Where: Svalbard and Jan Mayen (79.8° N, 17.9° E: paleocoordinates 79.8° N, 17.9° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Olenidsletta Member (Valhallfonna Formation), Arenigian (478.6 - 468.1 Ma)

• "The stratigraphical horizon is c. 100 m above the base of the Olenidsletta Member of the Vallhalfonna Formation at the top of V2 in the terminology of Fortey (1980) and Arenig Series Ca 1 in Terms of graptolites (= North American D. bifidus zone, see Cooper and Fortey, 1982)." (Evans & King, 1990).

• group of beds-level stratigraphic resolution

Environment/lithology: black lime mudstone and coarse-grained, gray grainstone

• According to Fortey & Bruton (1973) 100 m above the base of the Olenidsletta Mbr. is within the middle part of the Member, characterized by "black, finely crystalline limestone beds and subordinate shale" alternating "in more or less regular fashion" with "gray, coarsely crystalline sparite beds".

Size class: macrofossils
