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

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 ("philanthropist" OR "philanthropists"))).
• Removing quotes may allow a broader search: ( philanthropus or ( philanthropism or ( philanthropist or philanthropists ))).
• Adding a wildcard symbol may retrieve word variants: ("philanthropus" or ("philanthropism" or ("philanthropist" or "philanthropists")))*.
