William,

As long as you include Lagerpeton and Dromomeron, and especially  
pterosaurs, as dino-sisters, you're going to have trouble with the  
origin of dinos. Take a longer look, start with Prolacerta and  
Protorosaurus then throw everything that succeeded it in the Triassic  
into the tree. Maybe use Hylonomus and Captorhinus as outgroups if you  
insist on using pterosaurs.
