Neogene
This term is a specialized geological designation used primarily in academic, paleontological, and stratigraphic contexts. It describes a specific window of Earth's history that bridges the gap between the older Paleogene period and the current Quaternary period. Because it refers to a unique, singular span of time, it is treated as a proper noun when referring to the period itself.
When used as an adjective, the word describes fossils, rock strata, or climatic conditions specific to this era. It is rarely encountered in general conversation and is almost exclusively reserved for scientific discourse regarding the evolution of mammals and the transition toward modern glacial cycles.
