genesis of the fusulinids occurred during compaction of the shale and is manifest as compression that has resulted in pressure solution and flattening. Pressure solution formed pits on 47 percent of the specimens, and another 3 percent have other fusulinids or fossil fragments embedded into them. Flattened or cracked specimens were not abundant,Other associated fossils comprised alatoconchid bivalves, gastropods, corals, brachiopods and crinoids. Microfacies of carbonate rocks and the occurrence of these fossils support a shallow-marine tropical depositional environment of the limestone sequence.

Washed, dried fossil samples can be picked from any remaining sediment using a fine brush and a reflected light, binocular microscope. The best method is to scatter a fine dusting of sieved sediment on to a black tray divided into squares, this can then be scanned under the microscope and any foraminifera preserved in the sediment can be picked ...

Bivalves are a class of mollusk with two valves, which is where they get their name (“bi” means two in Latin). They are the second-most common seashells in the world today behind their cousins, the gastropods (snails).
