Open research question
Can the alleged animal reportedly killed near Dongou around the 1930s be traced to an identifiable witness, administrative report, specimen, photograph or other contemporary documentation?
A source, research note, or further-reading link closes this question when staff accept it. Evidence and corrections stay attached for staff and do not close it by themselves.
Staff review every contribution before it is added to the file. A correction is a proposal: accepting it does not replace the official record. Rejected items are handled like rejected case submissions.
