"We don't have as much of the tail as maybe we would want" 2020: "Allow me to introduce myself"

"we don't have as much of a tail as we would want" ah, the precious days of 2015, thinking that any part of Spinosaurus's body could possibly be normal.

How is this already outdated?!? I love spino, but it changes shape more often than an octopus.

6:45 "We don't have as much of the tail as maybe we would want" Laughs in 2020.

I can only imagine how the paleontologists who discovered these dinosaurs would react if they saw how their dinosaurs actually looked like.

Yesss! I've been waiting so long! I love all your videos

You should do a part 2 now that we have more info on the tail especially

'and i made myself sad, coz i'll never get to do that' 16:41

You should do "your dinosaurs are wrong was WRONG" episode for spinosaurus. I bet all of us would love to see it after all the news we got since this episode came out.

You should revisit the spino with the recent updates on the tail shape and all

It's absolutely insane how much our picture of Spinosaurus has changed recently. Might be more dramatic than any other dinosaur discovered so far

6:44 They found the tail, and it's an aquatic adaptation! Just a few weeks ago, a study was released about a new, more complete Spinosaurus fossil they just found. The neural spines on the caudal vertebrae (the bit that sticks upward out of the tail bones) are really tall, so we now think it had a finned, eel-like tail that it used for swimming. kzfaq.info/get/bejne/nKqYosl-nZe2gXk.html

This year spinosaurus got EVEN weirder. As if it could.

2020: no, thats wrong tail

I always looked at Spinosaurus and I always said "He must be a great swimmer."

And then came 2021, and Spinosaurus is a fierce stork (minus the flying and the babies)

The new spinosaurus is like a pelican, crocodile, dinosaur hybrid And I love it

Spino is my favourite dinosaur because he always finds a way to get even weirder to confuse scientists, in just 6 years he's yet again completely different

I'm just waiting for the follow-up episode describing the new gigantic paddle tail

‘We don’t have as much of the tail as maybe we would want’ Honestly the discovery of the fin like tail has made me so happy, the more we can learn about dinosaurs the better!!!

the shape of the sail probably varied in bone structure, meaning each sail of an individual spinosaur was different.

PLEASE do a Spino update!

'Other dinosaurs are too scared to be as weird as spinosaurus' *Deinocheirus stepping into the ring*

Most recently they’ve deduced Spinosaurus fed like a giant stork.

I love how your enthusiasm seeps through even though you're trying to look like a super serious biology professor.

2021: This video needs to be renamed MDAW (My Dinosaurs Are Wrong). I'd really like to see an update.

"We don't have as much of the tail as maybe we would want-" just wait, past-Steven. 2020's got a gift for you.

Not bad. Notice how the final model still stands its hind legs. It probably could move bipedally. Maybe not as well as other theropods, but it could still manage. It probably switched from standing on all fours and bipedally depending on what the situation required. I'd also like to say that, since this video was released, Spinosaurus has only gotten weirder. A new study this year now suggests that it's jaws were far more flexible than that of other theropods, and were similar in some ways to those of Pelicans and snakes, enabling them to stretch their jaws wide enough to swallow even small dinosaurs whole. This thing really was a freak of nature, which is why it remains my favorite dinosaur.

At the time this was made, I am so, SO glad they didn't use the quadrupedal Spinosaurus position, which is now outdated.

Spinosaurus went from a big trex with a spine to a giant crocodile mixed with a duck

Spinosaurus has always been my favorite dinosaur ever since I saw Jurassic Park III as a kid. In recent years, I've found that the increasing information we've found about Spinosaurus makes me love it even more.

I've been playing a lot of jurassic world evolution lately and I think it would have been much cooler if they had gone with this more accurate spinosaurus instead of the classic Jurassic park spinosaurus. It's got a lot of bright color on the crest and it's very pretty but it's like you said where it's just t-rex with longer arms and a funky back.

I love what people say about the new study. For every other discovery: "Oh cool." A discovery that changes a fundamental thing about our knowledge of that dinosaur/dinosaurs altogether: "That seems pretty shady and ridiculous. I don't think it's true."

new Spino is still cool but in a different way. I try to imagine what reactions would the XIX and early XX century paleontologists would have if they saw how "their dinosaus" would actually look like.

So cool that this is already out of date, spinosaurus gets more badass every year!

I feel like this needs to be revisited! We now have more of the tail!

Spinosaurus needs an update again.

The knuckles are too frail to walk on; they'd break. His legs were long enough to walk on but still shorter than the other therapods. He definitely couldn't walk on all fours tho! 16:40 also he is so freakin cute hahah

Can’t wait until this gets reuploaded on the new channel and gets updated!

