So dinosaur hips lie?
OMG, I can´t stop laughing, so true! XD XP
Never thought of it, but convergent evolution in prehistoric animals really could make it difficult to classify dinosaurs to their respective "species".
Imagine having the skeletol remains of a *Shark, Dolphin, and Human* having no prior knowledge of mammalia, you'd be laughed at to suggest *dolphins are closer related to humans.*
Well, this problem is more akin to having the skeletons of various sharks, dophins, whales and large fish and comparing the shape of certain bones to try and classify them into groups. Not especially useful, but for dinosaurs its all we've got to try and organise them somehow.
I disagree. Human and dolphin skeletons have strongly analogous parts and bear more of a superficial resemblance to each other compared to a fish skeleton.
Blue Jim I agree with you .. look at the vertebrae of dolphins and compare them to a shark vertebrae and a human vertebrae, you'll be astonished to see the results !
Well, while I understand your intent, but it's going to be difficult to compare shark bones with them only having the jaws as real bones. The rest of their bodies are just cartilages.
Wan Sueanoi Yep they are mostly cartilaginous I know and that's what I meant by my point.
I was taking a dinosaur course this semester in college.... Haflway through, the classification changed completely.
That first one could seriously change our understanding of dinosaur evolution, it's pretty interesting.
So the question is: When will there be the first big movie showing dinosaurs with feathers?
Two steps in walking the dinosaurs: 1. Open the door. 2. Get on the floor.
*EVERYBODY DO THE DINOSAUR!*
The floor is lava
Kyouske Litz If you're talking about the K-PG mass extinction then yes, the floor is lava.
The lava is under the floor. Many miles down.
Can't wait to get into this field and study it at university in a few years time - with every piece of news and the more I learn the more fascinated I am. Thanks for the awesome video SciShow team!
Ha ha, I always found the reclassification of dinosaurs amusing.
"So, as it turns out, the kind of dinosaurs birds are actually are in the group of dinosaurs we call the 'bird-hipped' dinosaurs! Who would have thought?"
it is kinda funny, honestly
what's funnier is that they used to be lizard-hipped dinosaurs like? ah, yes, birds! my favourite lizard-hipped dinosaurs, love those boys
"Evolution is just a series of lucky breaks and adaptations."
Well said, Hank.
What about the unlucky ones?
Evolution is chaos characterized by two steps forward and one step back.
I enjoy hearing about dinosaurs and other prehistoric animals as well as our prehistoric ancestors. Very interesting.
Well our ancestors never lived in the same time period as dinosaurs if that is what you are inferring.
As well very interesting but then again I may have misinterpreted what message you were getting across
@@diegobrando3409No, they did
@@minimunchers8002 I'm going to assume you actually know homo neanderthalsis lived 1 million years ago and your just kidding when you imply that early man lived along side dinosaurs. Unless your going to refer the small mammals that dinosaurs ate being our ancestors, which will be funny but piss me off that I didn't think about that.
The way Hank was talking in this video, I started to really want to see actual dinosaurs develop from eggs, but then I realized that that wasn't possible.
you should have gone over that full baby bird/dinosaur whatever, that was found in amber recently
Brookie Cookie Jurassic Park plays loudly in back ground
Chances are this video was already finished before that was published.
scishow is hooked on dino discoveries eh?
Can't blame them if they are.
Tell Me This
Everybody is hooked on dinosaurs, it's something that we just can't stop wanting to know more about.
Dinosaurs are just cool, no two ways about it.
Ah, scishow and dinosaurs, my favourite mix :)
maybe it's hard to classify all the dinosaurs because you're looking at many millions of years and evolution is a gradual process
Not only a dinosaur tail, the same group of scientists recently published a paper describing a whole juvenile bird (avian dinosaur) trapped in amber from the same formation. I don't click on links in TH-cam comments, so I won't leave one, but if you want to look it up the article is called "A mid-Cretaceous enanthiornithine (Aves) hatchling preserved in Burmese amber with unusual plumage." The scientists are from China and Canada, and two of the more prominent authors are Lida Xing, from the China University of Geoscience, and Ryan O'Connell from the University of Regina. If anyone is interested, they have an unedited early stage manuscript online, and there are a couple of recent news articles about it with pictures of the birds feet in amber. Thought Id share because I only stumbled across this because I only stumbled across the article on accident and it is worth sharing!
"Evolution is just a series of lucky breaks." LOL.
"Popping the collar" of a shirt in urban Montana: Releasing that one button on the right side yet leaving the left one the way that you found it. Before you took out all the pins (and carefully disposing of them safely) after removing it from the cellophane, et cetera.
Love this it rally shows how dinosaurs evolved from what they where to what they are know it's cool
Thank you for subtitles
It's insane how far science has come. When I was a kid the idea of ever being able to identify the color of a dinosaur was science fiction! NOW......if a bird fossil is in good enough shape we can identify EXACTLY the color of ALL OF their feathers!!!! They have already identified the exact and different colors of many dinosaurs by very detailed fossils!! They are doing the thing NONE 0F US EVER BELEIVED could possibly be done as children!!! Science is such a beautiful thing!!!
