-gerous

Also ‑igerous.

Bearing some specified thing.

From Latin ‑ger, bearing.

Examples include dentigerous (Latin dens, dent‑, tooth), having teeth; ovigerous (Latin ovum, egg), bearing or carrying eggs; and setigerous (Latin seta, bristle), having bristles. A word from outside science is armigerous, entitled to bear heraldic arms (Latin arma, arms).

The word dangerous looks as though it includes the suffix but doesn’t because it’s from the Old French dangeros (a close relative of danger), which became dangerous after the Norman Conquest in the sense of arrogant or overbearing.
