It’s no great feat to find a couple of exceptions.

It seems everything is an exception

The fact remains: land animals suffered extinctions during this event at several times the rate of water animals.

Name one thing that went extinct during this event?

This so called event happened 13,000 years ago

Woolly Mammoths went extinct 11,500 years ago
Sabertooth cats went extinct 9,500
Columbia Mammoths 9,500
Megatherium 8,000
Dire Wolves 4,000
ect, ect

It looks like they are making the data fit their model just like the AGW people do.

By logic of this study, Anything that goes extinct in Siberia for the next 5000 years up until the year 6903 will be because of the Tunguska event that happened in 1903.

Wow, looks like a lot of the same wheels turning in the same ruts, again.

Some raging nimrod added “piltdownman” to the keywords.

If it makes anyone feel any better, this scenario — which involves bombardment of the Earth by various waves of particles and objects, different sizes and energies, with the waves separated by either hundreds or thousands of years, and originating in a relatively nearby star which went kaboom — is catching on some, but, as with the Alvarez model for dino extinction via an impact at the K-T boundary, has met with furious resistance.

Not Chicago, Mistassini Quebec.
PS: Part of Hudson Bay is a pretty large crater too...
Lake Mistassini might be a remnant of the comet impact (including the large depression to the southeast)

A quick calibration question for you:

How many galaxies could Moses see?

" it doesn’t even qualify as science, and that includes what we hear coming out of the space program unfortunately."

The babble generated by your self-imposed ignorance is astounding. Are you even aware of the wealth of on-the surface Mars photos that have been generated and returned to Earth by the Mars Rovers over the past five years?

Why do people need evidence? We're supposed to take the facts laid out in the Bible on faith, not fact. That's what wrong with this world, there is no faith anymore.

But since there is no faith, and people need to see before they believe

It's "studies" like this that give Creationist ammo against all science

You would think the authors would have at the very least check when exactly these animals actually went extinct before proclaiming that a comet wiped them out 1000's of years before they really did die out.

If it makes anyone feel any better, this scenario — which involves bombardment of the Earth by various waves of particles and objects, different sizes and energies, with the waves separated by either hundreds or thousands of years, and originating in a relatively nearby star which went kaboom —

More and more Epicycles!!!!!!!!!

is catching on some, but, as with the Alvarez model for dino extinction via an impact at the K-T boundary, has met with furious resistance.

Megafaunal extinctions followed human arrival in Australia, North America, New Guinea, Madagascar and South America.

Now which makes more sense?

A) Human predation and maybe diseases slowly drove these species to extinction

or

B) Coincidentally, where ever humans arrived, comets/asteroids then began to hit where these new humans were and over 100 to 1000s of years they bombarded the area, leaving no trace, but they somehow killed one or two species off at a time (while apparently leaving the others unscathed) until they were all gone.

On second thought, here's your answer.

I really don't expect you to be intelligent (or intellectually honest) enough to answer mine satisfactorily...

http://www.creationscience.com/onlinebook/index.html

I am already familiar with Brown's book, and have researched parts of it many times. It is a loose-knit collection of nonsense that satisfies only those who either know nothing or are already believers. Scientific evidence it is not.

Here is one example that I have researched. He says:

This new atomic accelerator technique has consistently detected at least small amounts of carbon-14 in every organic specimen—even materials that evolutionists claim are millions of years old, such as coal. This small, consistent amount is found so often among various specimens that contamination can probably be ruled out. Ancient human skeletons, when dated by this new “accelerator mass spectrometer” technique, give surprisingly recent dates. In one study of eleven sets of ancient human bones, all were dated at about 5,000 radiocarbon years or less!

This is clearly wrong. I have the study he is referring to in my office (Taylor et al. 1985).

The Taylor et al. study examined eleven skeletons that were claimed to have some antiquity, up to 70,000 years, on the basis of an experimental dating technique called amino acid racemization (AAR). Those old dates did not fit the archaeological context (most samples were from Southern California). What Taylor did was reexamine those skeletons with a new form of radiocarbon dating called accellerator mass spectrometry (AMS). He found that they weren't ancient at all; none dated older than 11,000 years. That fit the archaeological context and exposed the inaccuracies in AAR.

When Brown makes a big deal about the "residual" carbon 14 in these "ancient" skeletons he makes a fundamental error: the skeletons aren't really ancient! And the study he (sometimes) cites shows it! Whoops!

Nowhere does this study cast doubt on the accuracy of radiocarbon dating. Rather Brown's use of this study in this way casts doubt on the accuracy of his research. And this error has been in his various editions since at least 1989.

Another error: the Calaveras skull. No serious archaeologist considers this to be ancient. Flowstone can be pretty quick moving in an active cave. When Brown claims this skull was "130 feet below ground" he neglects to mention it was found in a limestone cavern, and not under 130 feet of rock. Whoops!

Sorry, I'm not impressed by Brown's book, nor by the quality of his research.

Care to try again?

Thanks for the ping. The carbon layer is a very interesting find. It is evidence of massive incineration covering a large area of North America. That it was caused by the atmospheric explosion of a comet or asteroid is a reasonable theory.
