Description
Ptychodus was a truely huge shark, with a length of 10 metres it is as far as I know the biggest shark that lived during the mesozoic. It lived du´ring the late cretaceous. As a hybodontid, it probably looked quite different than other sharks of it era like cretoxyrhina. It also was a gentle giant, feeding on molluscs and stuff like that.Related content

Oxalaia couldn't have caught a 32 foot long shark.

*** sigh + facepalm***
Oxalaia (a reference to the African deity Oxalá) is a genus of carnivorous theropod. It is a spinosaurine spinosaurid which lived during the ''' late Cretaceous ''' (early Cenomanian stage, about 98 mya) in what is now Brazil....
And if you 'believe' the spinosaurus aegypticus do hunted all of those white shark sized fish; you logically have to believe that the oxalaia can do that either...

And plesiosaurs have such a small head they couldn't have bitten and killed a Ptychodus,the only animal that was from it's time and could kill it would be some type of mosasaur.

That definitely change from species to species...
The plesiosaur's might hunt in groups; they hunt by injure their prey; there are many possible ways; just imagine...
I also meant a little ''' joke ''' in my first comment

Umm I was saying oxalaia cant hunt a shark of that size. Plus if you are smart enough you'll reaalize Ptychodus lived later than oxalaia,and in a diffrent place,and oxalaia didn't hunt in the far ocean. Onchopristis is easy to catch because it's very thin. And Spinosaurus has a top estimate of 59 feet long. Oxalaia 44. Oxalaia lived in brazil,during the Cenomanian of the Cretaceous.While Ptychodus lived from the Coniacian through to the Maastrichtian of the Cretaceous,and lived in North America,the united states.

Look to your comment; if you haven't changed\edited it you exactly said oxalaia didn't lived in late Cretaceous; and I re-answered.
Anyways its very possible to an oxalia to hunt a fish at that size; look to what spinosaurus hunt. Okay ?
Especially look to their size; the smallest one had the great white shark size.
Imagine what an oxalaia could hunt.
True about the timeline thought; but still oxalia's time period deemed late Cretaceous by paleontology too.

Umm ptychodus was much heavier then a onchopristis. Plus the Great white is much bulkier then what either Oxalaia,Suchomimus,Baryonx,Spinosaurus,Or Sigilmassasaurus hunted. The big fish spinosaurus hunted were either slim saw fish,or heavy but still small coelocanths.
Also for some reason I don't see jokes usually.
And there is no reason Plesiosaurs would need to hunt a mollusk eating shark.
Mostly they were small fish hunters,mostly enchodus.
The mosasaurus were fully cabable of hunting ptychodus though.
Prognathodon,Liodon,Tylosaurus,Etc. Probably not platecarpus although.
Im surprised you didn't list Brachuachenuis in there.
It lived around the time of the inland sea and was 32 feet long and was a pliosaur.

Do you even know what ochopristis, mawsonia are ?
Ochnopristis was a both large and fast\agile fish; its anything but slow.
Mawsonia on the other hand was a heavy league; its probably a very strong cocelanth.
I am not sure 4-6 or bigger meter fish could deemed 'small'
Oh; these claws and this big animal can definitely hunt a pytchodus; if they lived in same time same habitat.

That depends entirely on which species of plesiosaur is; and the type of shark
👍: 0 ⏩: 1
Well the only plesiosaurs I can think of being able to do it would be elasmosaurid 12-21 meter long plesiosaurs.

Did you watch the BBC's dinosaur planet ?
In that show a species of elasmosauroid can capable of hunting small to medium sized sharks; its all about the size and agility of plesiosaur

That shark was the size of kimmerosaurus's mouth though.

Think similar to how killer whales hunt blue whale or their infants; by packs with injuring them

But plesiosaurs aren't one of the most intelligent animals on the planet.

They were for their 'own' time period; Jurassic
A species of plesiosaurus; named kimmerosaurus; proved that most plesiosaur specis lived in groups; maybe were even social ! - For a reptile. They were the dolphins of their time; they were killer whales before the larger Predators arrived.

Umm ptychodus was in the cretaceous. the Elasmosaurs were the ones around and were going extinct. last time I checked 
👍: 0 ⏩: 1
Lol ! I know !
I meant the plesiosaur's behaviors were possibly (very high possibly) quite similar
Think about a pack\group of Elasmos'es approaching to you while you taking a swim; not the best type type of wildlife experience

How about a pod of highly intelligent 40 foot long whales.
👍: 0 ⏩: 1
We already have ''Sperm'' (what kind of name is this ?) Whales and Orca's !
But I you meant a large pod of Livyatan's; poor megalodons have no chance !!
👍: 0 ⏩: 1
Unless they have hunt in packs.
👍: 0 ⏩: 1
Who ? Megalodons ?!
No shark species show no signs of intelligence to gather as family units or social groups.
The sharks only gather together as simple ''units'' or so called 'gangs'. These extremely simple (so called) groups; only gather\drawn together to eat. But this eating done entirely by individualy; and if even one shark injures; it (mostly; generally) immeaditely cannibalized by its specimens.
So Social Whales >>> Very simple Shark ''units''

Yet it's possible. And megalodon is pretty sophisticated. for a shark. Never underestimate a animal that has survived over 400 mya.

Well; its pretty sad sharks only shined 'a few' times...
But reptiles, other fishes, even mammalians usually supress & prey on them...
Buuuut; almost all of the Predators went extinct while sharks didn't !!

What about the arthropods. Also sharks were in the middle ground in my opinion.
