Evolution of Triceratops LIVE Lecture with Q&A

This is a new and improved version of my Triceratops lecture.
🦕 In this episode, we unravel the remarkable story of the Triceratops, from Small peaked lizards to becoming some of the largest creatures to ever walk the Earth.
📜 Unearthing the Past: First Discoveries
We kick off by revisiting the thrilling moments of the Triceratops' first unearthing. Join me as we step into the shoes of the intrepid paleontologists who unearthed these colossal remains, piecing together a puzzle that spans millions of years.
🌿 Branches of the Family Tree: Evolutionary Lineage
Discover the intricacies of the Triceratops' family tree. I delve into the evolutionary relationships that tie this creature to its distant relatives and showcase the fascinating adaptations that allowed it to thrive in its changing world.
🌳 A Glimpse into Ancient Habitats: Triceratops' Environment
Venture into the diverse ecosystems that once hosted these majestic creatures. Through vivid descriptions and a captivating slideshow, we journey through the landscapes of the Late Cretaceous, where the Triceratops roamed alongside other ancient giants.
🌌 Facing the End: Brief Glimpse at the Extinction Event
Our journey wouldn't be complete without a glimpse into the cataclysmic events that reshaped life on Earth. I touch upon the theories surrounding the mass extinction event that spelled the end for the Triceratops and countless other species.

I appreciate the free education! Thank you very much.

[@takekingsolxll6299]

Agreed

[@duanesamuelson2256]

If i caught what you said correctly about the jaws not able to move side to side the probability of having multiple stomachs like cows is slim. Cows spit up from their 1st stomach and rechew it/grind it (chewing cud is a side to side motion). Multiple animals today eat very low nutrient diets with one stomach... elephants, pandas, giraffes, and sloths, all with one stomach. Something to consider is they would eat bones as well as the occasional small animal as cow's horses deer tortoises, etc, do today. The growth rates ,to me, would indicate they required additional minerals. If you went back in time it wouldn't necessarily be just the predators which might eat you.

[@violetberlin7663]

New study shows that the Psitachosaurus was most likely not guarding or babysitting all the babies. It’s now understood that the larger specimen was still a juvenile and just happened to be caught in the same catastrophe. Its still an amazing fossil find which gleans a ton of information about their behavior, and a sad case of how brutal nature can be.

[@EmpireOfLuciferSatanson666]

[@warthogvanguard7292]

I love your “Evolution Of” videos. I know you don’t have too many of them but I could listen to you talk about the Evolution of Mosasaurus or Carcardontasaurus and the dinosaur debates, the relatives, teeth, the adventures you go on. It’s really good! Yeah these videos are long but they really do need to be long, it makes it better in my opinion because it does the topic Justice. Just letting you know I really like these videos.

[@warpeace8891]

Great question/idea by the young man about pack animals may only die one at a time for a range of reasons. It had not occurred to me before but I have seen many examples of a lone bovine skull in a field but never a group. Bovines are invariably pack animals. The reverse may also be true.... In tar pits, animals have been found in large numbers suggesting that they were social or pack animals but maybe some were only stuck in tar one at a time.

[@lavarclemmons1920]

My most interesting thing about the triceratop is from what I understand they kind of fed on other animals when they were hungry or when their food supplies were slow I wonder if that's true or not maybe that explains why they had heartbeat and rows of teeth

[@hobart0011]

Many herbivores such as horses have been known to eat small animals when they have the opportunity. I wouldn't doubt it. They definitely were able to physically.

[@Morpheus1984]

One tiny titbit of critique: the asteroid impact was 66 million years ago. at 65 the non avian dinosaurs were already a extinct a million years before.

[@hobart0011]

I do agree with this assessment

[@sladewilson8224]

Question about the triceratops. One study seems to suggest that fully grown triceratops was a solitary animal that preferred to live on its own were as the other study states that triceratops was a highly social animal that lived in large herds. With all the new information ,in your professional opinion was triceratops a loner or herd animal.

[@hobart0011]

I still lean towards solo trike tife style. I'm sure, like many solo animals today, there were animals that bonded and stuck together to survive better. Like brothers that never separated when they matured. Thanks for the comment!

[@owencarow2344]

Loved it, hope you make some more dino deep dives.

[@Rune_Scholar]

I think you got that backwards. Dracorex was thought to be a juvenile Pachycephalosaurus, and still is thought to be, specifically because we don't find juvenile Pachys. Such a glaring inaccuracy really undermines your presentation. Stygimoiloch, the next stage up from Dracorex, with more of a dome and receded spikes, then you have Pachycephalosaurus with a dome and very small spikes. Also, no, no juvenile Torosaurus have been found. That would have been a huge announcement. And yeah, I checked. I'm not saying that Triceratops and Torosaurus are synonymous, but if they are not, it wasn't confirmed by the presence of juveniles. Where are you getting this?

