- The oceans of the Cretaceous period were filled with amazing animals, including many sharks.

Why do sharks have all the weirdest teath
They don’t have any limbs to hold things down as they take a bite out of them.
They’ve been around for hundreds of millions of years so there’s probably been lots of time for them to diversify and get weird.
Its their only tool, so its the first thing that gets adapted to new prey. Just like beaks from birds are the first thing that changes.
They been around for a long time the bois were experimenting with shapes
Leatherback tutles are the weirdest, looks like a saarlaac pit from star wars.
I swear sharks and crocodilians have some of the weirdest yet fascinating history in my opinion.
Veeeery long evolutionary history allows for lots of radiation
100% agree! Crocodilians have a wild and fascinating evolutionary history. Like the one that basically tried to become a whale.
@@quynlanvuorensyrja5484or how some of them went full Mosasaur and went entirely marine. Or how some developed land capabilities and became land predators!
Looks almost like a Nurse Shark.
Theyre both pretty similar so it makes sense
that aint a nurse shark
that's a caregiver fish
@@legitusername-zl7to💀💀
Yeah a 14 meter one
This one's the neurosurgeon shark
The fact that there are entire groups of animals specifically evolved just to eat ammonites goes to show just how insane their numbers were. I like to think they were almost as widespread and rapidly multiplying as Lystrosaurus.
There were a lot of ammonites at the time. It should've been surprising that some species evolved to feed exclusively on them.
reminds me of some island where people kept finding fosils of marine predator species but no prey, eventually they determined that the area must have been utterly swamped with Squids (who don't often make fossils)
I wonder if it has any link to modern day stingrays. It seems like they filled a similar niche. Imagine a 14 meter stingray
Having similar features doesnt equal genetic similarity. Take convergent evolution.
would be rly cool if bayleen stemmed from this
Modern sharks:🙂
Prehistoric sharks:🫠
THEY LOOK LIKE ELEPHANT TEETH. 😮
Really cool animal!
Thats whats up!
Very cool! Personally, I can't wait for Worm Week...
Great video, I had no idea that these existed, keep up the good work guys!
I love sharks and ive been studying them by my self for 7 years now and this was so interesting to learn about because I found this shark had a more fasinating set of teeth than the helicoprion in my opinion.
Water seems to give some of the most peculiar adaptations to organisms. I suppose being subjected to various crushing pressures, some seen, others not. Might have a tendency to cause a few experimental copium dispensers to occur.
Nobody:
scientist: everything with a T gets a silent P!
These sharks are so unique in many ways
It is always the scary creatures who have the derpiest teeth or bones.
shark pog pt2
I imagine the prey were crushed but still alive, almost all of the time, as salt water and stomach acid rushed into every crack and open wound while they lay there crippled and being slowly digested alive. Spectacular animal
These sharks were, like, twice as long as great whites?!?!
😮😮😮
Imagine a shark that bites you like an old man without dentures
This thing is a nightmare for me. I know cutting is pretty bad but crush always seemed like a worse way to go.
Fun fact s Shark’s live longer than trees
Also they can both float because they are made of wood. Sorry but we always needed a Money Python joke!
They're older than Saturn's rings!
it depends on the species
Weird shark core
So basically Giant Cretaceous Nurse Sharks.
Basically the predecessor to the nurse shark
It looks like the top of the mouth of most mammals.
We’re gonna need a bigger boat
I’m happy to see your content in my shorts feed!
"Eventually it was realized"
They look like teeth from a woolly Mammoth ancient elephants.
Them teeth got six packs
Man got osteoderms in his mouth 💀
I bet this shark or at least some species within this group probably had very strong of powerful jaws to mash up its prey with ease
They look like nurse sharks
Crushing down on hard prey 💀
Love your channel Ben. Keep up the good work
Grandpa shark doodoodoo
Nice plants vs zombies instrumental in the background lol
Globidens if it were a shark
I would love to see a video on why sharks lost their dorsal spikes by their fins. It seems like a lot used to have them.
Grampy shark 🦈👴🏽
Called skyrim armor
_Cool_
Wait, a shark
that has a skull? Thought sharks didn’t have bones …
He looks friend shaped
I found one of these last summee
Lol we also KNOW that they PROBABLY gave live birth lol
these sharks were greedy for crunchy prey, perhaps even today they would eat the bones of whales.
We aslo KNOW it PROBABLY gave live birth is a redundant statement.
When all those shelled creatures died off after the kPg extinction these things had no chance
Hydrolic press for a mouth
What if the saw tooth shark is just chewing on an Ammonite before something happened, killing and preserving the shark along with its meal.
😮sooo good. 😀
It’s there a shark today that still have this teeth
Walnut teeth
big fish
Cool_
Teeth horror
I wish I knew what meters were. I assume that’s almost 50ft maybe I’m severely wrong though
close! 14 meters is 45 feet.
When did sharks develop a cartilaginous skeleton? Or was it that way since the beginning?
A better question is why do other things have bones not cartilage, since cartilage fish were first
@@hadiisaboss5307 pressure of gravity as they left the water needed something more robust than cartalidge
@teshlafreeman4040 there's bony fish that are purely aquatic so the adaptation of bone must be for a different reason
@@hadiisaboss5307 what’s your guess then
I love when they call these animals from millions of years ago “prehistoric”, they are so much older than just the measly 5,000 years of human history
Pre: before
Historic: has to do with human history
Prehistoric: a time period with history before human history, any time before 10,000 years basically.
So much for evolution we still have them today 🤣
?
@@lassenker07 OP is a creationist and flat-Earther. Don't expect anything rational out of him.
E
Careful when it gives you the gock gock 9000
Hehe you’re gonna need a bigger boat jokes must surely be in the comments somewhere….😂
Imagine the head it gave 🥴
Get that THING away from me he looks horrifying
:/
Total nonsense
Not well adapted, well designed.
Found the blithering idiot.
Begone creationist!
Adapted.
