[@sampagano205]

This definitely gives me a new appreciation for herrarasaurs, because even though the missing link thing isn't actually really accurate, this is definitely the dinosaur that feels most "in-between" what people usually think of as reptilian traits, and the things that would go on to make the dinosaurs so interesting as a group.

[@upsyturvyy]

I love how in the beginning you used baby alligator noises ;w; so cute. and the animations are spectacular as always!

[@ettinakitten5047]

Quite a plausible noise for baby dinosaurs, considering both are archosaurs.

[@c.r.blankenship9040]

21:30 My dogs would sometimes get into spats with each other that would occasionally result in minor injuries. They weren't trying to hurt each other, but their teeth did occasionally do some damage. What's interesting though is that a lot of times, if someone left a tooth mark on someone else, there wasn't always a corresponding tooth mark (because they weren't actually trying to hurt each other). Rather, they had simply snagged the other's tooth on, say, the top, but not on the bottom. I might guess that these Herrerrasaurus bite marks are perhaps a similar instance, where neither Herrerrasaurus was trying to seriously injure the other, but they fought, and somebody got caught on a tooth a couple times.

[@callusklaus2413]

That's a really interesting take, but begs a pretty difficult question: Did these animals have complicated social lives to facilitate play fighting? Dogs have some pretty complicated social behaviors working under the surface, can we give credit for similar behavior in basil dinosaurs like this?

[@ragnarr7968]

I think injuries while playing with possible mates or even siblings while young is indeed possible, I highly doubt that an Injury that leaves a mark on the bones come from playful fights. If your dogs would bite each other with enough force to leave a mark on the bone, you would probably go visit the Vet, since it would literally not just be a deep scratch, the injury would penetrate through all layers of skin and muscle. But that doesnt rule out the possibility that these marks may come from an severe accident while playing, but since there are 3 marks I kinda doubt that.

[@erichstreberg7101]

Id be interested in the bite force required to leave a mark in bone though. Play fighting maybe various nicks, but to puncture a skull must take a lot of pressure.

[@selgehrman7573]

I think the most surprising thing I learned this entire episode was that Eoraptor was a basal sauropodomorph. Other than that, the look at the Triassic ecosystem was phenomenal, it's so interesting to see what kinds of odd creatures lived back before the dinosaurs took over.

[@KazunariGames]

It's been so since 2013. The majority of papers on early dinosaur phylogeny since then recover Eoraptor this way

[@Ryukai-san]

So basically, This area where Herrerasaurus lived was the Triassic Equivalent of Africa's Rift Valley, along with there ecological equivalents of Lions, Hyena's Wild Dogs, Crocodiles, Hippos, Warthogs, Wildebeests/Zebra's etc. It's fascinating when you consider how much time has passed but the same environment result in such similarity in the composition of prey/predator types/niches. Guess it's like the old saying "the more things change, the more they stay the same". 😉

[@Jpteryx]

If you consider the climate, maybe more like the steppe around the Black Sea.

[@Dr_V]

Here's a few personal thoughts about the bones you've talked about. Disclaimer: I'm not a paleontologist, just a radiologist who studied a bit more bio-mechanics and comparative anatomy than the average MD (a while ago I got involved in some inter-disciplinary studies that required such knowledge and then kept dwelling more into it out of personal curiosity). 05:48 Compressed vertebra like that suggest a higher length-wise load on that segment, either from supporting the upper body weight in a more upright bipedal position or just from kinematic muscle loads stabilizing the torso during bipedal motion (postural loads while walking). 06:03 The large grooves on the spinal processes in the same lower back area are strong ligaments insertions and the upper "lips" are insertions for strong postural muscles, proving that the area was a pivot/anchor point for the main kinematic chains of the animal (a kinematic chain is a group of muscles functioning together as a dynamic system, contrary to popular beliefs very few muscles work independently of each other). You can see somewhat similar modifications (on a much smaller scale, of course) developing in the spine of human athletes or heavy labor workers. 06:55 Those sacrum vertebrae suggest a transitional postural adaptation, possibly from quadrupedal to bipedal stand (and locomotion) within a relatively short time span (on the evolutionary scale). What you call "ribs" are actually the transverse processes of the vertebrae, more often called sacrum wings when completely fused together (like in adult humans). The small number of sacrum vertebrae suggests the pelvic bone rotated downwards without becoming wider (yet), requiring the 2 articulated vertebrae to thicken transversely (or "deep top to bottom" like you said) to be able to support the increased loads. All these bones (pelvic and vertebrae) are more metabolically active than long bones and consequently able to remodel (a bit) even during the lifespan of one individual, so such a transitional adaptation could be as fast as a few dozen generations. The large "boot" of the pelvis as you called it also supports this theory, as the simple widening of an existing feature is much quicker than a full remodeling of the bone, probably triggered by muscle development in adaptation to the postural change (that area functions exclusively as a muscle anchor and it's also able to widen a bit within the lifespan of a single individual as well, even in humans). 10:42 I thing you are correct in that assumption. Postural ligament insertions are far harder to change than the free moving parts of a finger/toe and the fact that a vestigial finger retains a large base proves that part serves as a structural leaver insertion, probably anchored laterally to the tarsus by short ligaments. A parallel with human anatomy is the pinky toe, the loss of the entire 5th digit has no impact on the function of the foot as long as the 5th metacarpal head is intact (some anatomists theorize that the pinky toe is becoming vestigial in modern humans and we may end up "losing" it at some point in the future).

[@lyssie___8126]

[@semaj_5022]

Great read, thanks!

[@DinosaursReanimated]

That yall go into such technical detail and that you have found and captivated an audience with this much palentological detail is inspiring.

