RSF: Remember the Nautiloids!

This is the show from Sunday, March 23rd 2012.

SUMMARY:



* The Latest Creation Magazine and Round Four of the Debate: Real Science Friday co-hosts Fred Williams and Bob Enyart discuss great science news from the Spring 2012 edition of Creation magazine including on:
- Astronomers shocked that the Sun and Earth are made from different oxygen.
- Evolutionists take Hawking's warning about angry aliens increasingly seriously.
- Just add water to the list of the fine-tuning properties in the universe.
- While engineers typically can look at the parts of a newly-invented machine (say, a new kind of mobile device) and predict it's form and function, but this is not true of anything possessing emergent properties (like water which arises from hydrogen and oxygen); and what is truly astounding is the emergent properties in living cells which, while often compared to computers and machines, in reality make use of computers and millions of machines but are qualitatively very different than either a machine or a computer.
- Round Four of Bob's debate with atheist AronRa serves up ice-cream cone shaped fossils, millions of them, that falsify Aron's claim that at the Grand Canyon there is "no indication of rapid stratification."

* Excerpt from Debate: At the Grand Canyon, "There is no indication of rapid stratification…" -AronRa

Bob Enyart: Millions of Nautiloids: [from Bob's Round Four debate post] Aron, in the canyon there is a single seven-foot-thick (on average) layer of limestone that runs the 277 miles of the canyon (and beyond) that covers many hundreds of square miles which contains an average of one nautiloid fossil per square meter.

Many of these nautiloids are larger than your arm, with fossils of tens of millions of these creatures that were buried in an extremely rapid event that killed them all, thus forming yet another important layer of the canyon's walls. Along with many other dead creatures in this one particular limestone layer, 15% of these nautiloids were killed and then fossilized standing on their heads. Yes, vertically. They were caught in such an intense and rapid catastrophic flow that gravity was not able to cause all of their dead carcasses to fall over on their sides.

I have interviewed the scientist who discovered the mass burial site. He has worked in the canyon at the invitation of the U.S. National Park Service, and is the world's leading expert on nautiloid fossils. As is true of many of the world's mass fossil graveyards, this massive nautiloid deposition provides indisputable proof of the extremely rapid formation of a significant layer of limestone near the bottom of the canyon, a layer like the others we've been told about, that allegedly formed at the bottom of a calm and placid sea with slow and gradual sedimentation. But a million nautiloids standing on their heads would beg to differ.

Anyone should be able to agree that this is what is considered hard evidence of rapid stratification.

Aron, you don't try to hide your disdain of creationists. But just in case you or any of our readers are interested in learning about the discovery of this mass nautiloid graveyard and just in case you can stomach listening to a creationist geologist (the very researcher who's work caused Yellowstone Nat'l Park to remove their erroneous exhibit sign that showed a false in situ interpretation of their petrified trees, none of which had root systems), (Find this here if this embedded video doesn't work.

Can we get a citation to the scientific literature to Pastor Bob's nautilus canyon that apparently dooms not only evolution but physics and astronomy as well? thanks ever so much.

Is there anyone who would disagree that a single layer could be laid down quickly? I interpret AronRa's statement as meaning that you couldn't have lots of layers being laid down rapidly (as the creationists would claim).

Sounds like this seven-foot thick layer of nautiloids is proof against a claim that no one has tried to make.

The problem is, it's like this with pretty much every fossil deposit. Dead animals don't just lay there for millions of years waiting for the weather to eventually cover them up. They're either buried rapidly and fossilize, or they get eaten by scavengers, or they just rot away. And we find stuff like entire herds of brachiosauri. What kind of flood is going to sweep a group of creatures like that off their feet and bury them in sediment against a mountainside? Something pretty massive, if you ask me.

I looked quickly at that but saw no reference to the literature nor any mention of the name of the person who did the work, just Pastor Bob's hearsay comments. Since I do not trust the good man of god to understand the science, or on those occasions when he does to be honest, I would like a real reference.

Against a mountainside? It wasn't a mountainside at the time, it was the sea floor. Yes, floods happen, they sweep out lots of mud which buries the creatures, and they eventually fossilize.

As AronRa correctly pointed out, stuff within one layer gets buried all at once, but you don't have more than one layer at a time. Sounds like it was a pretty big event that buried all these nautiloids, but it is just one of the many many layers that the Grand Canyon has exposed.

The Institute of Creation Research's Steve Austin found the fossils. But is this discovery really strong evidence in favor of the flood, or is it actually validation of the standard 'deep time' geological model? Let's see....

Bob points out that conventional geology was not aware of the existence of this particular group of fossils in Grand Canyon Redwall until Steve Austin found them, which may be true. What the conventional model claims is that the Redwall limestones were laid down approximately 330 to 300 million years ago, and that rocks may be identified and relatively dated using the fossils that are found within them. The evolutionary/geological assumption is that specific assemblages represent samples of specific ecosystems that change over time, reflecting evolutionary change as well as the different environments at the time of deposition.

Here's an interesting paper from the 1950s presented at a conference of the New Mexico Geological Society, identifying other classic biostratigraphical marker fossils of the Mississippian subperiod when the Redwall was laid down, including crinoids and brachiopods. This agrees with Steve Austin/Bob Enyart's interpretation that Nautiloids had not (at least not when this paper had been written) been found in the Redwall. However Nautiloids were common fossils in other Mississippian deposits elsewhere, and can be considered to be an index fossil of the marine ecosystem 300 million years ago. In fact, if you look up the details on the Nautiloid that Steve Austin found in the GC, the wikipedia entry reads:
Rayonnoceras is an extinct cephalopod genus that lived around 325 million years ago during the Carboniferous (late Mississippian)...
...which I can't help but notice falls squarely in the middle of the time period estimated as the age for the Redwall limestone.

Therefore, Austin's discovery is actually a triumphal validation of the conventional geological model of deep time, and the idea that different assemblages can represent ecosystems separated by time and evolution.

so I take it there is no Austin paper in the scientific literature? And the point that conventional geology was unaware of these fossils until Austin found them is what? Science finds new things all the time.

But now claiming that Austin's find really supports standard geology is inappropriate. Read your Bible, believe your Bible. Make the nautiloids fit with the Flood. there, wasn't that better.

Global?

The fact that there was a major flood at some point in the past, when the area around the Grand Canyon was the sea floor, doesn't give any indication that this flood was global. Where'd you get that from?

Also, if there was one Great Flood, and it was responsible for this one layer, then when did all the other layers get laid down?

You think a flood buried the nautiloids? :AMR:

A flood ... under the ocean?!

Also, if there was one Great Flood, and it was responsible for this one layer, then when did all the other layers get laid down?
It's all one big layer that was sorted by the one event.

they get the one great world wide flood from the oral history of shepherds as written down and translated into the Holy Bible. You need to pay more attention in class.

Ah the magic sorting. Like the Harry Potter sorting hat?

Tell us Stripe-o what killed the nautiloids? How did they get stuck in all that rock?

They probably decided it was best for them to do so rather than risk having to put up with your stupidity. :)

So no answer as to how all those nautiloids got stuck in the rock. Typical. but I am supposed to buy into your analysis based on the oral history of shepherds so I don't go to the hell that your omnipotent magic sky person made.
Okey dokey. Let us know when you wish to contribute something of substance to the discussion with a rational basis.
