Re: Longisquama OFFLIST

So, I guess this was "For Paula's Eyes Only", but by the grace of God it arrived on this list...

Longisquama is most closely related to pterosaurs as I showed in a 2000
paper in Revista Italiana and in later analyses that were much more
comprehensive. Senter's analysis used too few taxa and too few
characters to nest anything with confidence, but instead relied on

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 http://dml.cmnh.org/2007Jun/msg00140.html

Nothing personal. It's just that Senter's study set the bar higher than Peters's.

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.
