At about 2:59 a demon breaks through and the narration is garbled.
Huh. Seems like some audio bug that didn't appear in editing. Might reupload the video later. Thanks for pointing it out!
Edit: That portion has now been edited out of the video. If anyone wonders what we're talking about, their used to be a section where the audio got really weird-sounding and you couldn't hear my voice. If anyone was wondering what I was said during that part, I said "However in later species like Shuvuuia it's incredibly striking and strange".
Clasping on while mating ???
Since males and females both possessive could this shed light on the gay dinosaurs….????I’m sure there is a Gov neo-lib org out there willing to grant u $ to study this in depth for 10 years using tax payers $…..doink
Cool video.
@@remodesu Funny comment 'til you got political.
Ahh thanks for the explanation!
I listened and didn't hear anything wrong, hehe. 😁
Mononykus is exploding in popularity now that Prehistoric Planet portrayed it as fluffy and adorable. It deserves this.
My favorite dinosaurs. If they never went extinct, maybe they would become a variation of birds that were entirely flightless. Maybe they would replace all the flightless birds!
A-attractive?
@@viktordickinson7844 I'm sorry, I don't follow
@@ozzywalker609 i commented this on a totally different comment like a month ago. No idea why it's here too.
what if their arms were used for holding its body firmly onto something like a tree trunk? digging those claws in and using its upper body strength to stay latched on
This was my exact thought! Perhaps sleeping like that to keep a low profile, or hanging on to eat the bugs out of tree trunks or small rodent like animals or lizards from rock faces.
@@rainyrainold in my head i was thinking if its downy feathers were colored like quails or woodland birds, clinging the trunk of a tree could act as camouflage like a moth blending into a tree. Of course i have no idea if it looked like that so its pure speculation on my part.
these dinosaurs are weird but then I realized there's lemurs who mimick these type of weirdness, history repeats itself I guess
I never thought about this
@@DriftingStudent prehistoric squirrel
I COME FROM THE FUTURE WHERE MONONYKUS IS CONSIDERED ONE OF THE CUTEST ANIMALS OF ALL TIME
Could they be similar to woodpeckers though? Like using their arms to grab on to the trunk while they drill into it or chew into them? Or like how snakes invade burrows for food.
4:50 Clearly that finger is used for giving the bird.
Picturing one of these things using a termite mound as a punching bag before getting a treat is a sight to behold
One theory I thought you were going to mention but didn't I heard proposed about T-Rex. Another channel mentioned that it has been proposed that males might have used their arms for stabilizing during intercourse with mates as well as resting in a crouched position on the ground, ready to flee or ambush prey.
So nice to see different, less obvious and still weird infornative stuff.!.. Thanks !
I wonder if they used their claws for clinging on, or climbing, in a sense.
Maybe they were used to help them get up, and they were strong to have the strength to only push a short distance...
Idk, just a thought. I’m no professional, so I’m almost certainly wrong.
Don't sell yourself short..
All those so called professionals are just guessing themselves, so your guess is just as good as theirs
Perhaps it used those muscles to grab onto tree branches in a scissor motion to escape predators or to have a safe place to sleep hangin downwards like a sloth
4:47 tbf woodpecker tongues wrapping around their skull don’t either, so it is a possibility
I knew about these before this video. I'm glad that you have brought light to them.
I'm sharing your content to my friends.
A dinosaur with such a muscular finger could seriously give you the bird
0:00 I see them as the ultimate animals for everything listed and of course their more attractive features being primarily present in theropods and it’s just their overall design.
Feathers and scales as well.
Anyways, continue.
A-attractive?
Did I stutter.
@@viktordickinson7844 accurate deinonychus gf would be hot, so yes
@@wrightii5340 I’m a dilophosaurus simp but yes, deinonychus is among my top 10 dinosaurs that are the hottest… *snickers in semi-seriousness *
Fightless bird species have popped up a lot throughout evolutionary history but they tend to go extict.
Couldn't the arms have been used for mating? Maybe there was some mating ritual involving stimulating the female by holding her with those arms. Or they were just used to keep the female in place. Using them to break open mounds of insects or probe for them in treetrunks seems like an unlikely hypothesis to me, because the bodyshape would indicate a very awkward posture was needed to do that.
lmao maybe they ritually fingerblasted each other
Wow. Never knew. Mind blown.
