Its Ironic that several of these theropod clade Species supressed tyrannosaurus on lenght; like it was hayday. Mega clade is quite underacknowledged to be really honest; it is good to see that is changing
I thought that only Spinosaurus is considered longer than Tyrannosaurus.
@@majster7072
Well, some predators were clearly longer than the average Tyrannosaurus rex, but few teropods out-long the biggest Tyrannosaurus rex, and only Spinosaurus aegyptiacus and may be Giganotosaurus and Carcharodontosaurus sauricius cach on and grow a liitle bit larger than Scotty.
Even though Tyrannosaurus rex clearly out weight every one of those (although Giganotosaurus carolinii coud posibly reach a weight that rivals with the Scotty)
@@majster7072 It is certainly far Longer; and likely more considerably taller. The lenght estimations were 15/15.6 -- 16m for Spinosaurus. Meanwhile the lenght was; at best; still 13.9 for Tyrannosaurus; mind to remind that there can be Spinosaurus specimens could be bigger than famous msnv specimen
@@battlechampion47 As far as I read; even scotty was barely 13.8m and the 14m was a severe overexaggrattion. So; quite a large number of Theropods could've supressed tyrannosaurus on lenght; and were likely taller than even the largest sprcimen; which the debate holds still between sue.
Such as Bahariasaurus; 13.5m; Saurophaganax; 13m; Giganatosaurus 14.4m; Charcharodontosaurus 13-14.2m; Oxalaia 13-14m; Tyranotitan 12-13m... I could list a dozen titanic theropods; even allosaurus estimated/speculated to grow 12m as of now; albeit uncertain; we can conclude in tallness and lenght; tyrannosaurus wasn't the titan. On weight; it ''probably'' could be; as you've to admit there's a *severe* drought/lack of Spinosaurus specimens (apart from the whole sigilmassasaurus ''debate'') as the famous msnv specimen might not even the 'largest' one; there' yet to be found.
This includes further research for the other forementioned theropods; as the tyrannosaurus is the most well-reseached one; as its fossils are on the ''safest'' area's for paleontologists.
@@battlechampion47 On the weight topic; tyranno is the 'fattest' and/or most outweight theropod; only as of now -- btw insert north america obese jokes/memes here(lol!); as I said the maximum for Tyrannosaurus is 8.9 to 9.2 tonnes; as far as I read; so further research to forementioned theropod species likely yield a far more; 'impressive' results; I am willing to bet. Even albeit Msnv Spinosaurinin has been 'decreased' in weight; it still yields 7.7tons; as 6 tons was an admitted underweight estimation; so; there could be further re-evaluation; however; as I said; it is still a lacking topic.
8:34 that timing there!
Excellent video as always!
It was not part of... what? What was it not part of?
Megaraptora is now considered part of non-tyrannosauroidea Coelurosauria. And Deltadromeus is now possibly a noasaur.
Wow was just looking through the channel
+Groque 16 I admire the video; done almost good; except the very outdated and underacknowledged Spinosaurus and Spinosauridae section
New studies show that Spinosaurus was not a very good swimmer and a study made in the same year as the “Spinosaurus walked on all fours theory” showed that it probably walked on two legs most of the time.
Newer and more accurate studies show that spinosaurus was a fish eater and walked on 2 medium-length legs.
Jake Grant yeah that’s exactly what the study said. Spinosaurus probably stood there and waited for fish to come by. Spinosaurus could still swim but not as well as the previous studies.
@@jakegrant7663 Actually; No. There's more evidence that *proven* the Spinosaurids were generalist predators; that consumed both terrestrial prey; amphibious crocodylimorphs and aquatic prey. There's validated evidence from three differentiated species of Spinosauridae; and two; İrritator and Siamosaurus were highly close relatives to the Spinosaurus.
I can provide source's -- if you'ld like
@@Man-ds9ir I have read the Handerson's studies; they are very conclusive and well documented; despite the occasional commentators; there has been no official answer to it; yet; it is valid.
