- Sixty-six million years ago, a giant asteroid struck the Earth. It wiped out 90% of all species, including all the large dinosaurs. How did life on Earth recover after this mass extinction? This video follows paleontologists working at a fossil site near Denver, Colorado. Their discoveries, along with discoveries from other sites, have allowed scientists to piece together how ecosystems recovered and changed in the aftermath of the asteroid.

I have, as part of my University class, had to answer quizzes based on these videos. Some of the least painful Uni work I've done in a while, I've actually really enjoyed this channel's content!
The Early Palaeocene is one of my favorite periods for this exact reason.
I've always been fascinated on how long it took plants and animals to recover and how Earth's landscape looked back then.
Please do more documentaries on the Palaeocene period!
For me too. Also the earliest Triassic is fascinating. I would also like to find a list, exhibition or documentary of most species so far known that survived these major extinctions, before they evolved into new things. Sort of the Creme de la Creme of the preceding age, that live in a changed world.
remarkable how much finer definition has been given to the explosion of Paleocene diversity, how quickly it took off. just an eye blink in the grand scheme, less than 1 million years
Man, you guys put out some great content. No melodrama or filler- just facts and good storytelling.
Those poor animals probably felt so scared when the asteroid struck and its aftermath. 😢
Soooo where did the one dislike come from?
Legumes makes a ton of sense. They still have a major role in feeding us today.
Probably religious people..
@@carlosmota2804 One dislike came from me for two reasons: 1. the loud ass music and 2. I want to see the rocks, etc. not the people. Ergo: 1 dislike.
Terrific documentary! This should be seen by more people.
such an underrated content. cursed youtube algorhithm
Very good video
Thanks
Fascinating stuff--Thank you for sharing such amazing results in an accessible format. There's only so much wonder a journal publication can convey.
You are so welcome!
They talk a million years like it's a fraction of time. It's an unbelievably long time
I was on the edge of my seat for this!
Ooh I always love voiceovers of the asteroid. Gives me chills. Educational and epic
I will never look at peas the same way again. Thanks.
You should do a video on the food chain collapses during the mass extinctions. You know, since animals can't live without food.
So, all of us can trace our lineage back to little shrews,right? Mind blowing!
this channel is so underrated
Thanks!
@@biointeractive do you like taeniolabis they are cute
I love this channel so much! You make such high quality content and on the most interesting topics. Wish I could upvote more than once.
very nice, underrated channel
Glad you think so!
I'm in uni for Marine Biology but man this is incredible, every discipline has their own incredible aspects.
congrats, Aeon!
The evidence is undeniable. Great documentary.
Thank you for this great video & the captioning. Much appreciate the accessibility.
very interesting to know about small animals in dinosaurs period . thanks for job
Glad you enjoyed it
Sometimes I'm looking at my cat resting beside of me and I'm thinking:
Here we are, two mammals. Some day, long long time ago we were one species.
When did our paths split?
When was the moment, when one of us went left, and the other one went right?
Was that in the final, 65 million years period, after the KT-event? Or was it before?
The most recent common ancestor between primates and cats probably was an ancestor of the magnorder Boreoeutheria and lived around 80 million years ago.
Wow, What a video!
Awesome
I am literally watching this because I can and because I like learning about animals.
And what about the European (French) Danian and Palaeocene (Paris Basin: Rilley la Montagne) fossils? Besides mammals, there are Paleocene non-marine molluscs with gigantism, e.g. in Physidae, Glandina, Oleacina, etc.
Ms Jenkins made me watch this -Success Academy scholar. Grade 6th.
Ms Santiago, also success academy scholar 6th grade
Without plants, how did small mammals survive initially after the blast?
No one speaks to this.
I guess the answer is that there must have been some plants.
Mushrooms, carcasses, surviving plants etc
@@thegameranch5935 Insects, many of which have wood drilling larva that would go nuts on all the death trees after the impact.
Great video uwu
How do I get to hangout with these guys? How amazing that must feel to discover an animal so ancient
you can get a job as amateur excavator pretty easily.
my brother used to assist in roman burial ground excavations. pretty sure its the same with paleontologists. because they want cheap or volunteering work force to do the hard work. its usually volunteers and students doing it. but some dig sites are pretty big so they want more people
you do the hard work of hauling rocks around and digging, archeologists or paleontologist will come with brushes afterwards and then you stay quiet to get near them, dont touch anything and listen to them
what was cool about almost 2000 year old skeletons on first glance from even an amatuer was that their teeth were pretty healthy, nice natural shape, and white.
shows how refined sugars are destroying our teeth in modern times
How many times has this been uploaded and under how many different names?
within 5-10 min, they found a bunch of fragile fossilized mammal bone that had just been sitting there on the surface for millions of years....uh okay
2:47: Meerkats, i believ. Like cats, dogs and bears, they ar members of the order Carnivora.
Excellent video,
Where mammals or proto mammals around long before the KT extinction event ?
mammals diverged around the same time as reptiles did from basal amniotes..
amniotes diverged into synapsids, diapsids and anapsids
synapsids into mammals, diapsids into reptiles, and anapsids into (debatably)turtles and bunch of other extinct animals... all around the same time
so yea, mammals were around long before kt extinction event. they just didnt manage to adapt fast enough to be competition to the dinosaurs.
which proved in the end to be a lucky advantage because mammals more easily survived the extinction event
because of being small and able to burrow
Interested. Of course "like". :)
Thanks!
It wiped out 75% of species not 90% that was the great dying of the Permian, your bottom description is wrong
Was the fern explosion made only of bush-like ferns or also by fern-trees?
I clicked on it thinking this is ashes of war from elden ring
11:26: a hyrax.

