The long awaited paper on pterosaur origins by Hone and Benton is now out in
the Journal of Systematic Palaeontology. Hone and Benton reanalyse and reject
the conclusions of Bennett 1996 and Peters 2000, and go with the current
orthodoxy that pterosaurs are 'derived archosaurs' by which I suppose they mean
ornithodirans. However, a recent paper (too recent to have been included in the
Hone and Benton study) by Renesto and Binelli (2006) in Riv. Ital. Pal. Strat.
on Vallesaurus concluded that pterosaurs grouped with Drepanosauridae, and that
this clade was located between basal archosaurs and protorosaurs
(Prolacertiformes). Topographically speaking this is only one step away from
Bennett's hypothesis and also corresponds quite closely to the ideas espoused
in The Pterosaurs. That said, much remains to be said and done on pterosaur
origins. Hopefully, some of this will happen at the forthcoming Flugsaurier
meeting in Munich in September (http://flugsaurier.blogspot.com
<http://flugsaurier.blogspot.com/> ) and for which you still have time to
register and submit an abstract.
Anyway, its back to the cricket with England on 85 for no wicket at lunch on
the first day.
