Imagine you're a dinosaur, let's say an Alamosaurus,

The sun has set and you're minding your own business,

just lumbering around an area that will eventually

be called Austin, Texas, when something glowing in the sky

You're not too concerned, but you keep an eye

on that weird glowing star for a couple of hours anyway.

The thing is, that star keeps getting brighter,

but it doesn't seem to be moving, so you forget about it.

Then out of nowhere, around 60 hours later,

you feel the thunderous boom of a supersonic shock wave.

That thing you hoped might be a routine shooting star

is actually an asteroid around 6 miles wide--

Before you can even think "what the hell was that?"

the thing you thought was a star 60 hours ago plunges

18 miles into the Earth, and you die immediately.

Now, onto the disastrous event which some scientists say

nearly demolished Earth before it even really had a chance

The Chicxulub asteroid slammed onto the coast of Mexico

and killed just about everything on Earth.

The first thing Earth felt before the Chicxulub asteroid

it blasted a hole through the Earth's atmosphere,

Naturally, ground zero absorbed the asteroid shock wave first

with a sudden spike in air pressure, which

ruptured lungs and other internal organs of every living

Not long after you, the leaf-eating Alamosaurus

the 6-mile wide asteroid plunged onto the shore of what we now

refer to as the Yucatan Peninsula, which is

Immediately after the asteroid-- which, by the way,

smashed into the rim of the Gulf of Mexico,

rose higher than Mount Everest before it broke apart and fell

The energy produced from the impact of the explosion

was equivalent to 100 trillion tons of TNT,

of atomic explosion you're familiar with-- you know,

Instead, the impact looked more like a rooster tail made up

A lot of the molten debris was several times hotter

than the surface of the sun, and it set fire to everything

kicked back 25 trillion metric tons of rock ash

and shot debris into the Earth's atmosphere.

An inverted cone of liquefied molten rock

The heat turned the molten rock into little red hot beads

Scientists call them tektites, and after they

Jan Smit, a retired professor of sedimentary geology

from Vrije Universiteit in the Netherlands,

who is considered the world expert on tektites,

and says the fish got it the worst from the tektites

with their mouths open, gaping, and in this net,

they catch tiny particles, food particles,

in their gill rakers, and then they swallow, like a whale

That means that the first direct victims of the impact

of a Triceratops and a duck-billed hadrosaur

proves beyond a doubt that dinosaurs were still

It's theorized that it rained the very same tektites

for nearly an hour, and set everything that
