Hello

many authors state dates of divergence between taxa but may not cite
primary (or any) references in support. I am after estimates of
divergence times between the following vertebrate groups and would like
references for them:

ray-finned fish & amphibians
ray-finned fish and reptiles (esp. lizards)
ray-finned fish and birds
ray-finned fish and mammals
amphibians & reptiles
amphibians & mammals
reptiles & birds
reptiles & mammals
birds & mammals.

80 million years is a frequently cited estimate for mammalian radiation.
