The late Pennsylvanian fusulinids known in some of these boreholes, were not observed in BMT-1; however, these fusulinids are re-discussed here due to their biostratigraphic and palaeobiogeographic importance; they are assigned to two substages, early Gzhelian with Darvasoschwagerina spp. and late Kasimovian with …Fusulinid fossils in the limestone indicate that the rocks formed in the Late Permian or Early Triassic period. Most of the rocks that comprise the San Juan Islands are considered parts of accreted terranes. The rocks and their fossils speak of exotic origins, bits and pieces of the ocean floor and island arcs that came from far away. ...fusulinid fossils in the Kubergandian assemblage and Murghabian assemblage separation its describing as follow. 4.6.1. Kubergandian Assemblage. Fusulinids of this age in both north and south Afghanistan are more abundant and better studied than those of the Yahtashian and Bolorian. Fusulinids are the earliest lineage of foraminifera thought to have evolved symbiosis with photosynthetic organisms. Fossils of fusulinids have been found on all continents except Antarctica; they reached their greatest diversity during the Visean epoch of the Carboniferous. Fusulinids are larger benthic foraminifera of late Paleozoic and index fossils for Permo-Carboniferous strata. The traditional methods to examine their internal structures are through ground...

Sediment deposited in stagnant back-reef or lagoon waters often contained high amounts of magnesium, which combined with limestone to form the rock dolomite. Despite the high salinity, life forms were able to live in the back-reef. Brachiopods, crinoids and fusulinids are common fossils found in the back-reef sediments. Fore-reefAnalyses of taxa conWrm preliminary hypotheses of Cathaysian aYnities for brachiopods and fusulinids found in this part of Thailand. Fossils found in sandstones of the Nam Duk molasse facies, however, also show possible Gondwanan relationships with brachiopod taxa described in Australia.
