What Really Killed the Dinosaurs?

What Really Killed the Dinosaurs?


So you just clicked on this video, you saw
the title – you probably think you already know the answer to this question. But as it often turns out, the science is
more complicated than what we have been told. First, let’s take a look at the story we’ve
heard, and why we’re so sure that an asteroid impact was a big part of the dinosaurs not
existing anymore. [Intro] I’m not gonna lie to you. It was a really
bad day. Some time around 66 million years ago, a giant asteroid about the size of Manhattan
careened into Earth. It smashed into the ocean on the shores of what we now think of as the
Gulf of Mexico and caused lasting damage to the planet. The energy of the impact itself vaporized
every living thing within a day’s walk. Then huge chunks of the meteorite that had been
thrown up into the atmosphere started raining back down as molten glass. The ensuing cloud
of ash and dust that was vaulted into the atmosphere obscured the sun for decades, creating
a dim, cold climate plagued by acid rain and firestorms. Over the millennia that followed,
at least 50% of the species on Earth disappeared – 20% of the world’s species of sharks, rays,
and skates; nearly 60% of the plants; 98% of the warm-water corals; and of course, 100%
of the dinosaurs. For most of us, that collision has become
a kind of shorthand explanation for why the dinosaurs disappeared, and because we associate
asteroids with extinction, it’s a scenario that still scares us. But as our knowledge expands, we’ve come to
see that what killed the dinosaurs, like all of the other great extinctions that happened
before, was probably a lot more complex than just a big rock falling into the ocean. Because
it turns out, there was more than one disaster movie playing at the cineplex that was Earth
66 million years ago. It was such a calamity that it literally,
in geological terms, marked the end of an era. The dinosaur dominated period of life
that we knew as the Cretaceous Era was suddenly over. The new normal, marked by the rise of
mammals, would be called the Paleogene Era. The giant die-out that created this transition
is now known as the Cretaceous-Palogene Extinction Event, or the K-Pg for short. And like many
things in science, there’s not a whole lot of consensus about what caused the K-Pg, but
there are a few facts that everyone agrees on. First, about 66 million years ago, the climate
changed, a lot, all over the world. We can tell by changes in the types of marine fossils
from both before and after the event, along with differences in soil chemistry and other
evidence that the climate became much cooler really fast – by 7 degrees Celsius in some
places. The transition was so abrupt that the layer
of rock that separates the before picture from the after picture is easy to spot with
a well-trained eye. It’s known as the Cretaceous-Palogene Boundary, and the chemistry of this boundary
of rock is itself another weird clue, because it shows up all over the world in the same
way – a sudden appearance of a layer of clay that’s rich in iridium. Iridium is a metal,
and if you’ve never heard of it, that’s because it’s very rare on earth. We tend to find it
most often in meteorites and other celestial deposits. The last clue that everyone agrees on is simply
extinction itself – tons of living things just disappear from the fossil record. Tyrannosaurus
Rex, the biggest land predator at the time, Bennettitales, a group of tall plants with
thick armored trunks, and whole passel of reptiles that lived alongside the dinosaurs
and are still sometimes mistaken for them. Aquatic reptiles like mosasaurs and plesiosaurs,
and pterosaurs – those freaky flying reptiles – all of them, gone. So the reason that the Asteroid Impact Theory
is so compelling is that it explains pretty much all of those things. The theory first
came about because of that iridium. In 1980 geologist Walter Alvarez was studying clay
deposits in Italy that dated back about 65 million years and found that they contained
hundreds of times more iridium than normal, and the more of that stratum of the earth
that he sampled in different parts of the world, the more iridium he found. Since iridium is rare on earth but plentiful
in space-rocks, Alvarez and his father – Nobel prize winning physicist Luis Alvarez – hypothesized
that it was a sign of an enormous asteroid impact. Based on the amount of iridium they’d
found, they figured that the collision was caused by a giant metallic rock, about 10
kilometers across – big enough create an impact with the energy of 180,000,000 megatons of
TNT. Clearly, it was a game changer. Alvarez and son theorized that this collision must
have been what wiped out the dinosaurs. Soon, scientists stared finding other signs
of a colossal asteroid impact – like shocked quartz. At K-Pg sites around the world, the
quartz looked like it had been transformed – its crystals rearranged by tremendous pressure
that you’d never suspect to find on earth’s surface. Then they found tektites – big tear-dropped
shaped pieces of glass that form when rocks are thrown into the atmosphere by an impact
and then melt on re-entry. So all the signs pointed towards a huge, ugly collision. But there was one thing missing – a crater!
Scientists new about a lot of different impact craters around the world, but none of them
matched the magnitude of the one that the Alvarezes envisioned. Then researchers started
noticing that a lot of the evidence they were studying – the iridium, the quartz, the glass
– was all concentrated in North America, so they focused their search, using new technology,
like satellite imagery and scans that measure the density of rock beneath the surface, and
in 1991 they found what they were looking for – a giant crater just off the coast of
Mexico’s Yucatan Peninsula, about 180 kilometers across – about the size you’d expect a 10