Why the fuck does this music go so hard.
I want its name
0:03 omg this music, haven’t heard it in a long time
4:37 thank you, I was having a crappy day before I saw this
I love Mononychus, it was featured in Chased by Dinosaurs starring Nigel Marven
I love them.
Alvarezsaurus is my favorite dinosaur specifically, but the Alvarezsauridae are all so cool.
I think we have an exibit on insectivour dinosaurs in my museum in cape town south africa
Cool creatures
What is this song and why does it slap so hard
When the dino didnt skip the leg day but skip the arm day instead
Alvaresaurs where just really kinky dinos 🥲
4:49 "One alvarosauroid has a finger with quite alot of flexibility..."
Then proceeds to show a shadow of a girl lmao 😆
its for scale reference.
@@carlwheezerofsouls3273 r/whooosh
Tiny arms could be part of courtship and mating? Foreplay?
Correction, some still consider them Ornithomimasaurs, Sereno does at least
What is the song at the start
Mononykus is adorable though. Lil baby clawsies.
This feel like a hand version of vespersaurus: instead of having one strong toe, it has one strong finger.
Mayne their stubby limbs were for slithering or belly scooting, and for jumping back up when they transition back to bipedal locomotion.
It's hard to tell if this is a typo, or if you're a black guy proclomating his theory of what the arms were for. Either way it's funny.
@@evanseekins517 Not sure what you mean. "Mayne" was definitely a typo. Not sure why Autocorrect took the interpretation that it did. Yankees seem to think I talk like a black person for some reason. In the South, the dialects don't diverge as much.
He'll yea
So cute.
Yordan Alvarezsaurus?
These guys remind me of emus.
they look like jackles from Halo
Ahhh I see, ancestors of the girls of the Beautiful Finger Lakes !
I Think... These small wings/ arms 😅 were used for mating. These fingers are not exactly vestibular, the most obvious answer is usually the most simple.
Thank you for mentioning my dinosaur that has my last name in it
everyone in the comments saying they used their arm muscles to cling on to trees... how are they going to grab on with a single finger? smh
Do any animals alive today have strong single fingers?
@@Skyjengi just imagine it, how could you get leverage with a single finger
What if these animals were arboreal, or tree dwellers?
Short arms is a really bad adaptation to living in a tree.
Alvarasaurus, or as I call him nubsly.
Are they azorean?
it's Boban Filipović, not Bobon
i bet claws where for fighting
i had to rewatch this because i forgot what happened
it's just a prehistoric goose.
Ultimate animals?? Hunh?
Killing something that is slow but strongly armored? Turtles or ankylosaurs?
I feel like even the smallest, clubless, ankylosaurs would be able to kill an Alvarezsaur if it ever tried to press its body uo close and chip away at it with those close. They were slow but they weren’t defenseless.
I would guess egg eaters myself. 👍
Creaking Skull
i wonder if these guys were the real egg thiefs
(its kinda mad that nobody in the past took one look at these things and their environment and went 'Eggs everywhere, really strong short forelimbs with big claws open eggs... maybe they ate eggs' and were instead like 'Ah yes, an anteater' even though that gives absolutely 0 reason as to why their arms would be reduced as well as the large claw. Just saying)
yes but how would a large singular claw provide use in egg-eating? The claw had some kind of use, as alvarezsaur evolution shows increased robustness in the arms and a reduction of other claws for a singular claw. Short arms would be useless in egg-eating.
@@neildegrassetysonwithaknif7124 they would help crush the egg and would let them hold it close to the body. I'm not the one saying it, look it up
@@flightlesslord2688 I'm just saying, it would be quite difficult to pick up an egg when your arms are so short. You'd have to lay down on the ground, and at that point, might as well just use your mouth.
The scratch digging theory/insectivore theory sounds the best, since robust arms would be great for digging into large mounds. Also, if you didn't know, it's been found that alvarezsaurids like shuvuuia had large pupils (thus having a high probability of nocturnality) and could pick up high frequencies of sounds. However, there is still questions on what the latter would be used for. Just a new factoid. The paper was published I think last week or this week.
@@neildegrassetysonwithaknif7124 why the hell would the arms get smaller for that? It would just put the animal at risk of getting bit. The egg idea has actual fossil basis
@@flightlesslord2688 Termites don't bite.
dino doggos
True or false: Flying birds have longer wings/fins than fish do relative to their mass.
