Mamalian evolution was very slow for a long time, until the extinction
of the dinos.  The dinos also got their big break after an earlier mass
extinction.  The Cenozoic mammalian radiation was very fast compared to
the dino radiation.  Ditto for birds, doubtless helped by the extinction
of Pterosaurs.  For details, see Paul Serano's review of dino evolution
in Science, vol 204, pp2137-2147, esp p 2143 (25 June 1999).