kilometer asteroid to make, and marked by huge disruptions in the layers of rock at
about 66 million years ago. It was named after the nearby town of Chicxulub, and that is
how the biggest piece of the puzzle came together – the Asteroid Impact Theory, also known as
the Alvarez Hypothesis. So, like I said, this theory checks off a
lot of the boxes when it comes to the evidence we have. Explains the abundance of iridium in the rocks?
Check! Accounts for the drastic and sudden change
in climate? Check! Was capable of killing 50% of life on earth?
Double-Check! So the rest is history – by which I mean it
became accepted as historical fact, and it’s the quick and easy answer to the question
of what killed the dinosaurs. Now, you’re not going to find many scientists
who say that there was never any impact or that the theory is totally off-base, but there
are many who think that there were other factors at work and that the extinction might well
have started before, and the asteroid came to finish the job. It turns out, for instance, that the impact
occurred in the middle of the most severe volcanic activity Earth has ever seen. India
is home to one of the largest lava flows in the world, with volcanic rock covering an
area the size of France and, at some places, nearly two and half kilometers thick. These
formations are known as the Deccan Traps, and they were formed by a series of mind-blowingly
huge eruptions that scientists think began about 500,000 to a million years before the
Yucatan Impact, and kept going for hundreds of thousands of years afterward. Such violent, prolonged eruptions would have
had an unmistakable effect on the climate, sending ash and dust into the atmosphere,
obscuring sunlight, killing vegetation, and altering weather patterns around the world.
And, sure enough, fossils show changes in things like microscopic marine life that suggest
a steep dive in temperature before the impact by as much as five to eight degrees Celsius. Now the big-picture impacts of this kind of
climate change, whether it was caused by volcanoes or an asteroid, are probably pretty obvious,
but the thing is we’re not sure how exactly this led to the dinosaur wipe-out. For instance,
despite the fact that we think of dinosaurs as reptiles, they probably weren’t cold blooded,
but from what we can tell about their physiology, they weren’t warm blooded like modern birds
either. So they might have been somewhere in between, or different types of dinosaurs
could have had different types of metabolisms. In either case, they weren’t able to adapt
as well or as quickly to changing temperatures as mammals or other kinds of animals. Another problem dinosaurs likely suffered
was simply their own success. They were by far the largest animals on land, and lots
of fossil beds suggest that sometimes they lived in dense populations. So dinosaurs were
probably competing with each other for food, water, and territory by the time the curtain
started to fall. Throw in a tiny little variable, like a 7
degree change in temperature, and you can see how things would fall apart pretty quickly.
While some dinosaurs might have given in pretty quickly to the cold, the plant eaters may
have dwindled more slowly as huge swathes of plant life started to disappear, and then
without any herbivores to prey on, the meat eaters began to vanish. But that’s just one scenario; in addition
to volcanoes exploding and space rocks hurtling toward us, it also seems that the oceans were
disappearing, not because of changes in climate but because of changes in the plates of the
Earth’s crust. Again, about 65 million years ago, the usually dynamic rifts where plates
meet under the ocean floor began to stagnate. It’s like the plates just stopped moving,
and once they stopped, those rifts began to settle, sinking down into the earth’s mantle.
As the sea floor dropped, ocean levels dropped with them. This phenomenon, known as marine regression,
completely changed the map of the Earth. Inland seas, like the one that used to run through
the middle of North America disappeared, and more than 28 million square kilometers of
land suddenly became exposed in less than 100,000 years. Marine regressions don’t happen
often, but when they do, they are usually linked to extinction events because not only
do they remodel life on land, turning shorelines into planes and lakes into deserts, they also
wreck everything for aquatic life. Marine regressions cause big changes in ocean
depth and temperature and can create huge oxygen-poor dead zones. This is probably why
fossils show enormous die-offs in plankton, for instance, tens of thousands of years before
the Chicxulub impact. With these centers of the food web gone, it makes sense that other
saltwater creatures like sharks and rays and corals, and reptiles like mosasaurs and plesiosaurs,
would not be far behind. Again, it could have played out in a number
of ways, and in a way, it’s kind of fun to consider all the different scenarios. Like
if the Chicxulub impact never happened, the world would be a very different place1 We
might still have a world with pterosaurs and armored trees and me riding a triceratops
at the rodeo. I definitely wouldn’t do that, let’s be honest. I don’t even want to ride
a horse, a tame, docile, old horse, I’m like “Oww, no.” But if there were no asteroid, a lot of dinosaurs
and marine life would probably be gone anyway. In that case, the Chicxulub impact may have
just been the last nail in the coffin – something that turned an already really hard day into
one of the worst days in the history of the planet. The point is, we still don’t have one single
answer to what caused the K-Pg extinction event, though we generally talk about it like
we do. But the more clues we tease out of the ground, the better we’ll be able to understand
what can cause such a diverse group of animals that once ruled the earth to all but disappear. Thanks for watching this SciShow Infusion,

