When will Emilia get her own Cardboard cutout?
Nah, she should get a puppet
@@lamecasuelas2 Mysogenist much?
Gafrers, I think she's good as is.
@@HLBear Not saying she is bad. Just saying that she is the only one not being "cardboarded" Yet. I love all 3 Presenters
Wait Ive never seen cardboard Ben
The recent trend of AI paleoart is really disconcerting. Important to remind people that paleoartists are valuable to science.
It'll never catch on as long as they are riddling with inaccuracies. You can't get away with AI Paleoart when scientific detail is currently so important.
The problem with using ai to produce products based on previous ones is we are hampering our innovation. Its literally a lazy device to stop us from needing to come up with any ideas. Its silly, just another step on the ladder to dumbing down the average person
@@infra_GrayFor now, AI paleoart can be inaccurate and problematic in how it gets simple details wrong that could change our view of a species.
@@infra_Gray contempt for artists is so weird, how jealous are you of others' talents lol
AI created images are no 'art' if you ask me, it's a threat and insult towards artists.
Love describing an ancient creature as ‘an absolute unit’. Brilliant!
Very Madonna 1990's
I love Mark Witton's art, particular his pterasaur stuff. It's pretty hard to beat having a leading pterasaur researcher depicting the animals for accuracy. Especially as they're not really the most conventional of critters.
Nice to see Emilia getting better and more confident at pronouncing weird latin prehistoric animal names. Keep it up!
7 DOS makes learning fun.
Emilia is fun! And I can't wait for them to find a mammal within the hundred pound range that lived during the mesozoic!
Emilia is such a fun presenter - everyone is great and she’s a lovely addition to the group!
i love that Julia d’Oleveira is like the de facto pterosaur artist. she just depicts them so beautifully
7 days of fun!
I personally found once fragmentary jaw of Alienagnathus in Ostrówka quarry and it's absolutelly fantastic to see this fish being redescribed
As someone who LOVES marine fossil, and adores the oddity type of fossilized life. Today is an amazing day ❤ lovely work y'all!!!
I love Emilia so much. She is adorable.
Mewing fish (I'm sorry)
Perhaps it used the extended jaw to stir the seabed in search of benthic prey?
Lol
or its a reverse swordfish
@@harrywoodman2988 Wouldn't the opposite be a shieldfish?
It could have had a lot of nerves in it and served to sense the electrical signals from the prey.
This fish Fr think he a mewing grimace shake Ohio at 3 AM Skibidi looksmaxxing sigma rizzler with level 5 gyatt speed in KFC sussy baka amogus fanum tax Pizza tower with Mr Beast Burger who buckles my shoes 😂
He's just a swordfish with the sword on the mandible instead of the cranium (probably the wrong terms for ancient fish, but hopefully you get what I mean)
I wonder what else is waiting to be found in the Chorrillo Formation. we got Maip in 2022, Patagorhynchus in 2023, and now Patagomaia in 2024 so what's next.
Emilia we all love you ❤
Thank you for leaving in natural pauses! So many educational videos sound like a run on sentence and you have no time to swallow the information you were just given. 🎉🎉
Didn't know there was Cretaceous Stegosaurs
It’s not necessarily the dams that have stopped the Chinook salmon. It’s the poor stewardship of the hatchery and how they have been releasing fewer and fewer salmon as the years have gone by this all could be fixed if they managed hatchery correctly. Furthermore, only the grand Cooley dam blocks salmon from going upstream..
Thanks for sharing, I always tell people that they did not have to do the Albini Falls Dam.
So cool for Homo Sapiens and Neanderthals to have coexisted.
We've known that Homo sapiens and Homo neanderthalensis had coexisted for a long time.
They did more than coexist. 😉
You mean : " humped"
@@EvilTwinRC51unfortunately
@@AmonTheWitchunfortonatly? I have some of those Genes, and i feel great.
On the stegosaurus: Did they find the thagomizer part of the new guy. I suspect that the evolution of that part along with the spikes along the back went all over the place over time. They would have had an impact on recognition for mating as well as on what they swung it at.
06:41 Hah! As a New Zealander and ex-Gondwanian, I was getting all patriotic to hear of a Gandwanian origin for modern mammals. Then I remembered that ackshually we have no history of any mammals (except the bats, but they flew here and don't count).
