My biggest catch is Typhon in the desert in Morocco....recorded by Hesiod and Appolodorus. I have a vid on my Channel about him. "[1.6.3] When the gods had overcome the giants, Earth, still more enraged, had intercourse with Tartarus and brought forth Typhon in Cilicia,95 a hybrid between man and beast. In size and strength he surpassed all the offspring of Earth. As far as the thighs he was of human shape and of such prodigious bulk that he out-topped all the mountains, and his head often brushed the stars." The vid is called "The Truth about Dragons and Giant Serpents Far Exceeds the Myths". Thank you.
Why don’t you get to think and make a suggestion creating another RU-vid Videos Shows that’s all about the Extinct Prehistoric Amphicyons (Bear Dogs) on the next Extinct Zoo coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍
The segment of Penza and the quadrant's size are based on the outdated belief that the mosasaurus possessed a 1:10 skull to body length ratio, based off of tylosaurus, but a 2014 study, along with finding the mosasaurus to be more robust than previously believed, reevaluated this down to a 1:7 ratio, although the ratio is now believed to be around 1:7.4. Penza under these ratios, would be around 12.5 metres long and 10.3 tonnes, while the quadrant, after a gdi analysis by faedino, would measure 14.5 metres and 15.9 tonnes. Also, the paper did confirm tylosaurus have the 1:10 skull to body ratio, and a specimen called bunker was estimated at 17 metres and a mass of over 17 tonnes, again from a gdi from faedino, although this mass estimate is still a work in progress. (I think)
lol. Actually, River is in the meaning of the Mosasaurus' name, and Moses means: "[She] brought [him] out of the water". So Moses and the Mosasaur might have similar linguistic origins in the meanings of their name
@@twinturboray This is correct, I live next to the Maas in Maastricht and this is also the place where Mosa saurus skeletons are found now and then. We have one displayed in the local museum. My dad was part of the crew that found it.
Curiously, just a few hundred yards behind the Mosasaurus skeleton were found the remains of a whole school of Egyptosaurs. Seems they'd been caught in some kind of marine disaster.
It's terrifying to think of a Monitor the size of a Mosasaurus, i used to have a Nile Monitor back in my early 20's that I took from a friend who wanted to get rid of it, it was maybe 2 feet long with it's tail and mean as hell, handling it was not fun
I was given a 5 foot Nile monitor, wicked creature! If it got out, I had to throw a blanket over it. Not only did it have a vicious bite, but it would whip you with the tail!

What about Cretaceous Pliosaurs such as Sachichasaurus or Monquiasaurus? They were similar in length (probably a bit shorter), but way bulkier than any mosasaur. And btw, Mosasaurs didn't rule during the entire Cretaceous, instead, they dominated the oceans during the last 20 million years of the cretaceous. Nevertheless, great video
@@elmochomo8218 I'm very sorry if I expressed myself wrong, but English is not my native language. I just wanted to point out a couple of mistakes made in this video.😕
We know dinosaurs from their genus names only. Animals living today although we know them by their common names, have hard to remember genus and sub genus names too. The African Elephant is named Loxodonta and the European Rabbits are called Oryctolagus
That’s the problem. Most extinct prehistoric animals, especially dinosaurs, aren’t given common names. Although there are a few select extinct mammals that are more known by their common name given to them than their scientific name (like saber toothed tigers, wooly mammoths, and dodo birds).
@@boomerixThat’s not a common name. That’s just an abbreviation of their genus name. So no, you are wrong, you can’t argue that, unless you want to look dumb.
@@greekfire7980 They may be based on the long genus names, but are the every day use version where most people know what is meant. The other way around, the species name "Canis familiaris" for example is just "Family dog" in Latin. The genus "Canis" literally just means Dog. So by your logic "Dog" is also "just the genus name".
That's artwork from Gaelle Seguillon, one of the artist in Prehistoric Planet project. That art piece was used as the concept for the _Mosasaurus_ spa scene in episode 1 season 1 of Prehistoric Planet.
The Mosasaurus has been getting a lot of fame recently thanks to Jurassic World and rivals that of the Megalodon and the more I learn about this prehistoric predator of the seas, the more it becomes crucial that we all need to except the fact that the world was full of amazing and equally terrifying animals of the past. Bravo!
Isn't it argued that snakes also evolved from monitor lizards? I believe snakes by then had already lost their feet; Mosasaurus probably evolved directly from monitor lizards and their feet evolved into fins.
This phylogenetic theory has been discredited. Snakes are today believed to be part of a different lineage of lizards (Ophidia) than varanids (anguimorpha). Interestingly, many studies indicate that mosasaurs are within Ophidia and that they represent a sister clade to Serpentes, however this has not been proven.
I think my favorite part of your videos, something I never see in other similar channels, is how you cover such a wide array of contemporary species in the area! It paints so much more of a complete and vivid picture of the ecosystem!
@@prashantmishra9985 Megalodon ruled after Mosasaurus went extinct. Because Megalodon hadn't yet evolved when Mosasaurus was around. Deinosuchus wasn't a sea animal. It was a river animal.
To me their closest living relatives are probably monitor lizards, snakes could be a contemporary but the overall body plan of a Mosasaur isn't far from modern day monitors, especially water monitors. Just look at the skulls of both and you can tell they're linked and I wouldn't count out the possibility that Mosasaurs eventually over 65 million years slowly evolved to go back on land and become what would become the likes of Megalania a giant Komodo Dragon and a splinter group retained their water like tendencies to become water monitors like the Asian water monitor lizards today. That's my theory but they were probably the most formidable marine predators of their time and could probably rival most today if the Earth was warmer like it was back then.
