10 STRANGEST Prehistoric Sharks That Ever Lived! 

I just needed to know more about the helicopren shark.

Sharks are my favorite creatures to learn about. I wish I could go back in time and check out these prehistoric sharks.

7:11 looks similar to the prehistoric frilled shark. Cladoselache relative 🤔

For #10, we are told the hybodus preyed on 'whales'. We're also told that they went extinct 66 million years ago. 66 million years ago, whales had not yet evolved.

Nice video but some of the information is presented in a misleading way. Primarily the part where it is confusing as to whether or not you meant that electro sensory was a skill exclusive to the Scapanorhuynhus, when it is in fact a common trait shared between At least most sharks if not all.

I love how accurate your facts are. My only problem is that what ur talking about doesn't always match the pictures

10:01 This narrator is playing ARK, she thought we wouldn't notice, but we did. Seriously though nice use of ARK footage of the Megalodon XD

I think that nearly every "monster" is still alive, somewhere

Was it a different shark or was it cladoselache that was discovered recently to be alive and not extinct

Lol! I LUV the random picture to keep us entertained!

Oh yes, sharks. My absolute favourite, and absolutely not terryfing whatsoever

My response to this whole thing: NOPE NOPE NOPEEEE

btw here are some things to take note of 1. The helicoprion is not considered a shark. it is a eugeneodont fish looking shark but actually isn't! 2. the edestus also isn't a shark. it is considered as a holocephalian fish that lived back then. 3. Otodus is a family of sharks. Not just a shark. The Megalodon is known as the O. Megalodon because it was part with the Otodus family of sharks. Also goes with O. Obliquus, O. Sokolovi, O. Chubutensis etc. Hope this helps!

Hi i must thank u, ur videos have Spark inspiration , for my next book I'm going to be working on :) please keep making more videos

HungryShark evolution has updated? The graphics are so amazing and realistic! I can’t wait to play it when I get home!

4:58 was anyone else wondering this is where the old Cartoon Network show the snorks came from lol 😂

Brilliant brilliant video I love sharks thanks Katrina

Thanks for the information and you guys are awesome

Is there not a video that focuses on the helicopren shark

This is the coolest things I've ever seen

They're nasty yet fascinating.

Ya i love your videos I look forward to seeing them every weekend mornings keep up the good work you're doing great ☺🙂

Some of these sharks are not just strange, but also creepy looking to me. O.O Anyway, nice video!

That Ark Survival footage at 9:37 thoooo 😂😂😂😂

Nice Video!,it really chilled down my spine😂

8:28 my best shark on hungryshark evolution

what background song is this? it really sets the mood when watching these good vids

1 like 1 prayer for none to be alive. Only 5 percent of the ocean has been discovered.

7:04 the face you make when you first time defeat a boss-battle no dying

Your the best,this help me in science and my homework

Great video. I love your channel. All your topics are very interesting. Thank you.

Very fascinating !! Nothing "fishy"about these Interesting facts!!Good work, Katrina!!🐬🐬🐬

My top 10 strangest prehistoric sharks. Bobbodus, parahelicoprion, sarcoprion, caseodus, fadenia, romerodus, listracanthus, edestus, delphyodontos and helicoprion

Very intresting! keep going.

The helicorprian is actually not a shark and is related.

The helocripoin is a shark who stabbed it's pray by letting a circle of teeth come out of a role

Loved the informational video I learned a lot of stuff

The first one feels like a filling... =/ I was thinking about Megalodon but the title called for Strangest then I said meh... Megalodon is just a big big version of GW.... and i was thinking the Helicoprion would be no.1. But still great job Katrina, it is not easy to produce high quality interesting videos on daily basis. Take care!

1:09 Whales weren't around at that time. The more accurate one is "Small Marine Reptiles"

So amazing

wow i never seen those before,i heard of the helicoptrian!

You say it like “mausosaur” lol

0:00, what's that from?

Awesome vid guys love your Channel

I watched a prehistoric shark tv show year ago that had a funny looking shark in it and we couldn’t remember the name of it so we always just called it the “chimney head shark” 😂 finally today after years of not knowing the real name of the shark I find out it’s called a stethacanthus. Thanks!

don't forget to add eagle shark in there, they're really weird

Love learning about earth and her children. Thank you for this wonderful video. Be well.

Xenocanthus was my favorite

Otodus? sounds like a Roman gladiator.

This is a very good video

I love sharks. They are the coolest animals ever especially their very very sharp teeth. For my love of sharks I think it's awesome there are many acient sharks. I love sharks so much.

8:28-9:26 what you came to see. NOT clickbait.

Is there a dunkleostus

Hello i love your chanll

Aww the falcatus shark looked cute

Helicoprion... Isn't... A.... SHARK!!!!!!!!!!!!!!!!!!!! That's not even how the saw looks!

The “scapanorhuynchis” is actually a goblin shark and is not exstinct

i hate it when people stretch their vids to 10 minutes for the ad rolls.

I love the prehistoric SHRKS❤❤🦈

Wow, wha6 a fantastic and also amazing shark 😂😂

How do you know all this?!

for the ppl who saw the thumbnail it’s number two

the thing at 1:19 is a Mola Mola and the Mola Mola is A VERY BIG BOI

Is there a xenomorph shark XD

Those are some very strange sharks

I Like Prehistoric Under Water Dinos

I’m here because of the comment on L’s video. Running them likes up Fam

Stethacanthus is like a swimming coral reef

6:06 What is that thing on the right? Its like moving in circles. Looks pretty interesting.

the number 9 most stranges shark is actually a goblon shark 😑😑😑

Imagine thinking a helicoprion was a shark.

THIs is cool I love it.

Best work yet you guys

The helicotor right? Oh I knew it!

Reminds me of street sharks

I love your channel keep it up👍🏻

Do we know what the first shark to appeal was. Second if you keep coming up with videos like this I still keep watching

My favourite shark is Megaladon

People: He’s ten he probably watching cartoons Me when 10: Go to youtube and watch facts of extinct animals

Don,t forget the Megaladon

The otodus footage is literally gameplay from ark survival evolved

LMAO at 10:05 they are using footage from ARK: Survival Evovled :P

The scap whatever is just a goblin shark and then they made up the thing to find prey

so number 8 you say had scales like most other fish but no idea what it looked like? how can some one first, know it had scales and not know what it looks like AND only find its fossilized teeth? things aren't adding up for me on number 8 🤔

For once a video of prehistoric sharks is real n not fake

That helicorprion is creepy ass helll

When almost half of all the animals presented aren't even sharks at all.

The stethacanthus uses the spikes on their dorsal fin to poison its prey

Cladoselache is still alive a person on japan found one a couple of years ago

Whale shark gets longer than Otodus

Fun fact: each shark info is a minute long! Except clodasache.

so the xenacanthus can break a turtle shell

What's weird is that the Bible says that Adam named all these beasts.... How ?

Stethacanthus is in hungry shark world

Nice video

2:02 well hello there

I think you forgot about the dunkleosteus thats a shark right??

Name of music?

1:09 If this specie died out 66 million years ago it couldn't have eaten any whales.

a lot of information nice
