History of the Earth Part 3: Phanerozoic Eon – Mesozoic Era

We are working our way through the Phanerozoic eon, and we got through the Paleozoic era. Next up, the Mesozoic era! In this era we see the rise and fall of the dinosaurs, those beloved beasts. How did this come to pass? What can we say about Earth's topography during this time? Let's take a look!

I’m really glad that you described in full detail the effects of the asteroid impact at the end of the Cretaceous, instead of vaguely stating “most life and all non-avian dinosaurs died, but now there are mammals”. Great video!

Two mass extinctions in one video! Professor Dave knows how to pack a punch! Very enjoyable. Your content keeps getting better and better. Thanks for you and your team's hard work.

This may be my favorite series you have done

The way humanity is such a tiny blip in the life of earth always gets me

[justjen]

Love the series. Please consider breaking it all down to smaller bits of time and explaining more.

[chemdog]

Those CGI dinos always remind me of growing up in the 90s when everyone was obsessed with Jurassic Park. Good stuff Prof. Dave!

Prof dave, what makes you choose these topics? You seem to know a lot and I mean a lot of fields and have been producing content for years. I am grateful for your dedication and passion.

Amazing that asteroid impact destroyed 80 percent of life and yet isn’t nearly the biggest extinction event in earths history

[jjwrenmusic]

Isn’t it true that many small dinosaurs survived this mass extinction? And they are the ancestors of today’s birds? I’m probably misunderstanding something.

I love that Professor Dave is the default of Youtube when I don't change to another video. Arigato Sensei, I'm a little smarter today than I was yesterday. Most respectful bow to Sensei.

"Trouble was brewing in Siberia" - A euphemism used in Russia where the diet is heavy on beer, caribou, and onions.
(Massive escapes of noxious gasses associated with the eruption of a mantle plume - I know that feeling)


Not really, I made it up. But it should be.

Thank you so much about this series, it's awesome

While the chart showing the various eons, eras, periods, and epochs is very informative and accurate, it does distort the relative time frames. I’d love it if you also point out that while the 63 million years of the cenozoic takes up the most space on the chart, it is actually quite small compared to the other periods.

Trouble brewing in Siberia- extremely understated 😂

I'm really enjoying this series! Thanks for all you do. ❤❤

Dave: All dinosaurs died.
Birds: Am I a joke to you?

The Mesozoic is amazing, and always fascinated me.
