Re: Where, oh where do those turtles come from?

No, there are at least two of us (and Darren Naish I think makes
Another recent publication which might be of interest is:
Lee, Gow and Kitching ('the Old Man of the Karoo'): Anatomy and
relationships of the pareiasaur Pareiasuchus nasicornis from the
upper Permian of Zambia. Paleontology 40(2), pp 307-335, 1997.
In which a beautiful preserved and prepared pareiasaur skull is
described, again strenghtening the pareiasaur-turtle connection.
Almost forgotten is Eunotosaurus, that strange reptile from the
Tapinocephalus biozone of the Karoo, featuring as the turtle ancestor
in the old paleontology handbooks. In Carroll's 'Vertebrate
Paleontology' it appears again with a new reconstruction, and gets an
indeterminate place within Parareptilia. In his 1993 Science paper,
Lee suggested (by the way) Eunotosaurus was a late surviving and
quite derived caseid synapsid ('pelycosaur'). Does anyone know if the
promised "Eunotosaurus as caseid" paper has already been published
