If tha 1rst thing that came to yo mind was butterfly turtle, then we in the same goddamn boat. This was Henodus and he was an odd lil rascal. He may look quite like a lil turt-turt, but there were some anatomical differences as well yo. Turtles got limbs situated inside their ribcage where this rascal had normally positioned limbs (not that you can tell cuz of his funky lil shell).

Even with his “normal” limbs doe, they were apparently pretty weak (doesnt even lift) and suggested lil Heno spent little to no time on land. The water called to lil Heno and he answered. Although Henodus is a placodont (marine reptiles usually not very large) he seems to be an exception cuz he lived more in brackish (salty-fresh water) or fre$hwater lagoons rather than tha big open sea. 

Anyways, Henodus lived in the waters of the Late Triassic. Being a placodont, he usually never got bigga than a meter long (tree feet). Besides that strange lil rascal on his back tho, another funfact characteristic was that he only had 2 teeth! One on each side and a beak in da middle. 

Not much tops da Henodus in terms of strange water dinosaurs. He was a swimming bloq if yu aks me.

If this pic looks famfam, its cuz its me yo! Naw, its just my icon cuz there a special place in my <3 for the Basilosaurus. My first post was akshully devoted to this rascal, but I figya’d I ought to go mo in depth. Anyway, dont let the “saurus” part of his name trick you. He aint a reptile at all but instead a whale! When yu think prehistoric whale, Basilosaurus needa come to yo mind. Due to his misleading name tho, other scientists wanted to rename him Zeuglodon to portray his mammal side. However, once a name is given, that name sticks (lyk a misleading super glue of false).

Big ol Basilo roamed && ruled the seas of the late Eocene. They grew up to  18 meters (60 ft) and had quite different anatomies compared to modern whales. Basilo wasn’t quite suited for deep swimm'N and his movement apparently looked strange (based on his muskles yo). fun fact!: my boy H.Melville has a few ch. devoted to these bois. Either way tho, he was a bad bxtch and holds much respect from this simple water-dino enthusiast.

Whale, whale, whale, what do we have here? Big, beautiful Basilo baby makin 

Plz focus yo attention to Leedsichtys, the giant ass fish. Leedsichtys was a pachycormid (prehistoric bony fish) that lived in the seas of the Mid Jurassic. These fish were among the largest to eva inhabit our lil ball of water and rock, but exactly how big is subject to debate. Unfortunately the fossils of these gentle giants may be pretty plentiful, but they are almost all incomplete or missing something. Some scientists say they are  round 9 meters, while others be claiming they around 16. Either way, they some big ass fish.

However, like some big fish of our time (whale shark, basking shark, etc.) these guys were filter feeders and mainly ate zooplankton. One thing thats fo certain tho is that Leedsichtys were champs. They had few predators and some fossils show Liopleurodon sized bite marks, but with signs of healing. So some big pliosaur took a bite, and Leedsichtys was just like bitch plz heres my tail. Tail says smack. 

Now earlier, I mentioned the T-Rexs ov da sea, aka the Mosasaurs. Just how the Elasmosaurus is a Plesiosaur, and the Shonisaurus is an Ichthyosaur, the Tylosaurus (^ pictured yo) is a Mosasaur. 

The Tylosaurus was one of the bigger mosasaurs, growin all da way up to 15 meters (49 feet) or mo! Das a fitty foot sea serpent with fins and big ol teeth. Apparently, monitor (not yo computa screen silly!!!) lizards and snakes r said to descend from this leviathan. 

If yu aks me, the Tylosaurus deserves to be in the category of T-Rexs of the sea. A certain characteristic special to them was their cone-shaped snout. None can say fo sho, but it is thought they used this to ram and stun prey. Tylosaurus was one badass muv no doubt bout it. 

Pokemon Tylosaurus would be way stronga than that (over 9000 everything imo)

Next up we got the dentist’s nightmare! Im jp its the Helicoprion. These prehistoric sharks lived quite a long time, dating all da way from the late Carboniferous, through the Permian, and becoming extinct a good deal into the Triassic. In terms of other prehistoric water dwellers that weve gone ova so far, this rascal has occupied about the longest time period on da timeline yo.

But in all truths, not much is known about good ol Heli besides his teeth. In fact, the only fossils of him are his teeth and all else about him must be hypothesized (still educated guesses doe). It is often debated where his lil twirl of teeth was located, whether in tha front (like in the pic above) or deeper in his throat. Below is another depiction yo.

It is even thought that his teeth are kinda like tree rings. Each year he gets a new one pushing all the smaller teeth farther down tha twirl. So big granddaddy sharks got themselves quite a twirl while lil babies prolly only got lil ones. Now before you go callin Helicoprion a tree, remember he a shark and he would eat you before you do.

See he comin for you right thur ^^^ I told you you shouldnta called him a tree!!
