Rousseau h. flower (1913-1988) collected and published widely in paleontology during a career that spanned more than 50 years. Although Rousseau did significant paleontological work while employed elsewhere, the major part of his career was spent at the New Mexico Bureau of Mines and Mineral Resources (NMBM&MR), a career that included a decade of work after his formal retirement (Wolberg, 1988). During his life, Rousseau built a very large fossil collection based upon his own field work., materials other scientists referred to him for study, material sent to him by serious amateurs, and collections Rousseau borrowed from other institutions and was unable to return before his death. The NMBM&MR is attempting to find and return all borrowed material. Similarly, we intend to transfer much described fossil material to major repositories with appropriate facilities for their maintenance in order to make the fossils available to as many interested students as possible. The guidelines for the transfer of this material were set by Rousseau before his death.
