I'm guessing it flew. It is like a mathematical equation where you have more than one variable. In this case lots of variables, since we do not have a complete creature to test fly and we do not know what the environment was like when it lived.

But the range of possibilities are in two categories:
1. things we don't yet know (or haven't thought about) regarding the animal.
2. Things we don't yet know (or haven't thought about) regarding the environment in which it lived.

The solution to this puzzle could be in one or both categories.

Regarding the Bronto...I mean, Apatosaurus, there is a lot of speculation going on regarding all sorts of things - not just tendons, but blood pressure variances, etc. There's more to it than the pictures in schoolbooks, and people need to be educated about such things.

Actually, a scientist built a 1/2 scale model of Quetzalcoatlus about 15 or so years ago and flew it in the desert of West Texas. (yes, they had to 'launch it' off the ground, but, once it was up in the air, it dropped the launching gear and flapped its wings, soaring effortlessly on the wind currents.)

From Wikipedia:"MacCready also developed, for the Smithsonian Institution, a half-scale replica of the giant pterosaur, Quetzalcoatlus northropi. The model had a wingspan of 5.5 meters (18 feet) and featured a complex, computerized control system, just as the full-size pterosaur relied on its neuromuscular system to make constant adjustments in flight."

Here is the link to a short video of its flight:

I believe it, but it only proves aerodynamics.

First, it was half scale, and size matters. Second, it was not made of living material.

As I understand it, even with hollow bones, etc., modern birds cannot fly once a maximum weight of around 35 lbs is reached. At that point, it takes more than a pound of muscle/bone/feather/membrane to produce a pound of lift. So the farther from 35 lbs you get, the more impractical it becomes.

I wonder if there was any mylar and carbon fiber in the half scale model? ;)

"Maybe you need to check out the definition of "bash":
To criticize harshly; To engage in harsh, accusatory criticism. "

Ahhh, BASH. I didn't get that. Does that include a self-righteous poster who starts a flame by telling someone that they must have been hitting the bottle mighty early this morning? You must have mistaken me for one of your flock. I don't drink.

"I think we're done here."

I'll let you know when I'm done. It would seem that the bashing has been attempted by you, (not that you are very good at it) and now you would really like someone to feel sorry for you. I'll do that. I feel sorry that self-righteous people like you can't find happiness in life unless they are sure all the others around them are going to hell.

Still no facts about T-Rex?

Ok, we're done. Have a nice day, Dem.

and you darn well know that the technical physics of how bees actually stay aloft was a mystery until fairly recently....

And how is that relevent to the assertion that "scientists" said bee flight is "impossible"?

It sounds a bit like saying evolution or abiogenesis is impossible because parts are still a mystery.

A-bio-whatsis? :>0

I was making the argument that just because we can't figure out how nature works in all instances doesn't mean that it doesn't....(it was a reply to the 'Pterosaur's were too big too fly' argument that I seem to recall someone - not sure who anymore - made...)

The T Rex birth rate is too low to support Evolutionary arguments of random mutations occuring fast enough to bring about species change.

Please post the actual calculations or a link.

LOL. Taking up where I left off? I think SH gets his concept of mutations from Hollywood. If you can't see it at 20 paces, it doesn't exist.

Possibly not a bad policy for examining crocks and gators.

OK, but you'll just deny the math or the link or the context. Evolutionists are *never* persuaded by math.

... The wages of sin is death is from the bible. Some believe this means no death of any kind occurred before the fall of man. ...

This has got to be one of the silliest things I've ever heard of. How anyone can take (or pretend to take) such ideas and the people who spread them seriously is beyond me.

For example, there are Burgess Shale trilobites with big nasty bites chomped off. There are no bones, much less people, in the Cambrian. No fish, no reptiles, no birds, no bones at all. None.

...My only point is that animals do not have spirits...

A minority opinion. AFAIK, only Jews, Christians, Muslims, and atheists deny animals having spirits. Hindus, Buddhists, and animists all assert that they do.

Is it possible for a chihuahua and a great Dane to mate?

If you want some math that employs raw chance and has at least some relevance, take a look at the cash flow at a casino. Every wager is stochastic, and yet the trend is inexorable.

It is bad form to talk about other Freepers behind their backs.

And you are confusing Southack's guess with a fact.

"If you want some math that employs raw chance and has at least some relevance, take a look at the cash flow at a casino. Every wager is stochastic, and yet the trend is inexorable."

Ironically, your example of casino math only conveys a single trend (i.e. the house eventually wins), failing to yield enough properly sequenced data to code a life form (e.g. red casino chips being DNA A, green casino chips being DNA G, black casino chips being DNA T, blue casino chips being DNA C) or otherwise convey any meaningful amount of information.

In fact, the sum of all casinos playing colored chips over all of history will not, statistically, properly sequence (by chance) the DNA of even the most simple life form.

Not even once.

It is a minority opinion that Jesus is God in the flesh. There is even a movie about the "minority opinion".

Sometimes the minority is right.