Fun fact: there's a lot of debate on if snakes evolved losing their legs on land or in water. So it could easily be that snakes evolved from a mosasaur line directly.
Besides your consistently great research and overview, it's refreshing to see sophisticated CGI animations of its speculated appearance and hunting behavior. Forgive me if I missed an included credit, but what's the provenance of the mososaur animations for this episode?
It appears that they might have but were relatively few in numbers and smaller less of the ocean kings and more in the back were they there the entire period? Most likely not but they may have started off as fresh water animals before moving into the sea
I know this is about mosasaurs, but I lost it at 7:16 seeing Shastasaurus Pacificus. Look at them, they're so round and rotund! Another predator that is friend shaped to perfection. ; w ;
The first Mosasaurus Hoffmannii is currently in France that stole it in 1795 during the French occupation of Holland, it's still there 😁I think we would like to have it back
Anyone else find it funny at 14:25 where hes going through all the scientific names for the other dinosaurs it lived alongside, pronouncing them perfectly and just slips in sand sharks ahhah.
I personally think you should make a video about the sauropods Seismosaurus, Barosaurus, Argentinosaurus, Patagotitan, Sauroposeidon, and Dreadnoughtus. I would love to see that! i love to find all of the fascinating facts about the prehistoric mysteries.
tylosaurus. P was larger than Mosasaurus. H - most recent estimates for the largest individuals are around 17-19 tons with a higher estimate of 22 tons being possible. By comparison Mosasaurus. H was around 10 tons with 15 being possible but unlikely.
Since we're talking about the largest Cretaceous carnivore wouldn't that be Spinosaurus? Estimates for Spino are larger than T-Rex and Mossasaurus but T-Rex was more bulkier
Last time I heard, Spinosaurus is currently estimated to be longer than T. rex but not as heavy. It sounds similar to how the giant squid is generally considered longer than the colossal squid, but most of the verified evidence suggests colossal squid has the greater maximum weight, due in-part to its bulkier proportions. And since mass is usually the go-to metric for size, that would still make T. rex the record holder for largest land predator. That is, unless some new specimens/studies come out suggesting the Spinosaurus’ maximum size was greater then previously thought.
I really find it incredibly tedious that TRex is constantly flaunted as the supreme predator of all time. Yes, it was an amazing apex predator but there are so many more in prehistory that were just as awesome if not far more so. The marine predators are definitely among those as must be the giant pterosaurs and indeed so many groups both pre and post dinosaur.
I love this channel, since that i was a little boy i was obsessed with dinosaur and the origin of the life on Earth, but i never had believed in the Bible.
Never read the bible or any other religious texts my friend. They are all works of man made fiction. Stick to dinosaurs, as this actual scientific fact that predates the bible nonsense by at half a billion years.
Speaking for myself, I would go further and say that Mosasaurus is my favorite prehistoric marine beast in general. To me, it strikes this uncanny balance between being familiar (like Megalodon, Livyatan, etc.) yet also looking more otherworldly/mythical (like the ichthyosaurs, plesiosaurs, etc.). Plus, it is not very common to see a top niche in the Mesozoic ruled by an animal so closely related to the smaller animals of our modern age.
I’ve found some estimates for the largest specimens of mosasaurus including fragmentary specimens and they’re absolutely mind blowing by how big the estimates place the specimens at but this isn’t confirmed so I’m not sure if it’s accurate but I’m still gonna share what I saw in the estimate: (I’m only gonna include the top 3) First specimen: CCMGE 10/2469 (Penza specimen): Lower jaw length: 171 cm Total length (min and max): 15.39-17.1 meters Weight (min and max): 19,446.1-26,675 kg Bite force (based on S. Merianae): 104,911.6 newtons Bite force (based on D. Guianensis): 112,080.8 newtons Next specimen: NHMM 603092 (fragmentary specimen + largest of the 3) Lower jaw length: 230 cm Total length (min and max): 20.7-23 meters Weight (min and max): 47,318.1-64,908.2 kg Bite force (based on S. Merianae): 189,795.9 newtons Bite force (based on D. Guianensis): 202,765.7 newtons Last specimen: TSMHN 11252 (fragmentary specimen) Lower jaw length: 202.3 cm Total length (min and max): 18.207-20.23 meters Weight (min and max): 32,198.2-44,167.6 kg Bite force (based on S. Merianae): 146,832.8 newtons Bite force (based on D. Guianensis): 156,866.6 newtons Sooooooo yeah I guess mosasaurus might have actually been comparable to an average Megalodon in both weight and bite force
And some people think orcas will dominate for some reason as if there isn’t tons of predators that can repel orca pods and feast on calves when they have the chance. Doesn’t mean much when you lose tons of calves each year to predation and the stresses that come from that. It is hell from whatever isn’t adapted to live in it
Awesome video as always. And something for your consideration: I've found myself skipping over the promo "teaser" and missing content because I thought it was the promo, which came later. I dunno, obviously you know better but I'm not sure about the promo teaser thing :)
Mosasaurs did not "rule during the entire cretaceous period", not even close. The very first mosasaurs only show up in the fossil record about midway through the cretaceous, and they aren’t really big apex predators before the last few stages.
The Mosasaur probably swam very similarly to Mondern day Monitor lizards and Crocodilians, which use their flattened tails like an Oar moving it from side to side which makes even the Largest Montior lizards like the Komodo Dragon swim at a Quick 12 MPH in water. although the Mosasaur would have been faster and more maneuverable .
Trex is praised cuz allegedly he had the biggest bite force per mass. Never heard anyone claim it was the biggest, because it wasn't even the biggest carnivore on land and sea has always had the most massive creatures at any time.