Good watch. Thanks.
Would like to see you guys cover the very recent ( like 4 days ago) discovery of a 300.000 years old Homosapiens' skull in Morocco
Gotta catch em all
so...their hips DO lie
Fascinating, I love this stuff... I am one of those, who are still offended and angry for they still resist to portray dinasours with feathers
The Ramdom Channel Check out Saurian, a scientificaly accurate dinosaur game, in case you don't know about it yet
Panic Wolves THANKS!!
So, finally, a REASON why the avian theropods survived. Very, very cool.
But what you said about the advantage of quick hatching applies only to precocial hatchlings; the altricial hatchlings are going nowhere in case of an emergency. This would seem to imply that they came into existence only after the K-Pg event.
3:17 yeah i guess if you don't count Tuatara, witch has been around since the Triassic period. and still with us today
tuatara is not a dinosaur, so of course it isn't counted.
-heck im pretty sure its not even an archosaur-
please, could you manage even a quick Wikipedia search. let alone some real research.obviously the term dinosaur is subjective, that being said Tuatara is of the lepidosauria suborder witch is the sister taxon of the Archosaur sub class. look up the term if your confused. so back to the term dinosaur, the Tuatara is a lizard-like reptile. lizards are from the Lacertilia suborder. ok so Tuatara been around since the Triassic 200million years ago they are reptiles not lizards, and they are the sister taxon to the order witch in-compasses all birds crocs and turtles. witch are the decedents of dinosaurs.
27'seconds, when I try to catch a fly
Gotta catch 'em all! 😜
I LOVE HANK AND DINOSAURS
I love your profile pic
k8 Thank you
I hope we find an entire archaeopteryx fossilized in amber one day
It makes me sad to see the views going down on this channel. These guys were like the original all sources given science channel. :(
This video was on my birthday!
Thank you for not talking about the T-Rex scale imprints that were found which don't disprove the feathered T. Rex theory although every single unscientific "scientific" news sites claim it to do so.
That One Guy t rexes most likely had feathers. Maybe not everywhere, but they probably did. Their most direct descendant is the chicken and you know how many feathers they had
How do you get to dinosaur fossils trapped in rocks? Blow it up with a stick of dino-mite.
Master Therion Just no...
Master Therion You tried too hard. Keep it simple. "How do you find dinosaurs? Use dino-mite."
Master Therion Cause then you mite get ye skeleton. That's the joke right?
That's how you do it in Australia in the early nineties atleast.
annoying orange said that in a how2
Waao really astonishing facts
I hate it when I get randomly unsubscribed from these great channels
Thought you were going to mention the newly-found best preserved fossil of a nodosaur.
Yay Dinosaurs!!
I first pronounced it diplo-doe-cus, then switched to dip-LODO- cus, now Hank's saying dipLODercus. What do I tell when one is charging at me and my fellow time travelers?
Have you guys done a SciShow about Leonardo the dino?
lol Ken Ham believes this is the proof of the great flood
Whoa there, I've never heard someone say Diplodocus like that
dino news are the best
No mention of the incredibly preserved anky type dinosaur? Skin, horns all that good stuff.
DINOSAUR!!
Got find them ALL!!!!!!
Take that, Ken Ham!
my PUBIS faces up when i get excited
Um, excuse me, MUMMIFIED NODOSAUR.
If the worl is cold, making nests is a winner. Laying on the ground or burying and leave, not so good.
type in awesome on the screen.
can you guys do a video about places that humans haven't yet achieved to get into/study?
feathers for thermal management
I knew they were going to mention feathers
Yeah I'll assume a bunch of things that I really don't know for sure about dinosaurs and with that I'll affirm that evolution is pure random.
Very logic.
It's hardly purely random. Mutations themselves are as far as we can tell, but natural selection isn't.
Hey you are EONS host
so are dinosaurs so ripped because they've been lifting all those barbules? come on it was funny.
Getting up and running... I thought hank said "sh*ting up and running"
Why hasn't anyone talked about how we have multiple dinosaur red blood cells including those of Tyrannosaurus and how Japanese scientist discovered how to efficiently clone using somatic cells?
There also is that wicked artificial womb technology, and the fact that different Japanese scientist grew a baby chicken in a sealed paper towel holder...
I guess what I'm getting at, is, I want to see Jurassic Park.
I rather have trilobites back then dinosaurs
Caleb Reynolds
New headcanon: a tiny group of the non avian dinosaurs survived the extinction in biodomes, and are masterminding global warming to return the earth to a more suitable temperature
TheRedKnight we have the horseshoe crab, very similar.
spindash64 dinosaurs were fine at cooler temperatures, but they weren't fine with our currently lower oxygen amount. Dinosaurs were warm blooded after all
We dont have the cells, only the structure preserved in rock. Theres no actual organic matter for using
Can you do an episode on what ADHD is? I already know, I have it, it's just difficult for me to explain to other people.
hi! my uncle always said that ants don't eat honey but sugar. i would like you to do a video about why ants don't eat honey but sugar?
