Trigonictis macrodon is an extinct species of mammal related to the living grison "(genus Galictis)". The lesser grison is slightly smaller than the greater grison. Its NATO reporting name is SA-19 "Grison". Compare the word "Galictis" (grison, a closer relative of the weasel). The lesser grison ("Galictis cuja") is a species of mustelid from South America. The greater grison ("Galictis vittata") has also been recorded, but apparently in error. The Grison Alps include parts of both the Eastern Alps and the Western Alps.
