Morphology

Carboniferous + period

The meaning is directly compositional: 'Carboniferous' names a specific geological time interval (characterized by coal formation) and 'period' denotes a measured interval, so a learner who knows both constituents will readily infer it refers to that geological time. This follows common naming patterns for geological periods (e.g. Jurassic period), making the expression transparent to B1 learners who know the words.

Etymology

Carboniferous period comes from the parts carbon (meaning coal) and -iferous (meaning 'bearing' or 'carrying'). Huge swamp forests from that time later turned into coal, so the name means the period when much coal formed.
