Just a minor quibble. _Triassolestes_ is a fossil dragonfly (Tillyard,
1918), _Trialestes_ is the fossil crocodylomorph (Bonaparte, 1982 - to
replace _Triassolestes_ Reig, 1963).
(Of course, the right thing to do would have been to make up
(a) "Does this make sense?" is a question that too often is answered by
someone who believes that there own opinions have priority over analysis
the data. This is also called "hand-waving".
Often we simply don't know what makes sense. Often the analysis can tell us
what makes sense, rather than vice versa.
(b) Evolution does not *always* work in tiny increments. Here's an
of one hypothesis to the contrary...
An extreme and more obvious case are the turtles: the shoulder girdle is
either outside or inside the ribcage, there can't be any increments (in
amniotes, whose ribs are never as short as a salamander's).
