Phylogeny of Drepanosauridae (Reptilia: Diapsida)
Previously the abstract has appeared on the list. A look at the text and
figures reveals some errors.
1. The taxa I, and others, found to be closest to the Drepanosauridae
(Protorosaurus, Borepricea, Jesairosaurus) were not included. Most of the
problems and major hurdles would go away with the inclusion of these three
taxa. Only 20 taxa and 73 characters were included in Senter's analysis. Twice
as many characters would help.
As a result Longisquama + Coelurosauravus were found to be the outgroup to the
2. The taxa I (Peters 2000) found to be closest to Longisquama (Sharovipteryx
and the Pterosauria) were not included in Senter's analysis (ignored, according
to him out of "laziness" [direct quote]).
If you don't invite the right taxa to 'the dance,' you end up with less than
optimal results. Unfortunately, I don't think any of Senter's proposed clades
nomenclature will prove valid or useful, and the relationships of the drepanos
to others have not been elucidated.
His redefinition of 'Prolacertiformes' to include all taxa more closely related
to Prolacerta than to Archosauriformes will probably only include Prolacerta.
Protorosauria is the senior name for the clade to which Senter alluded and
Protorosaurus is at its base.
