Jeff Martz has recently colo(u)rized his Poposaurus gracilis reconstruction and here it is in its new glory.
When I see reconstructions of pseudosuchians in a bipedal stance I always reflect upon the question of whether or not it is functionally possible for an animal with a crocodile-normal ankle type to actually be bipedal, especially an obligate biped. I've perused the literature but have found very little to address this problem. I'm certain that Emma Schachner dealt with this in her recently completed PhD on the new equisitely preserved Poposaurus specimen from the Chinle Formation in Utah, but unfortunately I've not had a chance to borrow and read a copy. Her 2009 SVP abstract suggests that myological developments differ between bipedal pseudosuchians and bipedal dinosaurs, suggesting that these myological changes compensate for the alternate ankle structures.
