A large-crested pterosaur

Caiuajara dobruskii is a tapejarid from Late Cretaceous Brazil, 94 to 72 million years ago. It has a wingspan of up to 2.35 meters wide.
They're known from a quite spectacular find that got published in 2014: a colony of 47 individuals of varying ages and sexes were found together, showing possible sexual dimorphism. Being a tapejarid, their large crest and short toothles beak pull our attention, but other special features are a bony projection inside the large opening in the skull and a rounded depression in the outer surface of the jaw.
Note that I didn't follow the exact shape of the crest and depression, but added quite some keratin on top of it. 
Also special is that Caiuajara is the earliest tapejarid and the most southern found. The juveniles apparently also show signs of being precocial, thus being able to fly from a very young age.