If darkness lasted years, how did any plant survive?
Seeds.
They can lie dormant for many years and then germinate.
So even when mature plants are gone, seeds will eventually sprout and regenerate the plant communities
Its also worth noting the continental states were almost ground zero as far as the asteroid was concerned, the vegetation recovery was probably quicker in other regions farther away, so chances are some broad leaf trees were already germinating soon after the initial impact winter in more secluded areas.
The same is true for mammals, btw, in Western NA only 4 to 6 species of mice-sized mammals survived the impact, and, as far as we know, they might not had been ancestral to any of the later Puercan North American mammals (unless Protoungulatum turns out to be a basal ungulate, but that's debatable), newer species sort of pop out in the fossil record, which likely means they were immigrants from Asia through Beringia or Europe through Greenland, with even some exchanges from South America being possible, unfortunately we have a very poor fossil record from that age in those places 😅
To try to tech this stuff without visually showing cladograms and explaining the morphology over time from clade to clade is almost pointless. It's more of a jumbled mess. Cladistics and monophyletic taxonomy is the easiest way to learn.

This really helped me understand how real God really is
The more I learned, the more I move away from God. All religious texts seem like work of fiction. I am atheist now! Thanks to Science!
@@yashas9974 Well, for me, God would be Nature itself, the workings of the Universe, and the unimaginably complex and precise mechanisms that run it. Organized religion is all manmade.
I'm happy to see that black people are finally taking their rightful place in science, after being kept out for so long.
Frustrating a scientist can't pronounce "species". Not "spee-shees".
It’s called palatalization. It’s really common in English. It’s also the reason why brigge became “bridge” and scip became “ship”.
Considering the word comes from the Latin ‘speciēs’, pronounced more like ‘spek-ee-ays’ (in the Classical pronunciation), it’s hard for us to judge what may be the ‘correct’ pronunciation in English!
‘Spee-sheez’ is the preferred variant in the UK. Elsewhere, it can vary.
Who says the narrator is a scientist?
Because of these difficulties, some leading theorists have abandoned the Miller-Urey experiment and the “primordial soup” theory it is claimed to support. In 2010, University College London biochemist Nick Lane stated the primordial soup theory “doesn’t hold water” and is “past its expiration date.” \fn{13 [13.] Deborah Kelley, “Is It Time To Throw Out ‘Primordial Soup’ Theory?,” NPR (February 7, 2010). } Instead, he proposes that life arose in undersea hydrothermal vents. But both the hydrothermal vent and primordial soup hypotheses face another major problem.
