#sharkweek #sharkweek2023
If sharks arent the apex predators, the largest shark of the time period is alsways some strange fellow, like today where the largest shark is a Filter feeder
I love how sharks have such a wild history and they're everywhere. Just shows why I love these weird but beautiful animals and this is just a fantastic example
SHARK WEEK LETS GO
But did he have to say Baby Shark ? 🎵🎵🎵
Now it's in my head 🤣
It’s been the same exact shit for twenty years
@@aanntthhoonnyy its been the BEST same exact shit for twenty years
Lets GOOOO!
I know where to find these! Hatchechubbee Creek near eufaula Alabama. Found near HUGE exogyra deposits so probably eating oysters
4:50 I believe Occidentalis is pronounced "OXidentalis" and not "OKidentalis". Like Occident (west) vs. Orient (east). Occidentalis and Orientalis, both appear in the nomenclature of several species.
I was wondering about that
Hell yeah shark week is back
Hope you enjoy!
I see that cheeky ichthyosaur with those sharks on top of the monitor. Bro thinks he can blend in smh
Fun fact: Sharks or their ancestors have existed on this planet for longer than _trees_ have.
Possibly even existed longer than the rings of Saturn aswell
The true sharks (Selachimorpha) fossils have been found no earlier than the Jurassic with possible early Permian fossils also being sharks. Trees have been found from around the Middle Devonian. If you look at the cartilaginous fish as a whole then it would’ve been true, but that would mean including fish that aren’t sharks in the definition of a shark.
@@vinny184 yes, I edited my comment for clarity, because the earliest fossil evidence for sharks or their ancestors are a few scales dating to 450 million years ago, during the Late Ordovician Period.
Emma Bernard, a curator of fossil fish at the Museum, says, 'Shark-like scales from the Late Ordovician have been found, but no teeth. If these were from sharks it would suggest that the earliest forms could have been toothless. Scientists are still debating if these were true sharks or shark-like animals.'
@@Unpainted_Huffhines I haven’t looked into for some time if anything has changed but I doubt it as around 2010 or so a well supported molecular phylogenetic study was done which has been replicated a few times after. Shark-like is often used for proper science communication because everyone knows what sharks are. While lots don’t know about the difference between cartilaginous fish and bony fish.
Not too far from our home in Dallas TX is Post Oak Creek in Sherman. I love finding shark teeth there especially ptychodus teeth.
I would love to find some Ptychodus teeth myself someday! That's so cool!
@@BenGThomas try a Texas fossil trip, you'll love it. Just not right now when the temps are over 100 degrees F.
oh dang and Mr. Thomas might not realize how far Dallas and Sherman are from the Texas Gulf Coast. Hundreds of miles! Five hour drive from where I am on the Gulf Coast! Yah, wow that is really cool I had now idea there were creeks like that, that far north of the coastal waters and I am Texan!
@@nozrep During the Cretacous an inland sea went from the Gulf of Mexico up to Kansas and Nebraska. So, shark's teeth and mosasaur verts and teeth. The neat thing about POC is that it also cuts through a Pleistocine layer and you can find mammoth enamel and bison teeth and stuff. Also, relics from the pioneers.
I'd want to find Ptychotus teeth so I can make a necklace out of it and then confuse the heck out of people when I tell them it's a shark tooth necklace
Hamzah’s drawing is a magnificent. The drawing captures the essence of the subject with vivid colours, dynamic shapes, and intricate details.
Nice to see a video deep-diving into a specific prehistoric animal again, rather than just the Seven Days of Science.
I very much agree and said much rhe same.
Tbf the boys had like graduation to do, so I'm happy for both 😊
It's also possible that they could also eat the giant turtles that lived at this time.
First time i’ve seen a video on this genus, awesome! Great and insightful content, thanks Ben!
So cool to think some of them were t just shelled animal specialist hunters but just making unique use of non conical teeth. I can almost imagine a scene in a movie where they’ve gone back in time, “oh that guy? He’s just an ammonite specialist. Nothing to worry about.” “Steve, Steve! Why is he chomping at me???!” “Wait a min, whoops! Looks like some of them went after more than shelled prey!”
"The las period of the age of dinosaurs" well yeas, but people always forget that it lasted 79 million years, longer than the entire cenozoic era, so the dinos had lot of time to enjoy
Never thought i'd see you in this channel.
Kind of like the Sheepshead fish species of modern days. I mean I know it’s not a shark but as soon as I saw the artist’s picture of those teeth I immediately thought, Sheepshead shark! And sheepsheads target crabs and crush them with sheep-like teeth or human-like teeth, and we humans can catch them and eat them and they are delicious.
