How do you find a dinosaur? Sounds impossible, doesn’t it? It’s not. And the answer relies on a formula
that all paleontologists use. And I’m going to tell you the secret. First, find rocks of the right age. Second, those rocks
must be sedimentary rocks. And third, layers of those rocks
must be naturally exposed. That’s it. Find those three things
and get yourself on the ground, chances are good
that you will find fossils. Now let me break down this formula. Organisms exist only during certain
geological intervals. So you have to find
rocks of the right age, depending on what your interests are. If you want to find trilobites, you have to find the really,
really old rocks of the Paleozoic — rocks between a half a billion
and a quarter-billion years old. Now, if you want to find dinosaurs, don’t look in the Paleozoic,
you won’t find them. They hadn’t evolved yet. You have to find the younger
rocks of the Mesozoic, and in the case of dinosaurs, between 235 and 66 million years ago. Now, it’s fairly easy to find rocks
of the right age at this point, because the Earth is, to a coarse degree, geologically mapped. This is hard-won information. The annals of Earth history
are written in rocks, one chapter upon the next, such that the oldest pages are on bottom and the youngest on top. Now, were it quite that easy,
geologists would rejoice. It’s not. The library of Earth is an old one. It has no librarian to impose order. Operating over vast swaths of time, myriad geological processes
offer every possible insult to the rocks of ages. Most pages are destroyed
soon after being written. Some pages are overwritten, creating difficult-to-decipher palimpsests
of long-gone landscapes. Pages that do find sanctuary
under the advancing sands of time are never truly safe. Unlike the Moon —
our dead, rocky companion — the Earth is alive, pulsing
with creative and destructive forces that power its geological metabolism. Lunar rocks brought back
by the Apollo astronauts all date back to about the age
of the Solar System. Moon rocks are forever. Earth rocks, on the other hand,
face the perils of a living lithosphere. All will suffer ruination, through some combination
of mutilation, compression, folding, tearing, scorching and baking. Thus, the volumes of Earth history
are incomplete and disheveled. The library is vast and magnificent — but decrepit. And it was this tattered complexity
in the rock record that obscured its meaning
until relatively recently. Nature provided no card catalog
for geologists — this would have to be invented. Five thousand years after the Sumerians
learned to record their thoughts on clay tablets, the Earth’s volumes remained
inscrutable to humans. We were geologically illiterate, unaware of the antiquity
of our own planet and ignorant of our connection to deep time. It wasn’t until the turn
of the 19th century that our blinders were removed, first, with the publication
of James Hutton’s “Theory of the Earth,” in which he told us that the Earth
reveals no vestige of a beginning and no prospect of an end; and then, with the printing
of William Smith’s map of Britain, the first country-scale geological map, giving us for the first time predictive insight into where
certain types of rocks might occur. After that, you could say things like, “If we go over there,
we should be in the Jurassic,” or, “If we go up over that hill,
we should find the Cretaceous.” So now, if you want to find trilobites, get yourself a good geological map and go to the rocks of the Paleozoic. If you want to find dinosaurs like I do, find the rocks of Mesozoic and go there. Now of course, you can only make
a fossil in a sedimentary rock, a rock made by sand and mud. You can’t have a fossil in an igneous rock formed
by magma, like a granite, or in a metamorphic rock
that’s been heated and squeezed. And you have to get yourself in a desert. It’s not that dinosaurs
particularly lived in deserts; they lived on every land mass and in every imaginable environment. It’s that you need to go to a place
that’s a desert today, a place that doesn’t have
too many plants covering up the rocks, and a place where erosion is always
exposing new bones at the surface. So find those three things: rocks of the right age, that are sedimentary rocks, in a desert, and get yourself on the ground, and you literally walk until you see a bone
sticking out of the rock. Here’s a picture that I took
in Southern Patagonia. Every pebble that you see
on the ground there is a piece of dinosaur bone. So when you’re in that right situation, it’s not a question of whether
you’ll find fossils or not; you’re going to find fossils. The question is: Will you find something
that is scientifically significant? And to help with that, I’m going to add
a fourth part to our formula, which is this: get as far away from other
paleontologists as possible. (Laughter) It’s not that I don’t like
other paleontologists. When you go to a place
that’s relatively unexplored, you have a much better chance
of not only finding fossils but of finding something
that’s new to science. So that’s my formula
for finding dinosaurs, and I’ve applied it all around the world. In the austral summer of 2004, I went to the bottom of South America, to the bottom of Patagonia, Argentina, to prospect for dinosaurs: a place that had terrestrial
sedimentary rocks of the right age, in a desert, a place that had been barely visited
by paleontologists. And we found this. This is a femur, a thigh bone, of a giant, plant-eating dinosaur. That bone is 2.2 meters across. That’s over seven feet long. Now, unfortunately,
that bone was isolated. We dug and dug and dug,
and there wasn’t another bone around. But it made us hungry to go back
the next year for more. And on the first day
of that next field season, I found this: another two-meter femur, only this time not isolated, this time associated with 145 other bones of a giant plant eater. And after three more hard,
really brutal field seasons, the quarry came to look like this. And there you see the tail
of that great beast wrapping around me. The giant that lay in this grave,
the new species of dinosaur, we would eventually call
“Dreadnoughtus schrani.” Dreadnoughtus was 85 feet
from snout to tail. It stood two-and-a-half stories
at the shoulder, and all fleshed out in life,
it weighed 65 tons. People ask me sometimes,
“Was Dreadnoughtus bigger than a T. rex?” That’s the mass of eight or nine T. rex. Now, one of the really cool things
about being a paleontologist is when you find a new species,
you get to name it. And I’ve always thought it a shame
that these giant, plant-eating dinosaurs are too often portrayed as passive,
