It's amazing how many times dinosaurs evolved into quadrupeds from bipedal ancestors. Sauropods, ceratopsians, ornithopods, thyreophorans all started out being bipedal.
I notice quite a few humans going this round too.........granted the quads they are on are mobility scooters. Well actually I'm the only 45 year old I know that doesn't own a car, never had a drivers license and walks everywhere...............hell I'm the only adult I know that does this without a court order.
@@valivali8104Im not sure that is entirely true. Some research has suggested that Megatherium may have been bipedal. And many Ornithopods seem to have used four legs when feeding but probably still ran on two! The more likely case is that if you are large and your food is on the ground, having a lower body plan makes it easier to reach your food.
One thing that always amused me of late ceratopsids is how they repeatedly filled in the same niche of modern bovids. Large, stocky horned grass browsers living in herds? Definitely another case of convergent evolution.
Don't forget the giant tortoises which are still around today They're pretty much the largest non-mammal native herbivores on their respective island ecosystems
Triceratops is probably my second favorite dinosaur. They just look so majestic, and powerful, like a tank on legs. It is interesting to learn that their family was also so successful, and comparing them as herbivores to others goes to show that there are lots of ways to get the job done.
Beak combined with ever growing teeth. A parrot combined with a rat.......but the rodent ability was in the molars........I hate that I will never know how these animals actually were.
I studied Zoology at uni, years ago, and I've always been interested in absolutely every facet of natural history and life on earth. Your videos are outstanding! They're so well done, so interesting and enjoyable. Great work!
I recently saw a video on Clint's Reptiles where he asked viewers what their favourite dinosaur was. Being obsessed with the creatures when I was younger, I thought the question would be easy, but the more I thought about it, the more I realized I didn't have a proper answer. The best I could to was to say that my favourite ceratopsian dinosaur is Styracosaurus. I'm always happy when the make even the briefest of appearances in video like these.
I’d love to see a video on the Evolution of Cycads. It would be interesting to see topics of genuses like Ctenis, Antarcticycas and Dioonopsis just to name a few.
First Anaceratops, then Monoceratops, then Diceratops, and then comes Triceratops. Then comes Tetraceratops, Pentaceratops, Hexaceratops and Heptaceratops. Then Octaceratops and Nonaceratops, and finally Styracosaurus. UPDATE: Oh, I forgot Leptoceratops, then Baryceratops, then Microceratops and Macroceratops!
I found this so fascinating. I've seen so much coverage in Paleontology media of creatures that are already famous, but not as much about how they evolved. I learned so much watching this video. Thank you!
I just wanted to correct you about that bit you said at 2:12 about all dinosaurs evolving from a therapod dinosaur in the Triassic period- I'm sure you probably meant therapod-like dinosaur but I thought I should clear that up for anyone confused in the comments
We can't assume a singular function for structures such as horns. Modern-day horned animals often use horns both for defense and male-male contests. An animal will use whatever weapons it has as need presents.
So many things we don't know..........and as yet the sexual dimorphism of ceratopsians doesn't seem so extreme.......which leads to so many more questions about them.
well why do you think they developed those "weapons" in the first place? You are correct, most likely for a variety of uses, however the horns came from a need for them, not the other way around.
@@piggymag1c that’s an outdated view on evolution having an endpoint. Horns evolved gradually by selecting for individuals with bigger horns. The reason the ones with smaller horns not surviving or at least not reproducing isn’t really known.
They're defense was to run away. They're battles for mates were locking horns. I think its safe to compare them to modern ungulates (deer, bovids, antelope). Horns also serve as radiators for cooling
Dude, your content is awesome! I always, always love your videos! Question: at 2:30 mark...Ankylosaurs were actually that big? Edmontosaurus is the second largest hadrosaurid known to date, right? I thought Ankylosaurus was a bit shorter, or is that Edmontosaurus is shorter than i thought?
I am fascinated by the early north American primate's that died out, they've been finding fossils like crazy and now they're just getting to know them crazy.
When I was a kid I drew Tyrannosaurus jousting with Triceratops and my triceratops was walking on its hind legs. My teacher told me ceratopsians would have never walked on theirhind legs. I can just picture her now if I told her about this video, smugly telling me that hind leg ceratopsians wouldn't be dueling Tyrannosaurus anyway because the era was wrong. Oh well. She's dead now so that kinda sucks. 🤷
I've wondered if any creatures of this family ever filled the niche of a beaver. Big head, powerful bite, stomach of steel. Possible paddle tail derived from elongated feather/scales upon the sides ofthe tail.
Please upload more videos more frequently when you can ! Love the content and I’m fascinated so much by prehistoric life be it dinosaur, reptile or mamal 🙌🏾
I think you mean the vast majority of (very) large herbivorous dinosaurs evolved back into being quadrupedal. The smaller ones often stayed bipedal, especially among therapod species who were mostly herbivorous. Even some of the big herbivorous dinosaurs like hadrosaurs were facultative bipeds. Also, smaller animals tend to have more species and fossilise worse, so I would imagine taking all herbivorous non-avian dinosaurs into account would have them being mostly bipdeal, or at least it being close to 50/50. But the large herbivorous non-avian dinosaurs were likely mostly quadrupedal. Obviously even more bipedal herbivorous dinosaurs would be counted if you include the birds of the Mesozoic.
Check out "Walking With Dinosaurs Remake || Third Chapter : Clash Of Dynasties", it's independent documentary about parallel evolution of Ceratopsians and Tyrannosaurids.
One of the illustrations of the triceratops had flowering plants included at 56 second of the video; I do not believe that there were flowering plants at the time of the triceratops; please confirm Moth Light Media.
Flowering plants, angiosperms, evolved in the early Cretaceous, and became steadily more common through the period. By the late Cretaceous, they were quite diverse and common, comprising about half of all plant species (it would be after the extinction that they would absolutely dominate in diversity though).
First of all, that isn't a Triceratops, its a Styracosaurus. Secondly, flowering plants evolved early on in the Cretaceous and became very widespread moving on (this is what Moth Light Media said in the video as well). Both Triceratops and Styracosaurus evolved during the Cretaceous, making them co-exist with flowering plants.

