupid"

Your pile of links lead to articles which show that the impact model works and that NOTHING ELSE DOES. You use those to conclude that the impact either didn't happen at all (which seems to have been your take on it in earlier versions of your spam) or that it didn't have any effect, IOW, the same non-argument, i.e., that the extinctions were happening anyway and the impact timing was just a huge coincidence.

Regarding those paleontologists -- they are just regurgitating the same untenable arguments they've used since the Alvarez hypothesis emerged almost thirty years ago. They've literally done nothing but harp on what they already believe (which is what you're doing here, and have done on a number of other threads.

Obviously you don't know what you're talking about.

I've been reading an artical in SciAm on mass extinctions. The K/T extinction was evidently very quick (on the order of weeks) whereas earlier extinctions, such as the great Permian die-off were on the order of several thousand years. Researchers arrived at this conclusion through several converging lines of research, including analysis of fossil spores and pollen grains, and of the various chemical residues left by long-dead unicellular life.

It's a fascinating read, but may be a bit dry for most folks.

He did save some, but since reptiles grow each year, and with the vapor canopy gone with the rain, cosmic rays entering the earth's atmosphere ended the long life spans of people and plants and animals.

So, the Dinosaurs didn't grow as big anymore, and they either died off or were eaten.

Besides, most dinosaurs were small animals anyways.

Your pile of links lead to articles which show that the impact model works and that NOTHING ELSE DOES.

Really?

I'd like to know how tropical bees, alligators, amphibians, turtles etc. survived when they would be the 1st to go supports an impact model?

I have to go with Norman Macleod, Quote "The impact theory says in effect that a rock fell out of the sky and killed everything, except for the things that it didn't kill. I don't think that's much of an explanation".

Or how the iridium layer worldwide doesn't match up in concentrations and/or time frame with each other supports a single impact.

And as for some of my links mentioning the impact, well duh, the impact hypothesis is the most famous one right now, so what ever evidence comes along they are going to see if it fits, often trying to shoehorn it in with crazy ideas like more and more impacts (This guy is up to 5 already, *sigh* more & more Epicycles) instead of going with obvious in that the Chicxulub crater had nothing to do with the mass extinction.

You use those to conclude that the impact either didn't happen at all (which seems to have been your take on it in earlier versions of your spam) or that it didn't have any effect, IOW, the same non-argument, i.e., that the extinctions were happening anyway...

All the evidence shows many types of animals/plants including the dinosaurs were in fact disappearing well before the K-T event.

I could spam (which I guess in your dictionary Spam means any evidence you can't refute) you with tons of evidence, but here's just one.

Now, please provide evidence that the diversity of life was unchanged from the late Cretaceous right up to the K-T event.

I won't hold my breath.

and the impact timing was just a huge coincidence.

Let's see

There's been impacts as big if not bigger than Chicxulub before & after and they didn't cause any mass extinctions
There's been massive volcanic eruptions like the Deccan traps before and they have caused mass extinctions.

which is more plausible?  

Regarding those paleontologists -- they are just regurgitating the same untenable arguments they've used since the Alvarez hypothesis emerged almost thirty years ago. They've literally done nothing but harp on what they already believe (which is what you're doing here, and have done on a number of other threads.

Another childish rant, yawn, yawn, yawn.

It's very telling when you have to resort to personal attacks, about who has the evidence and who doesn't

Obviously you don't know what you're talking about.

Actually you look silly, if you actually read the article the scientist you are ranting and raving against is Gerta Keller. She actually believes there was an impact so she's actually leaning towards you side. She just doesn't think it was Chicxulub and has more than enough evidence to prove it, unless you care to show how worms & crabs were able to burrow along like nothing happened during a meteor impact/tidal wave

qam1: "See the link I posted about how Iridium is missing from the Chicxulub crater itself!!!!!" http://www.lpi.usra.edu/meetings/lpsc2003/pdf/1811.pdf

"On the other hand, the globally distributed fall out material at the K/T boundary has high PGE concentrations indicating that the Chicxulub impactor was most probably a C-chondritic asteroid."

Now that's poor science, they start with a predetermined conclusion and try to make the evidence fit where it doesn't, which is why they have to follow up with the silly

If we exclude the extremely implausible assumption that the K/T boundary is not related to the Chicxulub impact event,

Now if the conclusion was clear that the K/T boundary is related to the Chicxulub impact event then why would they even have to state that? Outside of Creationist literature where have you seen anything like that?

The reason they put that in there is because clearly they find the K/T boundary is not related to the Chicxulub impact event but they don't want that to upset their preconceived notions, so they come up with wild speculations instead.

And that's all it is, because what they fail to explain in their wild guesses (either ignorantly or deliberately) is how come at other similar impact sites Iridium and other PGEs are found as expected (i.e. Mistastin, Barringer, Sudbury) but somehow the meteor that caused Chicxulub left Iridium traces 1000s of miles away (and in some cases 1000s of years later) but none at the impact site.
