Morphology

upper + Carboniferous

The compound is compositionally predictable: 'upper' denotes the higher/later part of a time scale and 'Carboniferous' names the geological period, so 'Upper Carboniferous' clearly means the later subdivision of that period. Although technical, this formation follows a common cross-linguistic naming pattern (Upper/Late vs Lower/Early), so a learner who knows both constituents will readily infer the meaning.

Etymology

Upper Carboniferous uses two simple ideas: Upper shows it is the 'later' or higher rock layers, and Carboniferous means a time when many plants turned into 'coal'. So the name refers to the later part of the Carboniferous period, when warm swamp forests grew and later formed large coal deposits.
