Oligocene
This term is a proper noun used exclusively within the field of geochronology and paleontology. It functions as a specific label for a geological time interval, and as such, it is always capitalized in professional and academic writing.
Because it refers to a unique, singular epoch in Earth's history, the word is used as a proper name rather than a common noun. It does not take a plural form and is not used as a countable entity in standard scientific discourse.