lumbering platters of meat on the landscape. (Laughter) They’re not. Big herbivores can be surly,
and they can be territorial — you do not want to mess with a hippo
or a rhino or a water buffalo. The bison in Yellowstone injure
far more people than do the grizzly bears. So can you imagine a big bull,
65-ton Dreadnoughtus in the breeding season, defending a territory? That animal would have been
incredibly dangerous, a menace to all around, and itself
would have had nothing to fear. And thus the name, “Dreadnoughtus,” or, “fears nothing.” Now, to grow so large, an animal like Dreadnoughtus
would’ve had to have been a model of efficiency. That long neck and long tail help it
radiate heat into the environment, passively controlling its temperature. And that long neck also serves
as a super-efficient feeding mechanism. Dreadnoughtus could stand
in one place and with that neck clear out a huge envelope of vegetation, taking in tens of thousands of calories
while expending very few. And these animals evolved
a bulldog-like wide-gait stance, giving them immense stability, because when you’re 65 tons,
when you’re literally as big as a house, the penalty for falling over is death. Yeah, these animals are big and tough, but they won’t take a blow like that. Dreadnoughtus falls over,
ribs break and pierce lungs. Organs burst. If you’re a big 65-ton Dreadnoughtus, you don’t get to fall down
in life — even once. Now, after this particular
Dreadnoughtus carcass was buried and de-fleshed by a multitude
of bacteria, worms and insects, its bones underwent a brief metamorphosis, exchanging molecules with the groundwater and becoming more and more
like the entombing rock. As layer upon layer
of sediment accumulated, pressure from all sides
weighed in like a stony glove whose firm and enduring grip held
each bone in a stabilizing embrace. And then came the long … nothing. Epoch after epoch of sameness, nonevents without number. All the while, the skeleton lay
everlasting and unchanging in perfect equilibrium within its rocky grave. Meanwhile, Earth history unfolded above. The dinosaurs would reign
for another 12 million years before their hegemony was snuffed out
in a fiery apocalypse. The continents drifted. The mammals rose. The Ice Age came. And then, in East Africa, an unpromising species of ape
evolved the odd trick of sentient thought. These brainy primates were not
particularly fast or strong. But they excelled at covering ground, and in a remarkable diaspora surpassing even the dinosaurs’ record
of territorial conquest, they dispersed across the planet, ravishing every ecosystem
they encountered, along the way, inventing culture
and metalworking and painting and dance and music and science and rocket ships that would eventually
take 12 particularly excellent apes to the surface of the Moon. With seven billion peripatetic
Homo sapiens on the planet, it was perhaps inevitable that one of them would eventually
trod on the grave of the magnificent titan buried beneath the badlands
of Southern Patagonia. I was that ape. And standing there, alone in the desert, it was not lost on me that the chance of any one individual
entering the fossil record is vanishingly small. But the Earth is very, very old. And over vast tracts of time,
the improbable becomes the probable. That’s the magic of the geological record. Thus, multitudinous creatures
living and dying on an old planet leave behind immense numbers of fossils, each one a small miracle, but collectively, inevitable. Sixty-six million years ago,
an asteroid hits the Earth and wipes out the dinosaurs. This easily might not have been. But we only get one history,
and it’s the one that we have. But this particular reality
was not inevitable. The tiniest perturbation
of that asteroid far from Earth would have caused it to miss
our planet by a wide margin. The pivotal, calamitous day during which
the dinosaurs were wiped out, setting the stage
for the modern world as we know it didn’t have to be. It could’ve just been another day — a Thursday, perhaps — among the 63 billion days
already enjoyed by the dinosaurs. But over geological time, improbable, nearly impossible events do occur. Along the path from our wormy,
Cambrian ancestors to primates dressed in suits, innumerable forks in the road
led us to this very particular reality. The bones of Dreadnoughtus
lay underground for 77 million years. Who could have imagined that a single species of shrew-like mammal living in the cracks of the dinosaur world would evolve into sentient beings capable of characterizing
and understanding the very dinosaurs they must have dreaded? I once stood at the head
of the Missouri River and bestraddled it. There, it’s nothing more
than a gurgle of water that issues forth from beneath a rock
in a boulder in a pasture, high in the Bitterroot Mountains. The stream next to it
runs a few hundred yards and ends in a small pond. Those two streams — they look identical. But one is an anonymous trickle of water, and the other is the Missouri River. Now go down to the mouth
of the Missouri, near St. Louis, and it’s pretty obvious
that that river is a big deal. But go up into the Bitterroots
and look at the Missouri, and human prospection does not
allow us to see it as anything special. Now go back to the Cretaceous Period and look at our tiny, fuzzball ancestors. You would never guess that they would amount
to anything special, and they probably wouldn’t have, were it not for that pesky asteroid. Now, make a thousand more worlds
and a thousand more solar systems and let them run. You will never get the same result. No doubt, those worlds would be
both amazing and amazingly improbable, but they would not be our world
and they would not have our history. There are an infinite number of histories
that we could’ve had. We only get one, and wow,
did we ever get a good one. Dinosaurs like Dreadnoughtus were real. Sea monsters like the mosasaur were real. Dragonflies with the wingspan of an eagle
and pill bugs the length of a car really existed. Why study the ancient past? Because it gives us perspective and humility. The dinosaurs died in the world’s
fifth mass extinction, snuffed out in a cosmic accident
through no fault of their own. They didn’t see it coming,
and they didn’t have a choice. We, on the other hand, do have a choice. And the nature of the fossil record
tells us that our place on this planet is both precarious
and potentially fleeting. Right now, our species is propagating
an environmental disaster of geological proportions
that is so broad and so severe, it can rightly be called
the sixth extinction. Only unlike the dinosaurs, we can see it coming. And unlike the dinosaurs, we can do something about it. That choice is ours. Thank you. (Applause)