Your Aussie neighbour here, got the same feels and managed to keep them since we do have all the odd mammals and monotremes 😘
This creature literally predicted the chinspike fish things in my speculative biology
Now that is what i call a fish!
Omg! This is so fascinating
Paleontology has never been more beautiful!❤
A cretaceous stegosaur. Very cool. So the tyrannosaur vs. stegosaur fight in Fantasia could have been accurate after all.
No. Tyrannosaurus lived at the end of the cretaceous while this stegosaur lived during the early cretaceous.
@@theangrysuchomimus5163 Ok. Thanks.
And t-rex lived many tens of millions of years after the last Stegosaurus stegosaur died out.
Emelia is the answer to your question, "Why are we getting so many more subscriptions to the site all of a sudden?"😀
I love it when you host
Emilia is so great
Stay strong guys
11:52-12:05 Jean M Auel: CALLED IT
I was going to say the same thing.
I love seven days. This channel rules.
Great 7DOS, super well pesented by You, Emilia!
Always amazing quality of explaining even complicated astrophysics topics here!
And Emilia, in the "fun part" the first try of pronouncing "Ranis" with long aaaa, short i, no "ei" was very correct, followed by an "englification" anticorrection😉
Hi Emilia - do not let confuse you! The small town in Thuringia is pronounced "Rah - Niss" wit a long a. You are completely right. Thank you for all the detailed information 👍
I hope the orca calf is okay.
Bonus points for pronouncing Chinook correctly.
Thanks, Emilia
Good show.
Just going to put a fishing rant, here... The two biggest risk factors for salmon are overfishing by offshore vessels and pollution. Dams are way... way down the list and have been so since the 1990's. You might think the salmon don't make it to spawning grounds because of the huge concrete barrier, but that isn't true in the US at least. During spawning dams use fish ladders, which are a brilliant engineering strategy that allows salmon to go up the river without encountering the barrier of the dam or life-threatening spillway. The biggest issues are that the populations aren't capable of growing fast enough to counteract overfishing. I don't mean your uncle Sam and his buddy James with fishing poles. There's nothing wrong with catching a few salmon like that for the dinner table. No, I mean the international commercial fishing boats that line the estuaries with nets that catch salmon by the millions. We have our own laws against overfishing, but that doesn't stop boats from countries like Japan and Russia from camping out at the ends of our rivers. Not everybody can be trusted to be environmentally responsible and ethical when it comes to other nation's environmental resources.
Can we do an episode that touches on the evolution of transitory freshwater/saltwater migration and glacial melt?
Wow. Ben is prettier than ever! ❤
She got your viewership skyrocketing
Cool cohost. Fun science news. Love it!
This is savage. Science gang!
Ahhhh ... Emilia returns!!
Reminds me of an old Bill Engval joke about a fish with an under bite that got caught by a hook holding a cheeto.
It was a corndog!
@@vespurrs You're right! And what's a cornsog doing out here in the ocean? But you know me, I loooooove corndogs.
Love you guys! Keep up the great work ❤
Great presentation! Absolute unit had me rolling!!!
9:57 Let's start a band and call it ...!
Love you guys, keep up the great work
Beautiful diction! Thanks for sharing!
Can someone pass on a message to Ben's mum that I sent her new video to a friend to play for his 5 year old daughter and she was absolutely transfixed to the phone for the whole thing! Her dad said it was miraculous XD. Please release the next episodes soon!
Love your channel!
Just a note on Spanish. Two l's, as in Chorillo, are pronounced like a "y"
Emilia is excellent and lovely. I enjoy getting my science news from her.
I really think we should divide the Cretaceous into 3 different time zones. Having to say early late Cretaceous to mean something that lived in the Aptian or Cenomanian, well that's the middle point of the Cretaceous both chronologically, and as a distinct fauna stage isn't it? As the late early Cretaceous holds more similarities to this time than the early early Cretaceous.
Man Cretaceous South America was such an interesting place that fact that you had many non dinosaurian animals like mamals and land crocs rise to such (relatively speaking) high positions ecologically is very fascinating. It’s honestly a shame that even if the asteroid hadn’t hit this arrangement probably wouldn’t have lasted.
Loved the Gondwana bit - just read a book about Gondwana and it was really interesting.
