Thanks so much with the information

Can you record an updated version of this lecture next time you give it? I like to compare academic lectures on the same topic across time to see how our understanding of things evolve

Scutosaurus is a parareptile

They don’t look very anesthetized

me too love them

You state in here that early archosaurs are expected to exothermic because crocodylians are yet the explanation for the advanced heart in crocodylians is endothermic ancestors Edited for typo

Hey! You leave Lystrosaurus alone! Our ancestors probably benefitted from their burrows. They even found animals taking shelter in their burrows with them, whether they were in there sheltering together or one died and another took shelter not clear, but still, I think of them as the capybaras of the PTE and early Triassic.

So grateful for this amazing series of lectures. Wondering if you may have any ideas if there are similar available for Australia? Thanks so much!

Great video!

Wonderful. You mention a video of ornithischian chewing, here is one kzbin.info/www/bejne/eKLHnomghL56a9k&pp=gAQBiAQB

Useful for me. Thanks

One of the silver lining of the pandemic is the free lectures on youtube :D - thanks for making these public

I’m back! I love listening to these lectures. I hope it’ll help during college. Yay dinosaurs, yay evolution, what a beautiful example of the work of God!

About the Cambrian explosion, I believe that the reason is mostly genetic. The genome of organism was unstable for some time before mecanism evolved to stabilize the genome. So lots of new organism could evolve when predator arise and higher oxygen concentration in the environment.

I'm an engineer but this class of interesting Earth sciences will probably help me when brainstorming a new design. I love the brilliant ''engineering solutions'' of life as it evolve.

Excellent. Thanks.

39:15 That cartoon with the fish standing outside there bowl that is caught on fire. I remember that cartoon from 25 years ago. And it was called "The "Farside." A very funny comic strip.

As our own weather starts to manifest new extremes, I'm getting a fresh perspective on The Great Dying. It's not just really hot with acid rain caustic enough to damage eyes and maybe even skin. Weather extremes like we're just starting to see, but far worse, would be augmented by the volcanic gases and metals emitted by flood basalt eruptions or leeched out of the ground by acid rain. Imagime severe acid rain and flood events and hurricanes. Or, during droughts, firenadoes kicking up heavy metals, sulfur and chlorine like the chemical weapons of WWI turned into weather bombs. Mudflows and landslides and boulder storms like the one that hit Montecito, California about 5 years ago (look up the YT video "The Night it Rained Boulders") would be common... I seem to recall one bit of research that all the rivers on Earth seem to have reverted to their pre-vegetation state, losing their meanders and charging downhill in boulder-filled ravines in a straight line. And ponds, lakes and marshes would be sour, stinking, and often poisonous, since hot standing water tends to lose its oxygen and become fit only for anoxic bacteria. it really is amazing that anything (especially plants) survived.

These are great, in case you ever find yourself wondering.

I just found your channel and already am finding your lectures fascinating. I am learning so much! Thank you for posting these.

Wtf is a supposed science teacher doing talking about "Jesus"???

There has been other times when we had 100 plus temps for long periods of time when there were no cars on the road like in 1909 this has nothing to do with fossil fuels

99.9% of life going exitinct ? The Permian/Triassic extinction event did not result in this level of extinction

There is a slight misconception about the VEI measurement though, but a very common one even among scientists: VEI only really applies to volcanic explosions, not to effusive eruptions in general. It is always tempting and very intuitive to only measure the volume of lava and scale it on the VEI, but this doesn't really work - the actual VEI measurement takes account of the height of the ash columns, which makes little sense with a LIP accounting a very long period of mixed eruptions, mostly effusive. We need a new intuitive and potentially popular index for volcanic eruptions ^^' Now I understand that using the VEI reference that way makes it a very good vulgarization tool, but then the vast majority of people have the wrong idea about what the VEI measurement actually is.

Fantastic work, I already watched this lecture three times along the years.

Ranting in my head about conflating reptiles with amniotes thus making mammals also reptiles. We don't need another 'well actually, birds are reptiles,' situation. I'm a firm synapsid respector.

Brilliant! You're a hugely valuable resource. Many thanks. (my writing coach said never use exclamation points but in this case, it's a must)

Jacksonville Florida is 25 billion square feet. You can fit everyone on the planet in jacksonville over three times

Are they invasive?

when are going to tell these brainless gullible fools how the river pebble evolved into a basketball ?

About 36:00: Great landscape!

All Earth Mordor...

About 10:05: I once heared that those of the arthropods which could fly (like giant dragonflies) survived into the Permian because they got more oxygen than flightless ones.

Now I understand Yellowstone and global warming it's nothing we can control

Armored cows. A lot of tongue action is all I’m imagining from these weirdos

what's a nitch space?

I wish you would not speak in the present tense about the past. It is too disorienting, about what happened . But of course your agenda is to frighten your listeners about what humans are doing to the climate, and that is not your job. Imagine having to listen to such propaganda while trying to listen to science. You've lost me.

I can't hear you.

What happened to the volume?

You're a great lecturer! Thanks for doing these

Bottom smasher

Thanks bro

Can't hear the lecture, let alone the student questions.

@thomas Evans what is the most interesting fact about fishes?

“You’re both good and evil at different times.” 11:55 Preach! Really important observation to make, thank you. I’ve seen firsthand fine people or groups of people villainized in a classroom setting by the teacher. Excellent insight to share with the kids.

Just Imagine If I Wish Humans Coexisted In The Carboniferous Period

Humans see red - that is the unusual thing for mammals

Stupid students

Thank you. I’m a museum guide at AMNH in nY. I’m talking to the public. Your talks are wonderful

Very interesting this topic
