Note: only three generic taxa are represented here. All the rest are suprageneric. Which leaves open the question, which specimens/genera served as poster child for each of the suprageneric taxa?
Atanassov referenced Peters 2000, so why he chose not to include Longisquama, Sharovipteryx and the others can only be attributed to not being able to personally observe them.
There is also the question of cladistic _analysis_, which MacClade is great at. After thePAUP* tree(s) is(are) created it's time to evaluate it(them). MacClade is great at showing exceptions and mistakes in coding.
For instance, note that all of the sister and predecessor taxa of pterosaurs in Atanassov's phylogeny have a vestigial or absent pedal digit V. Pterosaurs don't. That's a red flag that should tell any reasonable person, evolution doesn't work that way
The same for manual digit IV.
