Although we did recover Chilesaurus among heterodontosaurs, we state in the paper (Norman et al 2022) that our dataset lacks theropods and we agree with the original authors of Chilesaurus that it is more likely a theropod

It won’t even necessarily need to be an “alien” paleontologist, as it’s quite possible that multiple civilizations and intelligent species have risen and fallen over the course of Earth’s long history.
Thanks for the video. I was surprised this dinosaur which put 100 year old of taxonomy in doubt isnt focused on. It seems like the kew to understanding the dinosaur family tree is uncovering more chilesaurus relative and a silesaurs that are transitional with ornithischians, as well as finding a complete pisanosaurus skeleton.
Imo, Chilesaurus was more likely to be a saurichian than ornitichian, because most of the feature associated with ornitichia it has have evolved independently in many theropod groups (beaks, herbivory, backward hips, four toes on the ground, etc.). Though experts probably know better than me.
This is the reptile/stem-mammal channel. Although I do agree, Desmostylia is a fascinating clade. Ben G. Thomas and Animal Origins both did good videos on it already.
Ha ha I thought it was Chinlesaurus until you said it came from Chile and I was like: what the hell, that ain't right. Certainly a weird critter. The idea of a ghost of basal ornithiscians liniage might seem a bit far fetched, but not really when you consider that we have Jackapil in the candeleros formation setting up a ghost liniage of basal thyrieophorians.
A very interesting and well done video about a weird dinosaur. Kudos to the narrator. I see why it is perplexing but I don't understand why it is seen as basal. Didn't a lot of the weird ball traits first show up in earlier dinosaurs?
Im gonna jump on a leg and say that Chilesaurus may have been its own derivation from the Sauropodomorphs, at least down here in Gondwana. That is, assuming we find some previous specimens that prove some kind of miniaturization process on them due to competition from true Sauropods. This may have been a little process that only happened in certain species while most of the big ones were more or less fine until the big carnivores started to pop up, Chilesaurus's ancestors may have survived by becoming smaller and nimbler in a convergence similar to the Ornithischians or the later maniraptorans but still carrying most of the adaptations for the fermentation of plant material that the Sauropodomorphs were developing.
This constant reshuffling of groups and families is fascinating, but admittedly exhausting. It's no wonder the public can't follow it anymore, and it will take years before we'll exactly constitutes a dinosaur, and if Sauropods will be the equivalent of what pterosaurs are to dinosaurs: related, but not true to branch. 😅

