1
A ruthless murder was committed.
2
Someone killed the dinosaurs, and we have the murderer.
3
Witnesses say that an Everest-sized asteroid hit Earth,
4
devastated the planet and caused a mass extinction.
5
A simple, fascinating and convincing explanation.
6
Or is it?
7
In the last few years,
8
new evidence has reinvigorated an older theory pointing at a second suspect.
9
A very slow and liquid asteroid,
10
1,000 times bigger, hitting Earth on the opposite side of the planet.
11
Like the true crime channel we are,
12
let's look at the new evidence and tell a different story that could change everything we thought we knew.
13
The last days of a kingdom.
14
66 million years ago, Earth was barely recognizable.
15
It was the last days of the Cretaceous,
16
one of the hottest periods in Earth's history, and much more humid.
17
Lush jungles and woodlands covered much of the planet.
18
Even the polar regions were home to forests of prehistoric pines and ferns.
19
Amazing ecosystems that were robust enough to survive the many months of darkness during the polar night.
20
Oversized animals were everywhere.
21
Pterosaurs filled the skies.
22
Marine lizards and long-necked monsters up to 15 meters swam in the oceans.
23
And on land, basically everything larger than one meter was a dinosaur one of the most successful animals ever to walk Earth,
24
dominating the world for more than 150 million years.
25
And then they were murdered.
26
All these majestic creatures vanished in a split second of geological time.
27
Why?
28
Yes, it is true that around that time a big asteroid hit Earth.
29
But was this actually what killed the dinosaurs?
30
Or did it arrive just in time to get all the blame?
31
Because according to some recent science,
32
just before the asteroid struck,
33
an ancient nightmare, older than even the dinosaurs,
34
decided to destroy the world.
35
Let's look at how it might have done it.
36
The Beast Slowly Awakens The ancient continents almost resembled the world of today, but not quite.
37
India was still a continent-sized tropical island,
38
full of lush rainforests and exotic life on its way to smash into Asia.
39
But this paradise also hosted something else.
40
The Deccan Traps, a volcanic region a thousand kilometers wide and about to come to life in a dramatic fashion.
41
The apocalypse began quietly and silently.
42
About 800,000 years before the impact,
43
the Deccan Traps began to exhale about 10 million tons of CO2 and sulfur dioxide each year.
44
Which in the grand scheme of things was not that much,
45
so for a long time no one noticed.
46
The problem was, these emissions wouldn't stop.
47
For half a million years,
48
they started to dangerously pile up in the atmosphere.
49
About 300,000 years before the asteroid,
50
the Deccan Traps started to vomit lava.
51
This was nothing like a normal eruption.
52
It was a lava flood.
53
Imagine a landscape with volcanoes stretching beyond the horizon.
54
They were constantly active, releasing a steady flow of massive amounts of poison and lava,
55
interrupted by much more violent and deadly eruptions.
56
The lush paradise of India was the first victim as gigantic clouds spread toxic fumes and poisoned the coastal regions.
57
Clouds of ash darkened the sky as rivers of magma started massive wildfires,
58
eradicating many local ecosystems and paving the continent with dead dinosaurs.
59
Still at this point, it all looked like a local catastrophe,
60
one of many that have hit our planet over its billions of years of history.
61
Had it stopped here, there might still be dinosaurs today.
62
But the nightmare hadn't even begun yet.
63
The beast turns furious.
64
The Deccan Traps would just not stop spewing lava.
65
And so, after hundreds of thousands of years of never-ending volcanic emissions,
66
the catastrophe became global.
67
First, the planet experienced a wave of heating,
68
with oceans getting at least 2 degrees Celsius hotter in just 100,000 years.
69
Which is bad, but just about the time frame that leaves ecosystems a chance to adapt.
70
But then, nature would pull a cruel prank.
71
Some of the gases of the Deccan traps heated the planet up,
72
while others cooled it down.
73
But the mix was uneven,
74
so after the initial warming,
75
a period of cooling followed,
76
followed, massively stressing the ecosystems that barely managed to adapt to the hotter temperatures.
77
At the same time, the sulfur in the atmosphere came back down as acid rain,
78
while the CO2 was acidifying the oceans and killing the plankton,
79
which was, and still is today,
80
the basis of the food web in the oceans.
81
And if plankton disappears, a massive extinction is all but guaranteed.
82
But now, the grand finale was about to begin.
83
About 50,000 years before impact, the true apocalypse came.
84
Like a cosmic horror breaking out of its prison,
85
the Deccan Traps roared and screamed
86
and began to spew out tens of trillions of tons of magma
87
and even more deadly gases in an onslaught that lasted for several thousand years,
88
rolling over ecosystems, devastating everything they reached.
89
For a time as long as all of human civilization,
90
this lava Armageddon brought massive wildfires.
91
Earthquakes and tsunamis smashed and shook the continent.
