The Day the Mesozoic Died: The Asteroid That Killed the Dinosaurs — HHMI BioInteractive Video

Ever wonder why the dinosaurs disappeared? HHMI BioInteractive investigates the cause of the mass extinction at the end of the Cretaceous period—and the clues come from paleontology, chemistry, physics, and biology.

This three-act film tells the story of the extraordinary detective work that solved one of the greatest scientific mysteries of all time. Explore the fossil evidence of these prehistoric animals, and other organisms that went extinct, through this lively educational video.

Wow hats off to this photographer, he really put himself in danger taking all these shots

[Jutebox]

Man its really crazy to think about how many things that we now know as "common knowledge" used to be entirely unknown, and cutting edge discoveries. I think I've been taking that for granted.

[IsaAnders]

This is legitimately so interesting, props to my science teacher for making us watch this

[donaldpage]

One of the best documentary i have ever watched. It explains in great detail how the whole extinction event of dinosaur unfolded.

I am kind of crying right now because these selfless scientists/researchers spent almost all of their life in pursuing knowledge and knowing the unknown, contributing to society's knowledge. Through these people we were able to develop. I am really thinking that I am just an insignificant being by only thinking my own well-being.

These types of shows are what we need on TV, honestly.

"What the asteroid impact taught us about evolution is that it's not always about survival of the fittest. Sometimes it's about survival of the luckiest." Sean Carroll hit the nail on the head with this statement. Luck is a key factor in survival, not only as it applies to whole classes of animals, but to individual organisms (including humans).

I had the distinct pleasure of briefly working with Luis Alvarez in the late 70s. What a treasure he was.

I don't know what I'd do without the bearded guy explaining everything.

[sethlabratiu]

I'm an adult bro but this stuff makes me excited like when I was a kid. This was a great detective story, and a really effective, accessible documentary

[Lonewanderer]

Damn, when you think about how terrified these poor creatures were...Everything they knew was coming to an end. If something similar happens to us, few; if any, will survive.

[terrioestreich]

I love how they put together all of the clues from around the world to understand how, when and why the dinosaurs went extinct. It's amazing, thank God for smart people!!

[ragingpeppers]

We’re basically living in a post apocalyptic world

[cindyward]

I've often wondered how exactly the remaining animals survived, both during and just after the event. It must have been an extremely hazardous and difficult time.

Dinosaurs: Vibing

Some rock: Ima boutta end this mans whole career

“Without the asteroid, there’d be no us.” Great job! Thanks a lot.

[Agirmetal]

I'll tell again I've watched many videos about this subject and this is the best by a big margin

[BlueMonkeySky]

Honestly, one of the best documentaries I've seen. 👍🏻

[briantuk]

Every time I watch a simulation of dinasour extinction, I feel sad about those poor creatures
