Thanks. Finally I arrived at a head that blends the elements of the skulls from the most closely related species that actually preserve the skull. You can see hints of Malawisaurus, Antarctosaurus, Ampelosaurus, the tiny pieces of the skull we know from Notocolossus, and the Ruyang jaw and partial skull (may or may not be from a Ruyangosaurus). If we had a complete skulls from actual lognkosaurs then my hunch is at least one of them would resemble this speculative skull.
