nothosaurs

[dinosaur@museum.gla.ac.uk]

Hi,

I have recently been given a couple of nothosaurs on a photograph to 
identify, but am having a bit of trouble.  To me they look fake, but 
someone may know on what species they are based.  All comments are 
welcome.  All I know is that they are about 20cm long and from China.

I have mounted them on my web site at: 
http://www.gla.ac.uk/~gxha14/notho.jpg

 What does Keichosaurus look like?  Are they pachypleurosaurids?

Thanks in advance,

Neil
