South america, 12 million years ago

Two primitive lophoraptorids of an unnamed species (yet, it was found in 2010) rest on the back of Purussaurus brasilienis. Some other dragons of the same kind fly in the background and one is landing next to the couple on the crocodile.
These guys look tiny but remember that Purussaurus had an estimated lenght of 15 m.