The likely evolved to serve a role analogous to incisors, which most dinosaurs lacked (with the notable exception of the appropriately named Incisivosaurus).
''taxonomic chaos'' is a good thing, the best part about science is you are never out of a job, because some one will find something that shakes the status quo, and the truth dose not care about the ego of a disgruntled scientist.
That was very interesting. I still find terms like Clade and Derived slippery though i get the rough idea. Would you do or do you know of a good 'taxonomy for dummies ' video ?
Oke… we got one weird dinosaur in jurassic world evo 2, now its time to bring this one in. For free or in dlc i really dont care i need this in my dino petting zoo (of terror en mutilation)!
Is anyone or has anyone decided to do the genetic analysis with the excluded branches of dinosaurs now included? I haven't looked yet at the studies done or done a little homework to see if anyone is planning on further studies. But if it is as you say, it seems like a logical and easy step Even if it's the most basal ornithiscian it doesn't look like early ornithiscians. Really? That is a pretty strange thing to say, is it not?
You can always expect South America, to be rich in weird species. And in minerals. And in Labors. And in everything that should have belong to it's people, but instead are own by British and American Wealthiest.
I might be saying complete bs over here, but chilesaurus might have been an ancestor to therizinosaurids. First off, they lived in Chile (modern day Europe), and therizinosauroids lived in Asia and North America, chilesaurus might have moved over to Asia, re-evolved it's until then unused third claw, and evolved a taller posture. Again, I'm kind of in the dark with this theory, but I think it is at least plausible.
Basal therizinosaurs, such as Fukuivenator and Falcarius, have already been found and they are not very much like Chilesaurus. Also, Chile is in South America.
I'm kind of inclined to agree with the paper that placed Chilesaurus as a weird, basal tetanuran theropod. It's features are certainly strange, but given that we know theropods evolved herbivory at least a couple of times it really wouldn't surprise me if we eventually discover evidence that it happened many more times throughout their evolutionary history. Really though, until we have a much larger dataset of fossils to draw on all the hypotheses are just as reasonable as each other.
Considering the just as weird therizinosaurs that even redeveloped the 4th finger for walking are also therapods, these superficially not as weird dinosaurs could be another therapod lineage that went back to hervibory
Chilesaurus was discovered in the Aysén region of Chile, which is where my brother was living for a while. He likes hiking and all sorts of outdoors activities, and at one point he took a lot of pictures of shellfish fossils completely covering the floor high up in the mountains, in the middle of nowhere, very far from civilization. There's so many paleonthological discoveries waiting to be made there.
I agree with its original classification of being a Tetanuran Theropod. Tetanurans are notable for having three fingers or less. Chilesaurus has two, with one vestigial. They also lack a predentary bone of ornithiscians and have a pretty large anorbital fenestra (Ornithiscians generally have it reduced or absent). I think Chilesaurus just throws people off due to it filling a similar herbivorous niche of basal sauropodomorphs and basal ornithiscians, and sharing some convergently evolved features with them. But the traits like having a long neck, a beak (which have evolved independently in many different dinosaur lineages), and its backwards facing pubis (which theropods like Therizinosaurs, Birds, and Dromaeosaurs also have) can easily be explained through convergent evolution.
Spinosaurus seeing how Chilesaurus is a competitor for the title of most confusing and bizarre dinosaur ever: *Finally, a worthy opponent! Our battle will be Legendary!!*
i still think so, because that produces doomed offspring that wouldn't survive the fetal stage even if lucky. None of the hybrids were related enough to eachother smh.
The debate over the dinosaur family tree is one I'm always excited to spectate. That being said, I hope we do find new fossils/new information/improved phylogenetic methods so the mystery can eventually be solved. 🤞
I know it's completely superficial but I'm glad to have Chilean heritage after learning about this dude. Just as fucked up as my family makes chile out to be
Different kind of species were discovered here in chile, some more stranger than others, its look like south america was always a laboratory for nature...greetings from chile, exellent video dudde...
Fascinating creature that surprises us with its relative youth; when we start talking about the relationships between the major groups, naturally all thought turns to the Triassic, but it just goes to show how much we still have to learn and hope that we can uncover significantly more basal ornithischians in our lifetime! Thank you for making and sharing
I thought its obvious that all these quadrupedal herbivore dinosaurs evolved from similar dinos that were omnivore but got to fully herbivore diet and started walking on all four to support thier weight over time. By the way, sauropods evolved the same way from similar light bipedal omnivores if you didnt know
Are you going to think of a suggestion making a RUclips Videos all about Geosaurus (A Marine Crocodile and/or A Sea Crocodile) on the Next Chimerasuchus Next Saturday coming up next?!👍👍👍👍👍⭐️⭐️⭐️⭐️⭐️
First of all, I do not support the "Ornithoscelida" theory. Secondly, I believe that Chilesaurus is a basal hypsilophodontoid (see below), which kind of explains the missing predentary bone. Dinosauria --> Ornithischia --> Cerapoda --> Ornithopoda --> Hypsilophodontia --> Hypsilophodontoidea --> _Chilesaurus diegosuarezi_
I dislike how much argument there is in the paleontology field because another of the time people are just guessing BUT that is what makes it absolutely wildly intriguing!
Baron and Barrett 2017 nested Chilesaurus basal to Ornithischia two years after ReptileEvolution did the same. The sister group of Ornithischia is the Sauropodomorpha, both members of the Phytodinosauria.
Maybe the main dinosaur 🦖🦕 clades are so close to each other when they diverged, they could produce a hybrid lineage that persisted on? It would explain why highest level dinosaur taxonomy 🗄 is such a mess if the clades were basically sister lineages that diverged at hyper speed.

I'm astonished. I would never have expected that such an animal lived during the Jurassic.

"Spinosaurus is the most problematic taxon"
