Talk:Joli Fou Formation

Joli Fou formation over Mannville Group
From this article: "The Joli Fou Formation is the basal (oldest) formation of the Colorado Group. It is overlain by the Viking Formation (disconformably in south-eastern Saskatchewan) and conformably underlain by the upper Mannville Group".

From the Mannville Group article: "The Mannville Group is discomformably overlain by the Joli Fou Formation shale of the Colorado Group."

Seems we have a contradiction here. Someone knowledgeable like to sort this out? 2001:56A:F0E9:9B00:CA7:5A67:7BF9:BA74 (talk) 20:59, 29 June 2021 (UTC)JustSomeWikiReader
