Makkol (Ordovician to of South Korea)

Also known as Maggol, Makgol, Sangdong; Taebaeksan Basin

Where: Kangwon-do, South Korea (37.2° N, 128.7° E: paleocoordinates 5.8° S, 132.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Duwibong Formation (Taebaek Group), Llanvirn to Llanvirn (468.0 - 460.9 Ma)

• The Duwibong Formation is a subunit of the Taebaek Group (includes the former "Great Limestone Group", cf. e.g. Lee, 2004, Alcheringa 28; and Woo & Chough, 2005, Geosci. J. 11(4)) and is Llanvirnian to Lower Llandeilo in age (Woo & Chough, 2005).

•Formation name was originally entered as >> Tsuibon <<. This appears to be the old name for the Duwibong Formation (Kobayashi in a 1977 paper [Proc. Japan Acad. B 53] lists the names Tsuibon and Duwi-bong for the same place/locality in Kangwon Province).

•Name of group was added to the original record (TL).

• formation-level stratigraphic resolution

Environment/lithology: limestone

Size class: macrofossils
