Morphology

lower + carboniferous

The phrase is a straightforward composition of 'lower' (earlier/positioned below) + 'Carboniferous' (the geological period), so its meaning as the earlier subdivision of the Carboniferous is directly derivable from the parts. This adjectival naming pattern is common in scientific and cross‑linguistic usage (e.g. 'Lower Jurassic', 'Carbonífero inferior'), making it transparent to a B1 learner who knows the constituents.

Etymology

Lower Carboniferous comes from Carboniferous, meaning 'coal-bearing', and lower, meaning the earlier or bottom part of the rock layers. So it names the earlier part of the Carboniferous period when many coal layers formed and early land plants and animals lived.
