Good to see McLoughlin's book is still significant today, as it was such a game changer back in '79 when I ordered it and had it delivered to my house. His art style was a big influence on mine ....
I remember once wondering if ceratopsians had humps due to the recent updated reconstruction of psittacosaurus that had the head looking normal instead of the shrink wrapped almost frilled look I was used to. This had me wondering on how frill like the frills actually were.
Yeah, grasses first appear in Late Cretaceous, if there was something like a "grassland" before that, it would be covered by different plants, maybe ferns and horsetails?
Strange! The thumbnail reminded me of John C. Mcoughlin's bonkers idea! And the film WAS about the ideas of ceratopsian shield-musculature that JCM brough up in his book. Here's where it gets weirder: up pops an image I drew for a book on Dinosaurs back in the mid nineteen-eighties. The front cover of that very same book pops up directly afterwards (Collins Guide to Dinosaurs). I was its Art Director and did a few drawings for it -- one of them being the Triceratops based on the idea from "Archosauria". Sidenote: Collins refused to allow us (The Diagram Group) to put our name on the cover of the book. Our main artist put it instead on the Deinonychus tail on the rear cover. It's written in camouflage. 🦖
I love your take that these 'outlandish' ideas should not be dismissed out of hand. Rather than assume all extinct animals are just slight variations on forms alive today it should be considered that some of them may have been truly unique experiments in evolution.
I remember reading Archasauria back around 1980 and being fascinated by the unusual reconstructions. I know it's a long dismissed idea, but I've still got a copy of the old book in my library. 😁
I figured there doesn't need to be another extra series when I can just make all of the paleo fails 'normal' videos. Same can kinda go for the paleo mysteries unfortunately.
the thing that hit me hardest with this video was the fact that grass wasn't really a thing in the Mesozoic. I'm sitting here like15 minutes later in silence so struck.
I really have to ask if you guys are native Houstonians like myself because you guys really like using records. of the Morian Hall of Paleontology in your vids. I approve of this btw as HMNS deserves more exposure and attention as it's such a quality museum.
Interesting! I really enjoyed this video, thank you for it. I always imagined the big bony ceratopsian frills as combined display structures and neck shields. Even without the lateral horns and knobs, that is a big billboard that can be raised and turned at will and is maximized when in head-down frontal attack position. Paleo artists have delighted in adding colors and striking patterns, which would emphasize species differences, advertise reproductive status, and add to fierce appearance. When under attack by a predator, the neck would be ordinarily be a vulnerable site, but not when covered by a great spiny, bony shield. Having a mound of solid muscle filling the frill not only would immobilize the head as you point out, it would make an attractive mouthful for a big predator biting down from above. So there were likely some jaw muscle attachments on the lower part of the frill, but the head would be fully mobile and the great frill would be free to tilt and turn to best display and defensive effect. An immobilized head would cripple vigilance and food acquisition abilities.
I love John C McLoughlin's books, SYNAPSIDA, THE TREE OF ANIMAL LIFE and ARCHOSAURIA and especially for his drawings, however, I never could wrap my mind around an adult Triceratops having a fatty hump behind its squamosal bone shield which would as the narrator of this video so rightly states immobilize its neck or at least restrict its movements which does not make sense since it had a ball-in-socket joint in its neck for mobility of same along with its shield presumably for protection against predators although the variety of these shields in other ceratopsian dinosaurs obviously was not actively for defense against predators but for display or both. Up to this time I have been completely mystified as to the tall dorsal spines in spinosaurids and in hadrosaurids. This video offers a plausible explanation to me for the first time.
It was actually my cover. At first I was ticked off because he didn’t gave credit, but that was when I was too unaware for the end credits. Now, I’m glad he included the remix in the credits.
Yeah ! Another video on ceratopsian ; my favorite critters. Thanks E.D.G.E ! So the ceratopsian were back-heavy ? Makes sense. The weight had to be balanced between the front of the body, supporting the head's bony display, and the back. Moreover, an heavy, and probably muscular back would probably allow the animal to shift its body from side to side, while staying in place. That coupled with a flexibe neck, and we get an animal that could hardly get flanked ; or flee if necessary. . . Something halfway between a hadrosaur and an ankylosaur.
I have wondered for the last 4 or so years if maybe the frill had not a jaw muscle attachment, but large neck muscles attaching their large heads to the shoulders, like you see in many mammals today that have large horns having that shoulder hump.
Ornithischian life appearance is something I find interesting because they're relatively distantly related to basically anything alive today. Like birds give us something, but unless the ornithscelida hypotheses is confirmed, which seems moderately unlikely, they are literally as distantly related as any two dinosaurs possibly could be.
If I understand the tree right and the distances in time, Birds and triceratops are about as closely related as we would be to a modern lineage of gorgonopsids. Which I hope gives some perspective on the sheer amount of time were talking about.
Good point regarding appreciating “unusual” thinking. The only thing we are truly sure of, is that we have no idea what any dinosaur actually looked like. Quadruped dinosaurs in general are still mostly depicted as too mammalian for my taste, with loping, slow movement. Logically they’d be more bird-like/reptilian. Even chameleons are a hodgepodge of very slow and very fast movement. Yet we never see a triceratops scratching at the ground, a sauropod bobbing or tilting its head, etc. You know, bird stuff.
I bet T-Rex wishes triceratops had a big meaty hump. It would have imobilized those dangerous horns and added an extra 3-4 hundred pounds of tasty meat.
So this is the other Jon who was a paleontologist and not the music artist who I primarily knew from the Song "So Close" which was from the movie, Enchanted. How interesting.
Oh,I didn't The Isle release a another neck tumor dinosaur,like the Trike. Also isn't E.D.G.E just the greatest with thier thumbnail and titles,cause their thumbnails and titles are so good,that they make the video so good.
2:27 My first thought: To what end? Why would an herbivore need a biteforce that extreme, especially when its horns would be a far more useful weapon in combat.
Horns are more for combating against members of your own species, even modern ungulates will kick and stab with their hooves at predators, than use their horns/antlers. But yes, no herbivore needs a biteforce THAT strong. Unless it was chomping oak trees in half.
@@austinhinton3944 Thanks for that info. I have a passing interest in the subject, so my post was moreso a reaction based on my impressions than a statement of fact, just to make that clear. Always nice to learn something, appreciate it.
I think there was a point where feathered therapods where laughed at, the debate on whether dinos we're warm or cold blooded went on about a century I think
What if, since most ceratopsians were larger and probably slower than other predators, the frill was used to protect the neck and preventing large carnivores from biting the back of the neck?
I'm not saying that ceratopsians necks were like this, but the argument that it would immobilize the head isn't a good argument. Muscles aren't immobile lumps of flesh. They are flexible, soft, compressible, and stretchable. Their heads would still have plenty of range of movement if this hypothesis were true.
@@EDGEscience it would have reduced mobility for sure, but not immobilized it. And there would certainly still be enough mobility for the animal to do what it needs to do.
