Morphology
upper + Carboniferous + period
The phrase is fully compositional: 'upper' indicates the later/higher part, 'Carboniferous' names the geological period, and 'period' denotes a time interval, so together they mean the later subdivision of the Carboniferous. This follows common naming patterns (e.g. Upper/Lower + geological period) that are cross-linguistically familiar, so a learner who knows the constituents can infer the meaning.
Etymology
Upper Carboniferous period comes from the name Carboniferous, which points to a time when many 'coal' layers formed, and the word Upper marks the later part of that time. So the name tells us it is the later, warm, swampy age long ago when a lot of coal was made.
