Prehistoric Mammals ?


Everybody know their Dinosaurs But what about the creatures living in their shadows? Hop in my time machine, travel to the Meso
We’re going to pay a visit to the O.G. Mammals Meet Juramaia pretty monumental Dwelling in the trees in her high rise rental
Earliest placental before it was the trend She be Khaleesi of Eutherians
Did you know Mammals have more than 1 class
Prototherians lay eggs to hatch Metatherians have fanny packs
Eutherians have a belly button patch Volaticotherium had a membrane
From her fingers to her limbs to her tail base And that membrane made her like a sailplane First mammal in the game that could glide
away They say we started from the bottom
Now we’re here Mammals lived in fear
Until the dinos disappeared? Well…Repenomamus found with dinos in her
stomach Not only were they garnishes but they were
demolished! Move along, move along, move along
Dinos had your turn Now you’re birds,birds, birds Chirp chirp
Mammals rule the Earth! Move along, move along, move along
Dinos had your turn Now you’re birds, birds, birds Chirp chirp
Mammals rule the Earth! Travel forward to Ceno
Notice that Dinos have vanished That’s when mammals took advantage of the situation and exploded on the planet On the shortlist is Miohippus
That’s a horsey shorter than my hip is Count the toes, Hippus has three digits To Hyaenodon Hippus was delicious
But if speed was a killer then Hippus was vicious Predators needed that LA Fitness In nature if you can’t keep up with fast
food Then your whole species gets extinct’ed
Here’s a marsupial looking like a Saber Tooth Not a feline but closer to them dunkaroos
Thylacosmilus rocking that underbite Convergent Evolution – no copyrights
Did you know? Similar traits doesn’t mean they’re related
On the Tree of Life these Saber-Teeth are separated In some cases when it comes to evolution Different animals have the same solution
Have you ever bit into an avocado? Have you ever thought about that huge seed? Have you ever wondered what kind of animal could eat that seed and not bleed internally? Meet Megatherium
That’s the Ground Sloth Avocado’s evolutionary mate
Real friends Ate the avocados and spread the seeds as she defecates all over the place Hold up wait a minute have a case of mis-identity Not a Megatheriidae that’s a separate family
That’s there’s Paramylodon, family Mylodontidae Lived in North America no avocados on her
plate For the fertilizer-rers we have some larger
candidates Like Eremotherium our 3 ton heavy weight
Probably went through avocados Same way I do birthday cake
Like to have it all the time Because everyday’s my special day Introducing Gomphothere
Upper tusks, Elephant Lower tusks, Spatulas
Evolution was hella-bent! 10 feet tall at the shoulder
5 tons, bulldozer Vegetation, game over
She’s an Avocado soldier! Move along, move along, move along
Dinos had your turn Now you’re birds, birds, birds Chirp chirp
Mammals rule the Earth! Move along, move along, move along
Dinos had your turn Now you’re birds, birds, birds Chirp chirp
Mammals rule the Earth! Here we are in present day
OG mammals have paved the way Laid framework for mammalian traits
Like our inner ear, live birth, and huge brains One species is most savage
Has the power to affect the whole Planet Will we get our act together? Or will the Earth be ravaged? Real talk Thanks for watching Old School Mammals I hope you enjoyed this song
And consider subscribing to my channel It means a whole lot to me
I’d like to thank Google Making and Science For making this video possible
Check out their playlist for more awesome educational videos
I’d also like to thank the Museum of Natural and Cultural History at the University of
Oregon for providing the great location and specimens. Even if I got one of them wrong. But hey, like I said before: It’s okay to
make mistakes. I’ll see you next time!
