Just published and available free online (Kellner et al. 2013) bits and pieces (nothing complete or articulated), the world’s largest southern hemisphere pterosaur, Tropeognathus, a crested ornithocheirid from the Early Cretaceous. My, what a big crest you have!
Other than the model maker’s problems (see caption), the paper got it right. Good job.
