Neither Peters's or Senter's analysis should be regarded as the Final Word
on _Longisquama_'s affinities. However, most professional researchers put
more faith in Senter's phylogenetic analysis due to certain methodological
problems with Peters's study. As an example of the reasons why, refer to
Nothing personal. It's just that Senter's study set the bar higher than
Longisquama has a single line of dorsal plumes, analagous and perhaps
homologous to the frill on a Tuatara, Iguana and Basilisk.
For the "single line of dorsal plumes" - this is probably the case; not
definitely. The suggestion that the plumes are "homologous to the frill on
a Tuatara, Iguana and Basilisk" is much more speculative.
