Description
Pacific bat turtle (Pteromedusa velonectes) differs from the Atlantic congener in smaller size: the length of the adult reptile exceeds 5 meters seldom, and usually exceeds 4 meters only a little. At this reptile colouring of body is gray-blue without dark spots. Sometimes the reptile gets an appreciable greenish shade because of symbiotic green algae settling on its skin. Forward flippers of this turtle are narrower, and back ones are more lengthened, rather than at the Atlantic species. This turtle swims faster, than the Atlantic species. It also differs in greater aggression, and frequently attacks the enemy: some sharkodiles have deep scars on a body, and sometimes the tip of the flipper at them appears bitten off – these are traces of counterattacks of turtles of this species. Pacific bat turtle eats mainly pelagic invertebrates – jellyfishes and gardenersalpas. It breeds at Hawaii, swims upstream in rivers and lays eggs in soft forest ground.Related content

So sea turtles disappear?
My problem is turtles are morphologically conservative, I'm unsure the bat turtles are probable.
It's a cool animal though. Maybe some platypus descendant would evolve similar forelimbs? If their weird way of swimming could ever evolve into subaqueous flight that is.

Sea turtles will disapper because their numbers are too small, but at the same time will extinct the big sea mammals. It could clean theniches of big sea herbivorous mammals and the turtles can succesfully evolve.
I don't think that platypus would evolve like this turtle, because now it has very reserved way of life and it is carnivorous. In the neocene there are some descendents of platypus, but the have preserved on the whole the way of life of the ancestor.

I was referring to the wing-like front flippers, not to the animal's feeding habits. The platypus-type locomotion is held to be intermediate between quadropedal paddling and otariform locomotion. Whilst the platypus fingers are already splayed out like a wing, sort of. If you can imagine a patagium behind the forearm, like a penguin's. you get a stiffened 'bat-wing' type structure.

what did this evolve from and could you do one of a Atlantic congener

From some kind of terrestial turtles. I would make the scene with this animals soon also in 3d.
