[@TheSandwhichman108]

Can we just give some mad respect to mister man? He kept getting deformed and put in various situations and he just played along without complaints.

i keep watching your video on top 5 extinct sharks, im so happy you made a new one about the ctenacanths

[@trilobite3120]

Isn't that one also on ctenacanths?

Man, that Eyewitness theme hits every time. Pure nostalgia.

[@Jyiber]

I still am awed by the simple fact that sharks are older than trees. Let me reiterate; sharks were murdering things successfully millions of years before the first tree evolved.

Yarr that be the scurviest sea dog to ever swim the Seven Seas!

[@hoibsh21]

I wonder if the spines were venomous.

[@adventureswithdan84]

It seems to me that weird sharks are either prehistoric species or living down the deepest depths of the ocean.

[@kieran_xcvi6636]

That’s because the sharks in the deep ocean are very old they’ve had no reason to really evolve a whole lot

[@bruh-vj1yg]

10:30 i severely doubt that Dracopristis could reach 1206 cm, that is 12 meters, making it comparable to a large whale shark

[@memesimp3216]

Yeah the animal itself was around 6 feet or so, that might just be a mistake

[@justplainpsychotic]

Might be a typo, supposed to be 206cm? That would be 81 inches which is just over 6ft.

[@trilobite3120]

@@justplainpsychotic That is what he said.

[@the_blue_jay_raptor]

That would be cool as hell though

[@marcusmulethaler5367]

That shark with the lower jaw that looks like a circular saw blade, I’m always going to wonder how that’s supposed to be practical for the shark? Or why its like that, how its used, etc. Its just so weird.

[@patreekotime4578]

It's not terribly weird if you think about how sharks grow teeth... they actually always grow teeth in a spiral! New teeth are constantly just behind the old teeth ready to take thier place. What is weird about Helicoprion is that it only has a single set of teeth in the lower jaw as opposed to dozens.... and that it didn't shed it's old teeth, it kept them, and they spiralled around down back into the jaw. For a modern shark with unusual jaws, check out the Port Jackson shark... it evolved to eat mollusks.

Yup

@@EDGEscience I hope at some point we get a video on Don Juan or El weirdo at some point.

[@EDGEscience]

I want to but there isn't much info because it's not yet described.

[@trilobite3120]

@@EDGEscience Indeed. I hope they get described soon. I appreciate the attention you give to Carboniferous cartilaginous fish. They're probably one of my favourite "group" of prehistoric animals next to placoderms and Ordovician cephalopods.

[@trilobite3120]

​​@@EDGEsciencePerhaps a short form video detailing the little info we do have, to build up 'hype' I suppose.

[@Darth-Nihilus1]

I know in other layers around Allegheny and Beaver county you can find sharks but does anyone know if I could find sharks in Ames limestone and Grafton? I live in Turtle Creek Pennsylvania where the top of the hills is Pittsburgh coal Monongahela and the bottom of the valley is Pittsburgh red bed Glenshaw formation. I have found everything from plants to amphibian foot prints and insect fossils but the layer of Ames is 2 foot thick and I have only found shells and crinoids in that limestone
