Hey Jonathan it's Tim Traut , are you going to put something up on the uwo meeting the other day hope you had a good trip home with the fam it's great to meet you

The horns were bone, but they were covered in keratine, so in reality they were larger than the skeleton skull. The frill made it more difficult for a predator to attack the neck of the animal. Apart from that it also makes the animal look bigger (like a frilled lizard) to intimidate a rival or predator. If you look at buffalo's, the horns are used against each other and against predators as well. The ball joint in the neck of a ceratopsian made it very maneuverable, being able to put its head facing a rival or predator. Like they were build for combat.

Triceratops lived in herds like others. A relatively recent discovery by a team of the Dutch museum Naturalis found a herd of 5 Triceratops skeletons together.

" in theory " is right! more fantasy than anything else - no soft tissue survives, so this is utterly conjecture

Tricep Ceratops.

Again, *use the correct terminology* : Brain mass to body mass ratio is called the *'encephalization quotient'* , a rough measure of intelligence.

Dude: The 'shell' on the belly of cheloniids is called a 'PLASTRON'. Please try and use the correct terms.

Did you just say 'sajinal' crest?

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.

Dracorex was a juvenile pachycephalosaurus

We actually cant really tell the difference of sex in all mammals. Look up studies of Neanderthals when found in numbers very very rarely can we tell their sex

I sped it up to 2x speed and he sounds even more like Ben Shapiro 😂😂😂😂

One of the best rock jams i ever worked on. The good old days.

Damn, i remember working on this with you. Really miss our sessions.

We also attack each other's faces, but we punch instead of biting.

Lovely lecture. But I have to tell you I disagree eith calling birds dinosaurs. If that is true, then why not call us Therapsids? You have to draw the line somewhere and the modern bird is so far structurally removed from dinosaurs that I can't accept calling them the same.

Zuni was early Jurassic?

Evolution is such a joke I can’t believe I fell for this when I was in school. There’s no proof of evolution at all, and all the layers that are millions of years old, that’s all sediment from the flood. That’s why you get sea shells and other sea fossils mixed with dinosaur bones, it wasn’t a asteroid or the climate it was the flood that wiped them out. Easy answer just look it up for yourself instead of listening to college professors just saying

This is the best video I have ever seen in my whole entire life - thank you!

Tyranosaurids ruled the northern hempishere and the abelisaurids rules the southern hempishere. Here in australia we had the majungasaurus. From my knowledge, dont hurt me Great videos :)

Adaptation. Not the same as one species transforming, or "evolving" into, another species of animal. Still looking for that video.

I LOVE TRICERATOPS🥰🥰🥰🤩🥰🥰🥰

I know how stupid this sounds but I've looked at a Lot of places/sites! Can someone tell me where I can get a photo, diagram or even a sketch, of how the spinal Cord gets past that Ball and Socket Neck on that Organic Carbon Based Battering Ram.- Cycads Appalachia I've heard still has a Butt-load of carbon sink if anybody should ever need it.

Given the "bites on 50% of large (but not yet mature)" rexes, and about 60% of adult-sized rexes, could that be a sex marker? Certainly not as sure as some others, but it seems likely fewer females were biting each other in the face competing for males...

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?

34:00 I always thought plankton was turned into oil and plantlife turned into coal.

Whatever that breath noise or scooting noise is that keeps happening once in a while, it makes me picture him with a live triceratops is with him for this lecture

Who wrote "About 2 meeters long" in the text concerning Psittacosaurus? If this is about academic accuracy, you will have to do better than that. It should be "2 meters".

Thorough overview. One thing around 1:11 tho. If you have ONE dinosaur cell - intact - you can trigger this cell into almost all other type of cell we have. There is still problems, but the argument that 'they have only create ONE cell yet' so therefore there's a long way to go, gives a wrong picture. We don't need one of each cell type. The problem I see is that that cells can only divert back to earlier stemcell/types if the first generated cell is close to being complete. Error correction in the cell can only do so much..

Tyranosaurus rex did not weight 70 nor even 17 tons

Already at the 13 minute time, and this is an extremely well done presentation and lecture. Some notes: Meters and pounds, eh? Stick with metric and everyone will be better off, eh? Entogeny - not with that hard "g" but rather the sound of "j". Just look it up, it's there in Google translate or in any other dictionary, a major word here. But it's going to be outstanding! Subscribed for more!

considering his stride was 10 foot a slow walk would be unreal fast

i can totally kick t Rex's ass in rock , paper scissors

Very cool love the shell detailing

How do scientists determine an early trex vs a later version? Ive always wondered how they determine ages of ancient fossils

I LOVE CERATOPSIANS!!!!!!!!!!! I'm so glad you agree to love the Styracosaurus! It is my #1 FAVORITE dinosaur! Thank you for giving them some love!!!!!!!!!! Also, do you support evidence they might have sported quills on their tail and that they might've been omnivores?

Is the Torosaurus skull so much lighter built than the triceratops skull? Because i read that the largest skull is from Torosaurus (even larger than Big John´s skull) but it´s estimated smaller and lighter than triceratops. Otherwise it wouldn´t make much sens for me... no?!

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.

only 45lb? shouldn't it be 450lb? seems impossible for a 2m long dinosaur.

Lol. KZfaq put a climate change note on the video. Can't have people speaking against the regime on this platform. Must conform to narrative.

Megalodon never swam in the western interior seaway.

I am suddenly frozen in place by not caring very much

I have a theory about brontosauruses. Brontosauruses are very thin at one end, getting much thicker in the middle, and getting thin again at the opposite end. This is my theory

I find it amazing that they were around for 140 million years, to have such a stable atmosphere for that long Earth was truely a paradise then

“Sauropods can grow up to 73 feet long”??? That’s a rather low estimate there.

I'm not buying what you're selling. So much projecting from a few bones. Lots of fakery in this field.

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.

Now i have to go learn things about ducks im betting i didnt wanna know!😂

I think you meant to say that the Grand Canyon is 6,000 feet deep, and not 600.
