At last, Synapsids, my favourite ancestors...

[dracodracarys]

The awkward moment when people call Dimetrodon a dinosaur, even though it's about as related to dinosaurs as primates are to turtles

1:08 People: "What’s your favourite prehistoric animal?"

Me: *"Cheese."*

[savharris]

It's almost unfair that we won't ever even begin to know everything, that potentially spent millions of years playing out it's own unique role in this existence, that we all probably just "lucked" into.

[antigangsterz]

Synapsids like Kannemeyeria and Cynognathus also lived alongside the first dinosaurs.

Dimetrodon died out about 30 myr before the Dinosaurs, not 40 myr as thought.

What a beautiful channel. I get off work. Smoke me a blunt and get educated. LIFE.

I really enjoyed this thoughtful overview of synapsids. Many thanks.

these creatures are damn AMAZING so is the visualization

[flightlesslord]

I feel like estemmenosuchus and animals with similar boney structures probably had some kind of soft tissue thing going on, maybe a resonating chamber, maybe even something reminiscent of a trunk. There's alot of things like this in the fossil record, imagine if we didn't know what dugong, or hippos or elephants looked like, but found fossils. With all their unique soft appendages and organs and stuff, we'd depict them quite differently if we just had bones

[filmboyultimate]

I wonder what mammals would look like if the great dying never happened

[kat_astrophe]

Love the use of footage from Walking With Monsters. So nostalgic

[carolynallisee]

A good video, except for one thing. Grass is a flowering plant. Flowering plants didn't evolve until the Cretaceous Period. Therefore there is no way that  Placerias, a Triassic animal, could have eaten grass.

I think I would rather see what the earth was truly like hundreds of millions of years ago than see if there is life on other planets or if there is anything after we die.

Thank you so much for the chapters! super helpful!!!

[exoticlonghair]

increible que haya habido mamiferos o casi mamiferos antes que los dinosaurios, en cierta manera somos mas "antiguitos" que ellos, no entiendo como estas criaturas no tienen mas propaganda igual que los dinos, los gorgonopsidos y dimetrodontes son increibles, mis bestias prehistoricas favoritas junto con los raptores, tiranosaurios, pliosaurios, reptiles voladores, y aves del terror, me encantan los carnivoros ¿se nota o no?.

[xenoidaltu]

You forget the Therocephalians!

1) Euchambersia: The carnivore with a venomous bite!

2) Lycosuchus: Cool looking double canines!

10:15 Kannemeyeria = Kannemeyer's one. Named after South African medical practitioner, naturalist, archaeologist and palaeontologist Daniel Rossouw Kannemeyer (1843-1925), who discovered the original specimen of Kannemeyeria simocephalus in the second half of the 19th century, presenting them to the public in 1884.

You should use this computer voice more often, easily the best one

[strzygon]

10:32-10:34 wait hang on, did he just say eating grass?
Hold up, grass didn't evolve even towards the cretaceous period, how the hell would grass exist in the Triassic, let alone the Permian?
something's fishy here.

[flightlesslord]

Those are some nice and accurate looking bois