[@maynight2259]

very cool just what I was looking for....

[@arkwark22]

Triceratops have always been my favorite dinosaur, so I've loved reading books about them ever since I was a child. I didn't know there was more information about them till I found this, so I'm really grateful. Maintain your excellent work.

[@jezzusj]

I suggest that the explosion of bird life at the same time as flowering plants and insects is because birds eat insects.

[@jstewartproulx2179]

Probably a really dumb comment / question here... So t-rex had tiny arms and I assume other dinosaurs did too... Is it possible they were selected that way over time because their prey had nasty powerful beaks that could literally dismember them?

[@hobart0011]

This would make a lot of sense. Sue the rex had an arm ripped off and healed. Could be because of each other ripping them off. Great comment thanks

[@cacogenicist]

Very unlikely. Most likely smaller arms were initially selected for, for issues of balance -- heads get bigger, arms get smaller, or rather, smaller arms enable a bigger head. A bigger head was more useful than those arms, for a biped like _T. rex_ that needed crushing power. And then at some point the arms are pretty useless, and so it's possible for _even smaller_ arms to not be selected _against,_ and so they could get even smaller. Had the asteroid not struck, perhaps the arms would have ended up like the vestigial limb nubs on a boa constrictor. It's also _possible_ that those tiny arms continued to have some sort of function -- who knows, they might have flapped them like crazy to impress mates. Maybe the arms were even brightly colored.

[@matthewbadger8685]

@@cacogenicist the arms on trex are extremely thick-boned, robust, and muscular, so it probably had a purpose for them. I imagine that tiny manipulating clawed nubs on the torso would've been useful during mating and whilst struggling with prey, sort of as a means to increase friction.

[@StrotherPitzke]

I like this very much. But come on, how many times can you misspell ‘meter’. And 17c is not 67f and 67f is not 17c, which one is it?

[@hobart0011]

Thanks. I did notice the miss spelling for meter, but had not realized the temp problem. I am going to need to watch this again and look up what the true information is. Thanks for the feedback. It helps me improve for future content

[@Rune_Scholar]

No, he is not an actual palaeontologist. He made several elementary mistakes in this presentation, such as getting Pachycephalosaurus and Dracorex confused and claiming that it was thought that Pachycephalosaurus was the juvenile form of Dracorex-it was the other way around with Stygimoloch being a middle growth stage-and claiming that this has been disproven when it has not. He needs to study the ontology and the malleability of Marginocephalia headgear. Likewise, he claims that we have Torosaurus juveniles, which to my knowledge, we do not. Sorry for how "spicy" this initially sounded.

Where is jugaloceratops in the ceratopsians family chart which you have shown

[@hobart0011]

I've have not heard of this animal till now. Just as the name suggests, the jugals developed into horns. Really cool, but I do not know the answer to your question. Probably closer related to the styracaceous than the triceratops

[@TITANSofTheEARTH]

I watched some of your lectures - very nice and interresting. At the Q&A i find some answers a bit short for a pro. When Triceratops has such a humongos nose system , he probably smells great!? And like 99% of herbivores if one sens is great the others lack. Instead his opponent carnivore T.rex seemed to have great smell and even greater eye sight. Or not? Then their teeth an growth. Sauropos have compared to ceratopsians simple teeth but the also had batteries of them growing new every 30 days...what is also impressive. Then they have ripped the plants of without chewing...no time for it^^ So they where probably hindgut fermenters. One key to their massive size. Ceratopsians with their massive teeth and jaw muscles ...probably foregut fermenters? For comparison for living animals ceratopsians and elephants have massive heads and chewing muscles. Elephants have one stomache but with several parts. Elephants are also hindgut fermenters. Massive amouts of low energy food per day. So Triceratops and especially sauropods (with their tiny heads) must have had some more effective digestion system... otherwise the day has not enough hours to eat enough.

[@hobart0011]

I think this is great information. Thanks

[@inalaop]

great presentation; of note though, the asteroid hit 66 million years ago, not 65....

[@robbie_]

I don't understand how volcanoes cause a "greenhouse effect". They release a lot of sulphuous gases, the haze from which reduces solar insolation. It is at least neutral in terms of temperature. This is just the paradigm of the month I guess. A "theory of everything" for climate. Other facts are probably more important.

Do we in fact have well-sexed examples of Triceratops and Ceratosaurus, or Dracorex and Pachycephalosaurus? Is there a non-zero possibility that the two pairs of examples are in fact examples of sexual dimorphism? For example, has medullary tissue ever been inferred in these animals? Other evidence of sex?

[@hobart0011]
