#there's other misunderstandings in here on human evolution but I'm not an anthropologist so I'm not touching that

[a-dinosaur-a-day]

... you have a lot of terrible misunderstandings about dinosaurs and the mass extinction

nonavian dinosaurs weren't lizards, at all. lizards are uniquely adapted reptiles that diverged from other reptiles about 260 million years ago. dinosaurs are in a completely separate group. dinosaurs are also in the group that can be roughly described as "birds and their relatives", because birds evolved from dinosaurs (and, thus, are living dinosaurs). most, if not all, dinosaurs were warm blooded, and were very cold resistant, and bird like. and oxygen has got nothing to do with it (in fact, the idea that more oxygen = bigger animals has been debunked pretty thoroughly multiple times).

like, you keep calling them lizards. I cannot stress enough how wrong that is. please stop dealing me psychic damage.

so the Spouse and I like to have a lot of verbal discussions about the universe where the asteroid didn't hit. mainly spec evo stuff. what would evolve into what, that kind of thing. we know we're not alone in that.

we maintain that humans evolved alongside some pretty terrifying mammalian megafauna, so why not dinosaurian? so what would a realistic sapient ape in a dinosaur world be?

it's taken some thinking, but:

wookies.

we'd be wookies.

no need to leave the trees, the grass would be very unsafe if it evolved the same

no need to leave the trees, we remain furry

we could build tree houses and other structures, in the trees, to stay out of the range of predators

that's. just wookies. that's just the wookies.
