True, the synapsids preceded the dinosaurs. But the dinosaurs didn't
become dominant until the synapsids were largely wiped out in an extinction
(NOT the Permo-Triassic one - the Late Triassic one).
This suggests to me that competitive exclusion, and being "at the right
place at the right time" to take advantage of the depauperate ecology
following a major episode of extinction, are key factors in determining the
large scale success of a lineage.