I'm kind of new in this channel so i don't know if you did it before
Katty Garcia I have found ants inside the honey pot more than once, so the claim seems not accurate. Maybe some species of ant prefer sugar to honey, but not the ones where I live. Also honey contains some part of sugar naturally.
There are ants that feed on nectar and sweet plant fluids. and store it to feed other members of the colony. They are called honey pot ants. Honey has glucose and fructose as well as other types of sugars. While their "honey" is not true honey it is from the same source as bee honey.
That's at least twice as long in the egg as an ostrich.
If the mass extinction event never happened, could these dinosaurs evolve to become intelligent? Would that keep them dominant on Earth and never give rise to us humans?
Open the door
Get on the floor
Everybody walk the Dinosaur
wish I had a lucky break I feel as old as a dinosaur
Did they try weighting the different characteristics differently?
I wish more people would watch this show. So many ignorant people out there.
Did anyone else think about that 'thigh bone' they found on mars when watched this?
I can't believe you didn't mention this fossil of a nodosaur with much more than just bones:
www.nationalgeographic.com/magazine/2017/06/dinosaur-nodosaur-fossil-discovery/
anyone else catch that pokemon pun, or was it just me. (0:27)
Avian therapods!!! They are yummy!!!!
Hips don't lie. ;-)
Dont believe the hips.
100 people don't like having their mind blown by dinosaur facts.
What about the arkasorous?
????????
Here is a question for you. Does honey lose it's nutrients if added to hot water?
If they could find exactly where that chunk of amber with dino tail stuck in it came from, they might find the rest of the dino. I hope someone's looking for it,,,
Steve Harris They are actually digging in the same place and already found other stuff. Last week they found an entire dino-bird inside the amber.
I was a dinosaur in a multiverse
90% of people who post a comment before this one haven't even watched the actual video
Sombrero Cucumber just look at the title and or the presenter and away we go...
wow you made a very expansive "first" comment
cool video, ehh yes
Mooshroom you are 1st
It WAS a good and cool video!
Guess I am :)
wanna test old ideas? lets do an honest look at the aquatic ape theory (by its defendants, not its haters, ok?)
Is it possible that we are living in a black hole right now? Would we know if we were because if we were inside we would be fine because we have oxygen and everything correct?
I was a fan...
But now I'm a 20,000 hp turbofan😃
you are FANtastic
Dvd Dvd That joke really BLEW me away....
We gotta keep commenting, this comment section is losing wind.
hi
how are ya
That settles it; dinos are pokemon
0:29
Pokemon
roflmao the Pokémon reference
But crocodiles' incubation period is ~80 days as well. Why didn't they die out then.
Crocodiles don't need too eat much. They could easily live two years without food.
What is in the way of making Jurassic park?
Sooooo, might I ask. When is our worlds mega-evolution? As in a sense of he's saying species & humanity have been lucky catastrophic breaks..are we slow evolving or are we..just waiting for something to happen?
Also looking at the age of the known Universe, it happened super fast! relatively talking :)
But anyway you're right, it taken at least 14 billion years to evolve.
I feel like these distinctions between dinosaur types will soon be called a social construct ...
For much of history, classification in animals was more bookkeeping than science, so you're not exactly joking. That's why cladistic analysis was invented to try to get away from that. Even that method is considered clunky by some.
Damien Stone People annoy me trying to assume my dinosaur's species when we walk in tye street. It's a mutt you morons, i found it in a shelter.
Pffft, listening to the DUP I now know dinosaurs never existed.
What Dinosaurs were actually Pokemons? Fcking Knew it
i wish scishow geology was a thing =/
so they classify dinos depending on what way their junk hangs?
Why do my lips burn when I eat spicy food?
Did sauropods possibly have feather?
from what i've read, they might've had a "mane" of feathers, and i've seen art of them with little "brushes" of feathers/quills near the end of the tails. they probably weren't completely covered in feathers though, since most of them were too big and would've overheated easily with that much insulation
-the hatchlings of some species mightve been really fuzzy though and that makes me happy-
thank you for your info
Thank you sci show, for continuing your long running tradition of NOT showing us photographs of the thing you are trying to tell us about!! Hell even a newspaper article would at least have a photo of the dino tail feathers preserved in amber, and here you are using a visual medium and thinking "Why would anyone want to see actual dinosaur feathers that have never been seen before? We'll just describe it and let everyone use their imaginations." smh
David Stagg Copyright limits I guess.
Copyright limits on a photograph of that dino tail feather? A quick google search shows hundreds of them, I don't see how this could be copyrighted.
What is the difference between green and purple grapes
Wunderr Kid That is an interesting one but would have to cover many other fruits with color variations (plums, apples, peers, citrics, melons...).
where do phobias come from?
