Sort of like a Pit Tyrannosaurus? Or a Rexweiller?

I'm having some trouble with the image of the momma rex climbing into the nest with all the baby rex eggs and then, you know, sitting down.

Possible titles for the video:

(1) Honey, I Squashed the Kids!
{2} Guess Who's Coming to Breakfast?

They get the hips so well all can get the brains!

It's more than hips. We birth early and the bulk of brain development occurs outside the mother's body. Stimulation by lights, sounds and adults while the brain is growing must have huge implications for intelligence.

The soft skull, cartilaginous fingers, reduced jaw, and underdeveloped lungs indicate the human infants are born "prematurely" compared to the other primates. To reach an equivalent stage, humans would have to have a gestation of about 18-20 months.

P.S., Oxygen doesn't burn. I take it's been a long time since you took Chemistry.

I think the point is that if the specimin has been protected against oxygen, the soft tissue could be preserved. As with insects in amber.

I actually know the researcher who discovered the fossilized soft tissue.

Interesting. You say that the researcher found 'fossilized soft tissue'? If I read the story right it (the material inside the bone) was NOT fossilized. Isn't fossilization when the original organic material is replaced with minerals? Looks to me like the original material is remaining.

Is anyone else waiting to see a rib turn into a woman?
Excuse me, but isn't it a proven medical fact that men have one fewer rib bones than a woman?

No. For the same reason if you lost a finger, your children would still be born with ten fingers.

To my knowledge, they haven't yet conducted the research to uncover precisely what are the molecules of these structures (whether they consist of the original organic components or whether their structures have been preserved by some method akin to mineralization). What they did do is chemically dissolve the minerals from the structure, which resulted in the bone matrix material that they've been studying. They've since duplicated the process with several other dinosaur specimens, so this actually challenges the entire concept of how organic specimens become fossilized (the prevailing view had been that you're left with nothing but minerals).

BTW, I asked exactly that question myself and that's basically the answer I got.

I used to know a guy who worked with plant fossils; he claimed that the protoplasm in plant cells was replaced by minerals but the cell walls generally were intact. He had lots of slides (microscope, not 35mm) of old ferns and palms which looked just like a slide from a living plant. He used the vascular structure to build the tree family tree from the fossil trees.

So birds are related to dinosaurs. We're the same species as Janet Reno.

Is it too late to join the dinosaur clan?

I guess we can inject some frog DNA up Jurassic. Ooh-that's not rated PG. Sorry.

So it's a fossilized non-fossil.
Or is it a non-fossilized fossil.

"Well, seeing that it was found in a 70 million year-old bone, how old could it be?"

Oh, yes, I forgot, the found the death certificate right next to the bones.

"IIRC, the YEC crowd has this novel notion that C14 dating is perfectly accurate right up to 6-10,000 years ago, and then suddenly becomes utterly bogus."

Actually, many YEC's believe that C14 dating is completely accurate, as long as you account for changes in the C14 ratio in the biosphere. For example, approximately 4,500 years ago, the flood drastically changed that ratio.

The C14 ratio in the environment is governed by (a) the amount of carbon in the biosphere, and (b) the amount of C14 generated in the atmosphre.

(b) remains relatively constant. However, the flood (as evidenced by the geologic column) drastically altered (a), removing a lot of carbon from the biosphere. Therefore, the C14 ratio pre-flood would have been much smaller than the C14 ratio post-flood. Therefore, measuring based on current C14 assumptions would yield older dates for things buried before and during the flood. When you adjust C14 dates to take this into account, many YECs maintain that the results are accurate to the biblical timeline.

Criticisms like this get tiresome. If you've been on these threads for any amount of time, you've seen the mountains of evidence for the various dating methods. You don't accept them? Fine. Provide some evidence from a peer-reviewed source refuting the evidence.

Some scientific facts are so heavily supported by the evidence that it is a waste of everyone's time to keep discussing them.

They will ultra-miniaturize & "bonsai" them (down to, say 100-150 pounds, with bug eyes and a puggish snout) for the pet trade.

You'd probably want one of the pack hunters instead of a lone hunter like T-Rex. The social instinct is one of the reasons why you can have a 150 pound pet dog but not a 150 pound pet cat. Social animals are much less likely to decide to eat members of their pack.

There's a really simple explanation: those bones are probably eight or ten thousand years old.

Please provide some evidence for this claim.

hrmn...

sounds rather silly on the face of it, but, for once, the YEC's have come up with a testable hypothesis.

1. have you (or they) ever tried to wash the carbon into or out of organic matter using water? Do you (or they) understand the problem with the notion that one can use water to wash carbon atoms -let alone specifically just the radioisotopes- into or out of the organic chemical molecular compounds of which flesh and bone are composed?
This rather dubious capacity of water is required to explain the gradation of C14 content in the fossil record - otherwise, all the fossils supposedly laid down by the flood would date out to be about the same age, uniformly much, MUCH older than 4,500 years.

2. Carbon enters the food chain (and, thus, into animal tissues) principally through the photosynthesis performed by plants and photosynthetic algae and bacteria, converting atmospheric CO2 and nutrients leached from the soil into organic (carbon-based) compounds and free atmospheric oxygen.
How, exactly, would precipitation of any volume, type, or duration selectively scrub out the free atmospheric non-radioisotopic CO2, leaving CO2 containing C14 alone?
This rather dubious capacity of precipitation is required by the assertion that "...account for changes in the C14 ratio in the biosphere. For example, approximately 4,500 years ago, the flood drastically changed that ratio."

3. If indeed the flood "changed the ratio" of C14-bearing CO2:mundane CO2, by removing mundane CO2 from the atmosphere, then by comparing the supposed time of this notional event to the oldest dates one can establish through C14 dating it seems to me that the composition of the atmosphere was radically different.
a.4,500 years is roughly 1/11th of the useful range of C14 dating.
b. the oldest "mistaken" C14 dates for "pre-flood" fossils (50,000years) is supposedly caused by a vastly different ratio of atmospheric C14-O2 : Cmundane-O2
c. the total carbon content of a "pre-flood" cow is identical to that of a "post-flood" cow
d. the only way the ratio could be changed would be by a drastic "pre-flood" elevation of the total CO2 content of the atmosphere.
With me so far? Ok...
e. Ignoring half-life calculations (as the C14 halflife is 5730 years, this is safe enough), the "pre-flood" CO2 level in the atmosphere MUST have been about 11 times what it was "immediately after the flood" (and continues to be today).
f. The current by-volume content of CO2 in air is roughly 3% (3 parts per hundred)
g. ELEVEN TIMES that amount is 33 parts per hundred-and-thiry, or 25.4% of a much heavier atmosphere than we have today.
h. Questions of the environmental impact of such a concentration of greenhouse gas aside, this level of CO2 is approaches the threshold of LETHALITY to all terrestrial animal life - 30% is the threshold.
i. bearing in mind that CO2 is heavier than oxygen and nitrogen, ground-level displacement of these gasses by CO2 would certainly have led to surface concentrations of CO2 well above the 30% mark.
j. According to this postulate put forth by the YEC crowd, it would seem that terrestrial animal life "before the flood" was utterly impossible.

These are just off-the-cuff problems that I, as a complete layman, can spot in the YEC C14 ratio proposal. I'm certain wiser heads can rip it far more thoroughly asunder.

You know you won't get a response to 118, right? They'll just brush it aside and move on to something else.

Someone posted a while ago that we have written records from Egyptian pharaohs who lived at about the same time as the supposed flood. Yet, none of them mention anything about such a deluge. No one has explained that, either.
