Male Pteranodon longiceps

Field guide style drawing of a big male Pteranodon longiceps. The pose is a partial crouch. Most people reckon that all pterosaurs would probably have walked with more or less parasatagial front limbs, and this is borne out by known footprints. But that wouldn't prevent the animal from moving a bit, as obviously the arms needed to splay during flight.

This is specimen YPM 2437, probably an old male, though Kellner 2010 apparently considered it P. sp. tentatively, presumably due to the more upright crest. However, that's probably due simply to ontogenic change, as you can see in my modified Pteranodont profiles (modified to reflect Bennett's taxonomy rather than Kellner's). [link]

Note that Bennett considered "Geosternbergia" maysei an old P. longiceps, but given the weird crest incompletely preserved, and higher strat level, it's probably a distinct species. Bennett argued that all Pteranodon were a single anagenic lineage, so it really should be Pteranodon maysei, even if you want to arbitrarily place P. sternbergi in its own genus.

Soon I'll do a final profiles view with my "preferred" taxonomy.

I feel bad not posting any of my new field guide stuff, which is why I'm throwing all this Pteranodon up. Maybe I'll toss some bit of my new Ichthyornis up into scraps or something as well, since they kinda go together.
