Hello everybody, I hope you all are doing well. My Patreon page is finally up and if you would like to help support me and the channel, you can choose to do so and get some neat rewards in return! www.patreon.com/Natures_Compendium For this video I had a friend do the narration for me so I could spend more time animating. Rest assured I will continue to narrate the majority of the videos but in the near future I hope to have additional guests narrate videos for me as well. The subject of the video was voted on by a KZbin community poll and I hope you all enjoy it!

Ah, Dunkles. One of my favorite beasties. I grew up in Colorado, and the Denver Museum of Nature and Science was one of my favorite places. At the end of the Prehistoric Life exhibit, they had (probably still have) a Dunkleosteus skull (weirdly placed, considering the sort of "timeline" organization of the exhibit, putting Dunkles after the Ice Age, but whatever). That skull always left such a strong impression on me, I never forgot it.

I still see no evidence for dunk being small, I hope this “tiny dunk” trend fades away like feathered Rex, it’s ridiculous, dunk needed it’s size to be an apex predator in climates with creatures like Endoceras.

[@Mr.Shikishima]

​@@thesalmonguy3342 but the method of getting the size does makes sense tho

[@vault_dwelIer]

​@@thesalmonguy3342 Endoceras was an Ordovician animal you absolute donkey. Prior to the new findings, the Arthrodire Placoderms were the biggest creatures of the Devonian, and they dwarfed everything else. Now, they are still the biggest, but they don't comically dwarf the rest of the seas. A smaller Dunkleosteus makes much more sense for the fauna that lived at the time.

[@oculusangelicus8978]

Dunkleosteus is my favorite swimming fossil, ever since I saw the armored plates of it's head in Royal Tyrell museum here in Alberta, Canada, I have always wanted to learn more about it and how it lived it's life. I'm a fisherman and I have to say that it would take one hell of a leader to secure a catch like that! The thing must have weighed in at around 500+ pounds for an average specimen if my estimates are correct but who knows how big these things actually got? It certainly would have had a powerful presence in the Devonian Oceans If it wasn't the Largest of creatures to swim in the Devonian Oceans. It is simply a scary fish that out-intimidates the Shark! Although it's smaller than the Largest of the Sharks, like Megalodon, it has Armored plates that would make it a very serious foe to deal with regardless of size. I wish I could see what it truly looked like and how big they actually got! the Fossil record shows so many amazing creatures and I would love to have seen them all, and to be able to draw them like the early scientists did in the nineteenth and early twentieth centuries did! The Natural world is so awe-inspiring and so full of mystery!

[@AspieDino98]

@@NaturesCompendium I’d take it with a pinch of salt, TBH; because we only know of its head armour, what the rest of Dunkleosteus’ body looked like is still up in the air, at least as far as I’m concerned. Don’t get me wrong; I’m okay with either outcome, but until we can find the rest of Dunkleosteus’ body (which doesn’t seem likely), educated guesses on how big it was in life are the best we can do. The idea that it had a short body because it had a short head is a very general idea. There are exceptions to this rule, like Xiphactinus, for example
