Dunkleosteus Deconstructed ~ with RUSSELL ENGELMAN

[@longcastle4863]

Amazing fossils. Mind blowing there wasn’t more interest in them until now. And great exciting research. Must have been a few “holy sh!t this is good!” moments there.

[@anndriggers6660]

I think I found one of those things eroding out of the ground in my backyard in Austin, Texas. It looks just like the lower jaw of this thing. Symmetrical triangular teeth on each side. It appears to be just the lower jaw, but it's so heavy I can't pick it up... really scary looking! I knew that it had to have been a living saying at 1 time or another because it is so symmetrical. Rocks don't form like that.

hello and well done on the interview ! 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

[@JLomboCrop]

This is such an incredible interview. Dunkleosteus was my favorite growing up and, much like was said in the video, all I really knew about it was "it's a big scary armored fish guillotine". The research on how it's jaw worked and the research brought up here is really incredible. Furthermore, hearing about the experience of the Mr. Engelman was fascinating. Deep down, kid me still imagines it's huge and fights Megolodons and such though lol

[@jamestodd2323]

Incredible research. Seems to happen all to often in the scientific community that assumptions are made and decades ago past without any actual thorough data crunching. Thank you Russell ...and Evolution Soup.. for this.

[@wenthulk8439]

Very interesting

[@petrairene]

What makes huge sizes for Dunkleosteus unlikely is the availability of prey at the time. How and why would it have grown so big, with that enormous bite strength? Where is the prey species that encourages evolution of an 8 meter predator?

[@eljanrimsa5843]

I'm not sure I can follow you. If Dunkleosteus can grow to 4 m why can't it grow to 8 m? The biggest predatory sharks today grow to similar sizes but their prey species are much smaller.

[@petrairene]

@@eljanrimsa5843 It can. But only if there is prey that makes it favourable to be larger because that larger body needs a lot more en energy to sustain. A tiger is the size it is, because that size is ideal for the prey it hunts and the amount of energy it gains from it. If there is larger sized prey available the predators hunting it is getting larger. So predator size is, among other factors always closely tied to the size and availability of prey.

[@eljanrimsa5843]

@@petrairene I hear you, but I don't believe it. This makes sense for land animals, especially ambush hunters, but predatory fish are much larger than their prey on average.

[@petrairene]

@@eljanrimsa5843 Predatory fish are on average much larger than their prey because they have to swallow it whole. But that is not the case for this one, it can easily take bites out of larger prey. Why does it have this huge bite force if there is zero need for it because it eats smaller fish that it can swallow whole?

[@bennettfender9927]

You do realize Titanichthys is a thing right?

[@leezebede4469]

Is the reason that people aren't doing studies on Dunkleosteus because there isn't many fossil to study? Or because its just not hip to study Dunkleosteus

Great, great vid🏆Thanks, guys💜🇫🇮🥂

27:45 Holy crap! 😱

[@kerbygator]

You would die as soon as you see one coming at you, from a heart attack.

[@LanceHall]

Nice to see someone finally apply proper analysis to this animal.

[@LuisAldamiz]

Is this a remastering? I'm pretty sure I watched this before like a month ago...

[@EvolutionSoup]

Nope, brand new -- you might be thinking of when Russell appeared on the Skeleton Crew KZbin show?

[@LuisAldamiz]

@@EvolutionSoup - Then it is the most total deja vú ever, because I'm sure it was this very same story: dunkleosteous has not been as much researched as people imagine, something about covid, tuna-like, etc. I wonder if he has given a similar (but surely not strictly identical) interview in some other channel I follow. Seems to me like the only reasonable explanation, because deja vús are not that precise and extense. Well, whatever, thanks for replying.

[@lucasb1324]

I don't understand where I can find your goods. Red double shop? Other than that, I like your channel. 👍

[@EvolutionSoup]

Hi- there is a link to the redbubble shop in the description if you scroll down. :-)

[@DogFoxHybrid]

I'm happy that they're saying the name right.

[@AgroAcro]

I actually am very glad it was downsized. It is one of my favorite animals now and I only started looking into it because so many people were talking about the downsize.

[@Psalm1101]

Reminds me of a nasty alligator anapping turtle

[@handledav]

tuna are not rotund

[@handledav]

no, that's not why the placoderms went extinct.

[@jamestodd2323]

If you really had some insight you'd present it, rather than just saying 'nuh-uh!'

[@theaviandinosaur2.0]

Actually first

[@chriswerb7482]

The "carbon capture by trees" phenomenon was much worse than explained as the organisms that could break down plant matter to release the carbon in the decaying trees would not exist for many millions of years, leading to the build up of what eventually became coal seams.

[@vinny184]

the coal seems came from the forests repeatedly flooding with seawater, which buried the organic matter. Then the lands dried up again, forests regrew and were then flooded again.

[@vinny184]

There were definitely already fungi and bacteria that could break down plant matter.

[@Psalm1101]

As a paleotologist we dont consider mutation as a mover towards evolution this is due to probsbility mimbers from physicst mathmatics scientist on this sibject. Darwinism has problems today concering rhis topic.

[@stefanlaskowski6660]

Only Creationists label evolutionary biology "Darwinism."

[@Raydensheraj]

Darwinism is used in numerous books by numerous individuals like Dawkins, Ruse, Forty etc...all it means is of course "evolution by natural selection." You can tell through the guy you answered is full of poop. He isn't a paleontologists, he doesn't know what he is talking about...and I found multiple mistakes in his grammar...so yes.... probably a creationist 😂
