I’m really glad that you described in full detail the effects of the asteroid impact at the end of the Cretaceous, instead of vaguely stating “most life and all non-avian dinosaurs died, but now there are mammals”. Great video!

Isn’t it true that many small dinosaurs survived this mass extinction? And they are the ancestors of today’s birds? I’m probably misunderstanding something.

The birds had already started their evolution in the Jurassic period and, by the time the asteroid hit at the end of the Cretaceous, had already more than 90 million years of evolution unter their belt. At that point they were already pretty close to today's birds in morphology. So, while belonging to the dinosaurs, birds had already fully branched off and come to their own when the main dinosaur lineages where wiped out. In light of that, stating that all dinosaurs got wiped out isn't entirely wrong. Though the better wording would be that all non-avian dinosaurs went extinct. BTW, despite the name and similar reptilian origin, Pterosaurs and Ichtiosaurs were not actually dinosaurs but entirely different lineages. And I think it's the same with Plesiosaurs.

These avian dinosaurs were already birds as we know them! Only a few lineages survived and they form the diversity of birds we know today. It’s possible a few toothed birds survived but they clearly died out in the early paleogene.

Again I gotta correct u but I won't make it long like the last video. Not all dinosaurs died from the meteor, birds r theropod dinosaurs n the only group of them to survive cuz they were smaller than most dinosaurs but also able to fly long distances I search of food n somehow they also had an edge on the smaller pterosaurs tha remained by the end of the cretaceous period allowing the birds to outcompete them into extinction

a Question i have: is it true that Chickens and blackbirds evolved from T-Rexes?

No ambiguity in the name, "THE GREAT DYING." Can't help but to add some bass when I say that name.

Professor Dave, how come you failed to mention the DeclanTraps and that monumental eruption’s impact on the dinosaur environment before the meteor strike? There has not been a mass extinction that did not involve volcanism. At 66 MYA is no different. I

Жыл бұрын

It wasn't the worst though. Worst extinctions happen when there are long-term effects affecting the atmosphere, like great oxygenation event or mantle spewing lava and CO2 continuously for millions of years. While Chicxulub most definitely did kill off majority of large land life it is now more predominantly thought that it was the Deccan Traps was already playing a role toward saturating oceans and atmosphere with CO2, also becoming more active around that time (unknown if by consequence from this or some other impact, but seems unlikely). Keep in mind that while Chicxulub was the largest crater of that time we've found it's also very likely it wasn't the only one either.

It was the last of multiple global extinction events, each of which exerted pressure on surviving life to be less susceptible to THAT sort of event’s aftermath. Basically, life is getting tougher and more adaptable. The Big One was The Great Dying, associated with the Siberian Traps tectonic event.

Repeating my pseudo-poetic comment from the last episode... It's oddly beautiful that the largest mass extinction was the precursor to the era of giants, the era of dinosaurs.
