- "In and Out of Africa-the Horned Giants That Ate Our Ancestors"
Lecture by Chris Brochu, UI associate professor of geoscience. Recorded November 2012 at the University of Iowa Museum's Biosphere Discovery Hub.
The Department of Geoscience is a unit of the UI College of Liberal Arts and Sciences. Brochu specializes in vertebrate paleontology and phylogenetics, which are evolutionary relationships between organisms. His research combines the study of modern animals and the fossil record to demonstrate how evolutionary relationships can be determined through time. He is an expert in crocodiles and travels the world to research specimens in museum collections.

No chance to pay for college so thank God for these universities and colleges putting lectures up on TH-cam. It's what I live for, anything that has to do with life how it came to be where it's at and where it's going
Your the perfect person for a tuition to attend any school cause you have the drive to learn!
@@sforza209 I would love that!! You would think that a government would want smarter ppl, to help innovate the future.
I hope I’m not the only person that thinks the word “crocodyliform” is freakn awesome lol
shaped like a crock in australian..
This guy's enthusiasm is infectious. You can tell he really loves what he's doing. 👍
I love how much this guy loves this topic!
Very entertaining presentation , good story telling and good observations. Thanks, Christopher Brochu.
Earlier in the talk I thought of the crocodile remains on Aldabra near the upsidedown jellyfish pool also near to where the sacred ibris hung out and the large fruit bats hung down from the bushes. Did he know about it? When you mentioned Aldabra I nearly jumped off my seat. Thanks for that mention brought back memories of 36 years ago. Thanks for the presentation I enjoyed it.
Brilliant guy! Looks like the audience was really tired or didn't get his jokes, hahah. Very fascinating topic, glad to see people out there educating others on the more obscure, but nonetheless wonderful topics.
Interesting but NOT funny. He should give up on comedy he's rubbish at it.
Bo McGillacutty Looks like someone should be looking up CarrotTop videos and not science lectures.
I laughed out loud a few times. The guy’s witty. The audience just wasn’t very responsive for whatever reason. It happens.
he specialises in the typology of crocodiles and their kin, if he makes some jokes i'm glad of them, and not expecting him to be devoting too much time on developing the skill.
Agree, this guy is fantastic.
This is exactly how someone comes across who is truly passionate about a certain topic & tries to share that enthusiasm with others who just don’t have the same basic understanding. It goes over people’s heads but it’s fascinating.
A very interesting talk, I enjoyed it and thank you.
I loved this talk, thanks for sharing!!!
A lot of hard work. bravo
About time they make a Dino Zord of one... Seeing how Power Rangers are the pinnacle of recognition that prehistoric creatures can reach
Very interesting talk. Thanks for sharing.
Bit of a clickbait title, but it was interesting if a bit unstructured.
Also the guy gets kind of obnoxious as soon as he starts talking about anything besides crocs.
Why not include the questions?
Fantastic!!!!
I don't do primates, I do things that ATE them.
Awesome guy! Does anyone know of any other lectures of his here on TH-cam? Search yielded nothing.
Dvich Search "crocodiles evolution myth" shows up in a lecture for east Tennessee's channel
If you want fossils I suggest the royal tyrell museum channel. They have lots of lectures mostly on dinosaurs.
the camera work is killing me. stop zooming in and out on the guy and panning over just cause he switches the leg he standing on. just frame the screen with him in it and let him walk back and forth. its super distracting when trying to look at the pictures and it pans away and zooms in on the guy. other than that it was interesting
A brilliant man great information although very scattered and not well organized due to how he had the presentation put together I felt like I was having trouble Absorbing the information
Very cool. 1 thing I never understand is why does everything have to cross land bridges, swim or fly across oceans to be in an area. I'm pretty sure that rarely happened.
For an 82 cm skull to yield a 27 ft croc would require a 10::1 ratio, somewhat more than a 20% increase over the stated norm...still, loved the talk!
yeah, but it's cool ( cool = not scientifically valid ) and he defined cool with the vignette on the 'aquatic ape' nonsense. Keep up dude !
The largest accurately measured male, shot near Mwanza, Tanzania, measured 6.45 m (21 ft 2 in) and weighed about 1,090 kg (2,400 lb) not 18 ft
LOLONG PHILIPPINES 20'3'' IN 2013
This might be more interesting once they find out the things they haven't figured out yet.
20'3'' NAMED LOLONG IN PHILIPPINES ..
I laughed at all of his jokes, wtf is wrong with the audience? Hello!!! Wake up, wake up wake up!!!
