"Upper" and "Lower" Imbrian

edit

The article uses the terminology of "upper" and "lower" Imbrian epochs, but the linked article for the Imbrian epoch uses the terminology "early" and "late" Imbrian. This is a confusing mix of terms, and it is not entirely clear that "lower" means "early". 129.242.81.177 (talk) 10:49, 12 December 2022 (UTC)Reply