New Spinosaurus, a badass super crocodilian, makes a lot more sense and I find it much more interesting than the skinny t-rex theropod of old. The s-curve spine seems like it'd be exceptionally good at lunging forward, kind of like an egret, and the posture even makes a lot more sense as I'd imagine it dragging its belly like a crocodilian in most cases. All things considered behaving more like a crocodile makes its most distinctive feature seem perfectly sensible! I only wish I could see the real deal in action.

I think the game ARK Survival Evolved should be looked at in this series. Not necessarily to criticize their lesser depictions (ie: the Dilos right out of Jurassic Park) rather to look at their oddly accurate ones (Trike, Spinosaurus, Utahraptor, etc) Plus in this context you'd get to go over actual locomotion. If you need to be happy again, speaking of that game, it supports Virtual reality and you can tame and ride most dinosaurs including the Spinosaur. You can't feel the touch, but you can get crazy close. Also I'd love to see someone with Paleo cred criticize their Theropod hands always facing down :-D

And now there's even more weirdness about spinosaurus 😂

This is such a weird animal. So much of it doesn't make sense when you think about it in terms of it being on land, and with the new information basically making it a pelican alligator is just crazy to imagine.

Now you need to do a Your Dinosaurs are wrong of this episode, :)

Seems like they fill the same general niche as a bear. It moved mostly on all fours and could rear up on their hind legs and even walk around like that for a while, but their not dexterous that way

Imagine a Spinosaurus swim tranquil in this posture on a Lake. No imagine a Spinosaurus with Feathers. Now you have a really big Duck.

6:45 And now we do. I love how we keep updating the spinosaurus (and dinosaurs in general) with new and new findings. It's like a never ending journey :)

Steven: We don’t have much of the tail 5 years later: H E T R I E D I T

I'd love to see a carnotaurus

once I saw that figure I thought EVERYTHING ABOUT THAT IS WRONG lol

Spinosaurus: " I'm the biggest, most scary looking carnivorous dinosaur ever!" Me: "So what do you eat, big sauropods?" Spinosaurus: "No, um....fish...."

You should do an episode on how spino was too big to walk and what that means for future reconstructions

0:43 OMG I'm there! :D

It would be awesome to see an amended version of this sometime. I understand that the recent discovery by Ibrahim, et al. didn’t blow up our entire notion of Spinosaurus (which would “necessitate” a much more in-depth breakdown on Steven’s part), but rather confirmed what many of us had long suspected, but nonetheless, I would enjoy hearing Steven geek out about it.

2023: "Wings...apparently it could walk, swim and fly"

6:45 “We don’t have as much as the tail as we want.” 2020 discovery: Are you sure about that?

You need to revisit the Spinosaur because new evidence has shown the tail has much more verticality than research in the last thought. I also am wondering if the Spinosaur could have been mostly aquatic, split between swimming in deeper waters, and wading through shallows, while rarely visiting land? Maybe that's totally wrong though.

Did other spinosaurids live the same way? Did Baryonyx have webbed feet and walk on all fours and have pressure sensors in its snout?

6:39 "We don't have much of the tail as maybe we would want" It's Always Sunny in the Cretaceous

Spinosauridae in general, along with Abelisauridae, contain my favourite prehistoric dinosaurs. I love how convergent evolution just looks at a Spinosaurus, then later looks at a pelican and goes: yeah, different but the same. I really love these softer, more round restorations, makes them look like actual animals.

This video requires a Follow-Up.

5 years later: "Oh no..."

Spinosaurus got updated yet again and now this is on my recommended

I know this was before the study about Spinosaurus having a tail sail, but I'm surprised it wasn't even raised as a possibility even though ichthyovenator is shown with a tail sail while bearing a less prominent sail overall.

They've revised it again, and come to the conclusion that Spinosaurus was likely bipedal. Which makes a lot more sense, for various reasons. The biggest reason among them being, not a single relative of Spinosaurus is a quadruped.

I saw the PBS documentary on the reconstruction and found it really interesting. I will admit to being a bit dubious about the 2014 reconstruction. I guess I feel there's no precedent, exactly? Every other theropod, including closely related species like Baryonyx, walks on two legs. I would really like to know more information on a Spinosaurus's hips, because it seems awfully extreme to me that this gigantic creature is the only one who made such adaptations, despite having physiology (bones) that overwhelmingly point to it being bipedal. Now, granted, it could well be that Spino being reconstructed like this means its brethren will get a similar overhaul and we will see quadrupedal Baryonyx and the like. Knuckle-walking also strikes me as a little far-fetched; usually there is reinforcement for such mechanisms (like Megatherium's magnificently fused radius and ulna), and the Spino's elegant foreclaws seem better suited to grabbing and holding down fish to assist the jaws. I just can't think of any other example on the Tree of Life where the broad strokes are there, but something is fundamentally reversed about the physiology. I'm not opposed to it on grounds of vanity or anything, but it just seems to stick out too much to me. It's too different. But I'd like to hear any rebuttals to my concerns. Your video certainly made an excellent argument for how such an animal not only could have lived but thrived.

