Thanks. I looked at the bibliography and have commented. The reference for this cast was a book with Lucy in the title. Whatever the actual original literature is concerning this cast is ostensibly in that book: Johanson, D. & Edgar, B. (1996). From Lucy to Language. New York: Simon & Schuster Editions

Note the publisher and scope. It is a lay popular book.

The discussions here are usually so far away from the original research it is not possible to comment in any way.

The same bibliography also cites t.o., about equivalent to citing some creationist web site. MOS also has on its featured exhibit : Star Wars: Where Science Meets Imagination

You'll just have to try the library.

This is one of the finds made since I left grad school, so I haven't studied it directly. Some of the other ones I post I have actually studied the casts (Taung baby, Mrs. Ples, etc.).

You will probably find a lot of what you are looking for in American Journal of Physical Anthropology and similar sources.
