I'm trying to find this paper: Rich, T. and Rich, P. (1989). “Polar dinosaurs and biotas of the Early Cretaceous of southeastern Australia.” National Geographic Research, 5(1): 15-53. I cannot find it at all except for in references, not even a hard copy of it. I'd really appreciate it if one of you could be able to find it.
Update: Someone on Facebook found it for me.
