Vertebrate phylogeny

[Emmet O'Brien]

  I am seeking references for divergence dates between:

   1) fish and tetrapods
   2) mammals/birds/reptiles and amphibians 
   3) birds/reptiles and mammals
   4) Rodenta, Lagomorpha, Primates and Artiodactyla

  Please reply by mail. Thanks in advance,

                                     Emmet O'Brien