I almost think a redux episode needs to happen just because of how much of what we know had changed since this episode was made.

"Spinosaurus isn't as cool now that it's turned out to be aquatic." Crocodilians: Are we a joke to you?

suggestions for your dinosaurs are wrong: monolophosaurus, carnotaurus, orlorotitan, sinorinithosaurus, carcharodontosaurus, and giganotosaurus

Apparently a new study found that due the Chimera nature of the Spino model uses....they accidentally missed-sized the hind legs in according to the other bones used. The rear legs need to be a out 27% bigger. Giving Spino better capability to walk on it's hind legs like a standard Carnivore. BUT it could still walk on 4 legs like some aquatic herbivores. Would be useful in shallow water and fishing!

Imagine if we went back in time and the dinosaurs looked EXACTLY like the very first reconstructions, that would be hilarious

Seeing how much spinosaurus has changed since yesterday, you should release a remake.

this spinosaurus looks so much cooler than the bipedal spinosaurus

This is cool! You do any creature? How about Machairodus?

You are massively talented

Really great talk on Spinosaurus which is one of my favorite dinosaurs and Steve is one of my favorite speakers on dinosaurs. Great job!

While perhaps not 100% accurate, you can ride a Spino in Ark: Survival Evolved. :) They're all kinds of fun, and really great swimmers. :) I'd suggest you give it a try, if only to enjoy all the well rendered creatures.

By the way, the 2014 bones of Spinosaurus that seemed showed it was a knucle walker were actaully from a differnent spinosaurid called Sigilmassasaurus, so it's inaccuarte to say that Spinosaurus' legs were really short and it walked on 4 legs only. This was found out this year.

12:31 2020 came in to say, yes the tail is adapted for life in water, but not like crocs

And then came 2020. Spinosaurus partially evolved to throw scientists for a loop, I'm sure, but I love it so much!

Of the Megalosaurians, I think Spinosaurus aegyptiacus is my favorite!

I find kinda hard to believe that no one has ever suggested that spinosaurus's jaws and the mouth of a salmon look so much alike.

There is now a new study by Ibrahim that shows a new eel-like tail

I love that I discovered this in 2021... just need an update to this video

DUDE. I have so much hype whenever I see a new YDAW in my inbox, and I watch it immediately. This was nowhere close to a disappointment-in fact, it's one of your best episodes yet. Keep on being awesome, and I look forward to the next installment. oh yeah and if requests are a thing then Leptoceratops cause it's my favorite dinosaur, haha

It's so weird how birds are technically ornithischian (bird hipped) by definition, but actually descended from the saurischian (lizard hipped) side of the family tree of dinosaurs.

I used to think spinos were so boring because they were basically just "trex + sail" in toys and media, so I never looked into it. I can't believe I ever bought into that lmao, but I'm so glad paleontology is progressing smoothly and we're getting better ideas of how these amazing creatures might have looked.

This is me at Thanksgiving dinner talking about dinosaurs my family doesn't care about, getting more and more excited with each breakthrough and fact I mention.

Spinosaurus is my favorite animal that ever lived! :)

To me, the new spinosaurus looks bad ass

The Spinosaurus has been my favourite dinosaur since i was a child. It beeing semi-aquatic makes it even cooler in my eyes.

I've only watched two episodes so far and I'm in love with this series. Keep up the awesome work

1:21-1:25 If you read this below, you'll perceive those 5 seconds in a WAY different way Like what you'd see in a bee movie attacking a city

6:39 MEGATHERIUMUS SPINUS!

i love the new spinosaurus it looks so cool

"Enormous aquatic hyper-carnivore" is way better than "T. rex with a sail"

I think it's far more fascinating to find it's a semi-aquatic creature, filling a niche something on the par with a crocodile. philogenically, how do they relate to something like the pliosaurs or mosasaurs??

It seems like the developers of Ark did a really good job modelling Spinosaurus, it looks almost exactly as described in this. Absolutely terrifying up close.

Cocerning some early reconstruuction attempts, an illustration occured which showed a Spinosaurus with a vertabrate sloping down from its head to the post- hip beginning of its tail. The extended spines looked quite as they are shown today, BUT: the skull in the head was way off; it looked like it was a tyrrannosaurid. Probably, it was used because the skull's actual shape was not known at that time, and the backbone was also reconstructed to run horizontally rather than at a slant.

Little did they know, this would be outdated in like a month
