Some deep water Middle Triassic foraminifera from the Semanggol Formation

Eight benthic foraminiferal taxa were retrieved from siliceous mudstone samples collected from the Semanggol Formation at Bukit Lada and Merbau Pulas. The foraminifera consist of Pseudonodosaria densa. Pseudonodosaria lata, Psuedonodosaria obconica, Pseudonodosaria simpsonensis, Prodentalina sp A, Prodentalina sp B, Cryptoseptida sp., and Protonodosaria spp. The assemblage indicates that the depositional environment was a deep marine basin above the calcite compensation depth
