Cauda is Latin for tail, just as Ura (or Oura) is Greek for tail. On a purely lingual basis, I don't see why
one is more valid than the other. However, it is my understanding that Urodela has been replaced in modern
scientific usage by Caudata and that use of the term Urodela is slowly, but surely, dying out. I remember
reading that salamanders and caecilians were sometimes informally known as Caudata, but formally the
Order of Newts and Salamanders is now referred to as Caudata, i.e. that Class Amphibia is comprised of Anura,
Caudata and Gymnophiona (unless something is to be done with the Sirens).
Of course, there are alternative names for the other two orders - Salientia and Apoda. And then there is
Batrachia, which used to refer to just frogs and toads as opposed to its present usage for all Amphibians.
It's all very confusing :).
Incidentally, Shubin's article was in the March 29th edition of Nature (the one with the Spider on the cover,
I believe).
