Where: Sumatra, Indonesia (1.8° S, 101.8° E: paleocoordinates 27.6° S, 116.8° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Silungkang Formation, Roadian to Roadian (272.3 - 264.3 Ma)
• There are two divisions: a lower slate with marl and pebbly shale, and an upper dark limestone. Fossils are from the upper division, and the presence of Verbeekina verbeeki suggests an early Guadalupian age.
• group of beds-level stratigraphic resolution
Environment/lithology: lithified, black, gray limestone
Size class: macrofossils
Collected by R.D.M. Verbeek in 1876
• Partially collected by Verbeek himself and partly by his officers