The papper conducted that the Spinosaurus is capable of swimming; but exactly like other theropods; face upwards and limbs under; just like how an allosaurus would swim - if/when it has to... a position that would make water hunting absolutely *impossible* and rendering the theropod vulnerable to large (actuall) semi-aquatic crocodylimorph species.
Btw there's numerous fossil evidence/s that validates the Spinosaurid species did indeed hunted other animals; by logic people's belief of Spinosaurus somehow able to Subdue multiton-white shark sized fish; dragging it to land/killing it; but wouldn't be able to kill anything else *is* an oxymoron/paradox statement
Spinosaurus bipedal confirmed
Spinosaurus is no longer tought to be quadrupedal, that paper on which it was based on had a mistake in its data.
Still has short legs tho
Some believe that the aquatic sediments in the fossil came when the dinosaur died and that the carcass was washed during a flood. Carcharadontosaurus was also found similar with spinosaurus
@@user-fl8ng9np7v shorter; not short as the 2014 has been depicted.
Here; this is the fsac-kk specimen's ''actual'' frame. It is obvious that it is a smaller/subadult spinpsaur specimen; with clearly decent leg frame compared to its not mature body size :

This was/is the whole controversy.
The overexxgrated shortest legs have no basis
3:28 In Movie Series Jurassic Park lll & Jurassic World Camp Cretaceous Spinosaurus is a bigger than Tyrannosaurus Rex.
Person: (says spinosaurus was a quadruped on land)
Spinosaurus: 3:47
You: sees an artistic recreation of the species
You: believes that's exactly how it looked in life
😆
What the film on 12.05 , 4.05 and 2.29?
It is the best video
I think it's safer to say Spinosaurus wasn't a quodroped.
I think spinosaurus sail was most likely used for display because, if it was used for thermoregulation, why didn’t the other spinosaurs had the same sized sails?
+Veggieboy Ultimate Actually all spinosaurids've had enlarged vertebrea; spines. Althrough Spinosaurus was seriously evolved. (Btw this upload've made a huge mistake; Spinosaurus wasn't Quadrupedal; nor entirely aquatic)
The DORUK I remember reading an article that spinosaurus was a biped, but not being fully aquatic? Also I don’t think the other spinosaurs’ sails were large enough to thermoregulate, like all of them were only half or a third the size of spinosaurus sail.
@@veggieboyultimate The 2010 bio-isotope studies; they've concluded that the Spinosaurus itself shows results being same with the other Large Theropods; and among Spinosauridae clade there're massive differentiation's between habitat preference's.
(I suggest read the full papper; as the short paleonews sites present these news quite biased & exxegrated)
@@thedoruk6324 don't wanna sound like a doubter but you sure that paper isn't outdated? I have a thing when it comes to research papers, when they were published, and if its accuracy holds up.
@@veggieboyultimate I mean scotty ''research'' is pretty recent; I believe so
I feel bad cause alot of your videos are getting hit from COPPA, which is sad cause I really like your videos.
dinosaour world many many spiecies of dinosaour ever the modern day today no more but icant see the realy dinosour its unique spiecies ever guy
모든 공룡들의 똑같은 진화 파트 08: 수각류 - 메갈로사우루스류와 카르노사우루스류
Anthöny you really need to correct your video rigth now!
just yesterday Spino has another big change.
i like all spiecies skeleton dinosaour ever at all timers guys
This chanel is awesome but the guy behind it should really buy a microphone and stop with those pre-recorded voices.
+Pipo DuZob I *also* add that he/she should look for up-to-date information; not to use outdated & debunked fallacies
I respectfully agree.
Absolutely. When anything is pronounced "such a mimous", something's wrong...
I personally don't find it really annoying
But that would cost him shekels
Sigen insistiendo con el espinosaurus pescador y cuadrupedo. Poll sereno tiene un caramelo de cerebro.
wasn't concavenator hump-back product of a deformity (giantism)?
You forgot about Metriacanthosaurus. 😑
I think it's clear he isn't describing every single species that has ever lived
GOOD NEWS EVERYONE!