The Pacu, a relative of the piranha, has a similar teeth. They generally target fruits but will go after anything that can fit in their mouth. It’s why in some areas around the world they’re invasive pest that eat the local fish stocks.
Hamzah's art is stunning as usual.
As a child, I have very vivid memories of hunting for theeth
he cronchy boi
I'm glad I don't have a hard shell. That means I can swim safely with Ptychodus.
That said, I never expected to learn that Ptychodus gave live birth. Given that it is a K-strategist, it would also likely be a long lived animal.
I wonder when they'd reach sexual maturity then.
There is an impostor on the back there! 🦈🦈🦈🦈🐊🦈
Looks like a shark without its dentures😂
They look like scoots of a crocodile
I sympathize with this shark, I too crave the crunch.
Now that is a new one to me. I had never heard of such a thing. Thanks for posting this expose on it.
Would be nice to see a collab with Yorkshire fossils.
I really enjoyed the depth and length of this video.
What you got against the height?
@julianshepherd2038 Height has its place, true. However, Depth could be considered negative or inverse Height. So I suppose after a fashion I complimented the Height while only using positive terms. 😉🤣🖖
It's so weird having known about this guy before the video.
so you mean to tell me the MEG 3 will be featuring this shark? "scientists measure it to be 4-7M long but others think it could be much larger. and still living in the depths".
you young people are great!
That tooth looks like a damn isopod 😂
I've never heard of these sharks before. Fascinating!
It's really fascinating learn about these prehistoric sharks 🦈 🦈🦈🦈🦈🦈
It's still not easy being a hard shelled bi-valve 😎
I do love shark week.
Incredible video! So excited for the next Shark Week videos!
🦈SHARKSHARKSHARK!!!! 🦈
Shark 🦈❤
Nice video, many thing's have get knowing , many many thank's for this video, now I want to see sarcosaucus vs predator x war, please make a video about this.
I found a very nice Ptychodus tooth a couple months ago in north Texas.
I love the Ptychodus genus. I have a few teeth of P. mortoni on my fossil aquatic predators collection. Great video!
Fascinating video, thanks Ben!
They would have enjoyed Doritos
Giant Prehistoric Crushing Shark sounds like a great name for a rock band
Neat. So many cool sharks have existed in our world's history.
Very nice video, love it. ❤ How is the background music track called? Very soothing!
It's called After All, by Geographer 😁 glad you enjoyed the video thank you!
@@BenGThomas Thx a lot! The choice of music on this channel is excellent!
I actually have one of those teeth. I found it in the Eutah formation at Catoma Creek right next to Maxwell AFB when I was a student at Auburn. For the longest time I thought it was a tooth of Globidens.
Awesome video, you gave this bizarre and interesting shark the attention it needed. It's also nice to see that Hamzah drawing skills are getting better. I admit that you caught me off guard cause I was sure I would've also seen in the video the illustrations by Hodari Nundu, Brian Engh and artbyjrc, which are some of the very few people that managed to do a more up to date Ptychodus, but this of course didn't make the video less enjoyable
A 14.5m/50ft long shark … bloody hell Jack !!!
Regular Shark: "I bite!"
Ptychodus: "I CRUUUUUUSH!!!!"
Part of me wishes that human molars had that kind of structure but at the same time I can imagine that any dental problems would be ten times as difficult to fix.
Ptychodus is my favourite prehistoric size due its combination of big size and unique diet.
i would like more theeth lol!
The name reminds me of one of the outdated theories about Helicoprion
Apparently, Helicoprion is not a shark, it is a holocephalan, whereas sharks (superorder Selachimorpha) belong to the class Elasmobranchii, interestingly, the classes Holocephali and Elasmobranchii are not closely related, the latter is more closely related to bony vertebrates, while the former is the most basal of all the extant jawed vertebrates.
@@indyreno2933 well they’re both cartilaginous fish so there is some relation there.
I was just saying that the fact that this shark reminded me of one of the outdated theories for the Helicoprion’s whirl was they thought it could’ve been used to crush shelled organisms, though apparently now the current theory is actually the opposite since the fossils of helicoprion apparently lack the wear that would be present on a creature that preys on hard shelled prey
@d4rk5t4r2, bony vertebrates are descended from cartilaginous fish, just like tetrapods are descended from bony fish, which is why sharks and batoids are both more closely related to bony vertebrates than to chimaeras and lobe-finned fish are more closely related to tetrapods than to ray-finned fish, this is also a reason why Actinopterygii and Sarcopterygii are both ranked as full classes, the same is also said for Holocephali and Elasmobranchii.
@@indyreno2933 interesting.
