- Explore the incredible world of ancient fossils and uncover the secrets behind how they are dated. Learn how archaeologists use relative and absolute dating methods to determine the age of fossils ranging from just a few years old to billions of years old.
I don’t get the 2nd method. You stated that we have an exact number for how long certain elements take to decay (like Carbon in your example), but isn’t it known that decay depends on the environments (like whether it’s dry or humid)? This can determine whether bones decay over a few years vs over thousands of years according to google. Please explain.
Good video. Need to check out that Argon dating process.
Great job sir thanks
Explained in a simple and beautiful manner ❤

Good vedio
Explain about human evolution... In detail
Perfect explanitaion ❤
well explained ❤
Amazing explaination .Love from Pakisan
Thank you thank you so much sir
Crystal clear ❤❤❤
exellent explained.
I have a huge problem with relative dating and argon potassium dating. Just because the rock/dirtv s next to the fossil, does not make them the same age. It only means they were deposited in that spot at the same time. The rock was likely formed much earlier
Well no, fossils can only be found in sedimentary rock. Sedimentary rocks are formed by a bunch of layers of sand or other material being stacked on top of each other. The pressure of all these layers compresses the lowers layers and creates stone. So when a dinosaur dies and decomposes and there is left are bones and layers and layers of sand are being laid on top of these bones eventually when the stone is formed the bones will be ingrained in the stone. And there for the fossil and the rocks in or around it will be around the same age.
Awesome explanation , thank you so much 🙏🙏
Amazing
Nice
awesome
What are index fossils
Awesome explanation
I love this video.
Me too
I thought the same thing!
Tell me process of detecting age of fossils is there any chemicals use in them
Aren't bones just rock now tho? Because of the permineralization
they used to think so. A lot of Dinosaur bones have soft tissue in the core of them now.
@@benjones5799they are wrong, and will not admit they are wrong. They claim agates are formed in a volcanic tube or void, this is not entirely true. Agates are from biological origins. Every agate is biology turned to stone just like petrified wood. And most rocks are also from a biological origin other than volcanic rocks. The rest were once living organisms turned to stone. Even meteors are from biological origins.
textbooks still say it turns to stone :( Earth science textbook here in New York @@benjones5799

Um... neutrons are in the nucleus of an atom, and electrons are outside the nucleus. The visualization of carbon's isotopes makes it look like the neutrons are outside...
🤟
carbon dating method ?
Carbon dating only works upto 60000 years
Human being brain !
Atomic decay doesnt take 5730 years, thats how long until carbon decays by half.
So we can say its only guessing 🤪
It's not a guess, it's called estimation. With some level of confidence. Obviously fossils don't come with a birth certificate.
@@buttofthejoke👍
@@buttofthejokefor real.
@@buttofthejokebro why you so mad telling this to everyone I'm guessing you're atheist??
comment 101 lesssss goooooooo
Did the narrator just say that archaeologists say this dinosaur bone could be a million years old?
Yah
Archaeologists don't do fossils, palaeontologists do!
I'm so glad someone caught that too!
There are assumptions in the approach of radioactive dating that need to be admitted and addressed, but we’re not mentioned here. We assume we know the rock’s initial conditions and what percentage has decayed. We assume no outside circumstances that could contaminate any test occurred between the formation of the rocks and our dating. And we assume the rate of decay has remained constant throughout time. We do not know any of these things definitively and we were not there in the beginning or throughout time.
How are these assumptions addressed?
With a simple google search
So basically guessing!?!
u have a better idea?
Educated guessing