I don’t know how I haven’t subscribed yet but I just did
Wow, Patagomaia was as big as the average modern coyote!
A well done report. 👍
6:55 Ohhhh my!
Wow, a halfbeak-like placoderm, the biggest mesozoic mammal ever found , a cretaceous stegosaur and a new scottish pterosaur!? This sure was a great week for paleontology (also the fact that the biggest mesozoic mammal was found in South America makes me really happy as I'm a south american myself!😁).Also I loved the video🦴🦕
I have a question:when i look at species with least concern categories's articles on Wikipedia their Pages are much smaller than species with much greater threat of extinction why is that?: ALL species must be Studied even though some are not threatened with extinction! so why like big animals are much more Studied than smaller Animals?
Enjoyable, informative, and generally quite well produced. I was particularly fascinated by the alien fish. We get lots of dinosaurs but little from that age. The The apparent demise of J60 was a sad note.
After getting into the military interest I lost my interest in Palaeontology for a bit, luckily I'm back, and have both interests and study them interchangeably.
It would be something like: "Rah-Ness" (the town in D) - but thanks for trying in such an entertaining way...
Beavis fish. Ace!
She's great!
My complements. Some of those names are a real mouthful.
You’re looking gorgeous these days, Ben! You’re simply GLOWING!
3:26 We absolutely need more salmon ladders. I would prefer a more natural looking side stream for the salmon but definitely salmon ladders at the very least. Hydro is definitely the cleanest renewable energy source. Lightyears over solar or wind.
Great stuff thanks.
Nealy as good as Emelia's dress, even!
I love the way she givesher personal touches to her presentations. That being said, presumely "Soutern" Orcas live south of the Equator. So if it is Salmon that are keeping these Orcas from starvation, then it is an invasive species that is keeping the Orcas alive. Salmon did not exist south of the Equator until man introduce them and trout there.
No these are near Vancouver, so pacific north west of the usa.
I could listen to you speak all day. I’m in love.
Hello @BenGThomas I have a video request: A common theme is that many dinosaurs were hunting in packs and showed some form of cooperation like many mammals do. However, I am not aware of any birds or reptiles living today that are really cooperating and hunting in groups. So where does this assumption come from. Why should modern reptiles have lost that ability? To me that is very unlikely...please explain :)
You should probably tell everyone where the Orca Pods actually are. In this case they are off Vancouver Island and Puget Sound in the Pacific North West of North America….ie around Vancouver/ Victoria and Seattle
Unrelated, but that is a very cute blouse.
That beaked fossil fish looks very similar to the beaked flying fishes though I am sure size and weight preclude a similar lifestyle
absolute unit
Concerning the Southern resident orcas; the dams on the Klamath River should be gone by this summer; the 4th and last was just breached. This should help save the salmon run that the Southern resident orcas and Native American tribes depend on.
Mercy!
Nice
Sounds like y'all got over that cold ha
the most interesting thing about southern resident orcas is that they are perfectly capable of eating other things, yet seem to accept starvation instead of just eating other fish. it's a case of culture dominating nature, creating a superceding layer of meaning that directs actions in a way that could become unsync'd to reality. reminds us of the power of human social culture/ideological behavior that can sometimes become desync'd with reality as well. so the irrationality of their cultural practice and the possibility of this irrationality is the most interesting thing.
Ranis would probably be pronounced Rahnis. Never heard of it, but that's the usual pronunciation.
And for Ilsenhöhle you could probably also just say Ilsen cave.
ABSOLUTE UNIT
It would seem like animals as smart as orcas would pack up and move elsewhere when rhe food runs out.
It's a big ocean, there's nothing to stop them from leaving.
Reverse Swordfish or Reverse Sawfish?
I love when someone uses the word fishes correctly, it feels so wrong
Dragon lady❤
MEWING FEESH
Cool
What was the Alienacanthus fish armoured against?
Life
@@michaellewellyn9080 That clearly worked well - they've been extinct for nearly 300 million years!
Crazy stuff like Dunkleosteus... who was also armored!
Swordfish but he's holding the blade underhanded
How did early homo sapiens live in cold weather? Did they already wear animal fur on their body?
Bro when did you transition gfy
love it

Ben, the lipstick looks great. Totally transforms you.
Very interesting video, especially the Mesozoic discoveries...and the narrator is utterly adorable......just sayin'.