True.
Why? Because water is thicker.
What's with short-winged birds? Simple: They were FLYING in a much denser atmosphere.
After reading your dribble I forgot what channel I was watching for a minute, thought it was Scimandan and tinfoil Tuesday.
Lmao "thicker" jesus wept
No atmosphere wasn't denser...
yes i am a little short
Question for anyone: Are there any dinosaurs left that can't be easily placed in any major group? I would have said Psittacosaurus which is a bipedal ceratopsian, Baryonyx which has been shown to be a spinosaur, or Stygimoloch which is a pachycephalosaur. Maybe Tanystropheus?
*Pachycephalosaurus.
Tanystropheus wasn't a dinosaur, so hard to place it in a group with dinosaurs ;)
Herrerasaurus and Eoraptor are probably the best examples. Are they theropods? Are they sauropodomorphs? Are they none of the above? Nobody seems to be able to agree. Some recent analysis say they’re basal theropods. Other analysis have placed them as closer relatives to Plateosaurus. Others were unable to clearly place them in one group or the other. So their placement currently exists as a nebuluous question mark that can and probably will jump back and forth some more times before they ever find a true home.
I know about a very large variety of dinosaurs, but all by the wrong names because of fossil fighters
theyre raptors. end of story
Alvarez is a common last name in Spain.
So Alvarezsaurus is like Obamasaurus to an american.
I think its also somewhat common in latin america, Im chilean and thats my last name
The paleontologist discovered a lesbian dinosaur they gave it the scientific name of licalotopus
One thing. While the dinosaur is large, awesome and cool then these alone aren't enough to give it popularity. For example, if the dinosaur is from Europe or Africa then no one cares, but if the dinosaur is from the US then even the European media goes nuts because these US' dinosaurs are American.
Let's narow it down
-only one, very pointy, spike per arm
-only capable of close range stabing
-evolutionarily questionable (closer to a chicken than an actual predator)
They must be Londoners then.
Rightfully forgotten that’s the ugliest dinosaur name I ever heard
3:10 'Huge arm muscles..." ROFL! For what!? Flying, duh! Huge arm muscles! It certainly did not walk on those front limbs. Huge arm muscles never occur unless there is huge work being done by them. VERY basic biology.
Now tell those artists to get their pens our of the arses and draw that spinal column like the spinal column of bird, because THAT'S WHAT IT IS!
There are many ways to activate muscle growth aside from physical trauma, Very basic tour de france strategy.
@@Soshoyo Like what? Have you ever seen a body-builder or powerlifter who doesn't lift weights and work out?
And it isn't just muscles. The bones are thick! Even if the dinosaur was injecting steroids like you suggest (ROFL), that would not increase bone mass.
@@jameso1447 There are other ways for chemicals to appear inside animals other than injections, Have you never seen man who maintains a well built physique despite never training or man who fails to lose fat or build muscle after years of instructed training and strict diet?
@@Soshoyo That has absolutely nothing to do with BIG ARM BONES and big arm muscles. Why are you desperately clinging to a pathetically undefendible idea?
@@jameso1447 I'm not desperately clinging to any thing i'm simply stating biological facts, Muscle growth is caused by chemical reactions not labour, Stress is simply one method to force these chemical reactions to occur through injury, Enlarged muscles through training aren't big because they got stronger they are big because the muscle fibres were damaged and the incomplete regeneration causing excess biomass to form in the damaged tissue.
Muscle growth in wild animals are more genetic than a result of labour, Gorillas got big not because they do heavier work than chimpanzees, Gorillas got big because their social system revolved around the strongest male having exclusive rights to mating resulting in eventual muscle growth in the species while chimpanzees have a more advanced social structure akin to humans resulting in better genetic diversity in its' groups, Big cats in particular in the case of breeding become lazier as they get bigger due to relatively weaker hearts with the largest big cat breed being the most docile of its' kin and despite the lesser amount of physical labour they commit they still maintain their naturally large muscle mass far larger than other breeds.
I don't know why you show dinosaurs with a background of newspapers. That is so out of place, it makes the rest of the video lose all credibility.
He's on a budget lol
I like the aesthetic. Why would the aesthetic presentation ruin the credibility?
