The type skull is mostly complete, and a second skull from the same
locality has been referred to this genus. (See The Age of Dinosaurs in
Russia and Mongolia).
Opisthocoelicaudia: a skeleton lacking the skull, the neck and the end of
the tail.
As I wrote before, additional O. skarzynskii caudal material has been
found. Other sauropod remains have been discovered in Nemegtian beds over
the past several years.