    The problem with saying the earth is millions of years old is that there should have been hundreds of thousands of these asteroid impacts. Not just 1..which just so happened to eliminate all the dinosaurs and nothing else. Just sounds super silly. Almost as bad as Noah's ark. But I guess that's the best thing they could come up with so they had to run with it. There just is no way all dinosaurs could be wiped out but there still be other animals living as well.

  36. Keenan Dandridge says:

    Through quantum astrology i can say it was the divine creation but life was so dense back then so we perceive it very very slowly but to the divine we came here instantly bc there is no such thing as the past or future it all exists simultaneously….so the answer is this was all suppose to happen from us to be able to have beautiful places on earth. The safest animals would evolve. people wonder about paradise or hell well they are both on earth it just depends how you perceive it. So as a collective we knew when it was time to come to earth. The message is we’ve already made it as far as we can in the 3rd density and just need to align with whatever life we want bc beliefs create reality but the most important thing to know is that we are vast spiritual beings that put a piece of our energy in this physical dimension but have it spread out it millions of other dimensions.

    Hold up… Just a thought, but convection in the earth's mantle both moves the tectonic plates and creates the earth's magnetic field which helps deflect solar winds. So, during a period in which that convection has slowed down enough to cause severe marine regression, wouldn't the earth's magnetic field have been significantly weaker? Might that have contributed to the extinction as well? Also, I know our magnetic field doesn't deflect large objects, but is there any research suggesting that it could influence the trajectory of large, metallic meteors?

    What Happened to the Dinosaurs?

    “PALAEONTOLOGY is the study of fossils, and fossils are the remains of life from past ages.” But as one paleontologist said, it is “a highly speculative and opinionated science.” This is evident regarding dinosaurs. Listing some speculations as to what happened to them, Princeton scientist G. L. Jepson stated:

    “Authors with varying competence have suggested that dinosaurs disappeared because the climate deteriorated . . . or that the diet did. . . . Other writers have put the blame on disease, parasites, . . . changes in the pressure or composition of the atmosphere, poison gases, volcanic dust, excessive oxygen from plants, meteorites, comets, gene pool drainage by little mammalian egg-​eaters, . . . cosmic radiation, shift of Earth’s rotational poles, floods, continental drift, . . . drainage of swamp and lake environments, sunspots.”​—The Riddle of the Dinosaur.

    It is apparent from such speculations that scientists are not able, with any certainty, to answer the question: What happened to the dinosaurs?

    Sudden Extinction Theory

    A more recent theory was put forth by a father-​and-​son team, Luis and Walter Alvarez. Walter Alvarez discovered, outside the town of Gubbio in central Italy, a curious thin, red layer of clay sandwiched between two limestone layers in the rock formation. The lower layer of limestone yielded an abundance of fossils. The top layer was almost devoid of fossils, leading the geologists to conclude that life suddenly disappeared and that the thin, red layer of clay had some connection with the extinction.

    Analysis revealed that the clay was rich in iridium (a metal), 30 times richer than the concentration normally found in rocks. They knew that such high concentrations of this rare element could come only from the earth’s core or from sources outside the earth. They concluded that the iridium was deposited by a huge asteroid that hit the earth, causing the sudden extinction of the dinosaurs.

