Having the characteristics or appearance of a Gorgon; terrifying or petrifying in nature.
From Greek 'gorgos' (terrible) + Latin '-aceous' (full of, resembling). This Latin suffix became popular in English scientific and descriptive terminology.
Scientists use '-aceous' to name plant families (like Rosaceae for the rose family), so calling something 'gorgonaceous' is like saying it belongs to the Gorgon family of terrifying things!
