Correction! At 9:19, we erroneously refer to Dimetrodon as an herbivore. It was definitely a carnivore. We even made a whole video about Dimetrodon and their carnivorous ways in a previous episode: kzbin.info/www/bejne/iYOWgIKGbtJ8o6s Thanks to everyone who pointed out our error!

The problem there is that neither of thise structures fossilize well, so what is known is from the very rare fossil find and extrapolating from what is there today.

[@puncheex2]

What's a sub-fossil? The "Ida debacle" was a museum-media hype-money mistake, not an event that said anything about the paleontology. But, yeah, primates.

[@LemurWhoSpoke]

puncheex2 "Subfossil" means younger than younger than 50k years. Basically not old enough to have become rock. Pleistocene megafauna fall into this category, but few shows have ever talked about the giant lemurs, which are called "subfossil lemurs" in the literature. As for Ida, there was a lot to be learned from that debacle. Basically a small group of paleoanthropologists was trying to push an outdated view on the evolution of primates. The reason it took off wasn't just because of the chance to make money. The outdated view of primate evolution is still very much alive and can be see all over signs in zoos and in some general textbooks. Basically they tried to claim that Ida was a lemur, and a missing link between lemurs and anthropoid primates. No such missing link exists because anthropoids didn't evolve from lemurs. In fact, this is tied to an even bigger upheaval in our understanding of primate evolution. Primates did not originate in Africa; they came from Asia. In fact, the earliest fossils in Africa had long been labeled as anthropoids (by the same group that gave us Ida), but have recently been shown to actually be stem strepsirrhines. The early monkeys first started evolving in Asia and were probably nocturnal, whereas the lemur ancestors evolved in Africa and were diurnal. That's big, and an episode should be devoted to it.

[@puncheex2]

OK, thank you for the courteous re[lies. I appreciate the education you have given. I agree that this would be a very good topic for Eons to spend some time on.

[@LemurWhoSpoke]

I love you mention the trilobites. I have a trilobite collection! They are amazing creatures and is it weird that I find them adorable?

[@mezo4010]

Nope.

[@nicolel.2398]

Dude trilobites are the cutest things that ever happened. I love them so much.

[@EvilSnips]

Yessss :D I have seven trilobite fossils xD Most of them are actually really cheap, so it is easy to start a collection. Just go to a local rock shop.

[@nicolel.2398]

That’s radical man, I love it. I’m in college for paleontology so I have some wonderful outlets for trilo purchasing ❤️

[@EvilSnips]

Paleontology sounds like a fun major to take. I have been considering it, but it's a lot of field work from what I have seen.

[@Argethebarge]

Love it. Glad that you guys try to keep people engaged in palaeontology!!

[@ericanderson1846]

Spectacular explanation. More of this, please.

[@maidros85]

Holiday is when that KZbin bell brings you a notification of a new Eons vid. 💕

[@BRUtahn]

What an awesome video! I love how you guys help put things in perspective!

[@robyn00xx]

This is my favorite channel to watch after a few bong rips

[@bjarkiengelsson]

No kidding!

[@CompBioQuest]

I love the illustrations and storytelling. Thank you

[@yvonnerogers6429]

I’m loving this channel. Thanks for all your hard work! I learn so much! I wouldn’t mind a video like this covering the Cenazoic from the Paleocene through the Pleistocene as I find that stretch of time doesn’t get covered much, either, at least not as much as the dinosaurs’s era. By the way, the soundtrack for this episode is beautiful! Kudos!

[@danm7298]

I love learning about how life evolved from basically nothing to where we are now and where we are going. It really trips me out

[@moiraandnica4798]

I really enjoy your channel! I even let my kiddo watch with me! Thanks for explaining things like this, really appreciate y'all. ^_^ :) :)

[@wade5941]

Nice video and well done. I have always found it interesting that the Cambrian explosion of life occurred during a period of Earth's history that coincided with CO2 levels of approx 4000 ppm and temperatures 15 degrees C warmer than today. It is also notable that temperatures have almost always been significantly warmer than temps today. As she said, almost every major group of animals that exist today developed during the first 40 million years of the Cambrian. Suspect there was not much ice at the poles and that ocean levels were much higher than today. Also interesting that the Permian extinction coincided somewhat with historically low temperatures and CO2 levels. So many changes through time. So many variables.

[@lucasotis9525]

The music and pacing in the beginning to hype up the viewer is gold, fantastic editing

[@judychurley6623]

One of the best overview videos in the series. Gives a great picture of the period.

[@xcvsdxvsx]

IDK about the first 0:40 seconds. When I was a kid I never cared too much about the parts in my natural history books about dinosaurs. I was always infinitely more fascinated by the pages about the Pre-Permian Paleozoic but more than anything else the Cambrian. I would glance over the dinosaurs and go yea that's pretty interesting but stare for hours at the artwork about the Cambrian.

[@P-Bean]

I've learned so much more from this channel than school about this kinda thing.

[@Chris-hp9be]

"The Great Dying" sounds like an episode from Game of Thrones

[@savannaha5038]

Omg can I listen to the background song that starts at 1:40 anywhere??? I could hardly pay attention to the video the song was such a bop

[@brooklyna007]

This was so awesome! Thank you.

[@PhillipWrigley]

I have yearned for a video like this since I was a small child. Thank you! Any chance we could learn about the diplocaulus?

[@elizabethtaylor6135]

Hey LadyBones! Would you please do an episode explaining how y’all paleontologists distinguish between a fossil of a new, unknown species and just, say, a mutant(i.e. the fossil of a known species with pronounced phenotypical appearance of a few genetic mutations that did NOT prove to be most suited to their respective environments, and, therefore, did NOT propagate...)? Thank you for all the killer episodes!

[@deebee5378]

I'd like to see some information on what may have led to today's monotremes like the echidna and platypus.

[@katelynsturch3798]

I will never get tired of hearing about this

[@fadiljo4520]

What I concluded from all of this is that life always finds a way.

[@noneofyourbizznizz5375]

I'd have paid more attention in my classes if I was shown things like this more. Informative but kept interesting too.

[@jcortese3300]

I just love how the Great Lakes are just ... sitting there, as usual. :-) I wonder if having such an ancient shoreline is reflected in any characteristics of the shoreline itself?

[@rafaelrafaelrafael]

I think it's there just as a reference. From the maps, it seems it was just an deepocean valley for most part.

[@dgodfrey9189]

It's just a reference, the lakes are no older than the last ice age.

[@puncheex2]

The Great Lakes have only existed about 10,000 years, since the last retreat of the glaciers, which also helpfully carve the lake's basins. Big, sloppy, wet things.

[@jcortese3300]

Ah, gotcha. Thanks!

[@nathanielmorley3874]

Awesome! Great video, thank you very much for the video. I have an idea for a future video... "How dinosaurs and/or ectotherms adapted to the cold." Many flora and fauna have thrived in the polar regions in the past, and although they weren't necessairily as cold as they are today, there were parts of Laurasia and (mainly) Gondwana which still experienced snowfall. I believe this to be an interesting topic, and would like your take on it. Also, the episode would be fitting seeing as we are in the heart of winter...

[@brentgoodman9884]

She makes complex topics understandable! Great speaker!

[@nescaudrummer]

the album "Phanerozoic I: Palaeozoic" by the band The Ocean made me interested about the topic, so I'm checking out this video

[@joenotch7429]

Watching this video 2 years later and FINALLY someone mentions The Ocean.