I thought Chondrichthyes was the class for the cartilaginous fish, which encompasses Holocephali and Elasmobranchs
@d4rk5t4r2, Agnathichthyes, Chondrichthyes, and Osteichthyes are all invalid taxa because they are all paraphyletic, Agnathichthyes is paraphyletic because lampreys are more closely related to jawed vertebrates than to hagfish, Chondrichthyes is paraphyletic because sharks and batoids (collectively known as elasmobranchs) are more closely related to bony vertebrates than to chimaeras and their extinct relatives (collectively known as holocephalans), Osteichthyes is paraphyletic because and lobe-finned fish are more closely related to tetrapods than they are to ray-finned fish, this officially makes six extant classes of fish: Myxini (Hagfish and Fossil Relatives), Petromyzontida (Lampreys and Fossil Relatives), Holocephali (Chimaeras and Fossil Relatives), Elasmobranchii (Sharks and Batoids), Actinopterygii (Ray-Finned Fish), and Sarcopterygii (Lobe-Finned Fish).
why dose shark week get so much attention when croc week is just ignored.
never mind we still have Croctober.
How come a situation like pampe didn't happen in the prehistoric times
Found one today in Alabama, Tooth was in great shape, better than any I’ve seen online.
Ooooh! Goblin Shark! Looking forward to that!
tell us about those shark relatives please
I bestow you with a high honor, I’ve chosen this video to eat my food while watching
Carnivorous dinosaurs didn't rule the land. Large herbivores did.
Super Nice
That shark pog face.
Nutcracker sharks
a highly underrated animal that I'm glad is getting spotlight!
The gasping teeth and long jaw of Ptychodus, though dissimilar to eagle rays, are quite similar to modern horn or bullhead sharks. There is no single pass to durophagy, and durophagus animals can target rather different prey.
ptycodus skeleton from Texas texasthroughtime.org/wp-content/uploads/2022/08/image2-4.jpeg
shark pog
Ben - A pronunciation tip: - Double-C in English is always 'ks' [With very few exceptions].
Such teeths deviced for breaking shells, animal bones and hardware by grinding under preassure rather than quick effective chops are almost "scarier" than sharp teeth
I found 450 teeth once in the Kansas chalk formation.."shark fossil 3" is the youtube video
The shark can eat all
Perhaps the mouth was elongated and not wide because some prey (ammonites) was a decent swimmer and if larger size than currennt shellfish?
Boy where can we find the thumb's picture? Please put on high quality within the links
A Lot better that Discovery's Shark Week with so called Celiberties and nonsense ...
Who here from the short about them finding fossils with actual body outlines of these guys?
nice
Maybe Ptychodus used those teeth for processing seaweed, which may have contained mollusks. The ridges look similar to wooly mammoth teeth, which didn't eat mollusks.
Mammoths moved their jaw to grind their food, are sharks able to do that?
They look similar to nurse shark teeth. And they hunt mollusks and crustaceans.
Shark week is good.
Worm week is better. Even though I love sharks!
8:83 DOO DOOO DOOO DOO
There was probably a prehistoric shark that was just a giant mouth with no body or tail. It had long sharp teeth that could eat anything in the sea.
I hate that "r/dontputyourdickinthat" is the first thing that came to my head after seeing the thumbnail
Nice
bruh i didnt want to know this thing could get to those sizes with that type of teeth, like imagine getting bit and it just turns your bones into dust
my immediate guess would be crab, or ammonite eating... we will see if i was right
No No Ben G, Ptychodus has to be over 50 meters...at least!
“fascinating ripple like structures” they look like fingerprints!!! i wonder how the similarity arises!!
Prehistoric crushing shark sounds like a Torche song title
Well I’ve helicoprion so not really surprised.
I have found these at my parents farm in Iowa
excellent in depth video and super helpful!
You can find those on the South Carolina coast.
Dude... Actually I have to say that i love these videos. Not only you made me into studying paleontology after gymnasium you are also proof that paleontologists can be actually pretty hot. (Well... at least some of them... Not sorry to you Jack Horner!) I'm glad you make these videos and I can explere some paleo news whole year
The teeth look worn out by acid erosion.
BTW, your "short" totally worked, I saw this video in my bell thingy, but got distracted and forgot, then watched the short and now here I am. Take that for what you will
I can’t find your mums channel
One of my favorites through life history, ptychodus is a cool one. Ive always imagined it as a mix betweed a bullhead shark and a nurse shark with cownose ray teeth
Thank you for this very interesting information! That's one thing I love about science/biology, always learning and growing.
thank u for providing me prehistoric shark content to watch during breakfast haha
Love your vids. Your in depth analysis and attention to detail makes all the difference!
