Fllugsaurier – Porstmouth 2015
is scheduled for August 25-29, 2015. Flugsaurier is a gathering of pterosaur experts eager to discuss their latest finds and hypotheses every two-three years. The last Flugsaurier occurred in Brazil 2013, with pictures here.
The fourth circular
just arrived and iincludes symposium and poster session titles and presenters. Some interesting talks are scheduled. My comments follow selected topic titles.
Chris Bennett and Paul Penkalski:
Waves of bone deposition on the rostrum of Pteranodon
Good news that someone else recognizes this. Laminated bone is present in all pterosaurs, promininent in Pteranodon and other large pterosaurs. The jugal and nasal both extend anteriorly more than traditionally thought. And that ‘layer’ at the tip of the rostrum (and mandible) in Pteranodon is a tooth. Of course, ontogenetic growth is also a likely suspect for those waves of bone deposition, but we’ll see what they say. I’d be interested to see how precise the interpretive drawings are.
Breithaupt, B.H., Matthews, N.A., Connely, M.V. and V.L. Meyers:
Pterosaur terrestrial locomotion, pterosaur tracks, and photogrammetric ichnology of Pteraichnus and other ichnotaxa
But will they discuss the pedal without manus tracks featured in the pterosaur heresies and in Peters (2011)? Witton’s comments on pterosaur ichnites are a bad omen for this.
Brooks B. Britt, F. M. Dalla Vecchia, D. Chure, G. F. Englemann, M. Chambers C. M., Thelin and R. D. Scheetz:
A new Triassic pterosaur from interdunal desert deposits of the Nugget Sandstone (NW Utah, USA
This is good news.
Xin Cheng, Shunxing Jiang, Xiaolin Wang and Alexander W. A. Kellner:
A new anurognathid pterosaur (Pterosauria, Anurognathidae) with complete skull and long tail from the Jurassic of China.
This is good news. Click here, here and here to see other anurognathids with a long tail.
David W. E. Hone, X. Xu, S. Jiang and J. R. Hutchinson:
The return of the holotype of Noripterus (Young, 1973) – implications for dsungaripterid taxonomy and a possible digitigrade pterosaur.
Digitigrade pterosaurs? Like I demonstrated in Peters (2000, 2011)? OMG!! Everyone has hated this (despite the evidence, for 15 years… and glad to see Noripterus is being retained.
Shunxing Jiang, Xiaolin Wang and Yingxia Ma:
A new archaeopterodactyloid pterosaur from the Jiufotang Formation in west Liaoning, China.
This is good news. Unfortunately the clade is not monophyletic because it contains ctenochasmatids. Click here for pterosaur cladogram.
Mark P. Witton:
Flight performance and lifestyle of Dimorphodon macronyx
With Witton’s interpretation of deep chord wing membranes and a single uropatagium stretched between the legs, this is going to be a head-scratcher lacking a basis in valid restoration… unless he has become a narrow chord dual uropatagia advocate, as shown here and going back to Peters (1995, 2002).
Alexander W. A. Kellner:
Triassic pterosaurs and ontogeny
Kellner (2015) has already followed reptileevolution.com in showing that all known Triassic taxa are not juveniles, but distinct genera, which Kellner named. Kellner did so without a phylogenetic analysis. In a separate email I challenged/asked Kellner to name all the nameless tiny pterosaurs of the Solnhofen, all of which nest separately in the large pterosaur tree, which you can see here.
David M. Martill, Steven U. Vidovic and Helmut Tischlinger:
A new pterodactyloid pterosaur from the Santana Formation of north east Brazil<
This is good news.
Matthew A. McLain and Robert T. Bakker:
Pterosaurs from the uppermost Morrison Formation at Como Bluff, Wyoming: A possible dsungaripterid from the Jurassic-Cretaceous transition.
This is good news.
Steven U. Vidovic:
Characterizing pterosaurs: the quality of anatomical characters in cladistic analyses
Wish I could see this. But the real problem has been taxon exclusion of the tiny Solnhofen pterosaurs.
David M. Unwin and D. C. Deeming:
Growth rates and their constraints in pterosaurs.
Hopefully they will discuss isometry in ontogeny, not the traditional false allometry.
David M. Unwin:
Non-pterodactyloid monofenestratans – rewriting the evolutionary history of
Hopefully Unwin will have rewritten what he wrote in prior papers. If not this presentation will be bogus. Darwinopterus and kin (his basal monofenestratans) represent a dead end in pterosaur evolution as documented here and here.
Charlie A. Navarro, Tom Stubbs, Liz Martin-Silverstone and Emily Rayfield:
Evolution of pterosaur feeding systems
Wish I could see this. Hopefully they will use a valid cladogram if they are going to discuss pterosaur evolution. One can be seen here.
Rodrigo V. Pêgas and Alexander W. A. Kellner:
Preliminary mandibular myological reconstruction of Thalassodromeus sethi (Pterodactyloidea: Tapejaridae)
Wish I could see this.
Matthew A. McLain, Brad Chase and Ryan Devlin:
Addition of footprints and thin sections to the online pterosaur database PteroTerra.
Wish I could see this. A database of pterosaur tracks has been published in Peters (2011).
Shunxing Jiang, Taissa Rodrigues, Xin Cheng, Yinxia Ma, Xiaolin Wang and Alexander W. A. Kellner:
Brief report of two new specimens of Istiodactylidae (Pterosauria, Pterodactyloidea) from the Cretaceous of China
This is good news.
Unfortunately, I am not attending Flugsaurier 2015
because the climate for my interpretations and hypotheses is still stormy despite showing my work online. On the flip side, I think some of the participants and conveners are still clinging to invalid ideas, as touched on above and otherwise sprinkled throughout this blog over the past four years. Things have to change first.