    Noone asks why at certain dig sites, you find fossils that are apparently 300 billion years old sitting along with ones that are 60 million years old. Maybe times are a bit off, but its strange that it seems more like a mass flood deposited them together and it actually makes more sense.

    Its truly depresing that we didnt made some small outpost on Mars just for very case of some catastrophe. That would save our kind and maybe very life of Earth. But our leaders are too primitive to realize such biger things.
    If we ever have some descendants they will see as as some stupid half animals which didnt had real understanding of even basics like self preservation of species.

    Not a single ancient inscription mentions Dinosaurs
    Not a single religious book mentions Dinosaurs

    "Unlike the dinosaurs we can see it coming, unlike the dinosaurs we can do something about it." When in reality, the only thing we do a majority of, in terms of doing something about it, is making it consistently and gradually worse. It may be slow in coming, but we are damaging earth to a degree that I deem irreparable. What's worse, to use his words, too few apes are like him, and too many are destructive and virus like in our assimilation of environments. See it coming? Apparently, being sadists isn't enough, we are also masochists fanning the flame of our mutually assured destruction. The implications are extremely grim. The probability of surviving was low for dinosaurs, who lived in harmony and balance to a degree with their environment. Even so, they were wiped out. Therefore, the probability seems high that our fate will be the same as theirs. Be it by an unknown soon to be discovered too late force, or by our own hand.

    A herbivore injures far more people in Yellowstone than the carnivore? A territorial dinosaur that is a herbivore. Sounds kind of like those in our species dubbed vegans and vegetarians. They form groups who get violent against the meat eaters and worry about what others are doing vs what they are doing. Interesting insight into the untold violent/primal behavior into plant only eaters. Thanks! Veginoughtus or Veganoughtus! Creatures to be feared. Run my fellow meat eaters, run!

