fossil vs modern
modern
'modern' and 'fossil' can form an opposite pair when 'fossil' is used colloquially for something completely outdated. 'modern' then means: new, current, and suited to the present day. In this use, 'fossil' sounds stronger and often derogatory, roughly like: This really no longer belongs in today’s world. Important: 'fossil' also has a technical meaning, for example with fossils or fossil fuels. In this contrast, however, it is about the figurative meaning 'outdated'.
fossil