[@sukinardi]

hello there, I am a paleontology student from Argentina (it always amuses me to hear or read the names of the researchers who were / are my professors in a video from another country) your videos are really amazing, I can't believe that you are not a paleontologist (you have a better understanding of some animals than some people I know in the field), about using isotopes as a temperature proxy, the idea is that each isotope (O16 or O18) has a different mass, obviously O18 is heavier, so when the water evaporates tends take the lighter isotop (O16) and to leave a greater relative abundance of O18 in the body of water, (which latter forms the carbonates in the shells of creatures and eventually in the rocks) the higher temperatures more the water evaporates, I don't know exactly how is it calculated but that's the main idea

[@Eloraurora]

Thank you for elaborating on how the temperature estimates work!

[@laelaps5246]

[@Vulcano7965]

You can also use phosphates like (bio-) apatite (e.g. teeth) for oxgen isotopes instead of calcite in paleosoil. Less suspicible to later changes, these minerals are very durable and don't give up their oxygen atoms very easily. With calcite you have to be sure that it wasn't alterated.

[@akrocanth]

I remember first learning about Herrerasaurus on a tv series in the early 90s called The Dinosaurs! I LOVED the animation and art style in that show, I had it all recorded to tape and probably watched it hundreds of times.

[@paleoph6168]

It's not a dinosaur, but dang I'd like to see some sort of Pseudosuchian or Rauisuchian on this show. Also, the mascot dinosaur of the channel, Monolophosaurus would be rad.

[@billyr2904]

I thought it was a very inaccurate corythosaurus based on the shape of the Crest, because corythosaurus had a taller Crest. But I can see what you mean an orangutan. Also how is an orangutan watching this, well orangutans are great apes, but your just a human that called yourself 'an orangutan'.

[@dynamoterror7077]

WOAHWOAHWOAHWOAHWOAHWOAH… 52 degrees Fahrenheit MAXIMUM, in the TRIASSIC?!? Ok, that’s weird. Thanks for making this video, I have learned a lot about Herrera and the wacky environment that it lived in!

[@kR-qj7rw]

Thats the wildest part knowing ischiguslasto was cold

[@leoomas_]

So glad this was on Herrera! If only it came out a little earlier, recently have been working on a game and had to do Herrerasaurus concept artwork, glad to see my design ended up being extremely accurate compared to your portrayal!

[@AlexIsModded]

First I want to say that Herrerasaurus growth based on diet makes perfect sense to me. It's a reptile. That's what reptiles do, they grow based on their diet. I have three aquatic turtles, and two of them are the same age. One is dramatically bigger than the other. They used to live together, and the larger of the two would bully the other turtle away from the food. She got less food, so she ended up not growing as much. Since separating them, the smaller turtle has gotten a lot bigger. Since Herrerasaurus doesn't easily fit into several known families, wouldn't the next logical step be to classify Herrerasaurus as it's own family? It's not outside of the realm of possibility for an animal to be its own family with no other known species with it. That's not to say that the Herrerasaurus just came to exist without an ancestor, cause when it comes to evolution that's not realistic at all. But a species can branch off as its own thing. Early hominids are a great example of how this happened.

[@stroopwafelfalafel]

I wish I could find it, but I think there’s a paper from the last 10 years that makes exactly the same suggestion!

[@theorangeninja6486]

I believe that's what he means when he said it's been classified as a basal dinosaur as opposed to a stem theropod or sauropodomorph or some other such thing

[@LB-vf2hm]

I would like to remind you that herrerasaurus is much closer related to birds than any non bird reptiles, especially turtles, so despite a turtle like relationship between food availability and rate of growth being plausible, it's entirely speculation. Trying to draw scientific conclusions from common sense can be risky

[@rar7437]

I'm really likeing the fact that you're including other animals that lived alongside the Herrerasaurus in the video. It really helps artists like me get a good sense of the environment and potential situations/interactions we can depict the animals in. Please continue that if possible. Great video.

[@superscatboy]

I only found this channel today after it was recommended after watching something else related to dinosaurs. I'm not even a big dinosaur fan or anything, but this stuff is *insanely* engrossing, and I love it. It shows that a lot of effort goes into making these videos, and it's appreciated.

[@Rahru]

"... their fingers could extend nearly perpendicular to the hand, and I don't know why I'm trying to do that, because ours don't." So, if I can do that, am I retaining a more basal trait or is it a future derived trait? (Not that my bloodline is going anywhere, but hey, I just want to speculate)

[@Eloraurora]

It's hypermobility. Which can be heritable, but given our current ecological circumstances, not a huge influence on your offspring's survival. Unless we come to a underground-bunker style of apocalypse, in which case you might give rise to generations of flexible spelunkers.

[@TheRunningLeopard]

I also can do that and it’s hyper mobility but could also mean you have some sort of connective tissue disorder. So, honestly it’s probably a future derived trait since I doubt people with hyper-flexible hands that signify a connective tissue disorder of some sort would have survived that long if having to run away from threats. (If it’s just regular hyper mobility tho then honestly, it’s probably just recessive.)

[@jacobcox4565]

Babies have super flexible ligaments. When babies grow up, their ligaments harden a little so they have the ability to stand effectively. Sometimes, the ligaments don't harden due to random genetic mutation, thus hyper mobility

[@eljanrimsa5843]

I'll echo your own call for more Triassic content. It may lack the big charismatic megafauna of the Jurassic and Cretaceous, but the experimental weirdness, plus the drama of big-time dynastic conflict and turnover gives it a real charm all its own that no other period in the history of multicellular life on earth can really echo.
