Did Ancient Humans Coexisted with Dinosaurs?

a reply to: Raggedyman

So can you tell me, without any qualms, stegosaurases never evolved horns, ever, never ever, really

Evolved? What's that mean?

But yes, I can tell you that. Because with a large head and horns, it would not have been a stegosaur.

Oh please, do tell what dating method is used on "65 million year old" rocks? Is it the strata that it's in? or the fossils that are found within the rock...lol...

It sure as hell isn't potassium argon or any other radiological dating method. None are capable of going back far enough...Interesting how the dating isn't falsifiable...lol...

Electron Spin Resonance (ESR) Dating in Archaeology

Renaud Joannes-Boyau

Introduction
Electron spin resonance (ESR) has been used for absolute dating of archaeological materials such as quartz, flints, carbonate crystals, and fossil remains for nearly 50 years. The technique is based on the fact that certain crystal behaves as natural dosimeters. This means that electrons and holes are accumulated over time in the crystal lattice induced by surrounding radiation. The age is obtained by calculating the dose received compared to the dose rate generated by the surrounding environment, mainly radioisotopes K, U, and Th. The dating range is dependent on the nature and state of conservation of the sample and the surrounding environment but is between a few thousands and a couple of million years. Since, ESR dating is best and most commonly applied to tooth enamel in archaeology, this paper predominantly focuses on its direct application to fossil remains.

Fascinating method, truly. One question, though; how does one determine the environment of the item to be dated from a few million years back? Seems to be that could not be stated with any degree of certainty.

Evolved, like when a big dog is bred into a smaller dog...

So you know of every dinosaur to have ever existed
Wow, you must be smart

Thanks for clearing that up

For the record, dinosaurs are still alive today.

I know at least two members right here on ATS who would agree 100% with that statement...

Numerous other credible eyewitness sightings back it up as well...

Some years back, my brother and I saw something that could have been one of these. It was late at night (very common for us), and we were outside talking. Saw something really large (6-10 feet) flying around across the street. Both of us were, and are, quite familiar with various water birds, bats, birds of prey, etc, and this was none of those. Plus, there was something really menacing about it. It scared us both, and we didn't scare easily. That particular event has already been detailed to a researcher in the field, and should be in an upcoming book. Too many people report seeing these things to dismiss them out of hand.

*snip*

Oh, yeah! Still remember that night, and yeah, it did get printed up in a couple of books. No bird, I am sure of that. Very unfriendly thing, just like the tales of the ropen that you also mentioned. At the time, didn't even think about something "prehistoric", but seeing some of the witness videos, the feeling they showed in their eyes was so familiar, and the reports of these things being seen, and I started to wonder! Fits a pterosaur more than anything else I can name. Really don't ever want to see one again, either.

That isn't evolution. That is... wait for it... BREEDING.

And if you start a breeding program with a Saint Bernard and your breeding population gets smaller and smaller and its hair gets shorter and shorter and Paris Hilton starts carrying them around in her purse, you don't have a Saint Bernard anymore, you have a chihuahua.

If a population started out as stegosauri and evolved into animals with horns, the population would no longer be stegosauri. They would be something else, and that is what Phage was trying to tell you.

Its time for you to stop playing the troll now kiddies.

It might be a possibility.
Fodder for imaginations.

You must be the clever one

try wikipedia, try micro evolution, a whole new world will develop before your eyes, I promise

There is a reason the previous poster stepped back, he isnt foolish
He doesnt know if a dinosaur like the one depicted at Angkor Watt existed but hasnt been found, niether do I or you

Now as for stegasauri, old, real old stegasauri may have grown horns, maybe a branch of stegasauri, maybe a evolutionary change within a species of stegasauri

All we see are bones and bones prove basicaly that something living died, nothing else

Now, troll I maybe, but trolling for scientific evidence is my method

Unless the "scientific evidence" you're attempting to gather is directly related to a study on the forum responses engendered by trolling, your method is fundamentally flawed.

I should know. I once tried to collect scientific evidence on relativity by pooping in jar and calling it Susan.

I always found this image of man and dinosaurus footprints overlapping eachother very interesting.

Well I would be very grateful if you provided me with the evidence as opposed to a lecture about said evidence and its location or not
Dont people get tired of alking and just want to come up with the evidence

My method has to be flawed as I am asking for what doesnt exist and people are trying to offer me what doesnt exist as evidence
Its all stupid
Then occasionaly through the cloud of stupid, we get truth

The science of assumption, the truth

You can dance around a lie but eventually you will fall over it, look a fool.

(a) We have performed radioactive decay experiments for a long time, and no change has been observed.
(b) Radioactive dating agrees with different isotopes as well as other dating method. Carbon dating, for instance, can determine the ages of trees noted in historical documents.
(c)We have no evidence to suggest radioactive decay is not constant, as our understanding of physics suggests it should be, and anyone wishing to challenge this needs to present evidence for it.

a LOOOONG TIME is scientific.
No evidence to suggest, is assumption

You mean like when dogs grow horns?

Link below to an article about Titanis Walleri, a type of predatory bird native to South America that had clawed, prehensile hands and possibly thumbs, rather than wings. It's speculated that they become extinct 15000 years ago, which places them in the late pleistocene era along with early humans. I think these sorts of stone age creatures are the closest man have ever been to what people think of when they think of "typical" dinosaurs.

Man, i don't know how you do it. How do you manage to stay on this site without losing your mind? I mentally checked out long ago. Fortunately for this place, you are still one of the best and most logical members here.

Various types of stratigraphical analysis. Here's a few examples:

en.wikipedia.org...

The law of superposition is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy. In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. This is important to stratigraphic dating, which assumes that the law of superposition holds true and that an object cannot be older than the materials of which it is composed. The law was first proposed in the 17th century by the Danish scientist Nicolas Steno.

en.wikipedia.org...

The principle of faunal succession, also known as the law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna, and that these fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances. A fossilized Neanderthal bone will never be found in the same stratum as a fossilized Megalosaurus, for example, because neanderthals and megalosaurs lived during different geological periods, separated by many millions of years. This allows for strata to be identified and dated by the fossils found within.

www.crowcanyon.org...

Remember, they're not dating down to the exact year - it's over millions of years. Peter V would be more knowledgeable about this. I presume that they also compare various types of spectroscopic data with the strata samples. The oil industry was actually very instrumental in developing dating techniques and identifying various types of geological formations.

a reply to: Raggedyman

I haven't assumed anything. What I'm telling you is based on scientific experiments. If there is some magical way the decay rate can change, it's on you to show because thus far scientists have been unable to make it change. It's a constant, just like gravity and the other universal forces. If you think those things can change you need to show how and why instead of just assuming all the science is wrong.

You are thinking of triceratops. If stegosaurus had horns, it would be a different species. That's like asking how you know humans have never evolved horns. It's laughably stupid.

Hahhaaaaa! I just laughed so hard I almost choked! Thanks for brightening my day!

Life in general happens when conditions are right. Earth has knocked life back to simple forms a number of times just to see it spring back up very quickly. After snowball earth within a couple of 100 million years we went from almost nothing to extremely vast amounts of life like dinosaurs...

As common as life can be species is a different story. They come and go all the time... a couple of million years or less and they live out their existence making way to other species to do the same. Man is no different...Go back a few 100k years and and there really wasn't any Homo sapiens around, now go forward a million or so years and Homo sapiens will be something else or extinct completely like the vast majority of all species do.

I don't think you can fit dinosaurs in any of this....

Raggedy, why don't you stop annoying people to death. You have no interest in science much less how it's done.
So please give everyone a break and just stop it.