There was a theory at one time that the frill functioned as an anchor for massive jaw muscles so the animals could eat woody vegetation. The frill would have been mostly internal, encased in skin and muscle. What's the current status of this idea?
I just wrote an elaborate response to this that somehow got eaten by the algorithm before I was able to hit post. Basically, I agree. And I compared it to our own hyoid bone.
@@valivali8104 I don't know. Perhaps by relaxing the jaw muscles? A dinosaur jaw is organised differently than a mammalian jaw. At any rate, I'm curious about the current status of the theory.
_Kulindadromeus_ has typically been considered a non-cerapod neornithischian, meaning it would've branched off before the last common ancestor of marginocephalians and ornithopods lived. However, a recent study into _Jeholosaurus_ and the ornithopod family tree reclassified _Kulindadromeus_ as a basal ornithopod.
Does anyone know where can i contact this guy? I have a question for him about his video on the large flightless birds. If anyone else is an expert on the subject, please let me know
What is clade of animals with most it's species alive today that would be comparable in species size (estimated) to the Dinosauria clade during the lade Cretaceous?

I think saying 'putting them all in the same group is misleading' is a tremendous understatement.

Well, if animal is big and heavy, which big herbivores have to be thanks to bigger and more complex digestive track, they have to be quadrupeds.

fantastic video. Ceratopsians are awesome.
these videos are so good and always make me sad that we evolved so late and missed out on seeing so many incredible creatures
Not really though. We have some of the most amazing creatures ever today. We're just normalized to them, just as we would be to the dinos

Adding onto this, I know of at least one other group of herbivorous theropods as well, Therizinosaurs, and they were also bipedal.
It makes sense when you take into account the adaptations needed for being a massive herbivore. Like a big barrel gut, weight distribution etc.
