Perhaps you should try some spelling variations:
"philanthropus" » "philanthropist", "philanthropies", "philanthropy"
"philanthropism" » "philanthropist", "philanthropinism", "philanthropismus"
"philanthropos" » "philanthropy", "philanthropists"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ("philanthropus" OR ("philanthropism" OR ("philanthropic" OR "philanthropos"))).
• Removing quotes may allow a broader search: ( philanthropus or ( philanthropism or ( philanthropic or philanthropos ))).
• Adding a wildcard symbol may retrieve word variants: ("philanthropus" or ("philanthropism" or ("philanthropic" or "philanthropos")))*.
