This video won't load at all and that's...a shame, I was really enjoying the dinosaur lectures playlist and the playlist won't skip this video (because it isn't a deleted video) so it just chokes on it and I have to manually skip it to continue on. Which is inideal for lots of reasons, the biggest of which is I can't access 44 minutes about theropods :(
In reply to both: You are absolutely correct Lars this is not a theropod skull, but it does have a great morphology which makes it easy to talk about form and function. I won't claim to be an expert on monitors and their relatives so if Lars has good reason to suspect this is a particular species I would not argue that point. Sorry about the confusion.
Great show man. At 16:30-ish you say Allo is a distant relation to Rex, but just a lot earlier. However I just watched a couple guys, doing other amazing presentations like your own, and I'm pretty sure they both said that Allosaur were not related to Rex, (other than being in the order of Therapod) and the clue is in the teeth, skull and the nose bridge bones. Rex's have a fused nasal bone, where all other apex-dino-predators have split. The skull of a rex is basically a block of bone, where the others are far lighter with far larger cavities, and the teeth of a Rex are more like bananas in their shape, rather than knives. They would use the weight of the skull to crush bone. .......edit..... all stuff you basically say later in the vid. Just curious if you meant, actual ancestor of Rex, or just meaning an earlier massive therapod carnivore?
Yes, mostly true (www2.palomar.edu/anthro/primate/color.htm). Many mammals retain nocturnal behaviors and so largely see a world in greyscale. What is unusual for humans is that we are trichromic. However many people are not, red-green color blindness is the most common form of color blindness in humans (~4% of the population).
I don’t have sound problems. I keep getting a “something went wrong” screen when I try to play it. I’ll try on on my desktop. Thanks very much for posting these. I’m enjoying them very much!
🙄 the last picture of the skeletons. The one on the bottom the vertebrae's don't match up right just look at them between the arm and the hip. Something's really wrong there it's like some of them need to go to the back and some of them need to go forward
I just popped my own brain, (I think that is what is supposed to happen btw). Could Tyrannosaurs have been the ultimate ecological machine? By having an age group for each category of prey. Social yes, to an extent. Almost a caste system, but familial at a same moment. It sounds stupid, I have spent an insane amount of time trying to figure out how efficient or even possible it would be for Tyrannosaur mothers to carry eggs and or infants. I don't know how two fingers would make it better or not...I can't imagine a better nest then beneath the most powerful jaws. Those arms HAD a purpose!!! What if each "level" of growth required a new job? type thing......That's all I was going for, basically, I'm to stupid to literate it properly. I spend to much time in "imagine" land.
Amazing sound quality.
lol
Audio cut out around 38:30.
Otherwise I want to enroll in this class badly
Excellent lectures, thanks so much !
i think this might need to be reuploaded. several people, myself included are unable to load it.

Xovvo I was having the same issue, I tried again today and the video worked, so I'd say try one more time. It's worth it.
For reasons unknown this video is bugged for me. It shows and time bomb and never loads. Sad, that. I was looking forward to it.
The skull at 12:47 is of a modern black-throated monitor lizard, not a theropod.
The speaker claims at 15:25 it _"is a Komodo dragon skull not a theropod."_ So who is right?

Carnotaurs were basically the real life version of Pacman.
Great show man.

Yeah, I think it's wrong too. Tyrannosaurs seem to be closer to birds than to carnosaurs like Allosaurus.
I can't hear you.
Humans see red - that is the unusual thing for mammals
Yes, mostly true (www2.palomar.edu/anthro/primate/color.htm). Many mammals retain nocturnal behaviors and so largely see a world in greyscale. What is unusual for humans is that we are trichromic. However many people are not, red-green color blindness is the most common form of color blindness in humans (~4% of the population).
Is this video broken?
No, the sound is too low. Turn it all the way up on your device. Sorry about that.
I don’t have sound problems. I keep getting a “something went wrong” screen when I try to play it. I’ll try on on my desktop. Thanks very much for posting these. I’m enjoying them very much!
I have the same problem. The video errors out. Regardless of device. Would really like to see it.
😡 Sound cutting out.

to quiet
volume suks
Yes it does, it was related to an imperfect mic, but I wanted to post these because I though people would like them in spite of that.