92
So much heat was released from the roaring hot interior of our planet that it might have created hypercanes,
93
cyclones tens of kilometers wide with winds reaching almost 1,000 kilometers an hour,
94
three times more than the deadliest hurricane ever recorded by humanity.
95
These storms were so massive and intense
96
that they could reach tens of kilometers into the stratosphere
97
and rip holes into the ozone layer with devastating consequences for all life,
98
now without protection from the sun's radiation.
99
And of course, where the hyperstorms occurred,
100
devastation and death would follow.
101
And as if all this wasn't enough,
102
out of the guts of the earth came colossal amounts of venom.
103
Giant clouds loaded with mercury and hydrochloric acid rolled over the planet,
104
delivering the final blow to the remnants of a once magnificent and fertile world.
105
As food chains crumbled and the whole world around them collapsed,
106
some of the last dinosaurs to ever walk the earth may have died vomiting toxic foam while being bathed in acid rain.
107
A cruel end for for the members of a noble family that had ruled the world for so long.
108
Then it just ended.
109
The frenetic eruptions slowed down and the endless natural disasters began to fade away.
110
But the world was changed forever.
111
The monster had left unfathomable devastation and corpses in its wake.
112
Even the planet's ecosystems far away were severely wounded.
113
It was the end of a whole geological era.
114
A murder that started slowly and then turned loud and violent.
115
And then it happened.
116
Like a cosmic joke, on the other side of the world,
117
a bright dot of light appeared in the sky.
118
And an instant later, an asteroid 10 kilometers across smashed into Earth with the power of 4 billion atomic bombs.
119
If you want to see what this was like,
120
we made a whole video about it.
121
If life on Earth was like a murder victim barely holding on,
122
this was the final blow.
123
Just too much.
124
After the massacre on the other side of the world,
125
the Deccan Traps went on expelling tens of trillions of tons of deadly gases for another 800,000 years,
126
making sure the devastated planet stayed covered in poison.
127
When they eventually finished and truly went back to sleep,
128
75% of all species on Earth had perished.
129
Most famously, almost all dinosaurs.
130
Except birds, the only dinos that are still with us today today.
131
Their stunning beauty and diversity are a shy reminder of how majestic and wonderful their larger cousins must have been.
132
So, who was the murderer?
133
Were the dinosaurs doomed by the traps,
134
or would they have survived without the asteroid?
135
Was it teamwork?
136
Well, we don't know.
137
Scientists have been fiercely debating this question for years,
138
but for now we have no definite answer.
139
The timeline of events
140
that we've shown here is based on some of the most recent reconstructions of the evolution of the Deccan traps.
141
There are other ones that paint a different picture,
142
but right now scientists are still fiercely arguing over this.
143
Check our sources to learn more.
144
So, like much of true crime,
145
we can't end this story with an easy and satisfying resolution.
146
Time has the nasty habit of erasing evidence,
147
so maybe we'll never really know.
148
But there is something else hidden in the dust, something truly terrifying.
149
As we learn more and more about the past,
150
we've found
151
that at least four of the five Five big mass extinctions
152
happened at the same time as the Earth was furiously spewing gargantuan amounts of magma.
153
The monster that might have killed the dinosaurs seems to be a serial killer.
154
The worst massacre ever, the Permian mass extinction 250 million years ago,
155
was caused by the Siberian Traps,
156
a hellish flood of lava that killed 95% of all the species on Earth,
157
almost bringing life to its knees.
158
Still recently, many scientists thought that this was an outlier,
159
but new evidence suggests it may have been the rule.
160
Other big mass extinctions happened when the monster awoke from its sleep,
161
and the longer and more violently it rampaged,
162
the more slaughter we can see in the fossil record.
163
So maybe the dinosaurs were not massacred by a casual murderer from outer space,
164
but by a serial killer hiding beneath our feet.
165
Do you need to worry about all of this?
166
Definitely not.
167
While the monster is real,
168
it's amazingly slow and currently very sleepy.
169
If it were about to awaken again,
170
scientists monitoring the Earth's interior would get a warning really early,
171
maybe even millions of years in advance,
172
time enough to prepare and move out of the way.
173
Enough about mysteries of the past and onto puzzles in the present.
174
We're testing out this project crate from our sponsor KiwiCo today.
175
They offer fun crates for kids on topics like science,
176
mechanics, biology, and even things like ice cream making and, yes, dinosaurs too.
177
Each one is like a little adventure in a box that lands on your doorstep,
178
either individually or as a subscription.
179
And each box comes with all of the supplies you need along with kid-friendly instructions to help guide the way.
180
So, what do we have here?
181
A puzzle maybe?
182
No, a robot crab.
183
Well, go ahead, assemble it.
184
Good job!
185
This is a project that lets you build a robot yourself
186
and gives you lots of background info on the ins and outs of how it works.
187
We wanted to work with KiwiCo because they spent hundreds
188
and hundreds of hours on fine-tuning and testing their products just like we do on our videos.
189
There are more than 2,000 projects available for kids of all ages.
190
Yeah, don't worry, you count as a kid at heart.
