概要 |
The present paper deals only with the systematic paleontology of the rich faunas collected from the B Formation of the Khao Phlong Phrab section, Amphoe Phra Butthabat, Changwat Sara Buri in Central T...hailand. The fusuline fauna contains 91 species of 26 genera comprising Ozawainella, Toriyamaia, Neofusulinella, Yangchienia, Schwagerina, Pseudofusulina, Parafusulina, Monodiexodina, Chusenella, Misellina, Brevaxina, Verbeekina (Armenia), Verbeekina (Verbeekina), Verbeekina (Paraverbeekina), Pseudodoliolina, Metadoliolina, Cancellina, Presumatrina, Maklaya, Neoschwagerina, Colania, Nankinella, Sphaerulina, Eoverbeekina, Thailandina, and Neothailandina. The present paper describes 66 species including 9 new species and subspecies of the above-mentioned genera except for the species of Neofusulinella, Maklaya, Thailandina, and Neothailandina which were already described. The Khao Phlong Phrab fusuline fauna bears, as a whole, typical Tethyan aspects and furnishes a good key to a consideration of the phylogenetical development of fusulines, especially that of verbeekinids, neoschwagerinids and thailandinids in the late Early to the middle Middle Permian times.続きを見る
