also you must think god is an idiot/stupid/etc................???
you believe he can create a man from NOTHING!!!
but you don't believe he can make a dinosaur fly...........????!!!!!!!!!!
you are contradicting yourself

What was the point of walking high into the mountains then? Gliding?

They seem to be built for flight and there is evidence of them flying long distances.

Uh ... If there is actual evidence of them "flying long distances" ...
Then it makes no difference too argue the idea of whether or not they can fly.

It might be a good idea to ask the professor how many flying reptiles he studied.
The quickest way to tell the difference in a bat and bird in the sky ... Is how it flies, they don't fly the same ...

.​

Which professor? Yes, the bat and the bird do not fly the same and we're discussing flying reptiles. Not gliding ones. The largest being in the quarter ton range. Neither bats nor birds are reptiles. More likely, the pterosaur flew like the large bird and could get enough thrust to fly from its launch position similar to a bat on all fours. Bats walk on fours. In fact, we don't know for certain how the pterosaur walked either.

 

[james bond]

harmonica at least you do not unlike that other idiot Fort Fun Indiana ha ha. You fail miserably. Your example can't fly and you can't explain how it grew so large.

 

[harmonica]

simple:

Dromaeosaurs such as Deinonychus, the model for the "raptors of Jurassic Park, were fierce predators that used their forearms in a motion that was very similar in unusual ways to the flight stroke of used in birds.

as Winterborn stated:

Avian Flight
Pterosaurian Flight

the 747 can't fly??

 

[james bond]

Let me throw harmonica a crumb since he likes to bring religion into science.

"Whatever crawls on its belly, and whatever walks on all fours, whatever has many feet, in respect to every swarming thing that swarms on the earth, you shall not eat them, for they are detestable." Leviticus 11:12

Bats are in this category. Otherwise, you can eat a bat to prove God wrong.

you fail--miserably
you said too heavy--too big
Pteranodon weight 55 lbs
747 910,000 lbs!!!!!!!!!!!!
fail

so god can make a man from nothing--but can't make dinos fly??
very ridiculous/idiotic/.nonsensical/etc

Maybe they were gliders.

Flight allowed pterosaurs to travel long distances, exploit new habitats, escape predators, and swoop down from above to seize their prey. They spread across the world and branched out into an enormous array of species, including the largest animals ever to take wing."

Yet, other scientists believe they were too big to fly due to physics. I think it's been agreed that they were the largest animals to fly.

Pterosaurs should have been too big to fly – so how did they manage it?

What was the point of walking high into mountains and then gliding? More likely they climbed cliffs to gain the vantage point from which to launch.

The point? Food. From directly above you can see fish and other creatures that live underwater. Glide, Dive, Eat, Repeat.

What you suggest goes against microevolution. Yes, my expert states that all pterosaurs used their superior gliding abilities to fly long distance. However, you assume the pterosaur walks on its hind legs. What if it walked on fours? Many scientists think it walked on fours.

Gravity was far less?

Now we are entering bizarro land

Why would a change to atmospheric density and gravity be bizarro? Earth's atmosphere is held in place by gravity.

Earth's atmosphere is made up of several gases. They each have their own density. The relative amounts of each gas has changed over the history of the Earth. So the density of the atmosphere has changed. That has been proven and recorded.

Gravity is a function of the mass of the planet and the Earth's rotation. This has not changed. Gravity was not significantly lighter only a few thousand years ago.

I disagree that gravity has not changed. The earth was smaller and thus the gravity less in ancient times, relatively speaking. We have the expanding earth theory.

The experts Witton and Habib state that even with the "same" gravity as today, the creatures still would be able to fly. Why have wings like bats and light bone structure if they could not fly? We have reports from people today that they fly. There's even a civil war picture that shows soldiers with one of them. I think they are living fossils and are capable of flight even in today's heavier gravity and larger earth.

The expanding earth theory was all the rage hundreds of years ago. But Plate Techtonics explain the jigsaw puzzle look of the continents.

Expanding earth theories are not taken seriously by most scientists. There is no mechanism of action. No measurements that can be shown. And the only real evidence is the fact that the continents would fit together if moved. But the break up of Pangea can be more easily explained by plate techtonics. And there is verifiable evidence that the Earth's crust is floating on semi-molten rock. And there is measurable movement in the Earth plates.

Okay, if the earth did not expand, then how do you explain the giganticism and how the largest pterosaur flew? What caused the atmosphere to be less dense?

The flight of the pterasaur I have already explained. The bone structure and the likelihood that much gliding was involved.

As for giants, you will have to be more specific. Legends? Myths? Just very vary people? What needs explaining?

The atmosphere s made up of several gasses. Each has a different density. For a number of reasons, the concentrations of any given gas can vary. Millions of years ago, there were very different levels of each gas. So the density would be different.

Structurally they are much like bats. Which climb very well, and even live on walls and ceilings. Climbing a cliff at the waters edge would be simple.

How would walking on all fours preclude climbing a cliff?

JB says god can create anything and every thing--except a dino bird that can fly!!!

You know, for a few years, I lived in Missoulla Montana, and hang gliding was pretty big there. People would jump off of the mountain, and would stay in the air, sometimes for hours because there were lots of thermals in the valley. Was really fun and interesting to see them catch one and glide around in an upward spiral.

Now, the OP originally posted that the dinosaur weighed around 50 lbs, and had a wingspan of around 18 ft.

Current hang gliders are approximately 24 ft across, and can carry people up to 250 lbs. Some places where they fly are so rampant with thermals that a person can jump off the mountain in the morning and not land until the evening.

With all that being said, yes, it is possible for the dinosaurs to have been able to glide quite effectively, and, there is also a chance that the shape of their head may have made it easy for them to detect thermals so they could fly up.

In some ways ... Flying is like controlled crashing ...
Like walking is controlled falling.
If you have ever seen a woodpecker fly ... They are a perfect example.​

caught you on this James...big mistake
either god can create anything or he didn't create anything

What caused the atmosphere to be less dense?

The atmosphere did not have to be less dense.