"Carnosauria" in its near original content (including Megalosauroidea and Spinosaurids) was restored thanks to a new basal carnosaur with the badass MadMax-ish name of Asfaltovenator (road hunter) found.
en.wikipedia.org/wiki/Carnosauria
en.wikipedia.org/wiki/Asfaltovenator
en.wiktionary.org/wiki/asfalto#Etymology_1
yo isnt fukuivenator a dromaeosaur????
you might have got it right first Spinosaurus, maybe the new version could be a sub-species as if it took different paths one for land and one for sea.
Holy shit, 40m/seconds, giganotosaurus was fast as fuck boi
11:10 giant southern Lizard not austral lizard 😂
Spinosaurus is NOT a quadruped, in fact, it could even run bipedally.
10:05 But, This is Giganotosaurus.
That's probably a Mapusaurus Giganotosaurus didnot lived with Argentinosaurus
Doraemon Universe I am saying that’s the clip from Chased by Dinosaurs. It was pronounced as Giganotosaurus. Before I heard anything about a Mapusaurus later on. Especially another Documentary or 2 like Planet Dinosaur. Not to mention that Wonderbook Video Game.
We sure bout this?
Why can’t dinosaurs be alive today so we can hunt them into extinction ourselves like we do with every other beautiful animal 😥
They are alive and well.
2:40 what it's su -cho -mimus
!!!!!
Nice video although Megaraptor was either a basal Coelurosaur or a basal Tyrannosaur.
I would hold off on that classification. Megaraptora has a mix of traits that makes it hard to identify. I don't understand why people put megaraptora in coelurosaur/tyrannosauroid branch when megaraptorans hand anatomy doesn't match theirs. I also find it hard to believe that they are basal to coelurosaurs or tyrannosauroid branch when there are no Jurassic megaraptorans to back that statement. I think they may be related to a basal tetanuran outside coelurosauria but I don't know and who really knows. I think people should believe what they want to believe.
Denzel Rogers Well the truth is the reason why we are saying that is because we actually found juvenile Megaraptors and they had similar skulls to juvenile Tyrannosaurs like juvenile T.rex.
@@denistyrant The skull is poorly fragmentary and we really don't know if it truly looked like that. Again we should wait until we have further evidence before making any judgments. Still, my point still stands, you still have to explain why their hand anatomy does not match those of tyrannosauroids. A prime example of this would be noasaurids which also have coelurosaur like adaptions but are completely in a different theropod family. Heck, even some members of megaraptora are thought to be noasaurids. I think a lot of paleontologist jump the gun to fast before they have conclusive evidence like they said t-rex having feathers when in actuality they didn't. But that's just my opinion.
@@denzelrogers6570 Thank you for the informative comments ! :)
Actually by now its a carnosaur relative of neovenatorians
please, anthony, do something else other than dinosaurs again
Last
I'd change the title from Megalosauroidea and Carnosauria to Megalosauroidea and Avetheropoda since the clade "Carnosauria" is no longer a valid term. Avetheropoda includes Allosauroidea and Coelosauria or however you spell the latter. It's late here lmao
Yes you're right, I've made many mistakes, I knew nothing about theropods classification before making this video and each paleontologists got its own classification!
@ Wait just realized you didn't include anything from Coelosauria in this video so "Megalosauroidea and Allosauroidea" is good enough. Learning is always good too. Your Megalosauroidea section of the video is great, though the section with Spinosaurus was a bit iffy. Everything else about this video came out well though. Keep up the good work.
It could be possible that megalsauroidea, allosauroidea, and megaraptora all make up carnosauria.
@@connorflaherty175 Carnosauria no longer exists
@@IsoSobek proof
Such a mimous! And no, there's not an unlimited number of pronouncing a language, even if it's dead, and even if you're American. Other than that, another interesting video.
Concave nator is another example. It really bugs me.
@@needfoolthings the *entirety* of spinosaurus was plain wrong tbh
He's not American though, he uses pre-recorded voice because as he once stated "wants to hide his terrible accent". So that's just a matter of shyness.
