Correct me if I am wrong, but perhaps mesosaurs were ichthyosaur ancestors. Think about it; both creatures are marine reptiles and give birth to live young.

Mesosaurs are completely unrelated to icthyosaurs. It appears that aquatic reptiles all evolved vivparity independantly.

That makes one wonder why turtles haven´t evolved viviparity.

Because of the fact that they, like birds, have hard shelled eggs. Their e,bryos develop the skeleton from the calcium reserves in the egg shell; loose the egg shell, and you cannot develop a skeleton.

As opposed to other amniotes, which develop their skeleton from calcium in the yolk.

I would have liked mesosaurs to stay around a bit longer. They were nifty critters. And they could have become niftier...

Indeed. The coolest marine reptiles were the ones with the shortest lives

What about plesiosaurs? They were around for almost as long as the dinosaurs were.

Now THAT'S an obscure aquatic reptile... (And very silly-looking as well!)

While I don't endorse Wikipedia on many ways, their page on hupehsuchids is decent.