    After the discovery of the iridium-​enriched clay at Gubbio, similar deposits were found in other parts of the world. Did this corroborate the asteroid hypothesis? Some scientists remain skeptical. But as the book The Riddle of the Dinosaur acknowledges, the Alvarez hypothesis added “fresh yeast to the study of extinction and evolution.” And paleontologist Stephen Jay Gould admits that it could diminish “the importance of competition between species.”

    Commenting on this new theory and the apparently sudden extinction of the dinosaurs, one science writer admits: “They could shake the foundations of evolutionary biology and call into question the current concept of natural selection.”

    University of Arizona scientist David Jablonski concludes that ‘for many plants and animals, extinction was abrupt and somehow special. Mass extinctions are not merely the cumulative effects of gradual dyings. Something unusual happened.’ Their arrival was also abrupt. Scientific American observes: “The sudden appearance of both suborders of the pterosaurs without any obvious antecedents is fairly typical of the fossil record.” That is also the case with dinosaurs. Their relatively sudden appearance and disappearance contradicts the commonly accepted view of slow evolution.

    The Dating of Dinosaurs

    Dinosaur bones are regularly found in lower earth layers than are human bones, leading many to conclude that they belong to an earlier time period. Geologists call this time the Mesozoic period and subdivide it into the Cretaceous, Jurassic, and Triassic periods. The time frames used for these periods are on the order of tens of millions of years. But has this been established with any certainty?

    One method being used to measure the age of fossils is called radiocarbon dating. This dating system measures the rate of decay of radioactive carbon from the point of death of the organism. “Once an organism dies, it no longer absorbs new carbon dioxide from its environment, and the proportion of the isotope falls off over time as it undergoes radioactive decay,” states Science and Technology Illustrated.

    However, there are severe problems with the system. First, when the fossil is considered to be about 50,000 years old, its level of radioactivity has fallen so low that it can be detected only with great difficulty. Second, even in more recent specimens, this level has fallen so low that it is still extremely difficult to measure accurately. Third, scientists can measure the present-​day rate of radioactive carbon formation but have no way of measuring carbon concentrations in the distant past.

    So whether they use the radiocarbon method for dating fossils or other methods, such as employing radioactive potassium, uranium, or thorium, for dating rocks, scientists are unable to establish the original levels of those elements through ages of time. Thus, professor of metallurgy Melvin A. Cook observes: “One may only guess these concentrations [of radioactive materials], and the age results thus obtained can be no better than this guess.” That would especially be so when we consider that the Flood of Noah’s day over 4,300 years ago brought enormous changes in the atmosphere and on earth.

    Dartmouth College geologists Charles Officer and Charles Drake further add doubt to the accuracy of radioactive dating. They state: “We conclude that iridium and other associated elements were not deposited instantaneously . . . but rather that there was an intense and variable influx of these constituents during a relatively short geologic time interval on the order of 10,000 to 100,000 years.” They argue that the breakup and movement of the continents disrupted the entire globe, causing volcanic eruptions, blocking sunlight and fouling the atmosphere. Certainly, such disruptive events could change radioactivity levels, thus distorting results from modern-​day radioactive clocks.

    The Genesis Account and Dinosaurs

    While the radioactive dating method is innovative, it is still based on speculation and assumption. In contrast, the Bible account in the first chapter of Genesis simply states the general order of creation. It allows for possibly thousands of millions of years for the formation of the earth and many millenniums in six creative eras, or “days,” to prepare the earth for human habitation.

    Some dinosaurs (and pterosaurs) may indeed have been created in the fifth era listed in Genesis, when the Bible says that God made “flying creatures” and “great sea monsters.” Perhaps other types of dinosaurs were created in the sixth epoch. The vast array of dinosaurs with their huge appetites would have been appropriate considering the abundant vegetation that evidently existed in their time.​—Genesis 1:20-24.

    When the dinosaurs had fulfilled their purpose, God ended their life. But the Bible is silent on how he did that or when. We can be sure that dinosaurs were created by Jehovah for a purpose, even if we do not fully understand that purpose at this time. They were no mistake, no product of evolution. That they suddenly appear in the fossil record unconnected to any fossil ancestors, and also disappear without leaving connecting fossil links, is evidence against the view that such animals gradually evolved over millions of years of time. Thus, the fossil record does not support the evolution theory. Instead, it harmonizes with the Bible’s view of creative acts of God.
