Not an intermediate... it is considered a sister taxon to both the nothosauroids and pachypleurosaurs...

Ah, so it's a really primitive eosauropterygian, maybe related to Wumengosaurus

Or maybe even Claudiosaurus, or is the position of Claudisaurus really unsure

I doubt it. I don't think anybody has ever considered Claudiosaurus to be an eosauropterygian?

Well, I have this rather old book, called 'The Illustrated Encyclopedia of Dinosaurs and other Prehistoric Animals' (hope that's the right translation, I have the Dutch version), which claims there is a reasonable chance Claudiosaurus was a sort of proto-sauropterygian, but apparently that theory has not been widely approved of...

But this one already is more primitive than Pachypleurosaurs, right

Did I? I thought I said it's a sister taxon to the pachypleurosaurs... sorry!

Well, you said "it is considered a sister taxon to both the nothosauroids and pachypleurosaurs", so that would mean it would either be closer to plesiosaurs than any nothosaur, or it would be more primitive.
