Something that blew my mind, birds with teeth used to be common.

Probably angiosperms iykyk. Mammals replaced dinosaur niches in many cases but idk if that’s “rebuilding”, ig it depends on wym by that. You can say birds rebuilt a lot too (via pollination, migration, seed proliferation, predation etc)

I don't think that our opinion matters much in this case. The thing is, we do know which group of animals took the opportunity, went through adaptive radiation and became dominant life form in their ecological niche, respectively-birds practicaly have no competition in air, mammals are dominant in terrestrial ecosystems and flowering plants are dominant among primary producers on land, although in the last case their domination, due to specific adaptations, started earlier than late Cretaceous extinction. It's a matter of history rather than biology-we may argue about specific mechanisms of extinction and why certain groups of organisms survived while others did not, but there is no space for speculation who took over-on land, mammals inherited the planet. So, it's not so much about bad genes, it's about bad luck. Recent scientific study clearly shows that, if the asteroid had not collided with our planet, non-avian dinosaurs would still have been around. They were not on the brink of extinction at the time of impact, they were in fact thriving and diversifying. Who knows, given enough time, had they survived they could have even evolved high intelligence, much like mammals did during their adaptive radiation.

As far as I am aware, the dinosaurs didn't have any buildings, nor was their passing a catastrophe for the planet to recover from. Life simply goes on, or it doesn't.

Initially, if you look at fossils' evidences, some types of reptiles tried to expand their dimensions, look at the Titanoboa, but then, luckily, our climate started to change, and mammals became more favourite, being more versatile than reptiles or big birds.

Plants obviously had the advantage, or we wouldn't have plants. Plants not only thrived but also used mammmals and birds to fertilize, spread farther, and diversify better than the others, despite their lack of locomotion.

I have to say plants because without plants, there is no oxygen. Without oxygen, there is no animal life.

Says after the dinosaur extinction but then has birds on the list. Birds are dinosaurs lol.

Birds fly from point A to point B with seeds that drop in different directions priming the environment so that vegetation thrives. Mammals took advantage of this as part of their survival strategy. Without birds dropping seeds mammals would not survive.

Could it be that instead of one single event causing the extinction of dinosaurs, there were several events over the course of a few million years? Like it wasn't just the meteor, it was a prior change in the ecosystem and climate. The meteor and seismic activity were just an unlucky series of cataclysms. Or perhaps there was a bigger more haunting cause, our solar system could have been passing through an stellar phenomenon.

After the dinosaur extinction, who do you think had the biggest advantage in rebuilding Earth’s ecosystems?
