Hey i want to learn more about prehistoric mammals. Specifically

>>2030147
walking with prehistoric beasts but a lot of smaller details are incorrect or new evidence has invalidated it like for example Gastornis was most likely a herbivore rather a then carnivore

there isn't much on them because they're extremely boring.

>>2030147
bugguy's right.
the public doesn't have much interest in Cenozoic mammals, so there isn't much out there in the form of videos aimed at adults.

Scientists are the opposite, they're way more interested in mammals than in dinosaurs and other prehistoric animals. There's probably 20 times more scientific articles on extinct mammals than there are on any other group of animals.

It doesn't get much more boring than reading scientific papers though. It's like drowning slowly in lukewarm vanilla pudding while listening to news about british golfing tournaments.

Question: are large birds like in OPs pic regarded as theropods?

our ancestors were pretty much just a bunch of retarded rats and guinea pigs.

no one wants to see that.

>>2030923
yes, all birds are theropods.

>>2030252
What is that based on? I'm genuinely interested.

Because when I look at a large bird like that with a large sharp beak, I'm thinking hunter right off the bat. Might just be some retarded shit like when scientists were saying that T. Rex might have been a scavenger. Give me a break.

Nice analogy
Made me laugh

thats not how it works.

>>2030929
looks like the most compelling evidence is from c12/c13 isotope studies of bone. Because certain carbon isotopes accumulate in meat but aren't common in plants we can tell what an animal ate by counting the isotopes ratio in their bones.

I like the dinosaur tail coming out of his ass.

Why did big predatory birds lose out to other land dwelling predators like wolves, cats and bears?

>>2030925
I think synapsids are pretty neat

>>2031005
they just got phased out slowly environmental stress probably put the nail in the coffin for them with Titanis being the last one in the early Plesitocene but hey the terror birds did do a lot better then the Sebecosuchids and Sparassodonts

I'm not convinced it was 100% herbivorous. I can believe it mostly but even ostriches and cassowaries eat meat. Most cranes too. Hell I even bet moas wouldn't pass up on something small they could catch.

>I'm not convinced it was 100% herbivorous.
nothing is 100% herbivorous
that isn't a requirement for being an herbivore

>>2030925
Cynognathus has that "i'm gonna fuck someone up" look.

>>2030147
There's actually quite a few documentaries out there on prehistoric mammals, albeit they're often on the same species :/ You can find a lot of them on YouTube like the Extinct (2001) TV series, Prehistoric Predators (2007), What Killed The Mega Beasts? (2002) and Monsters We Met (2004).

>>2030934
Yeah bro because cassowaries have large round beaks the size of your thick skull.

>>2032482
you may not like his example but he's absolutely right.

Gastornis was long thought to be a predator based on the beak. But molecular evidence killed that interpretation. When someone's guess based on morphology disagrees with solid molecular evidence, the guess loses.

>>2031700
Its diet probably consisted mainly of plant materal (Fruits, nuts, seeds, other such material) but i doubt it would have passed up the odd insect or grub, or carrion for that matter.

For example, Dromornis stirtoni from Australia was thought to be a large carnovorious hunter, but is now thought to be a slower moving herbovore or omnivore, with a strong hardy beak used for crushing hard fruits or nuts.
But i doubt it would have turned its beak up at carrion or other foods like it.

Excuse my horrid spelling

>>2030929
well phorusrhacids were carnivorous and so were the dromornithids
