Everybody’s saying it.
Best KDR in history folks
I thought it made birds with one stone
In case anyone genuinely has this misconception: birds branched off from the other dinosaurs during the Jurassic, probably over 100 million years before the astroid hit. Dinos didn’t suddenly grow feathers and a beak because a big rock hit them.

Now my head cannon is that’s exactly what happened.
I did not know this.
Interesting! Have we identified the last common ancestor of all modern birds yet? Or at least an estimate of when it would have lived?
It seems quite a few modern birds (Aves) lineages survived the K-Pg extinction (at least 5, last I checked), but when exactly they diversified is apparently still a contentious issue. The common ancestor almost definitely lived sometime during the cretaceous, so not THAT long ago in the grand scheme of things, but it definitely lived either before or during T-rex’s reign.
I was referring to Avialae, which is the clade defined as all dinosaurs more closely related to budgies than to deinonychus. Many of them would have seemed quite birdy to us, but like the other dinosaurs not many of them made it to the current day and the ones that did are all Aves.

Cool! Do we know how modern birds relate to these 5 lineages? (i.e. which branch became sparrows, ducks, ostriches, etc.?)
Can it properly be said to be one stone once it got through the atmosphere?
I doubt the atmosphere had much chance to break it up much since it was 10-15 km wide. Not like the little Chelyabinsk.
Of course, it’s like my f+#-: kidney stone. If it was just a bunch of chunks from the start I wouldn’t have pissed blood.
eh, seems like a technicality that you could reasonably argue either way
Aka perfect fodder for wasting time on Lemmy.