They were as lively as a time share presentation audience
I’m so trying to understand & I think I do for the most part, but I have so many questions. I feel like I need a dictionary to look up half these words & a children’s dictionary for the words in those definitions.
Need to spend more time zoomed in on the screen. Except when the presenter is pointing to s own skull really don't need to see the lecturer
Did that one fellow have the upturned nose so he could stick out of the water and still remain concealed?
Nice Ngorogoro crater story. I guess that there some things Hyenas won't eat :)
there aren't bottom feeders I guess.
Study the crocodiles in Agusan marsh of the PHILIPPINES. The crocs group there are the biggest in the planet.
We don't know why so much bigger than Africans or Australian crocs.
Are they still alive?
Huh, maybe purusaurus predated like flounders, sucking in passing fish.
Fred Durst sitting front row. lol.
How the hell did they cross the Atlantic ocean?
that's what I'm wondering
Depending on when we're talking about there may not have been much of an Atlantic Ocean to speak of. Don't forget, the Earth didn't always look the way it does now with continents where they are now.
Mid Atlantic Ridge creates new seabed and so the Atlantic isn't that old geologically speaking and thus was much smaller when they crossed. I think that movement/ seabed generation is just a few cm per year. If you look at South America and Africa the coastlines were once joined and also Scotland was joined to North America. A quick calculation which may not be accurate is that 6 million years ago the distance was 150km less or circa 100 miles...
They swim...I think I read that crocodiles are found swimming in the ocean between Australia up through the islands and even around south east Asia.
Tough crowd
In a way, he's a crocodile hunter.
they survived the asteroid hit
Except for the Yucatan Crocs of course.
I think it's time we stopped taking this lying down and darned well avenged our ancestors. Let's teach those extinct giant horned crocodiles a lesson! Who's with me?!
edit: Apparently nobody lol
It's even funnier that no one replied=)
We're with ya, man! Lead the charge!
@@Doxymeister The lizard people hear about this we're gona be history bro............don't do it bro...........don't.
@@mazzolaro1 LOL...
this is a perfect example of the problem...if l played along...ld feel dishonest...yeesh...
Crocodylus thorbjarnarsoni is just a big nile crocodile, humans will see big shows skeleton compare it to a normal human and say they are two different species
?
bloatedman I agree. ????
Looked at your channel, ok you are not a native English speaker. Though what ever you were trying to say is really obscure.
@@DAYBROK3 I'm just guessing here but i believe "big show" is referring to the WWE wrestler. He's pretty damn big.
Would be more interesting if there'd been better close ups of the images he was presenting. Guess you just had to be there to appreciate it..
alligators in iowa, well maybe not extint and still preading, and why whywhy bring back sabortooth tigers...ick, their eatinghabilts...they eat everything
The long nose evolved in a creature that needed to keep prey at a distance from its eyes as it held them underwater.
As long as they ate them AFTER the subsequent ancestors were viable, it all would work out. Otherwise, you wouldn’t be here to watch the video.
Great presentation. Horrible filming. Really bad. Camera-person: keep the dang slides on frame. Don't wander around with he presenter. He's not as important as the data on the screen, which you constantly abandoned to follow him around as he talked, waved his arms and POINTED AT THE SCREEN WE COULD NOT SEE! What was it that made you cue on his face and ignore the slide presentation? This was a fine lecture with horrifically frustrating camera coverage.
@35:25 Dr. Brochu says the 'aquatic ape' hypothesis is a "cool" idea with "absolutely no evidence for it." th-cam.com/video/gwPoM7lGYHw/w-d-xo.html
it lived in alamosa 65 thousand years ago, in whats the blanca wetlands. funny thing, they have alligators just down the road.
The audience is boring.
秦始皇Qin ShiHuang So true
U
I’ve never seen someone fail at humor so many times in one speech that would’ve been just fine without any humor at all! I actually started to feel bad for the guy towards the end when he said something he obviously thought was hilarious and looked at the audience to share a good laugh only to hear crickets and awkward silence!
great, hyenas bad
what a boring audience..
Definitely!
Clearly this guy didn't have the help of others when he put together this presentation, or they would've pointed out his poor sense of humor. Don't get me wrong, the information itself was wonderful and interesting, but man, his jokes just made me face-palm. Know your strengths man, humor isn't one of them.
His dismissal of the aquatic ape theory really proves what he said about knowing nothing about primates. Suggest he give elaine Morgan a listen. Read her scars of evolution . Think you. Would have a 50 50 chance of beleaving8