Yup! 😂
Brain dead
Did you see they skipped the part explaining how they came to the conclusion atomic decay is 5730 years? Hmmm... 🤔
That was the half life of carbon 14 which he explained if you listened. That's the time it took for half of all the atoms of C14 to decay into N14
More like 5,300 years
Just making a bunch of stuff up. Good job science !
but how do they know the life of potassium argon dating if we've only been scientifically proficient for 200 years ??
He just explained it? And what does "us" being "scientifically proficient" have to do with anything?
@@ProfessorGunkhe is asking how do they know carbon 14 turns to nitrogen 14 in 5000 years and potassium argon 4.5 billion years or whatever what is the scientific proof of that
The half-life (t₁/₂) of a radioactive isotope can be calculated using the formula:
\[ N_t = N_0 \left( \frac{1}{2}
ight)^\frac{t}{t_{1/2}} \]
Where:
- \( N_t \) is the quantity of the substance that still remains after time \( t \),
- \( N_0 \) is the initial quantity of the substance,
- \( t \) is the elapsed time, and
- \( t_{1/2} \) is the half-life.
Let's rearrange the formula to solve for \( t_{1/2} \):
\[ \left( \frac{1}{2}
ight)^\frac{t}{t_{1/2}} = \frac{N_t}{N_0} \]
Taking the natural logarithm (ln) of both sides:
\[ \frac{t}{t_{1/2}} \cdot \ln\left(\frac{1}{2}
ight) = \ln\left(\frac{N_t}{N_0}
ight) \]
Now, solve for \( t_{1/2} \):
\[ t_{1/2} = \frac{t}{\ln\left(\frac{1}{2}
ight)} \cdot \ln\left(\frac{N_t}{N_0}
ight) \]
For potassium-40, with a half-life of about 1.3 billion years, you can plug in the values to calculate the specific time.

@@luisgordillo1695 Dr. Leonard McCoy doesn't know a thing about evolution 😂😅😂
I tried my best to figure out if there is any truth for scientists to accurately predict how old fossils are, and I still find it hard to believe if any fossil is millions of years old. To be honest, the scientific process in explaining things that are millions of years old sounds very fishy to me. In 200 years, most things vanish or go out of existence...
These are fossils. Google them!
Just a guy with no clue aren't you
Those fossil is no more than 7000-8000 years ago. As if there's no 'force' in nature that can change that timeline calculation.
So they have know idea . For the most part it's BS.
Oh My God I didn't know this , this is such bullshit, so you are telling me if we found a dinosaur bone randomly there is actually no way of knowing how old it is the makes me lose faith in this whole thing.
What do you mean find dinosaur bone randomly dinosaur bones are found enveloped in rock when the earth’s internal forces pushes it upwards
@@lilspacecoupe1585 Yeah but that could be anywhere in the world right? so if we can't carbon date the fossils themselves, it is really not accurate.
@@antoniobrown6210 you can date the rock the bone was found in
@@lilspacecoupe1585 And then assume that is how old the fossil is as if the earth is dormant ?
@@antoniobrown6210 you make no sense
Later physicist in heaven try to carbon dating heaven
You'll have about as much luck as you would trying to carbon date Narnia, both are just as true.
Humans going to heaven after they die is just an old pagan idea copied by kids who called themselves "monotheist". Grow up dude!
Fossils are clearly NOT millions of years old. We found soft pliable tissue in T-rex bones in the year 1995, and tissue in hydrosaur bones in the year 2009!
Turn to our lord and saviour Jesus so you can enter his kingdom of God and change your and others lives and souls in Jesus precious and almighty name amen❤❤❤❤
Lol stupid
amen brother! Jesus is king✝️
stfu go touch grass
But the rock would have been formed way before the fossil was buried
Evolution is b.s.!
Ou shut up you uneducated fairytale sucker
Science works
5:55 (I'm just curious not judging guys) How you can estimate a bone's age by estimating the age of rock besides it, that rock doesn't belong to the bone sir, and even you suggesting that the particles of rock or bone got under the influence of rock molecules or particals, the outcome or estimation still come for a rock not a bone.🦴
Yes we are assuming the rock layer was undisturbed when it was formed so therefore the fossil is approximately the same age as the rock surrounding it that was dated numerically. It would be the same as your laundry that is next to other clothes in the laundry basket all having been placed there approximately the same time, oldest on bottom and youngest on top.
@@lisashoaf7163 @lisashoaf7163 Thanks for answering the question but dear mam, what if somehow someone disturbed the laundry clothes and somehow bottom clothes and upper layer of clothes get upside down, no-one witnessed it, that's same applies on the fossils like if there is some kind of natural disaster like earthquake happen there or anything and rocks along with fossils got upside down somehow, and that's how we're no more able to assuming that the rock state is never disturbed, now my same old statement coperate the question here. And we're again on same question mam.
