Excellent presentation! This summer I gave a brief talk at a summer camp and my subject was the animals before the dinosaurs. I did not dumb down my talk and I covered some of this same material. Nobody, and I mean nobody, had ever heard of most of these creatures! Thanks again...
I like watching your videos about early synapsids. An interesting subject for a video would be anachronistic plants, the fossil record of these plants and their possible relationships with now extinct animals, especially the megafauna. A few possible examples I can think of are osage orange, kentucky coffeetree and honey locust. Love your videos.
Fantastic, my only complaint is the use of Mammal-like Reptile. Might give the wrong impression that synapsids are members of the outdated reptila group. I think proto-mammal or stem-mammal should be use to refer to non-mammalian synapsids.
On the subject of thermoregulation, isotope studies of some triassic genera show relatively high estimated metabolic averages associated with endothermy. Not only that, but all dicynodonts have haversian canals in their bones, which would play a major role in heat production. This would especially apply to Lisowicia, since animals with erect limb postures tend to be warm-blooded.
Thank you, Benjamin, for the lecture. One minor correction: Dimacrodon is not a dicynodont and not even closely related to them. The new evidence instead shows pelycosaur affinities for this North American (not Russian) synapsis.
Question: I’m about to start an extra credit essay for my biology class. Which of these topics should I choose: 1) How to recreate a Carboniferous environment [in a terrarium] 2) de-extincting the woolly mammoth
They both sound like fun. I guess it depends on you. Do you like hands on projects where you get to create something tangible? Or are you more cerebral, more conceptual? Because obviously you're not going to actually be able to de-evolve a mammoth unfortunately.
0:26 min I stumbled over the Pennsylvanian not beeing labeled as part of the Carboniferous in your chart. Do paleontologists use a different chart then the ICS (www.stratigraphy.org/index.php/ics-chart-timescale)?
Yes, welcome to the world of high cost books for creatures other than dinosaurs. Publishers tend to put high costs on these books because they only sell a few. Check out used copies on Amazon or other book sellers. The book goes for $289 new from the publisher: www.springer.com/us/book/9780412330803
Thank you for another interesting and informative video; what's your opinion on late surviving Dicynodonts from Australia? www.ncbi.nlm.nih.gov/pmc/articles/PMC1691326/
Jonathan Lee It could be confirmed with more compete fossils. My advisor in graduate school published an infamous paper on one from the Paleocene, which was later proven wrong; www.nature.com/articles/358233a0
Just gotta say thank you for another great video. Love your style so much! Paleontology is blessed to have wise and interested men as yourself.
Thank you love your videos.

Very impressive video!!!
See that guys? If your wardrobe matches, you can pull off a fedora.

Great topic - thanks a lot!
I love Dicynodonts, thanks for making a great video on them. Could you please do a video on the Tanystropheidae?
Lisowicia representing Synapsids against Saurapsids! 🤟😎👌

Merci beaucoup je vous felicite c est merveilleux
Question: I’m about to start an extra credit essay for my biology class. Which of these topics should I choose:
1) How to recreate a Carboniferous environment [in a terrarium]
2) de-extincting the woolly mammoth
Both sound really great! Creating a Carboniferous terrarium would be a lot of fun and a great experiment to do at home.
Thanks!
Check out codys lab on UA-cam he just recently did a video on making a Carboniferous terrarium

Paul TheSkeptic it’s just an essay. I won’t be doing any of it. Not yet at least

Their third eye reminds me of the tuatara.
Awesome video!
Question: have you done a lecture about gorgonopsians before?
I had no idea my bite was so formidable😬
Where can that book be found, aside from Amazon? The prices for that book on Amazon are expensive.

Libraries, especially inter library loans. And a copy and print place.

Thanks for getting back to me on this :)
Synapsids aren’t Reptiles, they descended from a common ancestor.
