Nice work, but WHY Carbon is shown as Mississippian and Pennsylvanyan "periods" (which are NOT periods)? :-/ 37.55.222.98 01:30, 5 July 2014 (UTC)[reply]

It's somewhat historical and specific to North American geology, but some still consider them is as periods. See Mississippian and Pennsylvanian. More at w:Period (geology)#Continuity issues. Mwtoews (talk) 01:10, 15 July 2014 (UTC)[reply]
