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.

The segment of Penza and the quadrant's size are based on the outdated belief that the mosasaurus possessed a 1:10 skull to body length ratio, based off of tylosaurus, but a 2014 study, along with finding the mosasaurus to be more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.

[@SarastistheSerpent]

This phylogenetic theory has been discredited. Snakes are today believed to be part of a different lineage of lizards (Ophidia) than varanids (anguimorpha).

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.

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

[@markcobuzzi826]

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.

[@arijit3110]

Size is determined by weight not length.

[@MaximumPrime]

Trex is still heavier than Spinosaurus but not longer

1:30 I thought extinction was already known of at the time that the first mosasaur was discovered. The dodo had already vanished more than a hundred years prior. My impression was that, since this was before Darwinian Evolution was introduced, almost everybody was a creationist who believed that all animals were brought into existence at the same time as humans. This led to the belief that it was impossible for there to have been species that went through their entire existence without ever encountering or being encountered by humans. Giant marine lizards were *definitely* not something that any human had ever seen or written about, despite the fact that they definitely would have been seen and written about if they existed concurrently with us. The "impossibility" factor wasn't that a species had or could go extinct, but that it existed at a time before humans and therefore threw their entire creation mythology (as well as the religion based on it) into question. We're still seeing the fallout from that whole mess today.

Surprising seeing the first 2 things they thought it was that the Genus didn't become Suchocetus or "Whale-Croc"

[@Ornitholestes1]

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.

Technically the largest carnivore ever to exist is the blue whale.