    I know many will disagree with me. But I think the evidence points to an entirely different scenario. Notice how all the "oldest" creatures buried at the lowest level. Are all creatures that were already in the dirt or lived right on the surface. Move up, you have you slow moving creatures, moving up, you have faster creatures, above that much faster creatures. And above that is your flying animals. But this isn't 100 percent cut and dry. There are creatures that are in the very lowest layer. Shells, clams. Up on the tops of out highest mountains. Even Mount Everest. But These would be the creatures. That when this catastrophe occurred they were already in the ground. What I see here is evidence for a worldwide flood where all of its inhabitants were separated through the process of liquefaction.

    Science is the systematic study of the structure and behavior of the physical and natural world through OBSERVATION and EXPERIMENT. Religion is believing in something without proof, having only faith that certain events actually took place. Evolution is RELIGION but it's sold to the public as "science". There is no proof that humans evolved from primates. Our only "missing link" Lucy, a primate was "discovered" by a man whose research funding was 2 weeks away from getting pulled if he wasn't able to find the "missing link" which is specifically what he was being funded to do. I don't have all the answers, but I can smell BS when it's under my nose.

    10:05 dinosaurs were on earth for about 12 million years? I thought the entire mesozoic era was the age of the dinosaurs.

    Does it start to annoy anyone else that they all say thank you at the end? Didn’t used to bug me but now it bugs me a bit.

    That "fossil layer" from the chart exists nowhere on earth. Nowhere do you find layers with fossils as shown on the chart, nor do you find transitional forms. Nice hobby and all.

    Another who hasn't got a clue how old the earth is,You would need a sample of earth from day 1, the climatic conditions from day 1 and recorded climatic condition data from then until now to give a accurate assessment.
    Funny how he doesn't mention the writings of Marco Polo,Job,Pliney The Elder amongst others who documented actually seeing living dinosaurs.
    Yes he his just another bluffer who thinks by speaking somewhat eloquently he can fool everyone, LMAO.
    BTW We don't have a choice what choice do we have if another meteor hits planet earth you absolute bellend ? Yeah none at all,Case closed.

    These idiots are full of it. It doesn’t take millions of years for the dinosaurs to decompose to that level. Science has shown that decomposition can take as little as a few years. They have no idea how old the earth or the solar system is. All they can do is guess. And they are terrible at that as well.
    Carbon dating is a failure.

    Wow, so disappointing to see how many people are blind religious fanatics or pseudo-science supporters. They don't want to spend their time on understanding numerous evidences evolution theory is based on and just shout: "I am not an ape!", "Darwin lied!", etc.

    So, this is a new species? I've watched another guy, I think it's just a bigger dino than found before, congrats. Lucy is still a fake. Speaking well, does not make any of it true.

    I just watched a video of jack horner ted video how scientists like to name new dinosaurs. How different dinosaurs are the same dinosaurs, just different age. I believe this dinosaur is basically a brontosaurus/brachiosaurus/apatosaurus.

    "… a 6th extinction event …" This is where are now: a potential extinction event. Consider: in the previous 5 events the Earth remained, the dominant life forms went away. As I've repeatedly said to the self-righteous, 'Save the planet,' people, "THERE IS NOTHING WRONG WITH THE PLANET. The Earth has been through MUCH worse than us. You think some toxic gasses, plastic bottles and styrofoam cups are somehow posing a 'threat' to the planet?
    THE EARTH IS NOT GOING ANYWHERE … WE ARE!
    And when we are gone, the Earth – over time – will completely heal itself and, without interruption, continue it's little repetitive journey around the sun."

    He presents assumptions as facts, which is common for scientists as well as religious zealots.

    We do have a love affair with the Dinosaur. Though they are fascinating, it leaves me laughing when illustrators paint them around tint trees hahaha.
    If animals were big, the trees and plants they fed on were even bigger. Those long necks were designed to feed on low hanging branches of giant trees that soared 100's, if not 1000's of feet into the heavens. Their remains are all around us in the for of petrified tree stumps. We call them mountains and plateaus.
    Check this guy out https://www.youtube.com/watch?v=2ENP5qwlL7I&t=23526s. The evidence he presents is undeniable, and absolutely fascinating.

    Every time is see a scientist or any kind of career intellectual tell a crowd that we're seeing it coming and we have the choice to do something about it, I always come to think that we've chosen to do nothing. We don't really care about the planet, and we don't really care about our children or our children's children. We're not worthy of surviving extinction.

    Humanity has the awareness, sure. But we're still short-sighted, careless and stupid. Better luck to the next batch.
    Maybe dolphins will survive and evolve into a better species than we ever were.

    He wasn’t hinting at global climate change at the end, because mankind can easily adapt to any temperature. Kenny was hinting at something far more fearful and imminent.
