Sauropods were such magnificent creatures. I remember a Brazilian palaeontologist theorising that Ibirania might have lived in patches of vegetation across a larger desert and travelling between similar patches during a monsoon season, like it were islands on a shallow sea. An interesting idea, not sure if it could ever be tested though. No, not the Spanish J to a Portuguese name...

Since when did the make sauropods cute?

If these guys never went extinct I’d so have one as a pet

We have to wonder what would have happened to the dinosaurs if the Chicxulub impact hadn't happened. It's becoming clearer that it isn't the severity of the environmental devastation that is principally responsible for mass extinctions, but the rapidity with which those changes take place that is. Animals and plants can adapt to conditions of extreme heat and cold, dry and wet, if they are given the time to do so. Perhaps, if they had had a few more millions of years to shrink in size a bit, dinosaurs other than birds might still be with us as part of modern fauna.

I had heard of Ibirania when it was first described, but I had no idea how much of an anomaly it was for a dwarf sauropod or that it gave us the first fossils of parasites within their hosts. This is why I love this channel; I always learn something new and interesting!

My favorite cryptid animal as a kid was Mokele-mbembe, as I've always loved dinosaurs. The idea that maybe a small group of sauropods had somehow hung on deep in the jungle just completely captured my imagination. I dreamed of leading an expedition to find it lol

Very interesting. I'd never heard of these before. I like that you've bucked the trend and actually have a human being narrating your videos. Good job.

Yes finally!

I hate to be pedantic but I gotta say it: it is pronounced EEbirania, with the "ra" being the tonic syllable

Thank you very much for this

Another amazing video!

A friend of mine don't see the appeal of Paleontology ... But i mean, a handful of rocks taught us this much ! There're millions of years's worth of knowledge laying under our feet ; just imagine what they can teach us !

You know, rather than the air sack structure being vestigial in Ibirania adults, it strikes me as more likely that in their arid environment that was hot enough for ectothermic predators to become dominant in the ecosystem, the thermoregulation function that would normally allow them to survive despite extreme gigantothermy was coopted to allow sauropods to survive with smaller sizes but greater ambient heat.

Brilliant video once more. Just didn't quite get how it evaded predators, despite the arid environment.

Outstanding video brother!

Please make a video about trassic era of India

Imagine an enviroment so harsh that the land crocs start fighting their way up the food chain. Dinosaurs were pretty crazy when it comes to efficentcy and being able to live in some hot and resource scarce enviroments. As a mammal I shudder to think of the conditions that forced dinosaurs to be that small, and for the land crocs to become so dominant in the enviroment.

I’ve got some great ideas and some great suggestions for you to make KZfaq Videos Shows about some more Prehistoric Extinct Crocodilian Species, such as Lazarussuchus, Plesiosuchus, and Metriorynchus adding that to the episodes on the next Saturday on the next Chimerasuchus coming up next!!👍👍👍👍👍⭐️⭐️⭐️⭐️⭐️

I wouldn't mind see those small dinos be brought back to life.

Giant #1: Why, he's barely enormous! Giant #2: He's merely huge! Ren and Stimpy: The Littlest Giant.

9:41 I do t think the spots are plausible on furless sauropods but otherwise this is one of the more aesthetically pleasing paleo-paintings I’ve seen in a while

You know with all of the “tiny” sauropods such as Ibirania, Magyrosaurus, and the Ecuadorian Yamanasaurus. I really wish that somehow one of these tiny little guys could have survived into the Cenozoic. I mean they are the size of Cattle or Giraffe’s so they aren’t small, but still the fact that some sauropods were adapting to fill similar niches to that of hadrosaurs is certainly interesting. Imagine if a lineage of these guys survived into the Pliocene when the America’s collided. It would have probably led to them filling similar niches to that of Mammoths and Mastodons only bigger. Not by much but definitely bigger, like Paraceratherium sized animals regularly just walking around the Americas and possibly Eurasia.

Another great video 😎

Some of the most sauropod rich formations there are can be described as arid or semi arid, such as those in North Africa and South America during the cenomanian. The Baru basin must have been something else entirely if it was that scant with resources that the sauropods could not rely on great size to get then through the hard times. It must have been a brutally harsh enviroment.

I wonder how fast they grew up, perhaps them reaching such a size made them more abundant or easier to tolerate losses

Aqui é o Brasil tropa

Very interesting. Thank you

Great work once again!

Has it really been six months since your last upload? This is concerning. I've learned more from you than any other paleo-related channel. I rewatch this material endlessly and still pick up new information. I hope you come back soon.

I subscribed

Oh yeah: "just 6 metres" and "just 2 tons", positively tiny!

Can u make a video on taxonomy/taxonomic ranks?

Since the air sac system made the bones lighter and this animal was rather short, do you think it was relatively fast also?

Dinogoats

I wouldnt be surprised if it had some odd adaptation for defense that wouldnt fossilise. Think a skunk's spray, the in-taken toxins of some birds, or the quills of a porcupine.

Nice but could you make a Video on Furucatoceratops the new Ceratopsian of 2023 if you can

Perhaps a tiny sauropod could use poison to protect it from therapods. Imagine tiny poison sacks all throughout the skin waiting to be bitten and popped. Or perhaps they just ate something toxic and built it up like a monarch butterfly does. Or what about quills that made them look like porcupines. Or some kind of chemical weapons like a skunk, or nasty llama. They had some kind of trick, but what was it?

Could the smaller sauropods Gallop or run?

I miss the old narrator

11:15 - Plague of Madness 😟

It's "José" pronounced like "Joseph" not the Spanish "Jose(Hose/Rose)"

Dwarf titanosaurs? Bit of an oxymoron.

I miss the nasal voice 😢

Look I'm coming in defense for the little guys, every one understands that Amargasaurus, Brachytrachelopan, and Nigersaurus muscled beside some very tough predators in their ecosystems. So why are we handing this much credit to another "Fern-Gully" sauropods rather understanding what should have realized?

It's pronounced "ee-bee-RA-knee-uh".
