Helicoprion | The Permian CHAINSAW MAN FISH 

Hello everybody, I hope you all are doing well. This video was long overdue and a lot of unintended circumstances factored into the delay. Nevertheless, I did my best to deliver and I hope you all enjoy the video! If you would like to help support me and the channel, you can choose to do so on Patreon and get some neat rewards in return! www.patreon.com/Natures_Compendium For this video I once again had my friend Jason 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. This will also be the last animation I make for the year and the last aquatic animal I'll be covering for a long time. Stay tune for next year as I will be tackling mostly Dinosaurs!

The Permian had the coolest creatures on land and sea.

Some suggested reconstructions of Helicoprion suggest a more rotary sawing motion than merely up & down. Eg: • Open mouth wide. • Push jaw slightly forward (much like modern sharks). • Pull the jaw back towards the throat, creating a rotational sawing motion. • Simultaneously closing the mouth, creating suction to aid with swallowing. This would have given a greater cuttıng length - putting more of the teeth in contact with the prey - than a mere up & down motion. [ Kind of like a Sliding Mitre Saw vs a Drop Saw. (Only inverted.) ] It's also worth noting that the structure of the teeth in the spiral changed subtly over the animal's lifetime. The smaller 20mm teeth in the beginning/center of the whorl had a thinner enameloid coating (making them only suitable for soft-bodied squid), while the later, much larger 100mm (asymetrical, outer edge curved/inner edge straight) teeth were tough enough to carve up both fish & (potentially) even hard-shelled ammonites. They were a very successful clade, with fossil teeth whorls found over a 20 million year period, and in areas as diverse as the United States, Norway, Russia, Kazakhstan, China, Japan & Australia.

The narration of these videos is so soothing! Not only do I learn something new, but I feel relaxed in the process! Also, I LOVE the art and animations of the creatures!

Wonderful! This animal is so under-represented! I would love it if you did a series starting at earths beginning till now

I personally enjoyed Edestus being featured! Awesome video as always!

What if shark, but industrial saw? - mother nature

The Paleozoic era is wild!

I love this animation,and the history of Helicoprion was pretty great and I wish yall a great day

Great as per usual! You have a nice voice for narrating those btw

I love these videos, they are informative and entertaining at same time =)

Helicoprion on my opinion is one of unique fish i've seen before

Great narration, pacing, and animation!

Denji: its chainsaw maning time Some permian fish: Hold my chainsaw

You animations make a day better and also its very accurate good job Mate you made an awesome video helicoprion was truly a interesting animal and your video makes it cool thank you for your great work Mate :-)

That voice was so relaxing and this video was very informative and the art was very pleasing to the eye. 10/10

Great job on this video! Love the information presented on this shark, a Paleozoic one is always cool.

Awsome Video I think the First theorys were pretty funny Looking but It's hard to belive that such a jaw structure would have more effective than the ones of modern sharks As Always the animal Design and Animations are awsome!

Yesss!!!! Been waiting for this

Amazing work my friend

Man, sharks sure went through some weird forms as time went on. Shame this guy hasn't been given the time to shine in media that it deserves. Fingers crossed for either Prehistoric Kingdom or some big documentary appearance at some point!

the king has returned

Ngl, I'm getting *MAJOR* Dr. Wu from Jurassic World Evolution vibes from the narrator here!

Hell yeah new vid

I’ve been wanting you to make a helicoprion video one of the most bizarre and most changed fossils in the record from the buzz saw being on the fin,tail and even the stomach until it was put in the lower jaw wich is the modern impression

This was great!

Awesome video

awesome video

Never realised they were so big! I always thought they were around the size of small sharks alive today, not gigantic predators

Awesome

can you give the source for the 12m eugeneodontid? i'd really want to know more about it since i believed dunkleosteus was the largest the paleozoic sea had!

What were some of the other marine creatures shown in the video?

Helicorpion was a lot bigger than I thought.

The helicrion is my favourite fish In the world

I hope for this creature to be a plush , video game characters and cartoon

Dimetrodon wasn’t a reptile but amazing video Helicoprion is so cool

Does anyone have a link for the CT scans?

Still calling the Buzzsaw shark though!

Finally

0:20 I guess Simon Stålenhag was your inspiration with this one!

I'ma subscribe

nice :)

Noice!

What was the fish at 4:55 ?

Got the Saw Jaw with the Knife Life

It might not needed to hunt fish. There were probably very large specimen of Squid avaidable I suppose?

So when the Heli loses one of its teeth, does it rotate its jaw to expand the hidden teeth, or does new teeth grow from the bottom? This sounds like a dumb question, but I’m curious!

Can you please add subtitles to the video?

Bro just didnt know how teeth worked yet

But did it really look like a shark?

3:51 squids do not have red blood they actually have blue blood that’s one inaccuracy right there.

Xiphactinus đi ạ 😘💞💞💞💞💞😘

Buzz saw shark

Which is yhe closest relative of the helicoprion🤔?

So I know it’s not a real shark and all but screw it he good enough

Really cool for killing, but seems quite inefficient for eating.

The current theory of how the spiral teeth fit in a shark's mouth seems rather unlikely... how could it eat with the spiral in the way? Looks wrong...

BEEFIS OF PHENOMENAL SIZE

can you make a video about dimetrodon?

i think the helicoprion is a giant predator

Helicoprion mesure 10 m

Hey dude where’s your Jurassic word evolution videos

Indominus rex

This shark is só coool

Dimetrodon is not a reptile

#squidgame

Good one but you hurt my feelings with dimetrodon being a reptile

MORE LIKE HELICOPTER

0:23 "Reptile" 💀

Dimetrodon are not reptiles

You should make a video on tyrannosaurus Rex or your channel channel not usefull so please make a video in T Rex
