Periods and systems
[edit]Geological periods are intervals of time - they can be divided into early, middle and late parts. The rock record laid down during a period is described as a 'system' - they can be divided into lower, middle and upper parts. See System (stratigraphy) and Chronostratigraphy#Differences from geochronology for example. thanks Geopersona (talk) 07:41, 9 September 2024 (UTC)
- (Did you take a look at all at my areas of editing?) Please see the vast volume of paleontological and paleobotanical which use the term "Upper Carboniferous" and the like.--Kevmin § 15:13, 9 September 2024 (UTC)
- @Geopersona: I've discussed this before when I tried to be precise about the terminology for periods of time versus rock systems, but the reality is that reliable sources do use terminology more loosely. See e.g. Britannica here, which has "the Upper Carboniferous Period began ...". Google Scholar gave me over 400 scientific sources using the exact phrase "Upper Carboniferous Period" versus over 700 for the more correct "Late Carboniferous Period". So given that Wikipedia is supposed to follow reliable sources, it seems acceptable to use lower, middle and upper for time periods, however much some of us may regret it, although nothing prevents the use of the more correct early, middle and late.

- Fair enough - its disappointing though. Geopersona (talk) 06:52, 10 September 2024 (UTC)
