A geological time period or epoch characterized by particular climatic or biological conditions.
From Greek 'eu-' (well, good) + 'chronos' (time). The term appears in specialized geological terminology for distinct time intervals.
Geologists rarely use 'euchrone' anymore, but it represents an old way of thinking about Earth's history—dividing it into 'good times' and 'bad times' for life!
